Supercomputer , any of a class of extremely powerful computers. The term is commonly applied to the fastest high-performance systems available at any given time. Such computers have been used primarily for scientific and engineering work requiring exceedingly high-speed computations. Common applications for supercomputers include testing mathematical models for complex physical phenomena or designs, such as climate and weather , evolution of the cosmos , nuclear weapons and reactors, new chemical compounds especially for pharmaceutical purposes , and cryptology. As the cost of supercomputing declined in the s, more businesses began to use supercomputers for market research and other business-related models.

What is computer ? Characteristics and Limitations of Computer

Speed: — As you know computer can work very fast. It takes only few seconds for calculations that we take hours to complete. You will be surprised to know that computer can perform millions 1,, of instructions and even more per second. Therefore, we determine the speed of computer in terms of microsecond part of a second or nanosecond 10 to the power -9 part of a second. From this you can imagine how fast your computer performs work.

So a computer is normally considered to be a calculating device that performs arithmetic operations at enormous speed. More accurately, a computer may be defined as a device that that operates upon information or data. Modern Definition of computers : A computer is an electronic device which is used to perform operation on raw data as per instruction given by user. All the Plugged with computer system e.

A computer is a machine that can be programmed to manipulate symbols. Its principal characteristics are:. Therefore computers can perform complex and repetitive procedures quickly, precisely and reliably. Modern computers are electronic and digital. The actual machinery wires, transistors, and circuits is called hardware; the instructions and data are called software. All general-purpose computers require the following hardware components:.


A computer is a machine that can be instructed to carry out sequences of arithmetic or logical operations automatically via computer programming. Modern computers have the ability to follow generalized sets of operations, called programs. These programs enable computers to perform an extremely wide range of tasks. A "complete" computer including the hardware , the operating system main software , and peripheral equipment required and used for "full" operation can be referred to as a computer system. This term may as well be used for a group of computers that are connected and work together, in particular a computer network or computer cluster. Computers are used as control systems for a wide variety of industrial and consumer devices. This includes simple special-purpose devices like microwave ovens and remote controls , factory devices such as industrial robots and computer-aided design , and also general-purpose devices like personal computers and mobile devices such as smartphones.

More accurately, a computer may be defined as a device that that operates upon information or data. Speed: A computer is a very fast device.

Before we go to introduction to Big Data, you first need to know What is Data? The quantities, characters, or symbols on which operations are performed by a computer, which may be stored and transmitted in the form of electrical signals and recorded on magnetic, optical, or mechanical recording media. Big Data is a collection of data that is huge in volume, yet growing exponentially with time. Big data is also a data but with huge size. In this tutorial, you will learn, What is Data?
