Basic of Computer fundamental

  1. 1. Introduction to Computer Er. Sohan Grover IT-Trainer
  2. 2.  What is Computer ?
  3. 3.  Computer is an Electronic Machine that Receive the instruction to the Existing user and process it and finally give the output according to the user need.  Computer is an electronic device that process, stores and outputs data at high speeds.
  4. 4.  What is electronics machine???  What is electrical machine??? What is the difference between electronics and electrical machine????
  5. 5. Basic advantage of a computer 1. Speed 2. Multitask 3. Save time 4. Accuracy
  6. 6. Disadvantages of a Computer ?? 1. Decision 2. Validation 3. Maintenance 4. Misuse
  7. 7.  Components of computer???
  8. 8.  Hardware  The physical components of the computer which are located inside the cabinet.
  9. 9. Major Components of computer Hardware : 1. Input Devices 2. Output Devices 3. Processing Unit
  10. 10. An INPUT DEVICE lets you TALK TO the computer
  11. 11. An OUTPUT DEVICE lets the computer TALK TO you
  12. 12. The CPU (Central Processing Unit) is the brain of a computer – it tells the other parts what to do
  13. 13. The CPU Stand for the.. Central Processing Unit
  14. 14. ALU (Arithmetic & Logical Unit) MU (Memory Unit) CU Control Unit Parts of CPU
  15. 15. The RAM (Random Access Memory) is the temporary memory of a computer
  16. 16. The ROM (Read Only Memory) is the permanent memory of a computer
  17. 17. What is Computer Software? Software is the combination of different types of instruction that made for perform a specific task . Computer Software are programs that tell the computer what to do.
  18. 18. World first calculation machine World first calculation machine  The Abacus ( 1623 ) ◦ The first computing aid that were used to help them in their computation. (John Napier )
  19. 19. Pascal calculation machine (1642) Only (+,-)
  20. 20.  The Difference Engine ◦ An automatic, mechanical calculator designed to tabulate polynomial functions. ◦ By 1822 the English mathematician Charles Babbage who is considered as Father of the Computer today was proposing a steam driven calculating machine the size of a room
  21. 21.  Ada Agusta (first worlds programmer)  Embedded at Difference Engine  1890 America scientist Harman hollyrath  Create a machine those are used in america people calculation.  1939 atanasof and berry made first world electronic digital computer (ABC computer )
  22. 22.  1946 America scientist JP Eckert and John Markel Made world first computer ENIAC  1954 (General electronics corporation )UNIVAC
  23. 23. EVOLUTION OF COMPUTERS GENERATION 1 GENERATION 2 GENERATION 3 GENERATION 4 GENERATION 5
  24. 24. FIRST GENERATION COMPUTERS 1. Use of vacuum tubes 2. Big & Clumsy 3. High Electricity Consumption 4. Programming in Mechanical Language 5. Larger AC were needed 6. Lot of electricity failure occurred
  25. 25. SECOND GENERATION COMPUTERS 1. Transistors were used 2. Core Memory was developed 3. Faster than First Generation computers 4. First Operating System was developed 5. Programming was in Machine Language & Assembly Language 6. Magnetic tapes & discs were used 7. Computers became smaller in size than the First Generation computers 8. Computers consumed less heat & consumed less electricity
  26. 26. THIRD GENERATION COMPUTERS 1. Integrated circuits developed 2. Power consumption was low 3. SSI & MSI Technology was used 4. High level languages were used
  27. 27. FOURTH GENERATION COMPUTERS 1. LSI & VLSI Technology used 2. Development of Portable Computers 3. RAID Technology of data storage 4. Used in virtual reality, multimedia, simulation 5. Computers started in use for Data Communication 6. Different types of memories with very high accessing speed & storage capacity
  28. 28. FIFTH GENERATION COMPUTERS 1. Used in parallel processing 2. Uses superconductors 3. Used in speech recognition 4. Used in intelligent robots 5. Used in artificial intelligence
  29. 29. The future promises advanced technology in computing. Faster, smarter and more affordable.
