history of the computer...

1939
Hewlett-Packard is Founded. David Packard and Bill Hewlett found Hewlett-Packard in a Palo Alto, California garage. Their first product was the HP 200A Audio Oscillator, which rapidly becomes a popular piece of test equipment for engineers. Walt Disney Pictures ordered eight of the 200B model to use as sound effects generators for the 1940 movie “Fantasia.”

1988
Apple cofounder Steve Jobs, who left Apple to form his own company, unveiled the NeXT. The computer he created failed but was recognized as an important innovation. At a base price of $6,500, the NeXT ran too slowly to be popular.The significance of the NeXT rested in its place as the first personal computer to incorporate a drive for an optical storage disk, a built-in digital signal processor that allowed voice recognition, and object-oriented languages to simplify programming. The NeXT offered Motorola 68030 microprocessors, 8 megabytes of RAM, and a 256-megabyte read/write optical disk storage.

3 steps you need to know about the CPU

1st thing you need to know...
if you bought a new computer, the cpu will be covered by heatsink and a fan. keep in mind that the heatsink and the fan are important. If there are no such components the CPU would get too hot to work and possibly melt or burn out. And be very careful when you want to replace the fan if you need to have a look at your CPU.

2nd thing...
now this is about to move on the performance of your CPU and the basic functions that it carries out.
the CPU is similar to the human brain.It is artificial but the CPU is where all the logic is applied. Everything that goes on in your PC at some point goes through your CPU. if you cannot get the idea here is a simple example of it.
the computer is basically mathematics. for example, imagine you want to do a simple arithmatic. like yu want to devide 12 into 2. what happens then?
you will do fractions like 12/2 on the keyboard of your PC. the keyboard will then turn this information of ones and zeros (the code, which the computer reads).

3rd thing...
The more powerful the CPU the more kinds of applications you will be able to run on your system.

which one is old and modern CPUs???

modern CPU:
the modern CPU is smaller than the old CPUs and the modern CPU is shape as a square with many short, rounded, metallic connectors on its underside.





older CPU:
the older CPU has pins rather than metallic connectors.

Important CPU facts you need to know about

not all CPUs have pins on their bottom sides but in the ones that do have the pins, the pins are easily bent. if you have the pins in your CPU, take good care of it especially when you are installing the mother board.

each of the motherboard supports only a certain range of CPU types are always check with your motherboard manufacturer before making a purchase

what is the CPU????

The Central Processing Unit (CPU) is responsible for interpreting and executing most of the commands from the computer's hardware and software. It is often called the "brains" of the computer.

the CPU is also known as...

processor, microprocessor, central processor, "the brains of the computer"
