 Most of us will have some experience of Microcomputers or Personal Computers, they are found in homes and offices all around the world. \\
-Shown on the right is one of the earliest Personal Computers made by IBM for use in offices. The earliest computers were very slow by comparison with todays computers, but at the time they were a big step forward because they made it possible to write and print letters faster and more easily than on a typewriter, and were able to process numbers and sums with a program called a "Spreadsheet". This made it possible for financial calculations to be carried out faster and on a larger scale than was possible with manual accounting.

This made it possible for financial calculations to be carried out faster and on a larger scale than was possible with manual accounting. Later "presentation" software arrived.
 Most of this article will be about Microcomputers because you will have the best opportunity to work with them.

 Because they are portable, a laptop power supply is amost always external to the case, but a battery is included so the laptop can be run away from any mains electricity.
-Also a laptop will often include wireless ethernet connectivity, also known as WiFi. On more recent models, 3g wireless is included for use when away from home or the office.

 When laptops were first introduced, they were much slower than their desktop equivalents, but current models offer almost the same performance.
