Other Datapoint inventions were ARCnet, invented in 1977, originally called ARC (Attached Resource Computer), which was an early token-passing local area network (LAN) protocol, and the PL/B high-level programming language, which was originally called Databus (from Datapoint business language) and ran under the Datashare multi-user interpreter.
Datapoint eventually found itself in financial trouble and moved into video conferencing then and later to custom programming in the embedded market. Even though ARCNET is now rarely used for new general networks, the diminishing installed base still requires support and it retains a niche in industrial control.
Developed in 1976, ARCNET (Attached Resource Computer NETwork) was the first widely available networking system for microcomputers. [1]Datapoint had pioneered microprocessors; the challenge ARCNET addressed was how to facilitate the efficient transmission of information between different machines. [6]
Programming Language for Business or PL/B is a business-oriented programming language originally called DATABUS and designed by Datapoint in 1972 [2] as an alternative to COBOL because Datapoint's 8-bit computers could not fit COBOL into their limited memory, and because COBOL did not at the time have facilities to deal with Datapoint's built-in keyboard and screen.
Victor "Vic" Poor (July 12, 1933 – August 17, 2012) was an American engineer and computer pioneer. At Computer Terminal Corporation (later renamed Datapoint Corporation), he co-created the architecture that was ultimately implemented in the first successful computer microprocessor, the Intel 8008.

Network programming traditionally covers different layers of OSI/ISO model (most of application-level programming belongs to L4 and up). The table below contains some examples of popular protocols belonging to different OSI/ISO layers, and popular APIs for them.
Computer programming or coding is the composition of sequences of instructions, called programs, that computers can follow to perform tasks. [1] [2] It involves designing and implementing algorithms, step-by-step specifications of procedures, by writing code in one or more programming languages.
