Types of Computers

The type of computer is a question that most of you might find confusing, as all you have heard about since childhood is a Personal Computer(PC).

But it would help if you learned that there are various types of computers other than PC, such as:

Personal Computers

• No need to mention much about these computers. The computers we use in our daily lives for various purposes, such as offices, making presentations, billing at a counter, and educational goals, will fall under this category.

Supercomputers

• These computers are way more advanced than the regular computers used in our households and offices.
• These computers can process large amounts of data in a few milliseconds, which organizations like ISRO for very complex calculations about the distance between planets and various other organizations.
• There have been instances where a question regarding India’s first Supercomputer was asked. This also comes under your Static GK, and such factual information should be read while preparing.

Hybrid Computers

• A hybrid computer is a computer that has the features of both an analogue and a functional computer.
• It was basically designed to facilitate working with an analogue computer with a strong capability to perform calculations and a good digital memory.
• In this case, you should make sure that you read about the year in which the first hybrid computer was developed, i.e., 1961.

Input/ Output Devices

• Input and output are the topics that you find difficult as you cannot understand the difference between the two of these components of a computer. It can be understood with a simple example of an electronic pen and touch screen tablet.
• The electric pen or stylus can be considered the output, then used to put a message onto the tablet's screen. This command being put in is the input.
• Therefore, input is anything that a user puts as a command into the system to get a response to that input called the output.

Arithmetic Logic Unit

This is also called “The Brain of Computer” as it performs the arithmetic and logic operations based on operands in computer systems.

Data Size

• The data in computers can also be measured just like other quantifiable things in our daily life, such as sales, profit, etc., and the unit to measure such parameters is money.
• Similarly, the basic unit of measuring or quantifying data in computing language is BITS and BYTES, where BITS is the smallest data unit.

There are other data units other than the two mentioned above, and they have a hierarchy of such units. The units, from smallest to largest, are as follows:

Remember that every bigger unit has 1024 units preceding a smaller one.

For example:

1 megabyte is equal to 1024 kilobytes, and 1 gigabyte is equal to 1024 megabytes. Learning the hierarchy stated above is essential as it cannot be changed.

One more point should be remembered: there is a difference between bits and bytes because you may use both these terms interchangeably and still use them sometimes because of their same pronunciation.

IP address

• It stands for Internet Protocol Address. In simple words, it can be described as the DNA of every computer system in this world as it is unique for the system.
• Questions have been asked regarding its full form in previous year’s exams of various states.

• There is one more concept in the world of computers that is quite new, i.e., Optic Fiber. It is more of an amalgamation of computers and physics.
• These ultra-thin cables are used for wireless services by all broadband services to provide the best speed to their users.

Timeline of Internet

Like there is a history of everything. Similarly, the computer world carries a long evolutionary history.

It would help if you made notes in the form of a FLOW CHART to record the history of the internet, how it started, the critical years of breakthrough inventions and discoveries, founders, and companies being incorporated. For example:

• 1941:  Alan Turing built the prototype of a computer for decoding messages during world war.
• 1958: the invention of Integrated Chips led to another revolution in the field of computer science, which boosted advanced processing.
• 1968: INTEL was founded by ROBERT NOYCE
