Broadband. High-speed data transfer connections. For residential users, broadband
connections are characterized by higher speeds than dial-up Internet access and are "always
on." They can be offered over a variety of fixed networks such as copper networks or fibre
optic networks, or over wireless networks such as WiMAX. For enterprise customers, in
addition to high-speed Internet connections, broadband can include Asynchronous Transfer
Mode or Frame Relay data connections that enable secure managed data services.

Broadcasting.
Broadcasting is a process that sends voice, data, or video signals
simultaneously to a group in a specific geographic area or to those connected to a broadcast
network system such as a satellite or cable television system. Broadcasting is typically
associated with radio and television.

•

Carrier Pre-Selection. Carrier pre-selection allows telephone subscribers to use a long
distance and international operator different from the provider of their telephone access,
thereby facilitating competition in those services. The long distance provider may bill the
subscriber directly or the incumbent may be required to bill the client for a fee.

CEO: Chief Executive Officer

•

Circuit Switched Network. A type of network in which a physical path is obtained for, and
dedicated to, a single connection between two end points in the network for the duration of the
connection. This connection is typically used for two-way transmissions such as telephone
calls or dial-up Internet access.

•

Commercial Broadcaster. A broadcaster that is funded solely from private means such as
sales and marketing, sponsorships, donations, and merchandising, but not from Government
means. Commercial broadcasters are autonomous from Government and have historically
operated with complete editorial freedom.

•

Communications Sector. This refers collectively to the telecommunications, broadcasting,
and postal sectors.
