In 1969, a message was sent over the ARPANET, the predecessor of the modern internet, but a system crash limited it to just “lo”. The first official email was sent in 1971 by Ray Tomlinson, connecting 15 computers. The information age got off to a somewhat inauspicious start. Just three months after man first walked […]
Message switching is a slower data transfer method that sends the entire message as a unit, storing it temporarily on the hard drive. It is still used for email and has benefits such as lower bandwidth costs and better network congestion management. Messages are designated an address and inspected for errors at each hop until […]
SMB/CIFS is a protocol used for sharing files, ports, and printers on computer networks. It allows inter-process communication and is client-driven. SMB is comparable in speed to other protocols on LANs but has latency issues on WANs. It also increases broadcast traffic, causing delays and packet loss. A server message block (SMB), also known as […]
Java® Message Service is a module of Java® programming language used to transfer data quickly and efficiently. It’s commonly used by email, instant messaging, and SMS communications. JMS is based on message-oriented middleware and supports various messaging technologies. It’s widely used in business-to-business functions and is a standard messaging technology. Learning JMS requires special training […]
Message passing is a communication process used in computing, including object-oriented programming, inter-process communication, and parallel computing. It involves transmitting information between components using signals, data packets, or remote triggers. There are one-to-one and one-to-many messaging approaches, and synchronous message passing is a common method. It offers advantages such as not requiring a buffer and […]
Anonymous posting is when someone uses an alternate identity on an internet forum or blog for privacy reasons. They may use a nickname or alternate name and often choose an inanimate object as their avatar. Anonymous posting can be used to avoid offending someone or to intentionally post offensive material. It can also be used […]
Active messages are a type of inter-process communication used in computing that allow a subroutine or function to be executed by a different computer. They are asynchronous and can override existing IP network communication protocols, allowing for continuous overlapping of sent messages with computations on remote machines. Active messages are commonly used in parallel processing […]
A copyright notice should include the date and name of the owner, and “all rights reserved” is no longer necessary. No notice is needed to protect work, but it can help prevent violations. The official copyright symbol can be used. The value of the work determines the likelihood of winning a lawsuit. Online piracy is […]
A message authentication code (MAC) is a small block of data attached to a message to verify its integrity. The MAC is created at the same time as the message, and when the recipient opens it, the message content is run through an algorithm to create a new MAC, which is compared to the original. […]
The practice of sending messages in bottles dates back to ancient Greece, used by scientists to study ocean currents. Militaries also used it for communication, leading Queen Elizabeth I to appoint an Official Opener of Ocean Bottles. Today, it is used for social experiments and scientific studies, as well as a figurative term for communication […]
Message sticks were used by Aboriginal people in Australia as a non-verbal means of communication between tribes. They were made from wood and engraved with symbols, and were carried by couriers who were granted safe passage. Today, message sticks are still used as a cultural symbol and for identification purposes. A message stick was an […]
