Around 50 years ago only scientists such as the people of NASA owned a computer.

It was said by the president of Digital Equipment Corporation in 1977 " There is no reason why anyone would want to have a computer in their home"

Now everywhere you go computer are used in some way whether it is taking money out of an ATM machine or to help controlling planes. Even employers are asking more often for their employees to have some knowledge of IT.

Evaluate Hardware Devices

Hardware is the physical components of the computer. This can include the monitor, keyboard and mouse.

In all business they would like a computer that is fast and efficient. They do not want a computer that is slow time wasting, as this can be very frustrating in a busy business environment.

Using specific hardware devices you can improve the speed of your computer and they are many ways to do this, here are some of those options: -

Moving Circuits Closer Together

It is said by Parker (2000)"Shorter circuits require less time to move bit2" .

Now to make computers faster computer chip makers have placed circuits closer together and now they fit several million circuits on a single finger sized chip. The advantage is that they have faster performance in the machine. The disadvantage however is that, as when circuits are in use produce heat closer together they tend to become hot enough to melt the chip. This process is also known as Microminiaturization. From this development researchers are also trying to speed up circuitry functions through the use of superconductivity, the phenomenon of decreased electrical resistance observed in certain materials at very low temperatures.

Reduced Instruction Set Computing

Reduced instruction set computing is also known as RISC. According to French (1996)...
