These are input devices, what
you do to the device is displayed on the monitor.
Keyboards like processors have came a long way since the old IBM PC, from 86
keys to the 101 key and beyond.
The mouse has not changed all that much since introduced in the late 1980's.
some came with only two buttons, some with three. Some were controlled by a ball
and some were controlled with two led's (Light emitting diodes) and metal mouse
pad with dark blue grid over a light blue back ground.
The main changes with the keyboard and mouse are how the connect to the
computer.
There is the wired and the wireless.
Wired keyboards and mouse have a cable that connects to the computer main board
with what are known as "ports" most cases today have an Icon to distinguish the
different ports. Or they can be connected with a "USB" (Universal Serial Bus)
Wireless keyboard and mouse use either RF (Radio Frequency) or IR (Infrared
Frequency) to communicate with the computer. (You can't use a wireless device on
a aircraft!!)
I am old fashioned, at home I have a wired keyboard and mouse. The laptop for
travel has two mice, a wired for on a Airliner and wireless for when I get to my
destination, I like the wireless for the laptop, sometimes you don't have a lot
of room to spread out.
So if you like to sit back three to five feet from your monitor to type, play
games, then the wireless would be a better choice.
