What are the parts of a computer?

A computer is really a system of many parts working together. The system unit is the core of a computer system. Inside this box are many electronic components that process information. The most important of these components is the central processing unit, called the CPU, or microprocessor. It acts as the ‘brain’ of your computer. Another component is random access memory or RAM, which temporarily stores information that the CPU uses, while the computer is on.

                           Your computer is also has a mouse which is a small device used to point to, and select item on your computer screen. A keyboard is used mainly for typing text into your computer, then there is a monitor which displays information in visual form, using text and graphics.

To connect your computer to the internet, you need a modem. A modem is a device that sends and receives computer information over a telephone line, or high-speed cable.

First hidden sight

A webcam is essentially just a camera that is connected to a computer, either directly or by wireless.

In 1991, the first webcam was set up at Cambridge University. Its sole purpose was to monitor a particular coffee marker so as to avoid wasted trips to an empty pot.

The first message

 Do you know what the first message on the internet was? It was ‘LOG’. The user was trying to type the word ‘log in’ , but the network crashed after the first word! It was sent by Leonard Kleinrock on Oct. 29^th, 1969.
