MICR-Magnetic Ink Character Reader
MICR stands for Magnetic Ink Character Recognition. It is a technology which allows machines to read and process cheques enabling thousands of cheque transactions in a short time. MICR code is usually a nine digit code comprising of some important information about the transaction and the bank.
The first three digits in the MICR code represent the city code that is the city in which the bank branch is located. In most cases it is in line with the PIN code of the postal addresses in India. The next three digits stand for the bank code while the last three digits represent the bank branch code.
OMR-Optical Mark Reader
Optical mark recognition (also called optical mark reading and OMR) is the process of capturing human-marked data from document forms such as surveys and tests.
Many traditional OMR devices work with a dedicated scanner device that shines a beam of light onto the form paper. The contrasting reflectivity at predetermined positions on a page is then used to detect these marked areas because they reflect less light than the blank areas of the paper.
Some OMR devices use forms which are preprinted onto 'transoptic' paper and measure the amount of light which passes through the paper, thus a mark on either side of the paper will reduce the amount of light passing through the paper.

A joystick is an input device that can be used for controlling the movement of the cursor or a pointer in a computer device. The pointer/cursor movement is controlled by maneuvering a lever on the joystick. The input device is mostly used for gaming applications and, sometimes, in graphics applications. A joystick also can be helpful as an input device for people with movement disabilities.

Multi-user software is software that allows access by multiple users of a computer. Time-sharing systems are multi-user systems. Most batch processing systems for mainframe computers may also be considered "multi-user", to avoid leaving the CPU idle while it waits for I/O operations to complete.
