Program Plan Intro

Operating System (OS):

• The most important program that runs on a computer is operating system.
• OS is the term that acts as an interface between the hardware and the user.
• It is the first program loaded into the computer memory whenever the computer starts up.
• It is responsible for the management to co-ordinate the activities on a computer system.
• OS does basic operations such as getting input from the keyboard, displaying output in the monitor and monitoring the files.
• OS controls the peripheral devices like printers, hard drives and mouse.
• The responsibilities of OS are bound to get higher when it comes to security, because it provides the access rights for users.
