What is a computer?

A computer is an electronic device which can perform various logical and arithmetic operations automatically. 

It takes your data as input and then manipulates it and perform the necessary operations and gives the output to you.

Todays modern computers can perform sets of operations that can be known as programs. These programs helps the computer to perform wide range of tasks.

Classification of Computers

a)  Based on size.

Based on size

1. Super PCs :

The super PCs are the most high performing framework. A supercomputer is a PC with an elevated degree of execution contrasted with a broadly useful PC. The genuine Performance of a supercomputer is estimated in FLOPS rather than MIPS. Each of the world's quickest 500 supercomputers run Linux-based working frameworks. Extra exploration is being directed in China, the US, the EU, Taiwan and Japan to fabricate much quicker, more high performing and all the more innovatively predominant supercomputers. Supercomputers really assume a significant part in the field of calculation, and are utilized for serious calculation errands in different fields, including quantum mechanics, weather conditions guaging, environment examination, oil and gas investigation, sub-atomic demonstrating, and actual reproductions. and furthermore Throughout the set of experiences, supercomputers have been fundamental in the field of the cryptanalysis.

eg: PARAM, Jaguar, roadrunner.

2. Mainframe PCs :

These are regularly called as large iron, they are generally involved by huge associations for mass information handling, for example, statics, evaluation information handling, exchange handling and are broadly utilized as the servers as these frameworks has a higher handling ability when contrasted with different classes of PCs, the greater part of these centralized computer designs were laid out in 1960s, the innovative work worked constantly throughout the long term and the centralized servers of today are definitely more better than the prior ones, in size, limit and effectiveness.

Eg: IBM z Series, System z9 and System z10 servers.

3. Mini PCs : 

These PCs came into the market in mid 1960s and were sold at a lot less expensive cost than the principal outlines, they were really intended for control, instrumentation, human collaboration, and correspondence exchanging as particular from computation and record keeping, later they turned out to be exceptionally famous for individual purposes with advancement.

During the 60s to portray the more modest PCs that became conceivable with the utilization of semiconductors and center memory innovations, insignificant guidelines sets and more affordable peripherals, for example, the pervasive Teletype Model 33 ASR.They generally took up one or a couple of inch rack cupboards, contrasted and the enormous centralized computers that could occupy a room, there was another term "MINICOMPUTERS" begat

Eg: Personal Laptop, PC and so forth.

4. Micro PCs : 

A microcomputer is a little, somewhat cheap PC with a chip as its CPU. It incorporates a microchip, memory, and insignificant I/O hardware mounted on a solitary printed circuit board.The past to these PCs, centralized computers and minicomputers, were nearly a lot bigger, difficult to keep up with and more costly. They really shaped the establishment for present day microcomputers and brilliant contraptions that we use in everyday life.

Eg: Tablets, Smartwatches.

Based on usefulness

1. Servers : 

Servers are only devoted PCs which are set-up to offer an administrations to the clients. They are named relying upon the sort of administration they advertised. Eg: security server, information base server.

2. Workstation : 

Those are the PCs intended to fundamentally to be utilized by single client at a time. They run multi-client working frameworks. They are the ones which we use for our everyday individual/business work.

3. Data Appliances :

 They are the versatile gadgets which are intended to play out a restricted arrangement of assignments like fundamental computations, playing interactive media, perusing web and so on. They are for the most part alluded as the cell phones. They have exceptionally restricted memory and adaptability and by and large sudden spike in demand for "with no guarantees" premise.

4, Implanted PCs :

 They are the processing gadgets which are utilized in different machines to serve restricted set of prerequisites. They adhere to guidelines from the non-unpredictable memory and they are not expected to execute reboot or reset. The handling units utilized in such gadget work to those essential prerequisites just and are not quite the same as the ones that are utilized in PCs also called workstations.

Arrangement based on information dealing with

1. Analog : 

A analog PC is a type of PC that utilizes the constantly inconsistent parts of actual truth, for example, electrical, mechanical, or water powered amounts to show the issue being settled. Whatever is variable regarding time and nonstop can be guaranteed as simple very much like a simple clock estimates time through the distance went for the spokes of the clock around the roundabout dial.

2. Digital :

 A PC that performs estimations and sensible tasks with amounts addressed as digits, as a rule in the paired number arrangement of "0" and "1", "PC fit for tackling issues by handling data communicated in discrete structure. from control of the blends of the paired digits, it can perform numerical estimations, put together and examine information, control modern and different cycles, and reproduce dynamic frameworks like worldwide weather conditions.

3. Hybrid: 

A PC that processes both simple and advanced information, Hybrid PC is a computerized PC that acknowledges simple signs, changes them over completely to computerized and processes them in advanced structure.
