1 backplane
"A circuit board or framework that supports other circuit boards, devices, and the interconnections among devices, and provides power and data signals to supported devices." -
2 chip-on-board
"A manufacturing technology that mounts an integrated circuit die directly to a circuit board. The die is electrically connected to the circuit board using wire bonding, and is then covered with a protective epoxy cover." -
3 COB

4 central processing unit
"The computational and control unit of a computer. The CPU is the device that interprets and executes instructions. Mainframes and early minicomputers contained circuit boards full of integrated circuits that implemented the CPU. Single-chip central processing units, called microprocessors, made possible personal computers and workstations." -

6 Voice over Internet Protocol
"The use of the Internet Protocol (IP) for transmitting voice communications. VoIP delivers digitized audio in packet form and can be used to transmit over intranets, extranets, and the Internet. It is essentially an inexpensive alternative to traditional telephone communication over the circuit-switched Public Switched Telephone Network (PSTN). VoIP covers computer-to-computer, computer-to-telephone, and telephone-based communications. For the sake of compatibility and interoperability, a group called the VoIP Forum promotes product development based on the ITU-T H.323 standard to transmit multimedia over the Internet."English-Arabic terms dictionary > Voice over Internet Protocol

10 clock
"The electronic circuit in a computer that generates a steady stream of timing pulses--the digital signals that synchronize every operation. The system clock signal is precisely set by a quartz crystal, typically at a specific frequency between 1 and 50 megahertz. The clock rate of a computer is one of the prime determinants of its overall processing speed, and it can go as high as the other components of the computer allow." -
11 transfer rate
"The rate at which a circuit or a communications channel transfers information from source to destination, as over a network or to and from a disk drive. Transfer rate is measured in units of information per unit of time -- for example, bits per second or characters per second -- and can be measured either as a raw rate, which is the maximum transfer speed, or as an average rate, which includes gaps between blocks of data as part of the transmission time." -
12 DIMM
A type of memory board comprised of RAM chips mounted on a circuit board with a 64-bit data path and pins on each side that are on different circuits and that respond to different signals. -
13 dual inline memory module
A type of memory board comprised of RAM chips mounted on a circuit board with a 64-bit data path and pins on each side that are on different circuits and that respond to different signals. -
14 matrix
"An arrangement of rows and columns used for organizing related items, such as numbers, dots, spreadsheet cells, or circuit elements." -
15 switch
"A circuit element that has two states, on and off." -
16 video digitizer
"A device used in computer graphics that uses a video camera, rather than a scan head, to capture a video image and then stores it in memory with the aid of a special-purpose circuit board." -
17 VoIP gateway
A computer device that converts between circuit switch telephony protocols and VoIP protocols. -
18 synchronous connection-oriented
"Pertaining to a Bluetooth data link type which is a symmetrical, circuit-switched, point-to-point connection between a master device and a subordinate device, primarily used for voice traffic."English-Arabic terms dictionary > synchronous connection-oriented
-
19 SCO
"Pertaining to a Bluetooth data link type which is a symmetrical, circuit-switched, point-to-point connection between a master device and a subordinate device, primarily used for voice traffic." -
20 T1
"A U.S. telephone standard for a transmission facility at digital signal level 1 (DS1) with 1.544 megabits per second in North America and 2.048 megabits per second in Europe. The bit rate is the equivalent bandwidth of approximately twenty-four 56-kilobits-per-second lines. A T1 circuit is capable of serving a minimum of 48 modems at 28.8 kilobits per second or 96 modems at 14.4 kilobits per second. T1 circuits are also used for voice telephone connections. A single T1 line carries 24 telephone connections with 24 telephone numbers. When it is used for voice transmission, a T1 connection must be split into 24 separate circuits."T1
