PARTS OF THE COMPUTER

Random access memory(RAM): it takes the form of integrated circuits that allow stored data to be
accessed in
any order

Read only memory(ROM): it is mainly used to distribute firmware (software that is
very closely tied to specific hardware, and unlikely to need frequent
updates).

Central processing unit (CPU): is the portion of a computer system that carries out
the instructions of a computer program, and is the primary element carrying out the
computer's functions.

Mother board: in personal computers, a motherboard is the central printed circuit
board (PCB) in many modern computers and holds many of the crucial components
of the system, while providing connectors for other peripherals.

Key Board: which uses an arrangement of buttons or keys, to act as mechanical
levers or electronic switches.

Mouse: a *mouse *is a pointing device that functions by detecting two-
dimensional motion relative to its supporting surface.

Display Monitor: monitor or display (sometimes called a visual display unit) is
an electronic visual display for computers. The monitor comprises the display
device, circuitry, and an enclosure.

Disk Drive: A hard disk drive
 (HDD) is a non-volatile, random access device for
digital data. It features rotating rigid platters on a motor-driven spindle within a
protective enclosure. Data is magnetically read from and written to the platter
by read/write heads that float on a film of air above the platters


 Printer: In computing, a printer is a peripheral which produces a text and/or graphics
of documents stored in electronic form, usually on physical print media such as paper
or transparencies.


Digital Camera: A digital camera (or digicam) is a camera that takes video or
still photographs, or both, digitally by recording images via an electronic image
sensor.


Scanner: In computing, an image scanner—often abbreviated to just scanner— is a
device that optically scans images, printed text,handwriting, or an object, and
converts it to a digital image.


Modem: A modem (modulator-demodulator) is a device that modulates an analog
carrier signal to encode digital information, and also demodulates such a carrier
signal to decode the transmitted information.


WiFi: Wi-Fi: (pronounced /ˈwaɪfaɪ/) is a trademark of the Wi-Fi Alliance. A Wi-Fi
enabled device such as a personal computer, video game console, smartphone
or digital audio player can connect to the Internet when within range of a wireless
network connected to the Internet.
