Linux is a modular system, which means all its components are separate from one another. This design makes it possible for different teams to develop components that don’t affect one another. For instance, one team might update the kernel, and another team might create applications. In fact, you can create applications that meet your own needs or even contribute to the Linux kernel. A Linux distribution, such as openSUSE 11.2, consists of all the Linux components put together and released as one OS.

Vi follows its beginnings back to the most punctual direction line supervisor utilized in Unix frameworks called ed. Ed worked incredibly well with prints yet wasn't appropriate for show terminals. Many individuals considered ed antagonistic and willingly volunteered to make a superior variant. Among them is George Coulouris, at the time a speaker at Queen Mary College, who made em, the proofreader intended for show terminals.

In 1976, he visited UC Berkeley and demonstrated em to different individuals. The responses were blended however several understudies, Bill Joy and Chuck Haley, were intrigued with em and utilized it as the base for their own proofreader called en which was then reached out to make ex adaptation 0.1. After Haley left Berkeley, Joy upgraded the editorial manager in 1977, when he included a full-screen visual mode to ex, permitting content to be seen on a full screen as opposed to just each line in turn.

Ex 1.1 was authoritatively remembered for the first BSD Unix discharge in 1978 and it got known as vi after the arrival of ex 2.0 as a major aspect of the second Berkeley Software Distribution in 1979 when the proofreader was introduced under the name "vi" since it consequently brought clients straight into ex's visual mode.
