Message Send Protocol

topic

The Message Send Protocol (MSP) is an application layer protocol used to send a short message between nodes on a network. The original version of the protocol was published in 1990.[1] It was updated as Message Send Protocol 2 in 1992.[2] TCP-based service One message send service is defined as a connection-based application on TCP. A service listens for TCP connections on port 18. Once a connection is established, a short message is transmitted from the sender to the receiver over the connection. The sender closes the connection after sending the message. UDP-based service Another message send service is defined as a datagram-based application on UDP. A service listens for UDP datagrams on port 18. When a datagram is received by the receiver, an answering datagram is sent back to the sender containing exactly the same data.

Multimedia Messaging Service

topic

Multimedia Messaging Service (MMS) is a standard way to send messages that include multimedia content to and from a mobile phone over a cellular network. Users and providers may refer to such a message as a PXT, a picture message, or a multimedia message.[1] The MMS standard extends the core SMS (Short Message Service) capability, allowing the exchange of text messages greater than 160 characters in length. Unlike text-only SMS, MMS can deliver a variety of media, including up to forty seconds of video, one image, a slideshow[2] of multiple images, or audio. The most common use involves sending photographs from camera-equipped handsets. Media companies have utilized MMS on a commercial basis as a method of delivering news and entertainment content, and retailers have deployed it as a tool for delivering scannable coupon codes, product images, videos, and other information. The 3GPP and WAP groups fostered the development of the MMS standard, which is now continued by the Open Mobile Alliance (OMA). History

SMS

topic

E.161, a common mobile keypad alphabet layout SMS (short message service) is a text messaging service component of most telephone, Internet, and mobile device systems.[1] It uses standardized communication protocols to enable mobile devices to exchange short text messages. An intermediary service can facilitate a text-to-voice conversion to be sent to landlines.[2] SMS was the most widely used data application at the end of 2010, with an estimated 3.5 billion active users, or about 80% of all mobile subscribers.[1] SMS, as used on modern devices, originated from radio telegraphy in radio memo pagers that used standardized phone protocols. These were defined in 1985 as part of the Global System for Mobile Communications (GSM) series of standards.[3] The first SMS message was sent in 1992.[4] The protocols allowed users to send and receive messages of up to 160 characters (when entirely alpha-numeric) to and from GSM mobiles.

The Short Message Service is realised by the use of the Mobile Application Part (MAP) of the SS7 protocol, with Short Message protocol elements being transported across the network as fields within the MAP messages.[1] These MAP messages may be transported using "traditional" TDM based signalling, or over IP using SIGTRAN and an appropriate adaptation layer. Protocol The Short Message protocol itself is defined by 3GPP TS 23.040 for the Short Message Service - Point to Point (SMS-PP),[2] and 3GPP TS 23.041 for the Cell Broadcast Service (CBS).[3] Four MAP procedures are defined for the control of the Short Message Service:[1] Mobile Originated (MO) short message service transfer; Mobile Terminated (MT) short message service transfer; Short message alert procedure; Short message waiting data set procedure.

Geheime Korrespondenz (secret correspondence), by Carl von Bergen A headstone message in the Jerusalem British World War I Cemetery on Mount Scopus A message is a discrete unit of communication intended by the source for consumption by some recipient or group of recipients. A message may be delivered by various means, including courier, telegraphy, carrier pigeon and electronic bus. A message can be the content of a broadcast. An interactive exchange of messages forms a conversation. One example of a message is a communiqué , which is a brief report or statement released by a public agency. Roles in human communication In communication between humans, messages can be verbal or nonverbal: A verbal message is an exchange of information using words. Examples include face-to-face communication, telephone calls, voicemails, etc. A nonverbal message is communicated through actions or behaviors rather than words, e.g. by the use of body language.

