BASIC COMPUTER PARTS
• CPU
• RAM
• HARD DISK DRIVE
• VIDEO CARD
• MOTHERBOARD
• POWER SUPPLY
• MONITOR
• SPEAKER
• KEYBOARD
• MOUSE
• AVR
CPU
• CPU (central processing unit) is “the brains” of a computer.
Jeremy Laird, an avid tech journalist, says that the CPU’s
“function is to select instructions, process them, perform
arithmetic and logical comparisons, and store results of
operations in memory,”
RAM
• RAM (random access memory) RAM is your system's short-term
memory. Whenever your computer performs calculations, it
temporarily stores the data in the RAM until it is needed. This
short-term memory disappears when the computer is turned off.
HARD DISK DRIVE
• It is known as permanent memory and is not volatile, meaning it
does not get erased when the power is shut off. This type of
memory is where all your documents, pictures, programs, videos
and movies are stored and kept safely.
VIDEO CARD
• The Graphics processing unit (GPU) often referred to as a
graphics card is used primarily for 3D applications. This is the
equivalent to how your eyes function and relate your beautiful
visual sensory details to your brain. These calculations are
extremely mathematically intensive tasks that would put fair
amount of strain on the CPU. By allowing the GPU to take over
these tasks it enable the CPU to tend to other non-visual related
calculations that the computer needs to function.
MOTHERBOARD
• Motherboards, often referred to as a logic board, main board or
“mobo” for short, are the “back-bone” of the computer. Its
purpose is to connect all the parts of the computer together and
make everything centralized using its printed circuit board.
POWER SUPPLY
• Power supply is in charge of bringing electrical power to the
computer. The PSU helps convert AC (alternating currents) from
your home to the DC (direct current) needed to power your
computer components.
MONITOR
• The main function of a computer monitor is to display video and
graphical information generated by the computers graphics
adapter, allowing the user to interact with the computer. It is
categorized as an output device.
SPEAKER
• Computer speaker is the other output device which is used to
hear a sound played by a computer. Speakers can be built in
with the motherboard or comes as a separate part. It connects
with the computer speaker with a cable.
KEYBOARD
• A computer keyboard allows an operator to give commands to
the computer in a simple way by pressing keys. The keys on a
keyboard are typically labeled with their input function, ranging
from letters of the alphabet to numbers and symbols.
MOUSE
• A computer mouse is a pointing device (hand control) that
detects two-dimensional motion relative to a surface. This
motion is typically translated into the motion of a pointer on a
display, which allows a smooth control of the graphical user
interface.
AVR
• An Automatic Voltage Regulator is an electronic device or circuit
that maintains an output voltage to be consistent to its load
current. This is necessary because the voltage delivered to your
home and mine may sometimes fluctuate which can cause
serious damages to your appliance; if not completely destroying
it. Fluctuations in power are brought about by so many factors.
