Chapter 1 – Operating System

These Chapter 1 notes have:

  • Give a brief introduction to the operating system.
  • The earliest computers were programmed without an operating system. The user would prepare his or her program on paper (often coding in machine language), then enter it into the computer using switches and press “start.”
  • If a mistake was made in setting up the switches, or if there was a problem with a calculation, the only way to correct it was to start over again from scratch. 
  • As applications grew more sophisticated and programming languages became more abstracted from machine language, people began to write compilers so that the source code could be entered once, compiled into machine language and then executed repeatedly without having to set up the switch.
  • Operating systems act as an intermediary between the user and the computer hardware. An operating system is an assortment of programs written by programmers. The CPU executes all kinds of programs, acting as an intermediary between the user of a computer and the computer hardware.
  • The dominant desktop operating system is Microsoft Windows with a market share of around 82.74%, Mac OS X by Apple Inc. has a market share of around 9.81% while Linux has about 0.99%. In the mobile sector, use in 2017 is up to 70% of Google’s Android and 28.5% for Apple’s iOS.