A text message as it appears on the display screen of an iPhone before iOS 7. Text messaging, or texting, is the act of composing and sending electronic messages, typically consisting of alphabetic and numeric characters, between two or more users of mobile devices, desktops/laptops, or other type of compatible computer. Text messages may be sent over a cellular network, or may also be sent via an Internet connection. The term originally referred to messages sent using the Short Message Service (SMS). It has grown beyond alphanumeric text to include multimedia messages (known as MMS) containing digital images, videos, and sound content, as well as ideograms known as emoji (happy faces, sad faces, and other icons). Text messages are used for personal, family, business and social purposes. Governmental and non-governmental organizations use text messaging for communication between colleagues.

Java Message Service

topic

The Java Message TSC Service (JMS) API is a Java message-oriented middleware API for sending messages between two or more clients.[1] It is an implementation to handle the producer–consumer problem. JMS is a part of the Java Platform, Enterprise Edition (Java EE), and was defined by a specification developed at Sun Microsystems, but which has since been guided by the Java Community Process.[2] It is a messaging standard that allows application components based on Java EE to create, send, receive, and read messages. It allows the communication between different components of a distributed application to be loosely coupled, reliable, and asynchronous.[3] General idea of messaging Messaging is a form of loosely coupled distributed communication, where in this context the term 'communication' can be understood as an exchange of messages between software components. Message-oriented technologies attempt to relax tightly coupled communication (such as TCP network sockets, CORBA or RMI) by the introduction of an i

Internet Control Message Protocol

topic

The Internet Control Message Protocol (ICMP) is a supporting protocol in the Internet protocol suite. It is used by network devices, including routers, to send error messages and operational information indicating success or failure when communicating with another IP address, for example, an error is indicated when a requested service is not available or that a host or router could not be reached.[1] ICMP differs from transport protocols such as TCP and UDP in that it is not typically used to exchange data between systems, nor is it regularly employed by end-user network applications (with the exception of some diagnostic tools like ping and traceroute). ICMP for IPv4 is defined in RFC 792. Technical details ICMP is part of the Internet protocol suite as defined in RFC 792. ICMP messages are typically used for diagnostic or control purposes or generated in response to errors in IP operations (as specified in RFC 1122). ICMP errors are directed to the source IP address of the originating packet.[1] For exa

SWIFT Message types are the format or schema used to send messages to financial institutions on the SWIFT (Society for Worldwide Interbank Financial Telecommunication) network. The original message types were developed by SWIFT and retrospectively made into an ISO standard, ISO 15022. This was later supplemented by a XML based version under ISO 20022. The SWIFT network supports the following message standards:[1] SWIFT MT 103 field 23 SWIFT messages consist of five blocks of the data including three headers, message content, and a trailer. Message types are crucial to identifying content. All SWIFT messages include the literal "MT" (Message Type). This is followed by a three-digit number that denotes the message category, group and type. Consider the following example, which is an order to buy or sell via a third party: Example 1 : MT304 The first digit (3) represents the category. A category denotes messages that relate to particular financial instruments or services such as Precious Metals (6), Treas

Message passing

topic

In computer science, message passing is a technique for invoking behavior (i.e., running a program) on a computer. The invoking program sends a message to a process (which may be an actor or object) and relies on the process and the supporting infrastructure to select and invoke the actual code to run. Message passing differs from conventional programming where a process, subroutine, or function is directly invoked by name. Message passing is key to some models of concurrency and object-oriented programming. Message passing is used ubiquitously in modern computer software. It is used as a way for the objects that make up a program to work with each other and as a means for objects and systems running on different computers (e.g., the Internet) to interact. Message passing may be implemented by various mechanisms, including channels. Overview Message passing is a technique for invoking behavior (i.e., running a program) on a computer.

