Operation of verifying the identification of a person or a process. This is a security feature.
This is a standard connector used to connect IEEE 802.3 10Base-2 coaxial cables to Media
Access Unit (MAU).
This is a chip installed into a printed circuit board used to send executable boot commands
to a network device.
Stands Bits per second. Typically called bps. Refer to bit rate.
This device converts analog signals to digital signals in order to enable the Internet through
a cable network. Since telephone networks are made of copper wires and cable networks
are made of coaxial and optical cables, the bandwidth of cable networks are much wider
than that of telephone networks. However, the modulation/demodulation technology, which
converts digital to analog and vice versa, is required for cable networks when data is
transferred.
Call Center is a central place where calls from customers and other people are processed
systematically. Computer automation is implemented in Call Center to some degree.
Typically, Call Center processes many calls simultaneously, categorizes calls, connects the
calls to personnel, and records calling logs automatically. Call Center is typically used for
mail order catalog firms, telemarketing firms, customer centers for PC products, and large
enterprises that sell products or provide services.
Caller ID is a call service that enables the phone number of the caller to be sent to the
recipient. To see the phone number, a digital reader should be installed into the phone.
One of the five-level UTP cable connection methods specified by the EIA/TIA-586
standard. Category 5 cabling enables data to be transferred at a rate of up to 100Mbps.
Stands for Constant Bit Rate. The ATM network QoS class CBR defined by ATM Forum is
used for a connection device that is based on a precise clock processing method to ensure
untwisted data transfer.
Stands for Circuit Emulation Service. This service allows you to multiplex multiple line
emulation streams for voice and video with packet data through a single high-speed ATM
link without using a separate ATM access multiplexer.
This is a method for checking the integrity of transferred data. Checksum is an integer
calculated from the octet sequence obtained by a series of operations. This value is
calculated by the recipient again for verification.
This coaxial cable is made of an external cylinder-type conductor that wraps an internal
wire conductor. Examples of the coaxial cables used for LAN include 50Ω cables used for
digital signal processing and 75Ω cables used for high-speed digital signal processing.
