Computer fundamentals 1

  1. 1. BASICCOMPUTERCONCEPTS
  2. 2. COMPUTERAn electronic system that can beprogrammed to accept, store andmanipulate/process data to come out withmeaningful output referred to asinformationIt carries out its task/s through a set ofinstructions called a computer program.
  3. 3. Capabilities of Computer Processing of Repetitive, High Volume Applications Self-Operation Decision Making
  4. 4. Limitations of Computer Failure to derive meaning from objects Inability to generate information on its own Failure to correct wrong answer
  5. 5. Classification by Size  NOTEBOOK/LAPT OP  DESKTOP/ PC  MINICOMPUTER  MAINFRAME  NETWORK
  6. 6. Components of Computer System PEOPLEWARE Managers System Analyst/Designer Programmers Operators/Technicians Users SOFTWARE System Software Application Software HARD WARE
  7. 7. HARDWAREThisrefers to thephysical equipment thatmake up a computersystem
  8. 8. HARDWARE COMPONENTS SYSTEM UNIT Microprocessor Memory Read-Only Memory(ROM) Random Access Memory (RAM) INPUT DEVICES STORAGE DEVICES OUTPUT DEVICES
  9. 9. SYSTEM UNIT
  10. 10. MOTHERBOARD
  11. 11. Central Processing Unit This is the “BRAIN” of a Computer System It is the device that fetches, decodes and executes instructions Transfers data between the memory and other peripheral devices through data bus For Personal/ Micro Computers, this is referred to as the Micro Chip
  12. 12. MEMORY
  13. 13. INPUTInput device is a unit that is used to get data from the user into the central processing unit.
  14. 14. INPUTKeyboard andMouse
  15. 15. INPUTCard Reader Barcode Reader
  16. 16. STORAGE Data instructions enter main storage and are held until needed to be worked on. Itcan be an auxiliary or backing storage.
  17. 17. STORAGEDiskette Magnetic Tape
  18. 18. STORAGEUniversal Serial Bus CDs/DVDs Sticks
  19. 19. STORAGE Hard Disk
  20. 20. OUTPUT Resultsare taken from main storage and fed to an output device. Shows people the processed data- information in a ready-to-use form.
  21. 21. OUTPUT MONITOR
  22. 22. OUTPUT Printer
  23. 23. SOFTWARE Set of programs, procedures, routines anddocuments associated with the operation ofa computer system. Software is the name given to the programthat causes a computer to carry outparticular operations
  24. 24. Types of Software Programming Languages - medium used by humans to communicate instructions to a computer. Systems Software - collection of programs which contribute to the control and performance of the computer Application Software - programs designed to perform specific jobs such as spreadsheets, wordprocessors, graphic softwares system
  25. 25. PEOPLEWAREThe most importantcomponent ofcomputer system –people use the powerof the computer forsome purpose.