The at sign, a part of every SMTP email address[1] Electronic mail (email or e-mail) is a method of exchanging messages ("mail") between people using electronic devices. Invented by Ray Tomlinson, email first entered limited use in the 1960s and by the mid-1970s had taken the form now recognized as email. Email operates across computer networks, which today is primarily the Internet. Some early email systems required the author and the recipient to both be online at the same time, in common with instant messaging. Today's email systems are based on a store-and-forward model. Email servers accept, forward, deliver, and store messages. Neither the users nor their computers are required to be online simultaneously; they need to connect only briefly, typically to a mail server or a webmail interface for as long as it takes to send or r

Simple Mail Transfer Protocol

topic

The Simple Mail Transfer Protocol (SMTP) is a communication protocol for electronic mail transmission. As an Internet standard, SMTP was first defined in 1982 by RFC 821, and updated in 2008 by RFC 5321 to Extended SMTP additions, which is the protocol variety in widespread use today. Mail servers and other message transfer agents use SMTP to send and receive mail messages. Proprietary systems such as Microsoft Exchange and IBM Notes and webmail systems such as Outlook.com, Gmail and Yahoo! Mail may use non-standard protocols internally, but all use SMTP when sending to or receiving email from outside their own systems. SMTP servers commonly use the Transmission Control Protocol on port number 25. User-level email clients typically use SMTP only for sending messages to a mail server for relaying, typically submit outgoing email to the mail server on port 587 or 465 as per RFC 8314. For retrieving messages, IMAP and POP3 are standard, but proprietary servers also often implement proprietary protocols, e.g., E

Paxos (computer science)

topic

Paxos is a family of protocols for solving consensus in a network of unreliable processors (that is, processors that may fail). Consensus is the process of agreeing on one result among a group of participants. This problem becomes difficult when the participants or their communication medium may experience failures.[1] Consensus protocols are the basis for the state machine replication approach to distributed computing, as suggested by Leslie Lamport[2] and surveyed by Fred Schneider.[3] State machine replication is a technique for converting an algorithm into a fault-tolerant, distributed implementation. Ad-hoc techniques may leave important cases of failures unresolved. The principled approach proposed by Lamport et al. ensures all cases are handled safely. The Paxos protocol was first published in 1989 and named after a fictional legislative consensus system used on the Paxos island in Greece.[4] It was later published as a journal article in 1998.[5] The Paxos family of protocols includes a spectrum of

SMS gateway

topic

An SMS gateway or MMS gateway allows a computer to send or receive Short Message Service (SMS) or Multimedia Messaging Service (MMS) transmissions to or from a telecommunications network. Most messages are eventually routed into the mobile phone networks. Many SMS gateways support media conversion from email and other formats. Gateway types Several mobile telephone network operators have true fixed-wire SMS services. These are based on extensions to the European Telecommunications Standards Institute (ETSI) Global System for Mobile Communications (GSM) SMS standards and allow messaging between any mix of fixed and mobile equipment. These use frequency-shift keying to transfer the message between the terminal and the Short Message Service Center (SMSC). Terminals are usually based on Digital Enhanced Cordless Telecommunications (DECT), but wired handsets and wired text-only (no voice) devices exist. Messages are received by the terminal recognising that the Caller ID is that of the SMSC and going off-hook si

F-Script is an object-oriented scripting programming language for Apple's macOS operating system developed by Philippe Mougin. F-Script is an interactive language based on Smalltalk, using macOS's native Cocoa API. Overview F-Script is based on a pure object paradigm: every entity manipulated within the language is an object. Its base syntax and concepts are identical to those of the language Smalltalk (the canonical example of an object-oriented language) with specific extensions to support array programming as in the language APL. F-Script provides an interpreted, interactive environment with support for workspaces, which provide a rich set of functions including object persistence, distributed objects, graphical user interface (GUI) framework, database access, among other things. Syntax Like Smalltalk, F-Script's syntax is very simple, without requiring specific notation for control structures which are provided in a unified manner by the message send operation.

Email marketing is the act of sending a commercial message, typically to a group of people, using email. In its broadest sense, every email sent to a potential or current customer could be considered email marketing. It usually involves using email to send advertisements, request business, or solicit sales or donations, and is meant to build loyalty, trust, or brand awareness. Marketing emails can be sent to a purchased lead list or a current customer database. The term usually refers to sending email messages with the purpose of enhancing a merchant's relationship with current or previous customers, encouraging customer loyalty and repeat business, acquiring new customers or convincing current customers to purchase something immediately, and sharing third-party ads.

