Early History Computers
Charles Babbage thought about the illusion or the plan of computers.
The first invention of Babbage was the “mass calculator.” -
Period: to
First Generation Computers
This is when "Vacume Tubes" came. -
First Generation Computers (Info)
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. -
First Generation Computer (Disadvantages)
Every 1 hour these vacuum tubes burn out faster. -
First Generation Advantages
The vacuum tubes work so fast that you can get the information faster. -
It was annouced to the public
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.” -
Period: to
Second Generation
This is when "Transistors" came. -
2nd Generation (Info)
The main component are “Transistors.”
The input are punch cards.
The output are print outs.
examples of computer are COBOL and FORTRAN. -
2nd Generation (Disadvantages)
They had big air conditioner to maintain.
Frequent maintenance was required. -
2nd Generation (Advantages)
They were much smaller than the 1st generation.
Less heat was required -
Period: to
Third Generation
This is when Integrated Circuits came. -
3rd Genration (Info)
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. -
3rd Genration (Disadvantages)
Air Conditioning was required in some cases.
Technology required to manufacture the IC and it was advanced. -
4rd Generation (Advantages)
It was cheaper in price.
Hardware failure was rare.
These computers were easily portable. -
4th Generation (Info)
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. -
4th Generation (Disadvantages)
The highly advanced technology required to manufacture very large scale integration. -
4th Generation (Advantages)
They were more reliable compared to previous ones.
These computers were the cheapest.
They were easily portable. -
Period: to
4th Generation
They came up wih "Microprocessors".
