Reading Practice TEXT 5B THE MOTHERBOARD 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 (e.g. 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 CD-ROM or DVD drive that is used for reading CD-ROM or DVD drive 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. 44.
