The main parts of a desktop computer are enclosed in a box known as the system unit. This contains an electronic board called the motherboard that holds and connects together the main electronic components. These are shown in the table below. The motherboard usually has empty electronic connectors, called expansion slots, into which additional electronic boards (sometimes called expansion cards) can be plugged. This allows extra electronic components to be added. For example, more memory can be added by plugging memory boards (called SIMMS) into the memory slots. Sound facilities can be added by plugging a sound card into an expansion slot. This is one way of upgrading a computer. Another way is to replace the motherboard with a newer and better one. The system unit usually also contains a small speaker (or loudspeaker), the power supply, and some storage devices. These often include: a hard disk drive with a fixed disk that can store a very large amount of data: a floppy disk drive that uses removable floppy disks (diskettes); a CDROM drive that is used for reading CD-ROM disks (particularly in multimedia computers). Some other devices may be included in the system unit but most input and output devices are plugged into the back of the system unit using connectors known as ports. Power is a function of both speed and capacity. The power of a computer depends on the combination of all the components. When buying a computer, you can often choose between different components. In particular, you can choose between different processor speeds, amounts of memory and hard disk sizes. Units of measurement commonly used in computing are shown below. Hertz are measured using the decimal system but bytes are measured using the binary system. The values of the unit prefixes vary in these two systems as shown in the table below. Задание 2.
