The document presents an overview of computer systems, defining a computer as an electronic device that processes data and provides output. It categorizes computers into various types like palmtops and laptops, and details the components of a computer system, which include hardware and software. Additionally, it highlights the roles of input, processing, and output units, along with categorizing software into application, system, and utility types.
![WE CAN CATEGORIZE HARDWARE COMPONENTS IN THREE BROAD
CATEGORIES:

- 2. Types And Components of Computer System presented by; M.SOHAIL ASGHAR 2
- 3. INTRODUCTION TO COMPUTER THE TERM COMPUTER IS USED FOR ANY DEVICE THAT MAY BE EMPLOYED TO COMPUTE OR TO CALCULATE. presented by; M.SOHAIL ASGHAR 3
- 4. WHAT IS COMPUTER? • A COMPUTER IS AN ELECTRONIC DEVICE THAT RECEIVES INPUT, STORES IT FOR A PERIOD OF TIME, OPERATING IT ACCORDING TO A SET OF INSTRUCTIONS AND GIVES THE USER WITH AN OUTPUT. -OR- • COMPUTER IS AN ELECTRONIC DEVICE WHICH CONVERTS DATA INTO INFORMATION. presented by; M.SOHAIL ASGHAR 4
- 5. • COMPUTERS COME IN ALL SORTS OF SHAPES AND SIZES. BASED ON CAPACITY, SPEED AND RELIABILITY COMPUTERS CAN BE DIVIDED INTO THE FOLLOWING CATEGORIES OF COMPUTERS: • A PALMTOP COMPUTER IS SIMILAR TO A LAPTOP COMPUTER, BUT SMALLER. ITS SMALL ENOUGH TO FIT IN THE PALM OF YOUR HAND. PALMTOPS ARE USUALLY NOT VERY POWERFUL SINCE CPUS REQUIRES A LARGE BATTERY AND GET HOT – BOTH PROBLEMS IN SMALL DEVICE. presented by; M.SOHAIL ASGHAR 5
- 6. • A LAPTOP COMPUTER IS A LIGHT, COMPACT AND PORTABLE PC. LAPTOPS CONTAIN A RECHARGEABLE BATTERY SO THAT THEY CAN BE USED EVEN WHEN NOT PLUGGED IN TO A MAINS POWER SUPPLY. THEY ALSO BUILT-IN LCD MONITORS. presented by; M.SOHAIL ASGHAR 6
- 7. • A COMPUTER SYSTEM IS THE COMBINATION OF HARDWARE AND SOFTWARE. A TYPICAL COMPUTER SYSTEM HAS MEMORY AND SET OF STATES THAT DEFINES THE RELATIONSHIP BETWEEN THE SYSTEMS INPUTS AND OUTPUTS. presented by; M.SOHAIL ASGHAR 7
- 8. Speed Accuracy Storage Versatility Automation presented by; M.SOHAIL ASGHAR 8
- 9. INPUT PROCESS OUTPUT presented by; M.SOHAIL ASGHAR 9 Input unit is used to enter data into computer Processing takes place in the processing unit. It has three main units- memory,CU,AL U. We get the output on the output unit.
- 10. THE COMPUTER SYSTEM HAS TWO MAIN COMPONENTS WHICH WHEN BOTH COMBINED MAKES A COMPUTER SYSTEM. THESE ARE 1) presented by; M.SOHAIL ASGHAR 10
- 11. presented by; M.SOHAIL ASGHAR 11
- 12. SOFTWARE IS A GENERAL TERM USED TO DESCRIBE A COLLECTION OF A COMPUTER PROGRAMS, PROCEDURES AND DOCUMENTATION THAT PERFORM SOME TASKS ON COMPUTER SYSTEM. SOFTWARE INCLUDES WEBSITES, PROGRAM, VIDEO GAMES ETC. presented by; M.SOHAIL ASGHAR 12
