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: 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.

Computers internal architectural design comes in different types and sizes, but the basic structure remains same of all computer systems.

The term 'computer hardware' or 'computer parts' is used to describe computer components that can be seen and touched. The major components of general-purpose computer system are Input Unit, main/internal Memory or Storage Unit, Output Unit, Central Processing unit. The CPU is further includes Arithmetic logic unit (ALU) and control unit (CU). All the units also referred to as "The functional units”. Devices that are not integral part of CPU referred to as peripherals.

Cloud Computing Definition is that it is a shared pool of configurable computing resource (eg. networks, servers, storage, applications, and services) network on demand over the internet. Cloud computing literally, is the use of remote servers (usually accessible via the Internet) to process or store information. Access is usually using a Web browser. Save files on a server via the Internet is one example.

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.

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.

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.

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.

The mouse and keyboard are your PC’s eyes and ears; without them you could not execute commands or input text. In this article we’ll highlight some of their important features.

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."
