Question

Explain the difference between the different generation of computers and how did science contribute to these development.

Answer 1

Answer:

Generation of computer technology refers to the changes nade in the computers technology over the time . Earlier, computer used to be a big machine with a lot of heavy wiring , whereas nowadays , a computer can be carried in hands . Initially , the changes made were limited to those made in hardware technology. However , now it includes both hardware and sodtware developments . The table given below shows the five generation of computers.

Answer 2

$\huge\underline{\overline{\mid{\bold{\red{Answer}\mid}}}}$

Generation: 1st

Time period: 1940--1956

Development: vacuum tubes

characteristics:

(1) huge in size

(2) expensive

(3) lot of electricity consumption

(4) heat generation

Generation 2nd

time period: 1956--1963

Development: Transistors

Characteristics:

(1) Frequent shutdowns

(2) Superior to 1st generation

(3) small in size and fast

(4) Cheaper as compared to 1st generation

(5) Less consumption of electricity

Generation 3rd

Time period: 1963--1971

Development: IC

characteristic;

(1) Keyboards and monitors

(2) OS

(3) Smaller and further cheaper

generation 4th

time period: 1971--2010

Development: Microprocessor

Characteristics:

(1) Use of internet

(2) GUI

(3) Introduction of portable devices like mobiles, laptops, etc.

Generation 5th

Time period: 2010--Till date

Development: Artificial intelligence (AI)

characteristics:

(1) voice recognition

(2) sensors

(3) nano technology

1st generation computers occupied the entire room, but due to advancement in science and technology, today's computer fits into our pockets.

initially computers need a specific language to interact but today we use voice recognition for the same.

in this ways, science has contributed in making the computers faster, smaller, cheaper and much more useful.
