1.1. Computer SystemsA typical single-user computer system is built out of many parts, including a central processing unit (CPU), memory, disks, a monitor, and a keyboard. Small systems like this may be connected together to form larger computer networks, enabling tasks to be distributed among individual computers. Figure 1-1 is an illustration of such a network. Figure 1-1. A typical computer network.The hardware that goes to make up a computer network is only half the story; the software that runs on the computer is equally important. Let's take a closer look at the various hardware and software components of a computer system. |
