Grid computing is a group of computers physically connected (over a network or with Internet) to perform a dedicated tasks together, such as analysing e-commerce data and solve a complex problem. Grids are a form of "super virtual computer" that solve a particular application.The grid size may vary from small to large enterprises network.

A computing grid is constructed with the help of grid middleware software that allows them to communicate. middleware is used to translates one node information passed stored or processed information to another into a recognizable format. It is the form of "distributed computing" or "peer-to-peer computing".

"Who invented the first computer?" is not an answer to be replied in one word or name and you are sorted, the answer is not depends on single machine, computer is made up collection of different parts, each part is a separate invention and it’s separate inventor. So the answer depends on different classification of computers.

Computer has making human life faster because of its incredible speed,Accuracy and storage, with which human can save anything and search it out easily when needed. We can say computer a versatile machine because it is very flexible in performing their jobs. but Computers have several important advantages and disadvantages.

In 1640s, Computer term was first used as "one who calculates."  From 1897, term changed and got a new computer meaning "Calculating machine". From 1945 the term indicates as "programmable digital electronic computer".

You’ve probably heard in computing industry, when you download a piece of software, the term 32-bit and 64-bit. Definition of term is that, it is used for processor, Operating System, install a game, computer driver etc.so we help you understand what the difference need to know about 32-bit vs. 64-bit architecture.

Definition: A supercomputer is the fastest computer in the world that can process a significant amount of data very quickly. The computing Performance of a "supercomputer" is measured very high as compared to a general purpose computer. The computing Performance of a supercomputer is measured in FLOPS (that is floating-point operations per second) instead of MIPS. The supercomputer consists of tens of thousands of processors which can perform billions and trillions of calculations per second, or you can say that supercomputers can deliver up to nearly a hundred quadrillions of FLOPS.

Definition: A minicomputer is also known as mini. It is a class of small computers that was introduced into the world in the mid-1960s. A minicomputer is a computer which has all the features of a large size computer, but its size is smaller than those. A minicomputer lies between the mainframe and the microcomputer because its size is smaller than the former one and larger than the latter one. A minicomputer is also called as a mid-range computer. Minicomputers are mainly multi-users systems where more than one user can work simultaneously. Mini computer examples: IBM’s AS/400e, Honeywell200, TI-990

Definition: Micro Computer is a small computer. Your personal computers are equivalent to the microcomputer. Mainframe and Mini Computer is ancestor of microcomputer. Integrated Circuit fabrication technology reduces the size of Mainframe and Minicomputer.
Technically, a microcomputer is a computer in which the CPU (central processing unit, the brains of the computer) is contained on one single chip, a microprocessor, input/output devices and storage (memory) unit. All these components are important for a proper working of microcomputer.

The Definition and meaning of mainframe has shifted from its original reference to the main housing, or frame, that contained the central processing unit (CPU) of the computer. In those days, all computers were big-like the size of a garage and the frame for the CPU might have been as big as a walk-in closet. Now mainframe refers to the kind of large computer that runs an entire corporation.

Definition: ENIAC stands for Electronic Numerical Integrator and Computer. ENIAC was introduced in the world by J. Presper Eckert and John Mauchly at the University of Pennsylvania. Earlier ENIAC was used to calculate the artillery firing tables for the Ballistic Research Laboratory of United States Army.

ENIAC was the first electronic computer which was used for general purposes like solving numerical problems.The first task done by ENIAC was performing calculations for the manufacturing of a hydrogen bomb.ENIAC can be reprogrammed for the salvation of the computer related problems.
