  1. Computer Parts • There are many parts that work together to make a computer work. Hardware

  2. Hardware • Physical parts of the computer, including processor and memory chips, input/output devices, tapes, disks, modems, cable, etc.

  3. CPU • The Central Processing Unit • The “Brain” • One of the most expensive

  4. Processor • The CPU – The chip or chips that interpret and execute program instructions and manage the functions of input, output, and storage devices.

  5. Motherboard • The motherboard connects all the other components to one another, and is the physical base upon which you build everything else.

  6. RAM • Random Access Memory • RAM is a computer’s temporary memory, which exists as chips on the motherboard near the CPU. It stores data or programs while they are being used and requires power.  Short-Term Memory

  7. ROM • Read Only Memory • Data stored in ROM cannot be modified, or can be modified only slowly or with difficulty • ROM chips are used not only in computers, but in most other electronic items as well.

  8. Computer Case • Contains the major components of the computer. It helps protect them.

  9. Inside the Computer Case

  10. Peripheal Devices • A peripheral is a piece of computer hardware that is added to a computer in order to expand its abilities. There are all different kinds of peripherals you can add your computer. The main distinction among peripherals is the way they are connected to your computer.  Internal or External  Input or Output

  11. Monitor • A display screen to provide “output” to the user. It is where you view the information your are working on.

  13. Keyboard • Used to enter information into the computer and for giving commands.

  14. Mouse • An input device operated by moving the object across a flat surface. The mouse is used to control the on-screen pointer by pointing and clicking, double-clicking, or dragging objects on the screen.

  15. Touchpad • A pressure-sensitive and motion sensitive device used in place of a mouse.

  16. Barcode Reader • An input device that converts a pattern of printed bars into a number that a computer can read. They are often used by businesses to quickly input price and product information.

  17. CD Rom Drive • The drive that plays CDs and reads data that has been stored on the CD.

  18. CD • Compact Disk – A type of optical storage device.

  19. USB Flash Drive • USB flash drives are small, fast, removable, rewritable, and long-lasting. Storage capacities range from 64MB to 32GB or more.

  20. Hard Disk • Magnetic storage device in the computer.

  21. Printer • An output device that produces a hard copy on paper. It gives information to the user in printed form.

  22. Scanner • A device that allows pictures to be placed into a computer.

  23. Microphone • Allows the user to record sounds as input to their computer.

  24. Speakers • Used to generate or reproduce voice, music, and other sounds.

  25. Sound Card • Connects the speakers and microphone to the computer.

  26. Video Card • Connects the computer to the monitor. It is a circuit board attached to the motherboard that contains the memory and other circuitry necessary to send information to the monitor for display on screen.

  27. Modem • The place where the computer is connected to the phone line.

  28. Network Card • A circuit board that connects the computer to the rest of the network usually using special cables.

  29. Software • Programs that tell the computer what to do. It provides instructions that the CPU will need to carry out.

  30. DOS • Disk Operating System This software connects the hardware with the programs you want to run. MS-DOS: Microsoft DOS (Disk Operating System) is a command line user interface. MS-DOS 1.0 was released in 1981 for IBM computers.

  31. Example of MS-DOS

  32. Operating Systems • The operating system is the most important program that runs on a computer. Every general-purpose computer must have an operating system to run other programs. Operating systems perform basic tasks, such as recognizing input from the keyboard, sending output to the display screen, keeping track of files and directories on the disk, and controlling peripheral devices such as disk drives and printers.
