Laser printer

A laser printer is printer that produces high quality text and graphics on plain paper at a high speed.

magnetic-ink character recognition(MICR)

A character recognition technology that is used mostly by the people in the banking industry. This technology allows computers to read information from printed documents.

Optical-Character recognition(OCR)

A mechanical or electronic translation of scanned images writings or printed text into machine-encoded text. It is usually used to convert books and documents into e-books and e-documents.

Optical-mark recognition 

 A process of reading data from document forms such as surveys and tests.

Secondary Storage

File Compression

A process of encoding information using fewer bits. It can be used to compress or shrink a file

Head Crash

A head crash is a hard disk failure that occurs when a read-write head of a hard disk drive touches its rotating platter, resulting in permanent and usually fatal damage to the magnetic media on the platter surface

Internet hard Drive

Internet hard drive offers a means of accessing computer files from any computer, as long as that computer has access to the Internet

Optical Disc drive

Optical disc drive is a disk drive that uses laser light or electromagnetic waves near the light spectrum as part of the process of reading or writing data to or from optical discs.

Solid-state storage

A data storage device that uses solid-state memory to store persistent data

The System Unit

Flash Memory

It can be called as Flash RAM. It is a type of constantly-powered nonvolatile memory that can be erased and reprogrammed in units of memory called blocks. Flash memory is often used to hold control code such as the basic input/output system (BIOS) in a personal computer.

 

 Graphic cards

Graphics cards, also known as video cards, graphics accelerators or display cards are computer hardware that takes binary data.The data compressed into a system of just two digits, 1s and 0s and it then converts this data into images that are displayed on the computer's monitor



 Sound cards

A sound card is also refered as an audio card. It- is a peripheral device that attaches to the ISA or PCI slot on a motherboard to enable the computer to input, process, and deliver sound.

Bus Line

A collection of wires through which data is transmitted from one part of a computer to another. You can think of a bus as a highway on which data travels within a computer.

HDMI
HDMI (High-Definition Multimedia Interface) is a compact audio/video interface for transmitting uncompressed digital data. It is a digital alternative to consumer analog standards.

Cache Memory

Cache memory is random access memory (RAM) that a computer microprocessor can access more quickly than it can access regular RAM. As the microprocessor processes data, it looks first in the cache memory and if it finds the data there.
