-
Charles Babbage thought about the illusion or the plan of computers.
The first invention of Babbage was the “mass calculator.” -
This is when "Vacume Tubes" came.
-
The invention in that is “vacuum tubes.”
The input was based on punch cards and paper tape.
The output was displayed on printouts.
The important computer examples are UNIVAC, ENIAC, and ALGOL. -
Every 1 hour these vacuum tubes burn out faster.
-
The vacuum tubes work so fast that you can get the information faster.
-
It was announced to the public. Charles Babbage thought about the illusion or the plan of computers.
The first invention of Babbage was the “mass calculator.” -
This is when "Transistors" came.
-
The main component are “Transistors.”
The input are punch cards.
The output are print outs.
examples of computer are COBOL and FORTRAN. -
They had big air conditioner to maintain.
Frequent maintenance was required. -
They were much smaller than the 1st generation.
Less heat was required -
This is when Integrated Circuits came.
-
Time Period: 1964-1971
The main component are “Integrated Circuits.”
The input are interfaced with operating systems.
The output are keyboards and monitors.
The important example was 3GL. -
Air Conditioning was required in some cases.
Technology required to manufacture the IC and it was advanced. -
It was cheaper in price.
Hardware failure was rare.
These computers were easily portable. -
Time Period: 1971-Present.
The main component was “Microprocessors.”
In this generation time sharing, real time, networks, and distributing operating system were used.
The important computer was 4GL. -
The highly advanced technology required to manufacture very large scale integration.
-
They were more reliable compared to previous ones.
These computers were the cheapest.
They were easily portable. -
They came up wih "Microprocessors".
