A graphics tablet (also known as a digitizer,drawing tablet, digital drawing tablet, pentablet, or digital art board) is a computer input device that enables a user to hand-draw images, animations and graphics, with a special pen-like stylus, similar to the way a person draws images with a pencil and paper.

A camera is an optical instrument for recording or capturing images, which may be stored locally, transmitted to another location, or both.

Video capture is the process of converting an analog video signal—such as that produced by a video camera or DVD player—to digitalvideo. The resulting digital data are computer files referred to as a digital video stream, or more often, simply video stream.

A trackball is a computer cursor control device used in many notebook and laptop computers. The trackball is usually located in front of the keyboard toward the user. Essentially, the trackball is an upside-down mouse that rotates in place within a socket.

A barcode reader (or barcode scanner) is an electronic device that can read and output printed barcodes to a computer. Like a flatbed scanner, it consists of a light source, a lens and a light sensor translating optical impulses into electrical ones.

a video camera that inputs to a computer connected to the Internet, so that its images can be viewed by Internet users.

a handheld controller for video games.

a lever that can be moved in several directions to control the movement of an image on a computer or similar display screen.

A keyboard is the set of typewriter-like keys that enables you to enter data into a computer or other devices. Computer keyboards are similar to electric-typewriters but contain additional typing keys.

an instrument for converting sound waves into electrical energy variations, which may then be amplified, transmitted, or recorded.

or MIDI cable to other devices connected and operating on the same MIDIprotocol interface.

An electronic whiteboard is a hardware device that is similar to a whiteboard that is found in schools and businesses. It transmits any information written it to a computer or multiple computers. They also allow live interaction with digital objects on the screen.

A digital pen is an input device which captures the handwriting or brush strokes of a user, converts handwritten analog information created using "pen and paper" into digital data, enabling the data to be utilized in various applications.

come in hand-held, feed-in, and flatbed types and for scanning black-and-white only, or color.

Magnetic tape data storage is a system for storing digital information on magnetic tapeusing digital recording. Modern magnetic tape is most commonly packaged in cartridges and cassettes. The device that performs writing or reading of data is a tape drive.

Magnetic Ink Character Recognition is a character recognitionsystem that uses special ink and characters. When a document that contains this ink needs to be read, it passes through a machine, which magnetizes the ink and then translates the magnetic information intocharacters. MICR technology is used by banks.

A computer punched card reader or justcomputer card reader is a computer input device used to read executable computerprograms and data from punched cards undercomputer control. A computer card punch is acomputer output device that punches holes incards under computer control.

Optical Mark reading (OMR) is a method of entering data into a computer system. Optical Mark Readers reads pencil or pen marks made in pre-defined positions on paper forms as responses to questions or tick list prompts.

an instrument or device used for observing, checking, or keeping a continuous record of a process or quantity.

a machine for printing text or pictures onto paper, especially one linked to a computer.

a piece of equipment that marks out points on a chart

an object that is used to project rays of light, especially an apparatus with a system of lenses for projecting slides or film onto a screen.

An LCD projector is a type of video projectorfor displaying video, images or computer data on a screen or other flat surface. It is a modern equivalent of the slide projector or overheadprojector.

Computer output microfilm is the product of copying information from electronic media onto microfilm. COM technology, with a history that dates back to the first patent for microphotography in 1839, has been used for document and newspaper archival since the 1920s.

A speaker is a term used to describe the user who is giving vocal commands to a software program. 2. A hardware device connected to a computer's sound card that outputs sound generated by the computer.

Headphones (or head-phones in the early days of telephony and radio) are a pair of small listening devices that are designed to be worn on or around the head over a user's ears. They are electroacoustic transducers, which convert an electrical signal to a corresponding sound in the user's ear.

A film recorder is a graphical output device for transferring digital images to photographicfilm. All film recorders typically work in the same manner. The image is fed from a host computer as a raster stream over a digital interface.

a flat piece of film containing microphotographs of the pages of a newspaper, catalog, or other document.

a rigid nonremovable magnetic disk with a large data storage capacity.

a small plastic disc on which music or other digital information is stored, and from which the information can be read using reflected laser light.

tape used in recording sound, pictures, or computer data.

A hub is a small Network Device. A hub joins multiple computers (or other network devices) together to form a single network segment. On this network segment, all computers can communicate directly with each other. Ethernet hubs are by far the most common type, but hubs for other types of networks such as USB also exist. 

Network repeaters regenerate incoming electrical, wireless or optical signals. With physical media like Ethernet or Wi-Fi, data transmissions can only span a limited distance before the quality of the signal degrades. Repeaters attempt to preserve signal integrity and extend the distance over which data can safely travel. 

Network Bridge is networking hardware that connects multiple network segments. A Network Bridge Devicereads the outermost section of data on the data packet, to tell where the message is going .only the outermost hardware address of the packet. 

A Network Router is a network device with interfaces in multiple networks whose task is to copy packets from one network to another. Router gives path to data packet to destination. Routers provide connectivity inside enterprises, between enterprises and the Internet, and within an Internet Service Provider (ISP). 

A CSU/DSU (Channel Service Unit/Data Service Unit) is a hardware device about the size of an external modem that converts a digital data frame from the communications technology used on a local area network (LAN) into a frame appropriate to a wide-area network (WAN) and vice versa. 

Network brouter (pronounced BRAU-tuhr or sometimes BEE-rau-tuhr) is a network bridge and a router combined in a single product. A bridge is a device that connects one local area network (LAN) to another local area network that uses the same protocol (for example, Ethernet or token ring). 

Intro to Computer

(Computer System Organization)

A breadboard is a construction base for prototypingof electronics. Originally it was literally a bread board, a polished piece of wood used for slicing bread. In the 1970s the solderless breadboard(AKA plugboard, a terminal array board) became available and nowadays the term "breadboard" is commonly used to refer to these. "Breadboard" is also a synonym for "prototype".

Because the solderless breadboard does not requiresoldering, it is reusable. This makes it easy to use for creating temporary prototypes and experimenting with circuit design. For this reason, solderless breadboards are also extremely popular with students and in technological education. Older breadboard types did not have this property. Astripboard (Veroboard) and similar prototypingprinted circuit boards, which are used to build semi-permanent soldered prototypes or one-offs, cannot easily be reused. A variety of electronic systems may be prototyped by using breadboards, from small analog and digital circuits to complete central processing units (CPUs).
