Processor

Processors are found everywhere, in many applications such as cars, cameras, and cell phones. A processor is the brain of the computer and it controls other parts of the computer such as the memory, the hard drive and the video card.

 Practically all computers have two processors: the central processing unit and the graphics processing unit.

The first processors were large machines that were rather slow by today's standards, though they represented a new move in computational power, which previously had to be done manually. England's Colossus Mark 1 and Mark 2, and America's ENIAC -- known as the first fully-functional computer.

UNIVAC, designed by the principle designers of the ENIAC, was the first computer made for commercial usefulness. Its processor was capable of 19,000 operations per second w/2.25 Mhz clock, and sold for millions of dollars. Another early computer was the IBM 650, which shipped first in 1954.

Despite its being a calculator processor, Intel's 4004 is widely regarded as the first microprocessor because it could be used to run more than one application.

Intel released the 8088 chip in 1979. The 8088 was a 16-bit processor and contained 29,000 transistors. This was the chip that was chosen for the first IBM PC  

Here we see different types of processor.

There are Three  types of processors. These are:
1. Intel

2. AMD 

3.ARM

Intel: 1. Pentium Pro 2. Pentium II 3. Celeron  4. Pentium II Xeon 5. Pentium III 6. Pentium II and III Xeon 7. Celeron  8. Pentium 4 9. Pentium M 10. Intel Core 11. Dual Core Xeon LV 12. Intel Pentium Dual Core 13. Intel Core 2 14. Pentium Duo 15. Pentium Dual Core 16. Core 2 Quad 16. (Newest) Intel Pentuim 2 Dual Core Processor .

AMD:( Advanced Micro Devices) AMD is the second-largest global supplier of microprocessors based on the x86 architecture  and also one of the largest suppliers of graphics processing units. It also owns 8.6% of Spansion, a supplier of non-volatile flash memory.

1.AMD Athlon 2. AMD Athlon 64 3. AMD Athlon X2 4. AMD Athlon Xp 5. AMD Duron 6. AMD Sempron 7. AMD Turion 8. AMD Opteron 9. AMD Phenom 1.

Features:

First Generation:

1.They used valves or vacuum tubes as their main electronic component.

2.They were large in size, slow in processing and had less storage capacity.

Example: ENIAC, UNIVAC, IBM 650 etc

Second Generation:

1.  Transistors were used instead of Vacuum Tube.

2.  Processing speed is faster than First Generation Computers (Micro Second)

3.  Smaller in Size (51 square feet).

Example: IBM 1400 and 7000 Series, Control Data 3600 etc.

Third generation:

     1. They used Integrated Circuit (IC) chips in place of the transistors.

2.  The size was greatly reduced, the speed of processing was high, they were more accurate and reliable.

3. Large Scale Integration (LSI) and Very Large Scale Integration (VLSI) were also developed.

Example: IBM 360, IBM 370 etc.

Fourth Generation:

1.  They used Microprocessor (VLSI) as their main switching element.

2.  They have very high speed of processing; they are 100% accurate, reliable,   diligent and versatile.

Example: IBM PC, Apple-Macintosh etc.

Defference between First, Second,Third,Fourth and Future Generation:

1.First generation computers used vaccum tubes as memory device.

2.Second generation computers used transistor.

3.Third generation computers used integrated circuits.

4.Fourth generation computers used LSI and VLSI technologies.

5.Future generation computers will be using Ultra Large Scale Integration(ULSI) technology.

Next difference between First,Second,Third,Fourth And Future Generation:

1.The operating speed was measured in milliseconds.

2.The operating speed was measured in microseconds.

3.These generation the operating speed was measured in nano seconds.

4.These generation the operating speed is measured in beyond picoseconds and MIPS(Million of instruction per seconds) and Multiprocessing and multiprogramming OS are used.

5.The speed will be extremely high in fifth generation computer.

Next Difference Between Different Generation:

1.They were extremely large and occupied a very large space.

2.They were smaller,faster and cheaper than first generation of computer.

3.They were smaller than second generation of computer,efficient and reliable.

4.4GL are also used.

5.The goal of fifth generation computers is develop machines that will be able to think and take decisions and it can perform large number of parallel processing.