A LAN messenger operates in a similar way over a local area network. Short messages are typically transmitted between two parties, when each user chooses to complete a thought and select "send". Some IM applications can use push technology to provide real-time text, which transmits messages character by character, as they are composed. More advanced instant messaging can add file transfer, clickable hyperlinks, Voice over IP, or video chat. Non-IM types of chat include multicast transmission, usually referred to as "chat rooms", where participants might be anonymous or might be previously known to each other (for example collaborators on a project that is using chat to facilitate communication).

This bottle and its contents (sample postcard and insert shown above) were launched in 1959 as part of the U.S. Coast and Geodetic Survey, and were found in 2013.[1] A message in a bottle is a form of communication in which a message is sealed in a container (typically a bottle) and released into a conveyance medium (typically a body of water). Messages in bottles have been used to send distress messages, in crowdsourced scientific studies of ocean currents, as memorial tributes, to send deceased loved ones' ashes on a final journey, to convey expedition reports, and to carry letters or reports from those believing themselves to be doomed. Invitations to prospective pen pals and letters to actual or imagined love interests have also been sent as messages in bottles.

topic

A bounce message or just "bounce" is an automated message from an email system, informing the sender of a previous message that message had not been delivered (or some other delivery problem occurred). The original message is said to have "bounced". More formal terms for bounce message include "Non-Delivery Report" or "Non-Delivery Receipt" (NDR), [Failed] "Delivery Status Notification" (DSN) message, or a "Non-Delivery Notification" (NDN). Delivery errors Errors may occur at multiple places in mail delivery. A sender may sometimes receive a bounce message from their own mail server, reporting that it has been unable to send a message, or alternatively from a recipient's mail server reporting that although it had accepted the message, it is unable to deliver it to the specified user. When a server accepts a message for delivery, it is also accepting the responsibility to deliver a bounce message in the event that delivery fails.

Message authentication

topic

In information security, message authentication or data origin authentication is a property that a message has not been modified while in transit (data integrity) and that the receiving party can verify the source of the message.[1] Message authentication does not necessarily include the property of non-repudiation.[2][3] Message authentication is typically achieved by using message authentication codes (MACs), authenticated encryption (AE) or digital signatures.[2] The message authentication code, also known as digital authenticator, is used as an integrity check based on a secret key shared by two parties to authenticate information transmitted between them.[4] It is based on using a cryptographic hash or symmetric encryption algorithm.[5] The authentication key is only shared by at least two parties or two communicating devices but it will fail in the existence of a third party since the algorithm will no longer be effective in detecting forgeries.[6] In addition, the key must also be randomly generated t

Syslog

topic

In computing, syslog is a standard for message logging. It allows separation of the software that generates messages, the system that stores them, and the software that reports and analyzes them. Each message is labeled with a facility code, indicating the software type generating the message, and assigned a severity level. Computer system designers may use syslog for system management and security auditing as well as general informational, analysis, and debugging messages. A wide variety of devices, such as printers, routers, and message receivers across many platforms use the syslog standard. This permits the consolidation of logging data from different types of systems in a central repository. Implementations of syslog exist for many operating systems. History Syslog was developed in the 1980s by Eric Allman as part of the Sendmail project.[1] It was readily adopted by other applications and has since become the standard logging solution on Unix-like systems. A variety of implementations also exist on o

Message queue

topic

In computer science, message queues and mailboxes are software-engineering components used for inter-process communication (IPC), or for inter-thread communication within the same process. They use a queue for messaging – the passing of control or of content. Group communication systems provide similar kinds of functionality. The message queue paradigm is a sibling of the publisher/subscriber pattern, and is typically one part of a larger message-oriented middleware system. Most messaging systems support both the publisher/subscriber and message queue models in their API, e.g. Java Message Service (JMS). Overview Message queues provide an asynchronous communications protocol, meaning that the sender and receiver of the message do not need to interact with the message queue at the same time. Messages placed onto the queue are stored until the recipient retrieves them. Message queues have implicit or explicit limits on the size of data that may be transmitted in a single message and the number of messages th

