The main circuit board inside your system is called the motherboard and contains processor, the memory chips, expansions slots, and controllers for peripherals, connected by buses.

Слайд 11

Ports for peripherals On the rear panel of the computer there are several ports into which we can plug a wide range of peripherals – a modem, a digital camera, a scanner, etc.

Слайд 12

Peripherals include storage devices and input/output devices. F.e. Disk drives are storage devices. They are used to read and write data on disks.

Слайд 13

Input devices enable data to go into the computer’s memory. The most common input devices are the mouse and the keyboard. Output devices enable us to extract the finished product from the system. F.e the computer shows the output on the monitor or prints the result by means of a printer.
