Document Summary
Chapter 7: telecommunications, the internet, and wireless technology. Telephone networks and computer networks converging into single digital network using internet standards. More than 90% of canadian internet users have broadband access. Designates a single communications medium that can transmit multiple channels of data simultaneously. Voice, data communication are taking place over broadband wireless platforms. Major components in simple network (client and server computers, network interfaces (nics), connection medium, network operating system, hubs, switches, routers) Sdn (software-defined networking): functions of switches and routers managed by central program. 100 of local area networks (lans) linked to firm-wide corporate network. Various powerful servers (website, backend systems, external, intranet) A model for computing that splits processing between clients and servers on a network, assigning functions to the machine most able to perform the function. Clients linked through network controlled by network server computer. Technology that breaks messages into small, foxed bundles of data and routes them through any available communication channel.