Message Passing Interface

topic

Message Passing Interface (MPI) is a standardized and portable message-passing standard designed by a group of researchers from academia and industry to function on a wide variety of parallel computing architectures. The standard defines the syntax and semantics of a core of library routines useful to a wide range of users writing portable message-passing programs in C, C++, and Fortran. There are several well-tested and efficient implementations of MPI, many of which are open-source or in the public domain. These fostered the development of a parallel software industry, and encouraged development of portable and scalable large-scale parallel applications. History The message passing interface effort began in the summer of 1991 when a small group of researchers started discussions at a mountain retreat in Austria. Out of that discussion came a Workshop on Standards for Message Passing in a Distributed Memory Environment held on April 29–30, 1992 in Williamsburg, Virginia[1]. Attendees at Williamsburg discus

Motd (Unix)

topic

Default motd showing on OpenBSD 5.3 The /etc/motd is a file on Unix-like systems that contains a "message of the day", used to send a common message to all users in a more efficient manner than sending them all an e-mail message. Other systems might also have an motd feature, such as the motd info segment on MULTICS.[1] Usage The contents of the file /etc/motd are displayed by the Unix login command after a successful login, and just before it executes the login shell.[2] Newer unix-like systems may generate the message dynamically when the host boots or a user logs in.[3] The MOTD has also become a common feature of the online component of Windows PC games, such as Half-Life, Call of Duty, and Battlefield. A similar feature called MOTD is displayed when logging on to some IRC servers.[4] See also System console References http://multicians.org/mgm.html The complete FreeBSD: documentation from the source, By Greg Lehey, p.572 https://books.google.com/books?id=gpbk66Y_s5sC&pg=PA269&

Status message (instant messaging)

topic

Status box on Facebook, where users type a status to be posted to their timeline A status message is a function of some instant messaging applications whereby a user may post a message that appears automatically to other users if they attempt to make contact. A status message can tell other contacts the user's current status, such as being busy or what the user is currently doing. [1] It is analogous to the voice message in an answering machine or voice mail system. However, status messages may be displayed even if the person is present. They are often updated much more frequently than messages in answering machines, and thus may serve as a means of instant, limited "publication" or indirect communication. Generally Available status is denoted by a green dot while the busy status is denoted by a red dot on most of the Instant Messengers Whereas answering machine or voice mail messages often have a generic greeting to leave a message, status messages more often contain a description of where the person is a

Sender-Message-Channel-Receiver Model of Communication

topic

In 1960, David Berlo expanded Shannon and Weaver's linear model of communication and created the Sender-Message-Channel-Receiver (SMCR) Model of Communication, which separated the model into clear parts and has been expanded upon by other scholars.[1] Berlo described factors affecting the individual components in the communication making the communication more efficient. Background The Berlo's Model of Communication has developed from Claude Shannon and Warren Weaver's mathematical model, which was first published in “Bell System Technical Journal” in 1948. The model was primary designed to improve the technical communication, but was later widely applied in different fields of communication.[2] According to the Shannon-Weaver Model, communication includes the following concepts: sender, encoder, channel, decoder, receiver and feedback. Furthermore, there is also concept of “noise”, which affects the communication process going through the channel and makes the message more difficult to understand by the re

Lamport timestamps

topic

The algorithm of Lamport timestamps is a simple algorithm used to determine the order of events in a distributed computer system. As different nodes or processes will typically not be perfectly synchronized, this algorithm is used to provide a partial ordering of events with minimal overhead, and conceptually provide a starting point for the more advanced vector clock method. They are named after their creator, Leslie Lamport. Distributed algorithms such as resource synchronization often depend on some method of ordering events to function. For example, consider a system with two processes and a disk. The processes send messages to each other, and also send messages to the disk requesting access. The disk grants access in the order the messages were sent. For example process A {\displaystyle A} sends a message to the disk requesting write access, and then sends a read instruction message to process B {\displaystyle B} . Process B {\displaystyle B} receives the message, and as a result sen

