1. What is the function of the CPU?
CPU (central processing unit, which is the brain of the computer which does all the processing and calculations on data inputs and provides output on screen or printer)
2. What was the name of the first CPU?
In November, 1971, a company called Intel publicly introduced the world's first single chip microprocessor, the Intel 4004 (U.S. Patent #3,821,715). The 4004 was not very powerful -- all it could do was add and subtract, and it could only do that 4 bits at a time

3.
The speed of the CPU's overtime is gradually increasing. This means that the rate at which these mircoprocessors work is increasing.
e.g In 1974 the clock speed of this was 2 MHz.
Where as in 2004 the clock speed was 3.6 GHz.
As you can see the speed of these CPU's is increasing, this is made evident through even the changing units. In 1974 it was measured in MHz but now it is is measured in GHz, which clearly emphasises how these rates are increasing.
4. What does MIPS measure?
MIPS measure the rought performence of a CPU. The acronym MIPS stands for "millions of instructions per second.
5. Research (Google it) what is a dual core processor, what is multitasking and how do the two work together.
A dual core processor is a CPU with two separate cores on the same die, each with its own cache. It's the equivalent of getting two microprocessors in one.
A dual core processor is different from a multi-processor system. In the latter there are two separate CPUs with their own resources. In the former, resources are shared and the cores reside on the same chip. A multi-processor system is faster than a system with a dual core processor, while a dual core system is faster than a single-core system, all else being equal.

What is multitasking ?
The simultaneous execution of multiple tasks (programs) under the control of an interrupt-driven operating system; The practice or capability of handling more than one task at the same time
