Input and Output

Magnetic Ink Character Recognition(MIRC)

In computing, MIRC is a character recognition system that using special ink and character which can read and magnetised automatically. The banking industry use MICR to print details on cheques to enable automatic processing because MIRC uses magnetically chargeable ink or toner to print the numbers and special characters on the bottom of checks or other financial transaction documents and are therefore ideal for marking and identifying the account and sort code numbers on cheques.

Optical-Character Recognition(OCR)

Optical Character Recognition is the recognition of printed or written text characters by a computer. This involves photoscanning of the text character-by-character, analysis of the scanned-in image, and translation of the character image into character codes, such as ASCII, commonly used in data processing. When a character is recognized, it will converted into an ASCII code. The libraries are using OCR to digitize and preserve their holdings. OCR is also used to process checks and credit card slips and sort the mail.

Optical-Mark Recognition(OMR)

Optical Mark Recognition also called Optical Mark Reading. It is a technology of electronically extracting intended data from marked fields, such as checkboxes and fill-in fields, on printed forms and it's also a process of capturing human-marked data from document forms such as surveys and tests. OMR technology scans a printed form, reads predefined positions and records where marks are made on the form.

Dot-matrix printer

Dot matrix printer also called impact matrix printer. It is a the type of computer printer that produces characters and illustrations by striking pins against an ink ribbon to print closely spaced dots in the appropriate shape, much like a typerwriter. Although dot-matrix printers are relatively expensive, it do not produce high-quality output. However it cannot produce high-quality output but it can print to multi-page forms that laser and ink-jet printers cannot do. Dot-matrix printers have two important characteristics that are speed and print quality.

Plotter

A device that draws pictures on paper based on commands from a computer. There are two types of main plotters, pen plotters and electrostatic plotters.Plotters are different from printers because they draw lines using a pen and they can produce continuous lines but printers can only simulate lines by printing a closely spaced series of dots. Multicolour plotters use different colour pens to draw different colours. Plotters are more expensive than printers because they are used in engineering application where precision is mandatory.

Photo Printer

Photo printer usually is a injek printer. It is a printer specialized for smaller prints such as 4x6" and 5x7". Photo printer is specifically designed to print high quality digital photos on photo paper and it usually have a very high number of nozzles and are capable of printing droplets as small as 1 picoliter.

Portable Printer

Portable printer is useful for people that are travelling but who need to work while on the go because is light weight and easy to carry.It just like with laptop computers and the smaller notebooks a reduction in size will more than like reduce the power and the features, while raising the price on the product.

Fax Machine

Fax machine is a telecomunication technology that can send or receive pictures and text over a telephone line. Fax machines work by digitizing an image,it dividing it into a grid of dots. In this way, the fax machine translates a picture into bit map that can be transmitted like computer data. A fax machine reads the incoming data and translates the bitmap into dots, and reprints the picture.

Multifunctional Device

A Multifunctional Device is an office machine which incorporates the functionality of multiple devices in one. It is also a single device that serves several functions. Typically, multifunctional device act as a printer, scanner, fax machine and also a photocopier. It become popular for SOHO user is because it more cheaper than
buying four separate devices.

Internet Telephones

Internet telephones are a category of hardware and software that enables people to use the Internet as a transmission medium for telephone calls. For people who have free or fixed-price Internet access, internet telephones software can provides free telephone calls anywhere in the world. Internet telephones do not have the same quality of telephone service as direct telephone connections.
