Short for Electromagnetic Compatibility, EMC is the term used to describe how well a device or system is able to function in an electromagnetic environment without introducing electromagnetic disturbances that interfere with the operation of other electrical products in the environment. Electronic devices that can function and meet the criteria are called electro-magnetically compatible devices.

Data synchronization technologies are designed to synchronize a single set of data between two or more devices, automatically copying changes back and forth. For example, a user’s contact list on one mobile device can be synchronized with other mobile devices or computers. Data synchronization can be local synchronization where the device and computer are side-by-side […]

A system for ensuring that colors remain the same regardless of the device or medium used to display the colors. This is extremely difficult because different devices use different technologies and models to produce colors. In addition, color is highly subjective. The same colors look different to different people.

(1) When used to describe data storage, 1,024 kilobits. (2) When used to described data transfer rates, it refers to one million bits. Networks are often measured in megabits per second, abbreviated as Mbps.

A common problem that occurs when burning data into a CD. It happens when the computer is not supplying data quickly enough to the CD writer for it to record the data properly. Recording data to a CD-R is a real-time process that must run nonstop without interruption of the signal. A computer will typically […]

In computing terms, the word legacy is used to describe outdated or obsolete technology and equipment that is still being used by an individual or organization. Legacy implies that the system is out of date or in need of replacement, however it may be in good working order so the business or individual owner does […]

A circle shape that is divided equally in to 12 sections, with each section displaying a different color according to its pigment value. As all colors are created from the three primary colors (red, green and blue), the primary colors are shown forming a triangle within the color wheel. The color wheel shows the relationship […]

A setting on a digital camera that enables users to focus on subjects close to the camera lens. Macro mode is commonly used to photographing flowers, insects and other small items that you want a close-up view of. The distance you can shoot in macro mode from will differ between cameras. Some may be able […]

(1) Short for Data Link Control, the second lowest layer in the OSI Reference Model. Every network interface card (NIC) has a DLC address or DLC identifier (DLCI) that uniquely identifies the node on the network. Some network protocols, such as Ethernet and Token-Ring use the DLC addresses exclusively. Other protocols, such as TCP/IP, use […]

Short for optical mark recognition, the technology of electronically extracting intended data from marked fields, such as checkboxes and fill-infields, on printed forms. OMR technology scans a printed form and reads predefined positions and records where marks are made on the form. This technology is useful for applications in which large numbers of hand-filled forms […]
