Computer:

 A computer is an electronics machine which perform high speed mathematically or logical operation.

Types of computer.

(1) Analog computer:

A analog computer we can understand those devices when performs task using continuous

 signal is called analog computer.












Uses of analog computer:

  •  It is using for measuring voltage
  •  it is use for measure pressure.
  •   It is used for electric current.
  •  It is used for measure temperature.
  •  It is very help to in using electrical field technology.
  •  It is used for field of engineering.
  •  It is used for researching.

 Example of analog computer:

 (a) thermometer. (b) speedometer. c seismometer audio tapes. VCRs (same as TV).old land-line telephones .photocopiers.

(2)Digital computer.

That device which processes the data in binary number is called digital computer.









Important note: 

This is a digital system and only understand by machine language i.e.(0,1)

How working these system. 

This is most important the user give input and suddenly computer gives output in human language,  

How Process done it. All process happening in machine language.

Next and last step. Computer and human are communicate.

USES:

  •  It is uses in digital clock
  •  It is use in ATM
  • It is use in calculator.
  • It is uses in digital weight machine.
  • It is uses in Laptop/PC
  • it is use in smartphones
  • It is uses in
  • It is uses in Automobiles
  • It is uses in Mobile Devices
  • It is uses in Navigation Systems.
  • It is uses in Servers.
  • It is uses in Personal Computer
  • It is uses in computers.
  • It is uses in Entertainment Systems.

3) HYBRID COMPUTER:

A hybrid computer is the combination of analog and digital computer and it is analog computer can do complex analyses, Where digital computer computer are the best for logic and numerical analysis.









Company name who invented the hybrid computer.

Packard Bell, a Dutch- Based computer manufacturing computer. And designed the first hybrid computer in 1961 called hybrid comp 250.

Example of Hybrid computer:

  • 1 The  Hybrid computer  used  for ULTRASOUND MACHINE.
  • 2 The  Hybrid computer  used  for DEFENCE.
  • 3 The  Hybrid computer  used  for ECH.
  • 4 The  Hybrid computer  used  for MONITORING MACHINE(ICU)

Importance of computer:

Important rule  which are helpful for our life in nowadays by computers are given below.

(1) Traveling : 

The computer make easy to traveling in every where in old day we were stand line by line but nowadays we just fill form according to computer no difficulty created just easy we got destination our points.

(2)  Education: 

The computer changed and make easy education to get knowledge and Now every where computer uses in School, college, and university.

(3) Research:

 Nowadays every scientist using computer for reaching and big thinking on researching and get easy to helping from computers.

(4) Weather forecast:

 Nowadays very very important rule in weather forecast to find weather situation from computers And  tell on social media.

(5) e-commerce: nowadays play rule in E-commerce.

(6) social network.

By the help of computer nowadays social worker social media social network helping by computers and you can see mobile ,best advance technology ,signal, traffic system , radar  system, policed system etc.

CHARACTERISTICS OF COMPUTER:

(a) Automatic:

The computer give direct answer for example when we print pages etc. we give command to pc 100 page. Itprint out  100 according to instruction no low or high fixed 100 will print out  the pages this is called best computer  technology.

(b) Speed: 

As a human comparison the computer is working very speed  Because human manual working then tired but computer never .When we give some instruction to computer it fastly giving answer but slowly human os compared to human .

(c) Accuracy:

We already studied automatic system of computer when print out pages giving accurate answer like nextstep to print no going wrong way.So the computer giving always accurate answer which human needed it.

(d) Versatility( multitasking):

The computer is to be do it multi working at one time no tired it has ability to do. It alot alot doing working as comparison to human beings.For example computer downloading play music,ms office etc.

(e) Power of remember:

When we doing somethings we will remember this things.And when after 1 year 2 years deleted our membery or can not readed that things but the the always remembers 10 years things. This the best technology of computers.

(f) Feeling: 

Computer have no feeling but human beings  have feeling.
