This document defines and provides examples of computer hardware and software. It states that hardware refers to the physical parts of a computer like the monitor, keyboard, mouse, printer, and central processing unit. Software refers to computer programs and instructions that control the hardware. The document then explains the basic components of a computer system including input, output, storage and processing devices. It describes the information processing cycle where data is input, processed by the CPU, and then output. Finally, it discusses why computers are powerful due to their speed, reliability, accuracy, storage, versatility and communication abilities.

4. DEFINITION
• Hardware Vs. Software
If you can touch it, it’s hardware

5. Examples of Hardware
• Computer Hardware is the physical part of the computer system, the
machinery and equipment.
• Parts of the computer “you can see”. Physical devices of computer system

6. Examples of Computer Hardware
Monitor: T.V. like screen used to show pictures and
words. It lets you see your work and your files.
CPU: Central Processing Unit this is where most of
the computer’s calculations take place. In terms of
computing power, the CPU is the most important
element of a computing system. They contain the
brains of the computer. They can be desktop
models that the monitor sits on top of, or tower
models that stand up tall.

7. More Computer Hardware
Mouse: a small device, which you move across the top of
the desk to move the pointer or cursor on the screen.
Printer: used to make a paper copy of the information
into the computer.
Image Scanner: an electronic device that generates a
digital representation of an image for data input to a
computer
Keyboard: This device is used to type information
into the computer and contains the numbers 0-9.

8. The Programs that are on the disks are
software
• Computer Software are programs that tell the computer what
to do. Programs that run on computers. Sets of instructions
for which computer processes data
Example: MS Office
Computer Software

9. But how computer actually works!
• To understand, let’s break it down into it's basic components
• Then how each component works
• Finally how all the components work together to achieve the
desired end product or result

10. Input Devices
•Keyboard
•Mouse
•Trackball
•Stylus
Central Processing Unit (CPU)
•Microprocessor
•Storage Devices (Hard Drives & Floppy Drives)
Output Devices
•Monitor
•Printer
Components of a Computer System

11. Information
Processing Cycle
Input
Process
Output Storage
Communication
• Input--This is when information is
entered into a computer. It first
accepts data such as raw facts, figures,
and symbol
• Processing--Processes data into
information (Data that is organized,
meaningful, and useful) by the
computer’s brain -CPU
• Output--This is the information that
comes out of a computer after it has
been processed. It produces and
stores results

12. Why Is a Computer So Powerful?
 Speed
 Reliability
 Accuracy
 Storage
 Versatility
 Communications
