� Hardware - the physical components, both internal and external,that make up a computer.
� Operating System - a set of computer programs that managesthe hardware of a computer. An operating system controls theresources on a computer, including memory and disk storage.An example of an operating system is Windows XP.
Purpose and Uses of Personal Computers
4
An example of an operating system is Windows XP.
� Application Software - programs loaded on the computer toperform a specific function using the capabilities of thecomputer. An example of application software is a wordprocessor or a computer game.
Purpose and Uses of Personal Computers

Local and Network Applications
� Local application - A local application is a program, such as aword processor, that is stored on the hard disk of the computer.The application runs only on that computer.
� Network application - A network application is one that is

designed to run over a network, such as the Internet. A networkapplication has two components, one that runs on the localcomputer and one that runs on a remote computer. Email is anexample of a network application.
Identify the Motherboard, CPU, RAM, Power Supply, and Case
� Hardware Components
