MICR
Short for Magnetic-Ink Character Recognition, MICR is a font capable of recognition using magnetically charged ink. Computers equipped with the right hardware and software can print or read the character printed in such ink.
MICR font is commonly used to print checks, deposit slips, mortgage coupons, etc. There are several MICR fonts, the MICR E-13B font is used in the Canada, Panama, Puerto Rico, UK, and the United States. The MICR CRC-7 was created according to the ISO standards and is a font used in France, Mexico, Spain, and most other Spanish speaking countries.
Joystick
An input device that looks similar to a control device you would find on an arcade game at your local arcades. Ajoystick allows an individual to move an object in a game such as navigating a plane in a flight simulator. In the picture to the right, is of the Logitech Freedom 2.4 joystick and an example of what a Joystick may look like.DOT matrix
- The term DOT matrix refers to the process of placing dots to form an image; the quality of the image being determined by the dots per inch.
-
Alternatively referred to as a pin printer, Dot matrix printers were first introduced by Centronics in1970 and is a printer that uses print heads to shoot ink or strike an ink ribbon to place hundreds to thousands of little dots to form text or images. Today, Dot matrix printers are rarely used or found because of the low quality print outs when compared to ink jet printers and laser printers. In the picture to the right, is an example of what a dot matrix printer may have looked like.
Projector
An output device that can take the display of a computer screen and project a large version of it onto a flat surface. Projectors are often used in meetings and presentations to help make sure everyone in the room can view the presentation. In the picture to the right, is aViewSonic projector and an example of what a projector may look like. Projectors used with computers are small devices that are rarely much larger than a toaster and typically weigh a few pounds.Barcode
Lines of different widths and sizes representing data, that when read will determine what the scanned object is. Barcodes are often used to help organize and index information or prices about an object. Barcodes used by the U.S. postal service that helps speed the delivery of mail is another perfect example of how a barcode could be used. In the picture to the right, is an example of what a barcode for an address may look like.
Barcode readers and scanners
A barcode reader or scanner, also known as a point of sale (POS) scanner is a hardware device capable of reading a barcode and printing out the details of the product or logging that product into a database. A perfect example of a barcode reader is a super market barcode scanner that reads and logs the price of a product. In the picture to the right, is an example of a Barcode reader from HP.
Today many smart phones with the proper apps are also capable of scanning and reading barcodes.
Barcode Printers
A hardware device capable of printing out adhesive barcodes that can be attached to a product. This helps identify the product or a company keep track of its inventory.
Voice recognition
Alternatively referred to as speech recognition, voice recognition is an ability of a computer, computer software program, or hardware device to decode the human voice into digitized speech that can be interpreted by the computer or hardware device. Voice recognition is commonly used to operate a device, perform commands, or write without having to operate a keyboard, mouse, or press any buttons. Today, this is done on a computer with automatic speech recognition(ASR) software programs. Many ASR programs require the user to "train" the ASR program to recognize their voice so that it can more accurately convert the speech to text. For example, a user could say "open Internet" and the computer would open an Internet browser and allow that user to browse the Internet.
The first ASR device was used in 1952 and recognized single digits spoken by a user (it was not computer driven). Today, ASR programs are used in many industries, including Healthcare, Military (i.e. F-16 fighter jets and helicopters), Telecommunications and Personal computing (i.e. hands free computing).
Laser printer
First developed at Xerox PARC by Gary Starkweather and released in 1971, a laser printer is a printer that utilizes laser technology to print images on the paper. Laser printers are often used in corporate, school, and other environments that require print jobs to be completed quickly and in large quantities. In the picture to the right, is an example of what a laser printer may look like. This picture is of theLexmark C782n laser printer and as can be seen much larger than an ink jet printer found in most homes. Finally, below is a chart of the steps a laser printer takes to print.