Message-oriented middleware

topic

Message-oriented middleware (MOM) is software or hardware infrastructure supporting sending and receiving messages between distributed systems. MOM allows application modules to be distributed over heterogeneous platforms and reduces the complexity of developing applications that span multiple operating systems and network protocols. The middleware creates a distributed communications layer that insulates the application developer from the details of the various operating systems and network interfaces. APIs that extend across diverse platforms and networks are typically provided by MOM.[1] This middleware layer allows software components (applications, Enterprise JavaBeans, servlets, and other components) that have been developed independently and that run on different networked platforms to interact with one another. Applications distributed on different network nodes use the application interface to communicate. In addition, by providing an administrative interface, this new, virtual system of interconnec

Message in a Bottle (song)

topic

"Message in a Bottle" is a song by English rock band The Police. It was released as the lead single from their second studio album, Reggatta de Blanc (1979). Written by the band's lead singer and bassist Sting, the song is ostensibly about a story of a castaway on an island, who sends out a message in a bottle to seek love. A year later, he has not received any sort of response, and despairs, thinking he is destined to be alone. The next day, he sees "a hundred billion bottles" on the shore, finding out that there are more people like him out there. American rock band American Hi-Fi performed a cover of the song for the 2003 film Rugrats Go Wild. The song was the first of their five UK number one singles.[1] Rolling Stone ranked it number 65 on its list of the "100 Greatest Guitar Songs of All Time". Background According to the band's guitarist, Andy Summers, Sting had initially intended the guitar riff that "Message in a Bottle" is centred around for a different song.[2] Summers said to L'Historia Bandidi

Alternating bit protocol

topic

Alternating bit protocol (ABP) is a simple network protocol operating at the data link layer (OSI layer 2) that retransmits lost or corrupted messages using FIFO semantics. It can be seen as a special case of a sliding window protocol where a simple timer restricts the order of messages to ensure receivers send messages in turn while using a window of 1 bit.[1] Messages are sent from transmitter A to receiver B. Assume that the channel from A to B is initialized and that there are no messages in transit. Each message from A to B contains a data part and a one-bit sequence number, i.e., a value that is 0 or 1. B has two acknowledge codes that it can send to A: ACK0 and ACK1. When A sends a message, it resends it continuously, with the same sequence number, until it receives an acknowledgment from B that contains the same sequence number. When that happens, A complements (flips) the sequence number and starts transmitting the next message. When B receives a message that is not corrupted and has sequence numb

Messages (Apple)

topic

Messages is an instant messaging software application developed by Apple Inc. for its macOS, iOS and watchOS operating systems. The desktop Messages application replaced iChat as the native OS X instant messaging client with the release of OS X Mountain Lion in July 2012.[1] While it inherits the majority of iChat's features, Messages also brings support for iMessage, Apple's messaging service for iOS, as well as FaceTime integration. The mobile version of Messages on iOS used on iPhone and iPad also supports SMS and MMS due to replacing the older text messaging Text app since iOS 3. Users can tell the difference between a message via SMS and one sent over iMessage as the bubbles will appear either green (SMS) or blue (iMessage). iOS version iPhone OS 3 Apple released Messages for the iPhone as a built-in application with iPhone OS 3.0 on June 17, 2009.[2] It replaced the Text application which had been the native messaging application since the iPhone's inception.

Public warning alerts using embedded Cell Broadcast feature on Android 7.1 Cell Broadcast (CB) is a method of sending messages to multiple mobile telephone users in a defined area at the same time. It is defined by the ETSI’s GSM committee and 3GPP and is part of the 2G, 3G, 4G LTE (telecommunication) and 5G standards. It is also known as Short Message Service-Cell Broadcast (SMS-CB). Unlike Short Message Service-Point to Point (SMS-PP), Cell Broadcast is a one-to-many geo-targeted and geo-fenced messaging service. History Cell Broadcast messaging was first demonstrated in Paris in 1997. Some mobile operators use Cell Broadcast for communicating the area code of the antenna cell to the mobile user (via channel 050), for nationwide or citywide alerting, weather reports, mass messaging, location-based news, etc. Cell broadcast has been widely deployed since 2008 by major Asian, US, Canadian, South American and European network operators.

