14. COMPUTER HARDWARE

Task 1: Describe the picture and the functions of hardware.

Modem - is short for "Modulator-Demodulator." It is a
hardware component that allows a computer or another device, such as a router or switch, to
connect to the Internet. It converts or "modulates" an analog signal from a telephone or cable wire to digital data (1s and 0s) that a computer can recognize.


Power supply unit -(PSU) converts mains AC to low-voltage regulated
DC power for the internal components of a computer. Modern personal computers universally use switched-mode power supplies. Some power supplies have a manual switch for selecting input voltage, while others automatically adapt to the mains voltage.


Graphics, Sound and Network cards A sound card is an expansion card or IC for producing sound on a computer that can be heard through speakers or headphones. Although the computer doesn't need a sound card, it's included on every machine as either in an expansion slot (shown below) or built into the motherboard (onboard).
Back USB connectors There is technically no difference between the front and rear USB
ports. The rear ports are soldered to the motherboard and the front port have a cable which
connects them to the mother board. The Front or rear ports can be used to easily access devices
kept in front or back.


RAM stands for random-access memory, but what does that mean? Your computer RAM is essentially short term memory where data is stored as the processor needs it. This isn't to be confused with long-term data that's stored on your hard drive, which stays there even when your computer is turned off.
Router A router is a device that connects two or more packet-switched networks or subnetworks. It serves two primary functions: managing traffic between these networks by forwarding data packets to their intended IP addresses, and allowing multiple devices to use the same Internet connection.
CPU central processing unit (CPU), principal part of any digital
computer system, generally composed of the main memory, control unit, and arithmetic-logic unit.
Mother board is the main printed circuit board (PCB) in a
computer. The motherboard is a computer's central communications backbone connectivity point, through which all components and external peripherals connect.
