Introduction computer basics for PC
Using a computer is not such a daunting task, especially when you are more familiar with some of its basic operations. This job aid will help the computer novice glide smoothly through some basic operations useful in a PC Windows environment.


Parts of a computer
Before we begin looking at some basic functions of a PC, it would be useful to review a basic computer system and its components.
Monitor: This is what we call the screen. It is formally called a cathode-ray tube.
Keyboard: This is the instrument we use in order to type text into the computer.
Mouse: This attachment rolls on a small circular ball and has buttons which can be clicked. This part of the system allows the user to work more easily with a computer interface. As the user moves the mouse around on its pad, a screen cursor moves correspondingly on screen. Some later models of the mouse no longer use a ball but use optical light technology.
LCD: This is an acronym for Liquid Crystal Display Projector. This device permits users to project what appears on their computer screen to a larger classroom/ conference room screen.
CPU: This is an acronym for the Central Processing Unit. It is the ‘nuts and bolts’ of the computer and is where the computer’s memory and storage space exists.
Modem: This is a component that resides inside your CPU. It allows the user to connect with the Internet and the World Wide Web (WWW).
Desktop: This comprises of what is plainly visible on the user’s computer screen or monitor.
Peripherals: Peripherals refer to technology that can be attached to the main computer station, such as printers, scanners or digital cameras.
Printer: This peripheral is a device that permits users to print files (i.e., documents, pictures, etc..) to paper.
Scanner: This peripheral device permits the user to digitally upload images or text which already exist non-electronically. These digital uploads can then be converted into computer files which can be
manipulated.
Digital Camera: Digital Cameras can now be connected to computer stations. This is may be done so that the video can be uploaded to the computer which can then be edited.
