Charles Babbage KH FRS was an English polymath. A mathematician, philosopher, inventor, and mechanical engineer, Babbage originated the concept of a digital programmable computer. Babbage is considered by some to be the “father of the computer”.

A desktop is a computer display area that represents the kinds of objects one might find on top of a physical desk, including documents, phone books, telephones, reference sources, writing and drawing tools, and project folders.

A cathode-ray tube is a vacuum tube containing one or more electron guns, the beams of which are manipulated to display images on a phosphorescent screen. The images may represent electrical waveforms, pictures, radar targets, or other phenomena. A CRT on a television set is commonly called a picture tube.

A liquid-crystal display (LCD) is a flat-panel display or other electronically modulated optical devices that uses the light-modulating properties of liquid crystals combined with polarizers. Liquid crystals do not emit light directly, instead of using a backlight or reflector to produce images in color or monochrome.

A supercomputer is a computer with a high level of performance as compared to a general-purpose computer. The performance of a supercomputer is commonly measured in floating-point operations per second instead of million instructions per second.

The maximum amount of data transmitted over an internet connection in a given amount of time.

Batch applications are processed on the mainframe without user interaction. A batch job is submitted on the computer; the job reads and processes data in bulk perhaps terabytes of data and produces output, such as customer billing statements.

Digital data, in information theory and information systems, is information represented as a string of discrete symbols each of which can take on one of only a finite number of values from some alphabet, such as letters or digits. An example is a text document, which consists of a string of alphanumeric characters.

The CPU is the brain of a computer, containing all the circuitry needed to process input, store data, and output results. The CPU is constantly following instructions of computer programs that tell it which data to process and how to process it.

Integrated Circuits or an IC is defined as a microchip on which thousands and hundreds of electrical components, such as resistors, capacitors, and transistors, are fabricated. An IC functions as an oscillator, amplifier, microprocessor, timer, or as computer memory.

A computer is a digital electronic machine that can be programmed to carry out sequences of arithmetic or logical operations (computation) automatically.

Volatile memory is the memory that can keep the information only during the time it is powered up. In other words, volatile memory requires power to maintain the information.

C is a general-purpose, procedural computer programming language supporting structured programming, lexical variable scope, and recursion, with a static type system. By design, C provides constructs that map efficiently to typical machine instructions.

SQL is a domain-specific language used in programming and designed for managing data held in a relational database management system, or for stream processing in a relational data stream management system.
