- Management information system (MIS)
- An MIS consists of five related components: hardware, software, people, procedures, and databases. The goal of management information systems is to enable managers to make better decisions by providing quality information.
- Local area network (LAN)
- A collection of personal computers within a small geographical area, connected by a network. All of the components are owned or controlled by one company.
- Mathematical model
- A model that is defined by mathematical equations. This format is easy to use for forecasts and for simulation analyses on the computer. Be careful not to confuse precision with accuracy. A model might forecast some value with great precision (e.g., 15.9371), but the accuracy could be quite less (e.g., actual values between 12 and 18).
- Magnetic hard drives
- Magnetic hard drives (or disk drives) consist of rigid platters that store data with magnetic particles. Data is accessed by spinning the platters and moving a drive head across the platters to access various tracks.
- Magnetic ink character recognition (MICR)
- A special typeface printed with ink containing magnetic ink. It can be read rapidly and reliably by computers. Banks are the primary users of MICR. Checks are imprinted with MICR routing numbers. MICR readers are more accurate than straight OCR because they pick up a stronger signal from magnetic particles in the ink.
- Legacy systems
- Information systems that were created over several years and are now crucial to operating the company. They probably use older technology, and the software is difficult to modify. However, replacing them is difficult and likely to interfere with day-to-day operations. Any changes or new systems must be able to work with the older components.
- Media
- For transmissions, the means of connecting computers in a network. Common methods include twisted-pair and coaxial cable, fiber optic lines; and radio, micro, and infrared waves.
- Materials requirements planning (MRP)
- An early production system, where at each stage of production, we evaluate the usage of materials to determine the optimal inventory levels.
- Manufacturing Resource Planning (MRP II)
- An integrated approach to manufacturing. Beginning with the desired production levels, we work backward to determine the processing time, materials, and labor needed at each step. These results generate schedules and inventory needs. Sometimes known as a demand-pull system.
- Mail filters
- Programs that automatically read e-mail and sort the messages according to whatever criteria the manager prefers. Junk mail can be discarded automatically.
- Mass customization
- The ability to modify the production line often enough to produce more variations of the main product. The goal is to cover virtually all of the niche markets.
