What is Linux_- A Linux OS Introduction

Linux is an operating system (OS), like Windows. Think of there being two general types of software: operating system software and "other" software. The "other" software consists of several types of software programs, including: application software programs (like word processors, spreadsheets and email programs), utility software programs and server programs. All of the "other" software runs "on top of" an operating system, such as Windows or Linux. You boot a computer system with operating system software so you can run application software programs, like a word processor, spreadsheet, email, and browser.
