What is a Computer?
A computer is an electronic machine used to process information. However, we can do a whole lot more with computers than just calculate numbers or print out data. We can draw pictures, write memos and reports, and even communicate with other computer users. Educators can use the computer to write lesson plans, notices, letters, make visual aids, create presentations and share and collaborate with other teachers from around Uganda and the world.

There are two basic parts of a computer: hardware and software.
Hardware is a generic term for all the physical components of the computer.
Software is a generic term for the programs that run on a computer.

Hardware is another term for the physical components of a computer. This is the most basic level on which the computer operates. The key point to remember is that all information is processed electronically. PC stands for Personal Computer, although that abbreviation is most often associated with computer running the Windows operating system. Below is a picture of a standard PC with each hardware part labeled. The photo on the right shows how the monitor, keyboard and mouse are connected to the System Unit.
