A computer is most imaginary machine that manages the many different types of instructions which are given by user; finally produce the accurate output for user. Computer is able to perform all types of simple and complex operations. Computer is electronic is device so it contains the different hardware components such as circuits, transistors and wires etc.

What are Different Types of Computers and Their Functions?

There are four forms of computers with their category inclusive of:

• By Size and Capacity
• By Data Handling and Operating System Capabilities
• By Based on Number of Microprocessors
• By Based on Number of Users

By Size and Capacity

Super Computer

In vintage days, massive enterprises and businesses used the supercomputer because they required massive-scale computing electricity. A supercomputer is architectural and operational totally rely on parallel and grid processing, because with the assist of thousands of processor all techniques are performed concurrently.

Supercomputer basically implemented in large scale clinical and engineering regions, because wherein required protection for large amount of database.

Some examples are:

• Titan
• Sequoia
• K Computer
• Mira
• JUQUEEN
• SuperMUC

Functions are:

• Industrial feature
• Space exploration
• Weather forecasting
• Nuclear testing

Mainframe Computer

Mainframe computer uses the number one memory including (RAM) andmore than one processor. It serves as an important processing unit for all workstations and terminals points associated with it. A mainframe laptop was designed for use process big quantities of records in pet bytes. It able controls thousands of users at one time. The call a mainframe ‘means a body to hold multiple processors and most important reminiscence.

Some examples are:

Banking, Government, Education gadget mainframe computer

Functions are:

• Government records processing
• Banking
• Insurance

Mini Computer

Minicomputer is delivered in mid-1960.This styles of computer systems is small length compare to supercomputer and mainframe pc. In which were used the different technologies including transistors and center reminiscence. “Digital Equipment Corporation” become made first minicomputer with US $161000.In this pc additionally, multiple men and women can paintings at a time without waiting, and SRAM Circuit Design and Operation as well.

Some Examples are:

• Tablet PC
• Desktop minicomputer
• Smartphone
• Notebooks

Functions are:

• Processing monitoring
• Data acquisition
• Feed lower back

Micro Computer

Micro pc is a small in length. You can say it equivalent to private computers. In Microcomputer use special technologies like as CPU(one unmarried chip), Microprocessor, Input/output devices and other garage parts. This is multi-User pc this is large gain.

Some Examples are:

• PDA
• PC
• Smartphone
• Notebooks

Functions are:

• Application processing
• Education
• Amusement

Embedded Computer

Embedded laptop is a micro controller technology based totally device, and this has been layout for unique mission. Embedded computer is not want more energy for big computing. These computer systems are able to support some gadgets.

Examples are:

• DVD
• Medical Equipment
• Printer
• Fax
• Washing Machine e

By Data Handling and Operating System Capabilities

Analogue Computer

Analog computer makes use of a few physical fact’s continuously variable for solving troubles including mechanical, hydraulic and electrical portions. Anything this is variable concerning time and ceaseless may be asserted as simple clock measures thru the separation fixed to the clock spokes through time, a great deal similar to simple clock measures.

Digital Computer

In the Digital Computer, all calculations and other operations are represented inside the shape of digits inclusive of binary gadget “zero” and “1”. These computer systems are capable of perform global weather patterns, manipulate business, mathematical calculations, and other complicating calculations as nicely.

Hybrid Computer

Hybrid Computers are combination each analog and digital computer systems, due to the fact those computers are able to execute both records along with analog and virtual. These computer systems take input inside the shape of analog alerts, convert them into virtual, and convey the output in digital shape.

Android is a Best Mobile O/S and its Latest Android Version

By Based on Number of Microprocessors

1. Sequential Computers:

The sequential computing is traditional architecture. In this version all instructions are carried out separately so velocity of this computing is slow examine to parallel computing.

1. Parallel Computers:

Parallel computing is imaging type of model in which many processors or packages execute simultaneously. In parallel computing splits the overload work into more than one processor, and computation simultaneously.

 Classification of Parallel Computing:

• Bit-level parallelism
• Instruction-stage parallelism (ILP)
• Data Parallelism
• Task Parallelism

By Based on Number of Users

1. Single User:

In this version simplest one person can perform undertaking at a time

1. Multi User:

In this model most effective more than one users can carry out undertaking at a time

1. Network Types:

In which has special capability, in this modal connect laptop and different terminals with nearby location community.
