Hi Folks,
Not much stuff in the newsletters this past week but I found a few you might be interested in. The forth one down is for those of you who are using IE7 and aren't happy with the new look. The last item is just for imformation - a lot of people tend to get the terms mixed up and when I saw this one, I thought some of you might find it useful.

Computer
Components For Idiots
There are many fancy
add-ons for computers, but the basic components of the computer are simple
and universal. If one of these main components is missing, it’s not a
computer.
The four essentials of
every computer system are: a motherboard, a Central Processing Unit (CPU),
memory, and a hard drive. These components are installed in a case, which
is attached to a monitor, a keyboard, and a mouse. That’s your basic
computer.
Mother
WHAT?
The motherboard
(“mobo“ for short) is the foundation. Everything attaches to the mobo -
the CPU, memory, hard drive, monitor, mouse, keyboard, add-on cards, even
additional peripherals like printers, scanners, and speakers. The
motherboard is like the nervous system and skeleton of the human body - it
provides support for the internal components and also passes information
between the computer parts.
CPU
If the motherboard
is the nervous system, then the CPU is the brain. Most of the mathematical
manipulations that make computers operate are done by the CPU. Other
components may also have their own processors, but their results still
have to be passed through the CPU.
The speed of the
computer is usually measured by the speed of the CPU. Even though other
factors also affect overall speed, the CPU rating is generally seen as the
single most important measure of performance.
Modern CPUs are
usually rated between 2.0 GHz and 3.0 GHz, although each passing month
will see increasing performance. This measurement refers to the number of
calculations the processor can make in one second. The higher the number,
the faster (better) the computer.
CPUs generate a lot of
heat doing this work, so they need a heat sink and fan to keep them from
overheating. Heat is a major enemy of the computer and directly affects
its life span.
Computer
Memory
RAM (Random Access
Memory) is the part of the computer that stores information the computer
needs while it is operating. It is Random Access because the computer can
get the data in any order, not necessarily the order in which it is
stored. Generally speaking, the more RAM, the better. 512 to 1024
megabytes is common for memory.
The most common type
of RAM these days is DDR-SDRAM, which stands for double-data-rate
synchronous dynamic random access memory. We already know what the RAM
part means. DDR means that the data is accessed twice as fast as ordinary
RAM.
The latest type of RAM
is DDR2. It offers even faster access rates and is quickly becoming the
standard for computer memory.
Hard
Drive
All the data
contained in RAM is lost when the computer is turned off, so there has to
be a place to store it permanently. This is what the hard disk is
for.
It holds the
computer’s operating system. An operating system like Windows uses around
four gigabytes of hard drive space. The extra space is used to install
computer programs and to store your personal data.
80 gigabyte hard
drives are common, but much larger are available. Furthermore, you can
install more than one in a computer case for added security and
convenience.
Peripherals
All you need to
complete the basic computer system is a monitor, keyboard, and
mouse.
Accessories like a
printer or scanner are useful for office work, and gamers will probably
want to add speakers and joystick controls.
So there you have it.
The basic computer needs just seven major components. For the best
performance, these components must integrate well. The motherboard is the
most important component for determining the type and specification of the
other parts. Choosing an appropriate mobo for your computer needs is the
first step and may require a quick call to your local
geek.
Soon, YOU will be
considered the local geek!
