Short for constant linear velocity, a method used by most older CD-ROM players to access data. With CLV, the rotation speed of the disk changes based on how close to the center of the disk the data is. For tracks near the center, the disk rotates faster, and for data on the outside, the disk rotates slower.
The purpose of CLV is to ensure a constant data rate regardless of where on the disk the data is being accessed. Because less data can fit on the inside tracks, the disk needs to rotate faster for these areas
An alternative technology, which is becoming increasingly popular, is CAV (Constant Angular Velocity).
Short for computer-mediated communication. CMC refers to human communication via computers and includes many different forms of synchronous, asynchronous or real-time interaction that humans have with each other using computers as tools to exchange text, images, audio and video. CMC includes e-mail, network communication, instant messaging, text messaging, hypertext, distance learning, Internet forums, USENET newsgroups, […]
Short for Common Management Information Protocol, and pronounced see-mip, an OSI standard protocol used with the Common Management Information Services (CMIS). CMIS defines a system of network management information services. CMIP was proposed as a replacement for the less sophisticated Simple Network Management Protocol (SNMP) but has not been widely adopted. CMIP provides improved security […]
Short for Computerized Maintenance Management Systems. A CMMS usually consists of hardware solution and a software package that allows an organization to manage the maintenance of equipment and facilities. Use of a CMMS package should improve productivity, lower overall operating costs, and store valuable information about maintenance functions in an organization. Computerized Maintenance Management Systems […]
Short for complementary metal oxide semiconductor. Pronounced see-moss, CMOS is a widely used type of semiconductor. CMOS semiconductors use both NMOS (negative polarity) and PMOS (positive polarity) circuits. Since only one of the circuit types is on at any given time, CMOS chips require less power than chips using just one type of transistor. This […]
(1) Short for content management system. (2) Short for color management system.
