The following part is for those who haven't got any experience with programming. So if you are not one of these, skip over to the next section.

First of all you should become familiar with some terminology: A program is a sequence of instructions, in this case instructions which you will write in Pascal. Executing (running) a program : carrying out the instructions. A process is a running program. Components of a Computer : Main Memory : Think of it as an ordered sequence of memory locations where you can store/retrieve data, volatile. CPU : The "Central Processing Unit", coordinates all activities by determining operations to be carried out. I/O Devices : I/O stands for Input/Output. eg. Keyboard, Mouse. Secondary Storage : Stores data externally permanently. Main Memory versus Secondary Storage : MM is faster, but volatile and more expensive, whereas secondary storage is permanent.
