CPU__

CPU is the component in a digital computer that interprets computer program instructions and processes data. CPUs provide the fundamental digital computer trait of programmability, and are one of the necessary components found in computers of any era, along with primary storage and input/output facilities. A CPU that is manufactured as a single integrated circuit is usually known as a microprocessor. Beginning in the mid-1970s, microprocessors of ever-increasing complexity and power gradually supplanted other designs, and today the term "CPU" is usually applied to some type of microprocessor.

RAM ___

RAM is a type of data store used in computers. It takes the form of integrated circuits that allow the stored data to be accessed in any order — that is, at random and without the physical movement of the storage medium or a physical reading head.

Motherboard___

A motherboard, also known as a mainboard, system board, or logic boards on Apple computers, and sometimes abbreviated as mobo (generally credited to the magazine Maximum PC) is the central or primary circuit board making up a complex electronic system, such as a modern computer.

HDD (hard disk drive)

A hard disk (commonly known as a HDD (hard disk drive) or hard drive and formerly known as a fixed disk) is a non-volatile storage device which stores digitally encoded data on rapidly rotating platters with magnetic surfaces. Strictly speaking, "drive" refers to an entire unit containing multiple platters, a read/write head assembly, driver electronics, and motor while "hard disk" (sometimes "platter") refers to the storage medium itself. [1]

CD/RW DRIVE

CD-ROM (an abbreviation of "Compact Disc read-only memory") is a Compact Disc that contains data accessible by a computer. While the Compact Disc format was originally designed for music storage and playback, the format was later adapted to hold any form of binary data. CD-ROMs are popularly used to distribute computer software, including games and multimedia applications, though any data can be stored (up to the capacity limit of a disc). Some CDs hold both computer data and audio with the latter capable of being played on a CD player, whilst data (such as software or digital video) is only usable on a computer. These are called Enhanced CDs.

DVD Burner

A DVD recorder (or, colloquially, a DVD burner) is an optical disc recorder that records video onto blank writable DVD media. Such devices are available as either installable drives for computers or as standalone components for use in studios or home theater systems.

Floppy disk drive___

A floppy disk is a data storage device that is composed of a disk of thin, flexible ("floppy") magnetic storage medium encased in a square or rectangular plastic shell. Floppy disks are read and written by a floppy disk drive or FDD, the latter initialism not to be confused with "fixed disk drive", which is an old IBM term for a hard disk drive.

USB___

Universal Serial Bus (USB) is a serial bus standard to interface devices. It was originally designed for computers, but its popularity has prompted it to also become commonplace on video game consoles, PDAs, portable DVD and media players, cellphones; and even devices such as televisions, home stereo equipment (e.g., digital audio players), car stereos and portable memory devices. The radio spectrum based USB implementation is known as Wireless USB.

Keyboard

A computer keyboard is a peripheral partially modeled after the typewriter keyboard. Keyboards are designed for the input of text and characters and also to control the operation of a computer.

Mouse

A mouse (plural mice or mouses) is a computer pointing device; it is designed to detect two-dimensional motion relative to its supporting surface and consists of a small case, to be held under one of the user's hands, and one or more buttons. It sometimes features other elements, such as "wheels", which allow the user to perform various system-dependent operations, or extra buttons or features can add more control or dimensional input. The mouse's motion typically translates into the motion of a pointer on a display.

Graphics___

Computer Graphics is a publication of ACM SIGGRAPH. It has published the yearly proceedings of the annual SIGGRAPH conferences, as well as a variety of papers on a quarterly basis. Since 2003, all printed materials from the annual conference are included in an issue of ACM Transactions on Graphics (TOG).

Video card___

A video card, (also referred to as a graphics accelerator card, display adapter and numerous other terms), is an item of personal computer hardware whose function is to generate and output images to a display. The term is usually used to refer to a separate, dedicated expansion card that is plugged into a slot on the computer's motherboard, as opposed to a graphics controller integrated into the motherboard chipset.

Sound card___

A sound card is a computer expansion card that can input and output sound under control of computer programs. Typical uses of sound cards include providing the audio component for multimedia applications such as music composition, editing video or audio, presentation/education, and entertainment (games). Many computers have sound capabilities built in, while others require these expansion cards if audio capability is desired.

Modern__

Computer Modern is the family of typefaces used by default by the typesetting program TeX. It was created by Donald Knuth with his METAFONT program, and was most recently updated in 1992. The Computer Modern typefaces are described in great detail (including full source code) in the book Computer Modern Typefaces, volume E in the Computers and Typesetting series, which is unique in the history of font design

Wireless card___

A wireless network interface controller (WNIC) is a network card which connects to a radio-based computer network, unlike a regular network interface controller (NIC) which connects to a wire-based network such as token ring or ethernet. A WNIC, just like a NIC, works on the Layer 1 and Layer 2 of the OSI Model. A WNIC is an essential component for wireless desktop computer. This card uses an antenna to communicate through microwaves. A WNIC in a desktop computer is mostly located in the PCI slot. Other options are USB WNIC, PCMCIA WNIC and integrated WNIC (typically in Mini PCI/PCI Express Mini Card form).

Cooling___

Computer cooling is the practice of relieving heat, a potentially damaging byproduct of operation, from electronic computers

Case__

a computer. Cases are usually constructed from steel, aluminum, or plastic, although other materials (such as wood and perspex) have also been used in case designs
