Details About Hardware

some picture

Hardware is a comprehensive term for all of the physical parts of a computer, as distinguished from the data it contains or operates on, and the software that provides instructions for the hardware to accomplish tasks. The boundary between hardware and software is slightly blurry - firmware is software that is "built-in" to the hardware, but such firmware is usually the province of computer programmers and computer engineers in any case and not an issue that computer users need to concern themselves with.

A typical computer (Personal Computer, PC) contains in a desktop or tower case the following parts:

  • Motherboard which holds the CPU, main memory and other parts, and has slots for expansion cards
  • power supply - a case that holds a transformer, voltage control and fan
  • storage controllers, of IDE, SCSI or other type, that control hard disk , floppy disk, CD-ROM and other drives; the controllers sit directly on the motherboard (on-board) or on expansion cards
  • graphics controller that produces the output for the monitor
  • the hard disk, floppy disk and other drives for mass storage
  • interface controllers (parallel, serial, USB, Firewire) to connect the computer to external peripheral devices such as printers or scanners

computer's hardware consists of the physical components necessary to operate and interact with a computer. Since a computer's primary language is binary, devices are necessary to convert our input into that language. The binary code coming out of the computer must also be translated into something usable for the operator

The CPU and Motherboard

  • The Central Processing Unit, or CPU, is the brains of the computer and the motherboard is the heart. The circuits on the motherboard control the flow of information from other devices to the CPU and back to the devices. To aid in this task, random access memory, or RAM, is integrated with the motherboard to temporarily store information that is being used.

Output Devices

  • Computers were invented to solve problems. Those answers would be useless if the operator had no way to see them or interpret them. Display terminals, or monitors, are the most common output devices. Printers are another output device that is common with current computer systems. While displays and printers let the operator see the data, speakers are used as an output device to let a user hear data from the computer as well.

Input Devices

  • A computer operator needs some way to put data into the computer. The keyboard and the mouse are the most common input devices, but other specialty devices are available. Microphones and web cams are input devices that are being used by more and more people to interact with others through their computers. Microphones are also used to help the visually disabled use computers more effectively. Some computer games also require a specific type of controller.


  • Every computer needs some kind of storage device to keep data and programs accessible. Hard drives are the most common storage device, but they have the disadvantage of being permanently mounted to the computer system. Portable storage devices are used to transfer stored data from one computer to another. Floppy disks were the early form of portable storage, but CD-ROMs and DVDs provide more data capacity than a floppy disk could. Flash drives are more portable and more difficult to damage than disks and are therefore one of the most preferred means of portable data storage.


  • As computer-based collaboration became more and more of a necessity, computers needed the ability to "talk" to each other. Modems were used to communicate with computers over long distances through the telephone lines and are still used by some people today. Newer modems are available to use digital signals through DSL or cable to communicate with other computers through the Internet. Wireless modems are available to transmit and receive data without the necessity of a phone line or cable.
