Computer mouse and
keyboard.
The mouse and keyboard of a
computer are important. If you fight with your
mouse pointer or don't like the feel of your
PC keyboard it may become very annoying. So
you have to get a good one but fancy stuff is
not better.
Older mouse used to have a
ball that would send the motions to the
computer through a serial port. They changed
this to a PS2 port so it would free the serial
ports for other slow devices. They also made
USB mice to make it easier for people to
connect it to the PC. The keyboard and mouse
connectors being both PS2 was sometimes
confusing and some could connect them in the
wrong connector.
The mouse using a ball were
getting dirty and had to be cleaned so they
would give smooth motions. Even if you used a
mouse pad, dust and other particles would
stick to the rollers in the mouse and would
eventually jam. They made IR or Infra Red mice
to get rid of this problem.
An Infra Red uses a light to
detect motions and will function on basically
any surface. This eliminates the need of a
mouse pad that is really annoying since it
limits the space you have to more. Some mouse
have 3 buttons but a 2 button mouse is usually
good enough. Most will come with a wheel to
scroll the display up and down without having
to use the scroller bar of the window.
Some mice are wireless and
will function with batteries to send the
signal to your computer. This is fun but has a
few down sides like the constant need to have
spare batteries to replace them when the mouse
stop functioning. So you have to constantly
pay to keep your mouse going or need to
purchase rechargeable batteries. I recommend
to use the wire mice.
Keyboards use to have their
own AT connector but was replaced by the PS2
smaller connectors on the new computers. They
also have USB keyboards that will work just
the same as the PS2 type. Some keyboards will
have extra buttons to open your email
application or the calculator for example.
Like the mouse, they have
wireless keyboards that use batteries. Like
the wireless mouse, you will need spare
batteries so when it stops functioning you
don't have to go out and buy batteries to use
your PC.
Get an IR mouse and a decent
keyboard, but I'd stay away from wireless
devices because of the dead batteries problem
that will obviously happen when you really
need to work. A good IR mouse and keyboard
with wires will not let you down.
