This PowerPoint presentation introduces the basic components and functions of a computer system. It describes that a computer system has four main parts: hardware, software, data, and users. It then defines each of these parts in more detail. Specifically, it explains that hardware refers to the physical and mechanical components of a computer, software refers to computer programs, data refers to pieces of information, and users are people who operate the computer. Finally, it outlines the basic information processing cycle that computers follow of input, processing, output, and storage.

logical operations or that assembles, stores,
correlates, or otherwise processes
information.

5. PARTS OF THE COMPUTER
Computer systems have four parts
 Hardware
 Software
 Data
 User

6. Hardware
 Mechanical devices in the computer
 Anything that can be touched
 CPU , Keyboard , mouse

7.  Data
 Pieces of information
 Computer organize and present data
 Users
 People operating the computer
 Most important part
 Tell the computer what to do

8. INFORMATION PROCESSING CYCLE
Steps followed to process data
 Input
 Processing
 Output
 Storage

9. ESSENTIAL COMPUTER HARDWARES
Hardware categorised into 4 types
 Processing devices
 Memory devices
 Input and output devices
 Storage devices
Software categorized into 2 types
 System software
 Application software

10. EDUCATIONAL IMPLICATIONS
The student is actively exploring phenomena ,instead
of being a passive recepient of information.
 Teacher and students can use computer –Based tools
such as, Text or Graphic editors, Databases,
Spreadsheets, or Presentation packages , to help in
processing information
