what are the generation of processor and its advantages and disadvantages

 Generation of  micro processor

1. 1st generation (1971): Instruction / processor sequentially capacities are used best component. It could perform simple arithmetic and logical operations such as addition, subtraction , Boolean OR and Boolean AND.  
2. 2nd generation (1979) : Enough transistors are available. it is 16arithmatic and pipe line processing. the case of new  semiconductor technology. EX-INTEL 8008.
3. 3rd generation (1980) :  16 bit micro processor produced. it can find more stages than pipeline. an measure work station manufacture begin developing the won micro process (RISC) type. most popular one is the INTEL 80386.
4. 4th generation (1995) : It is slightly faster and more power efficient . more than use instruction for cycle . INTEL -80386 and Motorola's 68020/68030 were popular processors.
5. 5th generation  : Processors are designed to deliver significantly enhanced graphics and increased performance in smaller thermal envelope. such processors include Pentium ,Celeron ,Dual and Quad-core processors. 

Advantages:

• They are general purpose electronic processing device which can be program to execute the no. of task.
• There is no need to program microprocessor and write software when used in embedded system. speed ,data movement ,computer arithmetic , intelligence ,flexible , compact , easy maintenance.
• The microprocessor is very versatile.
• It is portable.
• Low power consumption.         

Disadvantages :

• It might get own heated.
• Microprocessor has a limitation on the size of data.
• It's over heating physically.        
• It is based on machine language.
