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.

Definition - What is Docking Station?: A Docking station also known as universal port replicator or simply dock. It is like a attachment that plugging-in to a laptop or notebook computer, either directly or by cable, providing connects a laptop with more external peripheral devices. Docking station connection interfaces increases the laptop's capabilities almost to that of a standardized desktop computer. A docking station typically includes standard expansion slots, as well as additional ports (sockets or connection interfaces) for connecting a local printer, modem, keyboard, larger storage or backup drives etc.It can also include a NIC Card,a USB port that attaches notebook to LAN.

A coprocessor is a chip that works side-by-side with the computer's main processor (the chip called the central processing unit, or CPU). The coprocessor handles some of the more specialized tasks, such as doing math calculations or displaying graphics on the screen, thereby taking some of the work load off the main processor so it can go on with the business of directing and keeping order over the whole show. A coprocessor is installed to reduce the burden on a computer's CPU and thus free it for more general duties such as transferring data and handling multiple tasks.

Definition: A control unit (CU) (or controller, same thing) is a piece of hardware that manages the activities of peripherals (separate devices attached to the computer, such as monitors, hard drives, printers, etc.) Control units found on personal computers are usually contained on a single printed circuit board. The control unit acts as a sort of "go-between," executing transfers of information between the computer's memory and the peripheral. Although the CPU (central processing unit-the "big boss" in the computer) gives instructions to the controller, it is the control unit itself that performs the actual physical transfer of data.

What is Computer Bus: The electrically conducting path along which data is transmitted inside any digital electronic device. A Computer bus consists of a set of parallel conductors, which may be conventional wires, copper tracks on a PRINTED CIRCUIT BOARD, or microscopic aluminum trails on the surface of a silicon chip. Each wire carries just one bit, so the number of wires determines the largest data WORD the bus can transmit: a bus with eight wires can carry only 8-bit data words, and hence defines the device as an 8-bit device.

A computer bus normally has a single word memory circuit called a LATCH attached to either end, which briefly stores the word being transmitted and ensures that each bit has settled to its intended state before its value is transmitted.

To boot or boot up means to start your computer system, usually by turning on the power and/or pushing the "on" button. It's called "booting" because the computer is going inside itself and turning itself on (doing a lot of preliminary checking and adjusting before it's ready to run your programs). Hence the machine is considered to be "pulling itself up by its own bootstraps."

A batch file is a text file containing a series of commands that the operating system will carry out for you, one at a time. A batch file is a batches (bundles or packages) of DOS commands into a single file. MS-DOS batch files consist of the normal operating system commands (e.g. DIR, DEL, COPY and MKDIR) together with some extra commands such as IF, FOR, GOTO, SHIFT and PAUSE that provide conditional control of execution and enable PARAMETERS to be passed so that the same batch file can be used in many different contexts. Under UNIX, batch files are called SHELL SCRIPTS, and are written in a c-like scripting language.

BIOS stand for Basic Input Output System (pronounced "by ose," that's "ose" as in comatose). BIOS are a set of instructions that tell the computer how to handle the flow of information between the computer and its peripherals, such as the keyboard (input) or the printer (output). . The BIOS is firmware, meaning it is a program built into the read-only memory (ROM) in your computer, rather than stored on a disk (because The BIOS is stored in a ROM chip and automatically executed whenever the power is switched on, it's sometimes called the ROMBIOS). Since the ROM BIOS instructions are read-only memory, they cannot be changed.

Definition: Analytical Engine is known for the world’s first special-purpose mechanical computer and set the blueprint for the modern computer. It is designed by famous English Mathematician Charles Babbage between 1834 and 1846. Charles use brass gears to built the Analytical Engine, it's not electric that is powered by steam engine.

Definition: Analog computer is that computer, which is use to process continuously varying data. Everything we see and hear is change continuously. This changeable continuous stream of data is called analog data. Analog computer can be used in scientific and industrial applications such as measure the electrical current, frequency and resistance of capacitor, etc.

The name of this batch file comes from a combination of the words automatically executed batch file. Like other batch files, AUTOEXEC.BAT contains a series of DOS commands that your (IBM-compatible) PC runs for you, one after the other, so that you don't have to type the commands individually. It gives the computer various basic instructions about starting Windows, running antivirus checks in the background, identifying the keyboard, and so on.

What is 32-bit: 32-bit tells us that the number of bits that can be processed or transmitted. In another way, you can say that the number of bits that can be used for the single element in a data format.
32-bit is a type of CPU (Central Processing Unit) architecture that can transfer 32 bits of data per clock cycle or you can say that it is the amount of information that the CPU can process every time it performs an operation.

          Floppy Disk

The floppy disk drive  also known asfloppy or FDD is the primary removable storage medium for a personal computer. The FDD, once called a mini disk, is the primary medium for getting voluminous information into and out of a micro computer system.  If you have two FDDs of different storage capacities, A: In DOS and Windows the identifier used for the first floppy disk drive; the second floppy disk is designated as drive B:.

The term Ultrabook, what do they really mean? The ultrabook is a new Intel-defined format. Basically, it is a new way of calling notebooks or laptops, to differentiate a little ocean of varieties available. Unlike netbooks that are smaller but also less powerful, ultrabooks offer virtually the same comfort as laptops.

                                    NetBook

The concept of netbook is not so far from its portable design, but it is lighter and thinner, and limited storage than a laptop. Netbooks are like physical paper book; its design is just like a laptop. His name also reflects its main purpose: Net synonymous English Internet and book for "book", in short, the book for the Internet. The term netbook promoted by Intel.
