After a long illness, Dennis Ritchie, father of Unix and an esteemed computer scientist, died last weekend at the age of 70. Ritchie, also known as “dmr”, is best know for creating the C programming language as well as being instrumental in the development of UNIX along with Ken Thompson.
Who invented UNIX?
In 1969 a team led by computer scientists Ken Thompson and Dennis Ritchie created the first version of UNIX on a PDP-7 minicomputer, which was chosen mainly because of Thompson’s familiarity with the system from his hobby work on it.
What is the original name of UNIX?
In 1970, the group coined the name Unics for Uniplexed Information and Computing Service as a pun on Multics, which stood for Multiplexed Information and Computer Services. Brian Kernighan takes credit for the idea, but adds that “no one can remember” the origin of the final spelling Unix.
Who is the father of programming?

When was UNIX created?

What Unix means?
Unix is a portable, multitasking, multiuser, time-sharing operating system (OS) originally developed in 1969 by a group of employees at AT&T. Unix was first programmed in assembly language but was reprogrammed in C in 1973. Unix has been ported to more machine families than any other operating system.
Who uses Unix?
Proprietary Unix operating systems (and Unix-like variants) run on a wide variety of digital architectures, and are commonly used on web servers, mainframes, and supercomputers. In recent years, smartphones, tablets, and personal computers running versions or variants of Unix have become increasingly popular.
What language is Unix written in?
The UNIX operating system’s development started in 1969, and its code was rewritten in C in 1972. The C language was actually created to move the UNIX kernel code from assembly to a higher level language, which would do the same tasks with fewer lines of code.
Who founded Java?
BOSTON (Reuters) – James Gosling, creator of the Java computer language and one of the most prominent employees in Oracle Corp’s newly acquired Sun Microsystems, has resigned from Oracle.
Who invented Python?
When he began implementing Python, Guido van Rossum was also reading the published scripts from “Monty Python’s Flying Circus”, a BBC comedy series from the 1970s. Van Rossum thought he needed a name that was short, unique, and slightly mysterious, so he decided to call the language Python.
Who is the father of email?
Engineer Ray Tomlinson sent the first network email in 1971, choosing the ‘@’ symbol to separate the name of the sender from the address of the host computer.
Why is Unix called Unix?
In 1969 he wrote the first version of Unix, called UNICS. UNICS stood for Uniplexed Operating and Computing System. Although the operating system has changed, the name stuck and was eventually shortened to Unix. Ken Thompson teamed up with Dennis Ritchie, who wrote the first C compiler.
Who invented Android?
The full form of LINUX is Lovable Intellect Not Using XP. Linux was built by and named after Linus Torvalds. Linux is an open-source operating system for servers, computers, mainframes, mobile systems, and embedded systems.
