Speaking 2: Hardware
A guide to the components inside my computer .Hello and welcome
to videojug we're going to show you what the major components inside your
computer are and tell you a little about what each of them do guiding us on
this tour will be Phil Borton of East a technology support in brighton.
Step 1: The major
components the major components of a computer are the motherboard the cpu or
central processing unit ram or the random access memory the graphics card the
power supply the hard disk or hard drive the optical drive also known as a CD
or DVD drive.
Step 2: hardware and
software all of these components are usually found within the Tower of a
desktop computer they are referred to as hardware hardware can be thought of as
the actual physical components that go into the computer software refers to the
programs and systems that operate within the hardware.
Step 3: The motherboard the motherboard is the heart of the
computer it is the largest and most fundamental component of a pc and every
other component is attached to it in some way this is because all the different
components used the mother board to communicate and work with each other the
motherboard has a series of slots sockets and connectors for attaching the
components of a pc in most cases the memory accessory cards and cpu are
installed directly onto the motherboard the drives and peripherals communicate
with the motherboard through wired connections there are a wide range of
motherboards to choose from they different features speed capacity and the cpu supported
they also different size shape and layout this is commonly referred to as the
form factor.
Step4: For the cpucpu
stands for central processing unit this is the brain of the computer and is
often referred to as the processor or the chip it is found under a heatsink and
fan and sits directly on the motherboard the cpu directs coordinates and
communicates with the other components and performs all of the thinking it is
not really thinking what a cpu actually does it perform mathematical
calculations it is the software that people write that translates these
calculations into useful functions for us.
Step 5: Ram ram stands
for random access memory and comes as modules and predefined amounts it is also
found directly on the motherboard and usually in one two or four slots the
memory chip store information temporarily for short term used by the cpu ram is
used to store information for files that are actually being used by the cpu at
any given time the computer's ram memory is an entirely different thing from
the hard disk memory the hard this stores information permanently for long-term
use.
Step 6:The graphics
card the graphics card or video card translates information into the graphics
and tax that appear on the monitor screen most motherboards now include a slot
specifically designed for the graphics adapter called the AGP slot this stands
for advanced graphics port modern graphics adapters usually incorporate some
memory write on the card to improve their performance.
Step 7 : The power
supply this supplies power to the other components which is why it has so many
wires coming out of it is usually positioned at the back top corner of the
computer case the power supply has a fan built into it to keep itself and the
computer cool.
Step 8: The hard disk
a hard disk which is also called a hard drive is much like a filing cabinet the
programs and data is stored on the hard disk and the computer accesses them as
they are needed when the computer accesses the hard drive it is reading and
moving the stored information into the ram memory that memory is the temporary
workspace however the original file is still on the hard disk and has left
undisturbed until the file is saved when the computer stores or saves
information it writes a data to the hard disk that process results in the old
file being replaced or modified with the new information if you save data to a
new file or install new software the information is written to the disc in an
available unused portion of the disk.
Step 9: the optical
drive the optical drive is often called a DVD drive or a CD drive it sits at
the front of the computer for ease of access and use a laser to read and write
information to CDs and DVDs done.
