(ē´kw&l er´&r rāt) (n.) Abbreviated as EER. A biometric security system predetermines the threshold values for its false acceptance rate and its false rejection rate, and when the rates are equal, the common value is referred to as the equal error rate. The value indicates that the proportion of false acceptances is equal to the proportion of false rejections. The lower the equal error rate value, the higher the accuracy of the biometric system.
Also referred to as crossover rate or crossover error rate (CER).
Abbreviated as EQ, in audio processing, equalization is the process of modifying the frequency of a sound. Equalization is most commonly used to correct signals that sound unnatural. For example, if a sound was recorded in a room that accentuates high frequencies, an equalizer can reduce those frequencies to a more normal level.
- equipment footprint
In data center terminology, the equipment footprint refers to the physical area that is occupied only by data center equipment. It would not include areas such as aisles between racks and any space left at end of equipment rows.
- erasable optical disk
A type of optical disk that can be erased and loaded with new data. In contrast, most optical disks, called CD-ROMs, are read-only.
- ergonomic mouse
A type of mouse that has been designed to reduce muscle strain and decrease discomfort (while using the mouse) associated with a injuries such as carpal tunnel syndrome, arthritis, and tendonitis. Compared to other mice, an ergonomic mouse is designed to fit a more natural hand position when being used.
The science concerned with designing safe and comfortable machines for humans. For example, one branch of ergonomics deals with designing furniture that avoids causing backaches and muscle cramps. In the computer field, ergonomics plays an important role in the design of monitors and keyboards. Another term for ergonomics is human engineering.
