Input, output and storage devices on a computer

A computer is a programmable device that stores and manipulates information.  It receives, processes and store information.  In fact, there are input, output and storage devices on a computer as listed below:-

  1. Input devices

Input devices are the electronic components of a computer that work by producing signals while entering data. Examples include;

  • Keyboard
  • Scanners
  • Microphone
  • Web cam
  • Mouse
  • Touch screen
  • Barcode reader


  1. Output computer devices

According to Parsons  & Oja (2011), an output device in a computer refers to any hardware that has the ability to deliver or show information in different forms to diverse users.  As a matter of fact, output computer devices display, print and present the processed results of computer processing’s.  Computer output devices include:

  • Monitor
  • Printer
  • Speaker
  • Storage devices

Computer storage devices store and protect the information processed by computers from loss.  These devices include:

  • Floppy disks
  • USB Flash drive
  • DVDs
  • CDs
  • Memory Cards

In computer technology field, a microprocessor is a silicon chip that contains the Central Processing Unit (CPU). They control the logics of almost all the computerized devices.  Essentially, a microprocessor is a term that is used interchangeably with CPU and it operates as the brain of all devices in which it operates (Mathivanan, 2003).

Apart from computers, there are other devices that operate through the control of microprocessors. They include; Watches, cell phones, metal detectors and pedometers among many other devices. In the present world, numerous household devices will have been devised with the incorporation of “microprocessors” inside. They include washing machines, microwave ovens, stoves and driers among others.  This will be an endeavor to quicken and ease the process of operation as well as augmenting the levels of reliability. In my professional organization will be of great value as they will set a strong foundation for the start of my career in technology and further nurture my strengths to the required levels.  Briefly, professional organizations will provide employment opportunities.
