Call Center 3n3c51

CALL CENTER A department within a company or a third-party organization that handles telephone sales and/or service. Inbound call centers, which take calls from the outside, use automatic call distributors (ACDs) to route calls to the appropriate agent. Outbound call centers use "predictive dialers," which make calls from a list, but ensure that a person has answered before switching the call to the next available agent (see predictive dialer). See ACD, cyberagent, CSR, zip tone, Web callback, cherrypicking, blended call center, Web-enabled call center, live overload, call center in a box, agent turnover and call center overflow.

Definition of: bandwidth (1) Capacity or time. Computer people sometimes use the term very broadly. For example, "there's not enough bandwidth around here to get the job done" means there's not enough extra time or people. Its true meaning follows. (2) The transmission capacity of an electronic pathway such as a communications line, computer bus or computer channel. In a digital line, it is measured in bits per second or bytes per second (see Mb/sec). In an analog channel or in a digital channel that is wrapped in a carrier frequency, bandwidth is the difference between the highest and lowest frequencies and is measured in Hertz (kHz, MHz, GHz). See traffic shaping, video bandwidth and bandwidth junkie.

Definition of: modem (MOdulator-DEModulator) Until the late 1990s, the term referred to a device that allows a computer or terminal to transmit data over a standard dial-up telephone line. Since the advent of cable and DSL connections, the term may also refer to high-speed broadband modems (see cable modem, DSL and cellular modem). This definition pertains only to dial-up modems, also known as "analog modems," which convert digital pulses from the computer to audio tones that analog telephone lines can carry, and vice versa. V.92 is the last dial-up standard, providing a data rate of 56 Kbps (see V.92).

New computers geared for home s may or may not have a built-in analog modem, while those targeted for the office typically do not. However, a modem can be added internally via a PCI card, or externally via a USB port. Like a Telephone A modem dials the line and answers the call. It performs the digital-to-analog and analogto-digital conversion while controlling transmission speed. Whatever the top speed, some number of lower speeds are also ed to accommodate old modems or negotiate downward on noisy lines. Over the years, speeds evolved from 300 bps to 56 Kbps. Error Correction and Compression Modems have built-in error correction (V.42) and data compression (V.42bis, MNP 5). On files that are already compressed, the hardware data compression adds little value, because it cannot make compressed files smaller. Modems also have automatic feature negotiation, which adjusts to the other modem's speed and hardware protocols. The Hayes Standard Most modems use the Hayes AT command set, which are machine instructions for modem control. The term modem has been used as a verb; for example, "I'll modem you later." See modem status signals and AT command set.
