A Look at Your Computer Business Computer Information Systems I Created by: Mrs. E. Kelley Revised: August 28, 2015
Learning Objectives To learn the difference between hardware and software. To learn the most important parts of your computer. To learn how computers work: – Input – Output – Processing – Storage
Hardware vs. Software Hardware is any part of a computer system you can see or touch. What do you see? Answer:A Printer
Hardware vs. Software Software is a set of electronic instructions that tell a computer what to do. You cannot see or touch software, but you can see and touch the packaging it comes in. What software do you see? Answer:Microsoft Office XP
Application Software Lets you accomplish specific tasks. Popular software include: Microsoft Word Microsoft Excel Microsoft Powerpoint Microsoft Access Application Suite

Identifying Parts of the Computer Monitor CPU Keyboard Mouse A typical computer system consist of several parts.
Monitor A monitor is a device that displays text and images generated by the computer.
CPU The main chip in a computer. Processes instructions, performs calculations and manages the flow of information through computer.
Keyboard A keyboard is a device that lets you type information and instructions into a computer.
Mouse A mouse is a hand-held device that lets you select and move items on the screen.
How Computers Work Input Output Processing Storage A computer collects, processes, stores and outputs information.
Input An input device lets you communicate with a computer. You can use input devices to enter information and issue commands. Examples include: keyboard, mouse, trackball, pointing stick, touchpad, touch screen, graphics tablet, scanner, digital camera and joystick.
Output An output device lets a computer communicate with you. These devices display information on a screen, create printed copies or generate sound. Examples include: a monitor, printer, headphones, plotter, projection unit, and speakers.
Processing The CPU is the main chip in a computer. It processes instructions, performs calculations and manages the flow of information. Communicates with input, output and storage devices to perform tasks.
Store A storage device holds information. The computer uses information stored on these devices to perform tasks. Examples include: hard drive, floppy disk, zip cartridge, DVD-ROM and CD-ROM.
