2 like a person, acomputer is composed of two parts: the bone handware and the soul-software . let us get closer to the computer from the basic components.
3 the basic building block of a modern is a chip, a complex integrated electronic cicuit on a tiny square of silicon no bigger than a fingernail.
4 let us use the system shown in pic2.3 to show you how a typical computer works. a computer is controlled by a stored program. so if we want to use a computer, the first step is copying the program from diskette in to memory. now the processor can begin executing instructions; the date input from the keyboard are stored in memory, the processor processes the date and then stores the results back into memory. At last, we can get the result.
5 the processor, usually called the central processing unit(CPU) or main processor is the heart of a computer, it is the cpu that in fact processes or mani pulates date and controls all the rest parts of the computer.
6 we usually diride the storage derices in to two types: then main memory and the secondary .a cpu can only execute the instructions of a program which has already been in the main memory.
7 just as aperson has a lot of ideas, there are several kinds of software each of which does different jobs, at first, we will give you a short introduction to the application software.
8 the difference between a computer virus and other programes is that viruses are designed to self-replicate(that is to say, make copies of themselves.
9 another type of software, called system software, performs its as-signed tasks behind the scenes.
10 a platform refers to the type of operating system used by a computer, such as Windows or UNLX.
11 requirements analysis is the process of understanding the customers needs, and capturing them in a formal document.
12 internet is a giant global and open computer network, which is a collection of interconnected networks, it is also a way to realize world wilde in for mation exchanging and resource sharing between international computers.
