Analog computer

speedometer

Examples: voltage, temperature, pressure, height, light intensity, speedometer etc.

Hybrid computer

Hybrid computers are computer compatible with both analog and digital type methods. Hybrid computer uses digital membranes to store intermediate results and uses analog device for mathematical calculation, counting etc. This type of computer can convert the signal analog to digital and digital to analog. Its speed is between analog and digital.

hybrid-computer

Mini computer

Mainframe computer

The ability to store information on this type computer system is very high, can work on huge volume of data, and capable of solving complex scientific and mathematical problems, these types of computers are called mainframe computers. This is big size and so expensive computer system. This type of computer used 32 to 128 bit microprocessor chip and it's processing speed is so high about 100 MIPS (Million Instruction Per Second). It is a multi user computer system. This type of computer used in data processing center, engineering field and also used for scientific research.

mainframe-computer

Ex. IBM 4381, VAX 8000 etc.

Super computer

Super computer is a largest, high powerful and too much expensive computer system. Have maximum data storage capacity. This type of computer used 64 bit microprocessor chip and it's processing speed too high like mainframe 100 MIPS (Million Instruction Per Second). Super computer can used more than 150 user at a same time, so it is a multi user computer system. This type of computer used in space research center, robotics lab, big power hub center, bio-technology etc.

super-computer

Ex. PARAM, Cray etc.

O.T.P is One Time Password.

• It is used to verify your online transactions, mobile number verification, e-mail verification etc. OTP is also used for two step user authentication to minimize the risk of fraud. Some examples are given below:

1.  Assume you are using gmail and google ask you for enable two step verification and if you are enable two step verification then you will receive a OTP every time whenever you login to your gmail account and this is increase your security.

   OTP

2. Again assume you are using digital wallet (Paytm, FreeCharge, PhonePe etc.), now if you are going to add money to wallet (for bill payment, recharge, ticket booking etc.)by your debit card; your bank will verify your transaction by sending OTP and if you enter correct OTP then your transaction will successful.

Hope this helps!

Computer Definition: 

    The computer is a speedy and complex electronic device that can communicate various types of data in collaboration with various tools. It can store even a large amount of information and follow the instructions correctly and it also performs mathematical, logical and other tasks in step-by-step manner and gives the necessary results correctly.

How a computer works: 

Normally computer works in three steps....

   Input--->Processing--->Output

computer-structure

Input unit: 

    In input unit section we give some instruction to CPU (Central Processing Unit) to get desired results. Ex. if you want to play a music in your computer you have to go on the directory where you save the music file then select the music after that you can play the music. Here you can use mouse or keyboard as a input device.

keyboard

Name of some input device: keyboard,  mouse, touch screen, light pen, scanner, joystick, bar code reader, fingerprint scanner, webcam, voice recognizer, remote, OMR, graphics tablet etc.

Processing: CPU (Central Processing Unit)

cpu

is a brain of a computer system such as human brain is very very important part, by which we make all decision at every moment in our life. CPU is also is called brain of a computer because its makes all processes in a computer after getting a input. After complete the processing it send result to output unit.

    After complete the processes we get the result in this section by various types of output devices. Ex. same when you play the music you can hear the music by output device speaker or headphone.

Characteristics of computers:

• The computer can work for a long time, which is not possible for humans.
• The computer has control over many different types of complex machines like robots, 3D printer, satellite system.
• Computers can exchange information quickly. 

Uses of computer: 

• Most of the educational sector (like school, colleges) used computer to give practical training.
• The computer is used in medical department. Ex. X-ray, scanning, sonography etc.
• Computer is used in robotics technology.
• Now time computer is a very important thing in the research center. Ex. Bio-chemical research center, medical research center, genetic lab, nuclear research center etc.
• Each and every country is used computer in defense system.
• Video editing, graphics design and also used in cinematography.

Advantages of computer:

• The computer can work for a long time, which is not possible for humans.
• Can solve the complex problems very quickly.
• Computer can design anything very well.
• With the help of computer we can store big size of data easily.
• It is very easy to communicate with different parts of the world through computer.
• Now it is possible to trade in the stock market by computer sitting at home.

Dis-advantages of computer:

• Increasing people's laziness due to use of computer.
• Many real data can be distorted with the help of computers.
• Increasing data theft.
• It is very easy to destroy information by computer viruses.
• Hacking is increasing day by day.
