What are Computers?A computer is a machine that carries out instructions given to it by a human. Without instructions, computers wouldn’t be able to do anything.
What makes them special?
• work faster than humans• are more accurate than humans• can store huge amounts of information that they never “forget”
Some other important things to remember:
• Computers don’t have brains; they are not cleverer than humans
• Computers don’t have feelings or “common sense”

Types of ComputersComputers come in many shapes and sizes. Computers that most people might recognise include:
• Desktops• Laptops• Tablets• Smart phones• Mainframes• Servers• Games Consoles• Embedded computers
Rapid advancements in technology has meant that computers have become much more powerful, much smaller and much cheaper than ever before.

IPOA computer is a machine that:
• takes in information• stores this information• processes this information• and gives this processed information back out.
This can be represented as:
This is known as the Input, Process, OutputDiagram (or IPO) for short.