Personal message

topic

Personal message, private message (PM), direct message (DM),[1] or personal chat (PC) is a private form of messaging between different members on a given platform. It is only seen and accessible by the users participating in the message. It has grown popular because of the increasing demand for privacy and collaboration in this society where the public sharing domain dominates. There are two main types of personal message: a feature on social platforms and private messaging services. Twitter, Facebook, and Instagram are all examples in which social media included personal messaging features to provide space for private interactions among their users. WhatsApp9[2][3], Kik Messenger, and Snapchat are examples of pure private messaging tools. Users create and sign up for accounts to connect privately with selected friends. A third type of messaging platform is a peer-to-peer messaging platform where the users themselves own and create the infrastructure used to transmit and store the messages; while features va

SMS spoofing

topic

SMS spoofing is a technology which uses the short message service (SMS), available on most mobile phones and personal digital assistants, to set who the message appears to come from by replacing the originating mobile number (Sender ID) with alphanumeric text. Spoofing has both legitimate uses (setting the company name from which the message is being sent, setting your own mobile number, or a product name) and illegitimate uses (such as impersonating another person, company, product). This can also send "mysterious" messages that look like they are from legitimate numbers or contacts. How SMS spoofing is carried out SMS Spoofing occurs when a sender manipulates address information. Often it is done in order to impersonate a user that has roamed onto a foreign network and is submitting messages to the home network. Frequently, these messages are addressed to destinations outside the home network – with the home SMSC essentially being “hijacked” to send messages into other networks. In advanced cases they can

Apple Mail (officially known as simply Mail) is an email client included by Apple Inc. with its operating systems macOS, iOS and watchOS. Apple Mail grew out of NeXTMail, which was originally developed by NeXT as part of its NeXTSTEP operating system, after Apple's acquisition of NeXT in 1997. The current version of Apple Mail utilizes SMTP for message sending, POP3, Exchange and IMAP for message retrieval and S/MIME for end-to-end message encryption.[2][3] It is also preconfigured to work with popular email providers, such as Yahoo! Mail, AOL Mail, Gmail, Outlook and iCloud (formerly MobileMe) and it supports Exchange.[4] iOS features a mobile version of Apple Mail with added Exchange ActiveSync (EAS) support, though it notoriously missed the functionality of attaching files to reply emails until the release of iOS 9.[5] EAS is not supported in the macOS version of Apple's Mail app, the main issue being that sent messages will incorrectly be duplicated in the sent messages folder, which then propagates via

The Chandy–Lamport algorithm is a snapshot algorithm that is used in distributed systems for recording a consistent global state of an asynchronous system. It was developed by and named after Leslie Lamport and K. Mani Chandy.[1] History According to Leslie Lamport's website, “The distributed snapshot algorithm described here came about when I visited Chandy, who was then at the University of Texas in Austin. He posed the problem to me over dinner, but we had both had too much wine to think about it right then. The next morning, in the shower, I came up with the solution. When I arrived at Chandy's office, he was waiting for me with the same solution.” Definition The assumptions of the algorithm are as follows: There are no failures and all messages arrive intact and only once The communication channels are unidirectional and FIFO ordered There is a communication path between any two processes in the system Any process may initiate the snapshot algorithm The snapshot algorithm does not interfere wit

List of TCP and UDP port numbers

topic

This is a list of TCP and UDP port numbers used by protocols of the Internet protocol suite for operation of network applications. The Transmission Control Protocol (TCP) and the User Datagram Protocol (UDP) needed only one port for full-duplex, bidirectional traffic. The Stream Control Transmission Protocol (SCTP) and the Datagram Congestion Control Protocol (DCCP) also use port numbers. They usually use port numbers that match the services of the corresponding TCP or UDP implementation, if they exist. The Internet Assigned Numbers Authority (IANA) is responsible for maintaining the official assignments of port numbers for specific uses.[1] However, many unofficial uses of both well-known and registered port numbers occur in practice. Similarly many of the official assignments refer to protocols that were never or are no longer in common use.
