Unix: A Complete Guide For Begineers

WHAT IS UNIX?

UNIX is an open-source technology. The software itself is an operating system, like Windows or Apple OS for Mac computers. It was developed by Finnish student and developer, Linus Torvalds, in 1991 whose motive was to produce a free operating system kernel for personal computers. It happened as expected, and that kernel has grown constantly over the years, modified, added to and used by thousands across the globe.

UNIX is developed closely on Linux, another widely used multi-user operating system. It is the leading operating system in use on servers, supercomputers and mainframe computers worldwide. It’s less widely used on desktop computers, but its popularity in that field has grown significantly in recent years.

UNIX OPERATING SYSTEMS

UNIX, an operating system similar to UNIX, is distributed under open source licenses meaning the following rules apply that make it attractive to enterprises:

• UNIX operating system is free to run.
• Administrators are able to study the OS and customize it for specific purposes.
• Unrestricted redistribution privileges of the original or modified versions of the operating system.

WHAT COMPONENTS MAKE UP UNIX?
