Terminology for Computer Hardware
Unlike other electronic
devices, computer is the sum of its parts. Nobody cares
about the specifications and make of the picture tube of a
particular brand of television. But in the case of
computers, more than the brand name the specifications of
its components like processor, motherboard, RAM, hard disk,
and suchlike are the things that a knowledgeable consumer
first asks about. Here is computer hardware terminology in a
nutshell.
Processor or microprocessor is a powerful IC chip on which a
number of functions are incorporated. It is the heart and
brain of the computer rolled into a chip. Its efficiency
depends on its speed of processing, which is specified by
its frequency and it is denoted using gigahertz. The higher
the speed, the better will be its functioning. Also, there
are several types of processors such as 32-bit processor and
64-bit processor. The bit rate is not actually a yardstick
of speed. The larger bit rate means the processor will be
able to efficiently do several computing processes at the
same time.
Another main item in computer hardware terminology is
motherboard. In simple terms, it is the platform on which
all the other components are electrically fitted in. Over
the years, a number of additional functionalities such as
sound card, graphics card, and networking card are slotted
on to the motherboard. When selecting motherboard, one
should make sure that the motherboard is compatible with
other components such as processor, hard disk, and RAM.
Hard disk and RAM are the next items in the hierarchy of
computer hardware terminology. A computer has two types of
memory. Permanent memory is stored magnetically on hard disk
and it will be stored in the disk even after the computer is
shut down. On the other hand, RAM or random access memory
will be off once the computer is shut down. It is the kind
of memory on which the functional information while running
a computer, like running programs and unsaved data, are kept
when computer is running. When you save a file, the data is
stored to hard disk from RAM.
Nowadays the memory capacity of hard disk is skyrocketing.
It is all set to break the upper limits of gigabytes.
Comparing to that, RAM was a slow starter. It is still
ambling along the lower middle part of gigabytes. Lay users
do not need a RAM with a large capacity. The price of RAM
increases with the rise in memory capacity.
Computer peripherals like keyboard, mouse, monitor, CD or
DVD drives and writers, speaker, and webcams are all part of
a large list called computer hardware terminology. There are
other hardware items also such as graphics card, sound card
and video card for sound recording and video editing
facility, and internal and external modems for browsing the
internet. |
