Correct the teacher!

Your teacher has written some notes to help you. Unfortunately, he wrote them very quickly. In addition, he never checked them. There are a lot of mistakes in the notes. Your job is to find as many of them as you can and then correct them.

Hardware is anything you can touch. A good example would be PowerPoint. Software is the name we give to programs (sets of instructions) that make the hardware do useful things. Microsoft Office is a good example of hardware. The brain of the computer is known as the CPU (Central Peripheral Unit). It gets information from the outside world from output devices (such as the keyboard), processes the information and then sends it out to the input devices (usually to the monitor or speakers) so we can see the results. The programs that the computer uses to process the information is held in the RAM, short for Read Access Memory. These programs in RAM disappear when you switch the power on. You therefore need to store all programs using a storage device, such as a pen drive or a softdrive. Another type of memory is called ROM (Read Once Memory). ROM contains a program which checks your computer is working properly when you switch it on. Then the program in ROM copies the operating system from the RAM into the hard drive so that the operating system can take control of the computer. 

There are a few other words you might come across. These include 'peripheral', 'motherboard', 'network card' and 'port'. A peripheral is any piece of hardware that you can attach to your computer. A motherboard is a special board that lets you connect up all of the components inside a computer. A network card is a special card that you connect to the motherboard, to allow you to connect the computer to a network, and a port is something that ships sail in to.
