Any device added to a computer that performs an additional feature, but is not required. A good example of an accessory is the computer printer, which gives the computer the ability to print, but thecomputer would still work if it didn’t have the printer. Below, is a listing of computer accessories.

Types of Computers

Before looking at the various components, it is useful to distinguish between two different types of computers: desktop computers and laptop computers. A desktop computer consists of a computer case and a separate monitor, keyboard, and mouse. As the name suggests, this type of computer is typically placed on a desk and is not very portable.

Hardware Components

Let’s start with the computer case. This is the metal enclosure that contains many of the other hardware components. It comes in various shapes and sizes, but a typical tower model is between 15-25 inches high. Want to know what’s inside? Okay, go get a screwdriver and let’s open it up. Seriously, if you are really into computers, the best way to learn is to actually get hands-on. To save us some time, however, have a look at this desktop computer case. A computer enthusiast replaced the metal side panel with a transparent one, so we can have a look inside.

Although that photo looks pretty cool, it is a bit hard to recognize the individual components, especially with all the connecting wires running through it. This figure shows a more schematic version of a desktop computer, which makes it easier to point out the essential hardware components.

Types of Computer Accessories are Mouse, Keyboard, Wireless Router, Pen Drive, Card Reader, CD, DVD, Head Phones, Speakers, Webcam, Hard Drive, UPS, AntiVirus etc
