The major developments in computer technology are the different generations of computer.
1. THE FIRST GENERATION
The beginning of commercial computer age is from UNIVAC (Universal Automatic Computer). They were based on vacuum tubes. Examples of first generation computers are ENIVAC and UNIVAC-1.
Advantages
Vacuum tubes were the only electronic component available during those days.
These computers could calculate data in millisecond.
Disadvantages
The computers were very large in size.
They consumed a large amount of energy.
They heated very soon due to thousands of vacuum tubes.
They were not very reliable.
Air conditioning was required.
Constant maintenance was required.
Non-portable.
Costly commercial production.
Limited commercial use.
Very slow speed.
Limited programming capabilities.
Used machine language only.
Used magnetic drums which provide very less data storage.
Not versatile and very faulty.
Second Generation Computers (1955-1964)
The second generation computers a used transistors. The examples of second generation computers are IBM 7094 series,IBM 1400 series and CDC 164 etc.
Advantages
Smaller in size as compared to the first generation computers.
The 2nd generation Computers were more reliable
Used less energy and were not heated.
Wider commercial use
Better portability as compared to the first generation computers.
Better speed and could calculate data in microseconds
Used Assembly language instead of Machine language.
Accuracy improved.
Disadvantages
Cooling system was required
Constant maintenance was required
Commercial production was difficult
Only used for specific purposes
Costly and not versatile
Puch cards were used for input.
Third Generation Computers (1964-1975)
The Third generation computers used the integrated CIRCUIT (IC). Jack Kilby developed the concept of integrated circuit in 1958. It was an important invention in the computer field. The first IC was invented and used in 1961.The examples of third generation computers are IBM 370, IBM System/360,UNIVAC 1108 and UNIVAC AC 9000 etc.
Advantages
Smaller in size as compared to previous generations.
More reliable.
Used less energy
Produced less heat as compared to the previous two generations of computers.
Better speed and could calculate data in nanoseconds.
Used fan for heat discharge to prevent damage.
Maintenance cost was low because hardware failure is reare.
Could be used for high-level languages.
Good storage
Versatile to an extent
Less expensive
Better accuracy
Commercial production increased.
Used mouse and keyboard for input.
Disadvantages
Air conditioning was required.
Highly sophisticated technology required for the manufacturing of IC chips.
Fourth Generation Computers (1975-Present)
The fourth generation computers started with the invention of Microprocessor.
Advantages
More powerful and reliable than previous generations.
Small in size
Fast processing power with less power consumption
Fan for heat discharging and thus to keep cold.
No air conditioning required.
Totally general purpose
Commercial production
Cheapest among all generations
All types of High level languages can be used in this type of computers
Disadvantages
The latest technology is required for manufacturing of Microprocessors.
Fifth Generation Computers (Present & Beyond)
Scientist are working hard on the 5thgeneration computers with quite a few breakthroughs. It is based on the technique ofArtificial Intelligence (AI). Computers can understand spoken words & imitate human reasoning. Can respond to its surroundings using different types of sensors. Scientists are constantly working to increase the processing power of computers. They are trying to create a computer with real IQ with the help of advanced programming and technologies. IBM Watson computeris one example that outsmarts Harvard University Students. The advancement in modern technologies will revolutionize the computer in future.
