Historical evaluation of computer

  1. 1. Welcome to Presentation
  2. 2. Historical Evaluation of Computer
  3. 3. Functions of Computer Characteristics and Limitations Of Computer Generations Of Computer Classification Of Computer Computer System and Technology Software Operating System Computer Language
  4. 4. Computer “The computer was born to solve problems that did not exist before.”
  5. 5. Functions Of Computer Accept Data Process Data Output Data
  6. 6. Characteristics Of Computer Faster Accurate Various Performance Diligence Reliability Vast Memory
  7. 7. Limitations Of Computer Costly Dependent Need of an expert programmer Non Standardization Artificial
  8. 8. Various Generations of Computer First generation computer(1951-1959): Use of vacuum tubes Second generation computer(1959-1965): Use of transistors Third generation computer(1965-1971): Use of IC Forth Generation computer(1971-Current year): Use of large scale of Integration Fifth Generation computer(future Generation): Use of ULSI
  9. 9. Digital Computer Classification of Computers Micro computer Mini computer Mainframe Computer Super computer
  10. 10. Relationship Between System and Technology Technology: Composed of hardware, software, data and telecommunication System: Group of interrelated components Input Processing Output Feed back: Data about the performance of a system Control: Monitoring and evaluating feedback
  11. 11. Components of Computer system Hardware Software User Data
  12. 12. Major Types of Software
  13. 13. Operating System An integrated set of programs that acts as a basic platform for the hardware applications programs to run.
  14. 14. Functions of operating system
  15. 15. Classification of Operating System : Batch/Off line Mode Operating System Multiprocessing Operating System
  16. 16. Multitasking Operating System Time sharing operating system
  17. 17. Distributed operating system
  18. 18. Real time Operating System Virtual storage operating system
  19. 19. Computer Language Language Low level Language 1. Machine language 2. Assemble language High level language
  20. 20. Low Level Language Easily Understandable for Computer Execute Fast Machine Dependent Inefficient in error finding Hard for logic development Machine language: Directly executed without any translation. Instruction written in what can understand by processor. Assemble language: Instructions are written in codes and symbolic address.
  21. 21. High Level Language Human understand easily Slow in execution Slow in execution Easy in error finding Easy in developing logic
  22. 22. Thank You
