Ubuntu is a computer operating system based on the Debian Linux distribution and distributed as free and open source software, using its own desktop environment. It is named after the Southern African philosophy of ubuntu (“humanity towards others”). As of 2012, according to online surveys, Ubuntu is the most popular Linux distribution on desktop/laptop personal computers, and most Ubuntu coverage focuses on its use in that market.

Ubuntu is sponsored by the UK-based company Canonical Ltd., owned by South African entrepreneur Mark Shuttleworth. Canonical generates revenue by selling technical support and services related to Ubuntu, while the operating system itself is entirely free of charge.KrnDf

Unix was created in 1969 by Dennis Ritchie (also the creator of C programming language) & Ken Thompson

Slowly, an open operating system standardisation was thought of that led to the birth of POSIX (Portable Operating System Interface). The first POSIX standard was published in 1988

Then came 1991, when a college student in University of Helsinki decided to write his own operating system because he wanted a “powerful & Free Unix system“. His name was Linus Torvalds and he developed the 1st version of this new OS ( LINUX ) that was powered by Intel’s 80386 microprocessor (a 32 bit microprocessor launched in 1985)

Unlike other Unix systems, Linux is not a direct descendant of Unix source code. It implements Unix Application Programming Interface (API) defined by POSIX, but is classified as “Mostly POSIX-compliant” & not “Fully-POSIX compliant”
