Computer Evolution.

Computers have come a long way since their inception in the mid-20th century. The earliest computers were huge machines that used vacuum tubes and punched cards. However, with advancements in technology and computing power, computers have become smaller, faster, and more powerful.

In this blog, we’ll take a look at the different generations of computers and how they have evolved over time.

What are Computer Generations?

Computer generations refer to the different stages of development in computer technology. Each generation is characterized by a unique set of technologies and innovations that distinguish it from the previous one.

Generation

Due the reason of speed size and cost of computer , dived in to some generation which are given below:-

First Generation Computers:

The first generation of computers used vacuum tubes to process and store data. These machines were huge, expensive, and required a lot of maintenance. They were also incredibly slow and could only perform simple calculations.

I^st Generation

  Generation started about 1949

• First generation computer processor valve type
• processor made-up of with help of test Tube (glass)
• Programming language was done in machine language
• Computer were in very big size like on big room
• Speed is too slow of  first generation computer
• Due the reason of valve based processor which made-up of with help of test

Tube (glass) the processor became damage very easily and very soon .that’s why

this is generation fulfill fail

• Very large space requirement
• Limited programming capabilities
• High power consumption
• Slow operating  speed and restricted computing capacity

Computer name of 1^st edvac, LEO, UNIVAC-1, IBM70, 650

eniac– it was fist valve based computer designed by physics, jhon w mouchly.

Note:-

            Univac-1 was the world first commercially used mainframe computer of 1^st gen.

Second Generation Computers:

The second generation of computers was characterized by the use of transistors. These tiny electronic devices were much more reliable than vacuum tubes and allowed computers to be smaller, faster, and more efficient.

II^nd Generation

Generation started about 1959

• 2^nd generation computer processor transistor  type.
• Programming language was very famous In this gen. like cobol, fortran etc
• Computers were in size less than 1^st generation
• Speed is greater than 1^st generation
• programming capabilities
• Low power consumption

Model                                  Size                             Application

IBM-1620                            Small                           Scientific

IBM-1401                            Medium                       Business

IBM-7094                            Large                           Sci. & Buss.

CDC-1604                            Large                           Scientific

CDC-3600                            Large                           Scientific

RCA-501                              Medium                       Business

UNIVAC-1108                     Large                           Sci. & Buss

Third Generation Computers:

The third generation of computers saw the introduction of integrated circuits. These circuits were made up of multiple transistors and other components, allowing for even greater computing power in a smaller package.

III^rd Generation

Generation started about 1969

• 3^nd generation computer processor IC (integrated circuit)   type, consisting of Regis tens and capacitor on a single chip were used.
• Computers were in size less than 1^st & 2^nd generation.
• Higher Speed , greater than 1^st   & 2^nd generation
• Large storage capabilities and lower prices this computer called mini computer programming capabilities.
• Low power consumption

Computer of 3^rd generation IBM-360 series IBM-370, 1168 ICL-1900 Series Honey well -6000 series.

Fourth Generation Computers:

The fourth generation of computers saw the introduction of microprocessors. These tiny chips contained thousands of transistors and could perform complex calculations at lightning-fast speeds. This is the generation of computers that most people are familiar with today.

IV^th Generation

Generation started about 1980.very large scale integrated circuits having about 50000 transistors an a chip micro processor in this generation.

• Development of microprocessor made it possible in this generation.
• Computer was in very small size.
• Higher Speed , greater than 1^st , 2^nd  & 3^rd generation
• Large storage capabilities and lower prices this computer called micro computer programming capabilities.
• Low power consumption

Note:-

1. alter was the first micro computer 
2. Micro processor chips in 1971 Intel corporation of USA.

Fifth Generation Computers:

The fifth generation of computers is characterized by the use of artificial intelligence and machine learning. These computers can learn, reason, and make decisions on their own, without human intervention.

Conclusion:

The evolution of computers has been nothing short of amazing. From the huge, slow machines of the first generation to the powerful, intelligent computers of the fifth generation, computers have come a long way in just a few decades. As technology continues to evolve, we can only imagine what the future holds for these incredible machines.
