Total lines (active and connected)

Money received by a firm as a result of its operating activities, investment activities, and financing activities.

Money paid out by a firm as a result of its operating activities, investment activities, and financing activities.

Computer tomography scanners (CT or CAT scanner) is an x-ray machine which combines many x-ray images with the aid of a computer to generate cross-sectional views and, if needed, three-dimensional images of the internal organs and structures of the body.

Users of portable telephones subscribing to an automatic public mobile telephone service which provides access to the Public Switched Telephone Network (PSTN) using cellular technology.

A terrestrial radio-based service providing two-way communications by dividing the serving area into a regular pattern of sub-areas or cells, each with a base station having a low-power transmitter and receiver. Although cellular radio is primarily a means of providing mobile telephone service, it is also used to provide data services and private voice services, and as an alternative to fixed wired telephone service where this is scarce, such as in developing countries.

A processor which controls and coordinates the processing of traffic in an exchange.

A platform describes some sort of hardware architecture or software framework (including application frameworks), that allows software to run. Typical platforms include a computer's architecture, operating system, programming languages and related runtime libraries or graphical user interface.

Nurtures careers of excellence and leadership in science and technology for academically talented high school and college students.

A team of people that promote collaboration and using best practices around a specific focus area to drive business results. This team could be staffed with full- or part-time members.

Used by a party providing certification services to those who wish to use a digital signature to facilitate on-line communication and transaction. A certification authority verifies the identity of a subscriber, issues a certificate linking the person to a particular public key, and publishes the certificate, which can be checked by those who want to verify a digitally signed electronic communication.

Consists of a code that pairs each character from a given repertoire with something else, such as a sequence of natural numbers, octets or electrical pulses, in order to facilitate the transmission of data (generally numbers and/or text) through telecommunication networks or storage of text in computers.

A virtual space where a chat session takes place. Technically, it is just the real-time communication between two computer users, such that once a chat has been initiated, either user can type in information and the entered text appears on the other user’s screen.

The encrypted form of data.

Establishes a dedicated physical connection between end points for the duration of that communication session.

Denotes the transfer of an individual set of bits within a TDM time-slot over a connection between an input port and an output port within a given circuit-switching node through the circuit-switching fabric.

Is a second-level Cisco Career certification that indicates a foundation in apprentice knowledge of networking. CCNA certification validates the ability to install, configure, operate, and troubleshoot medium-size routed and switched networks, including implementation and verification of connections to remote sites in a WAN

Related to network technology, is a 3 bit field within an Ethernet frame header when using 802.1Q tagging. The field specifies a priority value of between 0 and 7 inclusive that can be used by Quality of Service (QoS) disciplines to differentiate traffic. While CoS operates only on Ethernet at the data link layer, other QoS mechanisms (such as DiffServ) operate at the network layer and higher. Others operate on other physical layer.

Telecommunications network used for a specific purpose, such as a payment system, and to which access is restricted.

The use of video cameras to transmit a signal to a specific place, on a limited set of monitors.

Cluster is a grouping of content delivery processing entities with their related control entity. Such grouping allows the sharing of resources (e.g., storage capacity) based on provider's policy (e.g., taking into account parameters such as user location).

The art of recovering original data (the plaintext) that has been encrypted (turned into ciphertext) without having access to the correct key used in the encryption process. When new encryption algorithms are introduced, cryptanalysis determines how hard it is to break the code.

A method whereby many radios use the same frequency, but each one has a unique code. GPS uses CDMA techniques with codes for their unique cross-correlation properties.

A spread spectrum air interface technology used in some digital cellular, personal communications services and other wireless networks.

Identifies a set of characters that are relevant and should be identifiable for some Character Set. It does not, however, specify the actual encoding of these characters, which is done by one or more CESs.

Cybercrime is criminal activity done using computers and the Internet. This includes anything from downloading illegal music files to stealing millions of dollars from online bank accounts. Cybercrime also includes non-monetary offenses, such as creating and distributing viruses on other computers or posting confidential business information on the Internet.
