ATM Asynchronous Transfer Mode protocol. Baseband the primary signal characteristic in a network where only one carrier frequency is used (Ethernet is an example of a baseband network). Cable any or all of copper cable, fibre optic cable, coaxial cable. Coaxial cable includes 10Mbps baseband coaxial cable (Thinnet) (10Base-2) and 10Mbps baseband coaxial cable (Thicknet) (10Base-5) and cable suitable for radio frequencies and transmission purposes. Ethernet a process called carrier sense, multiple access, collision detection (CSMA/CD), which has data collision detection, it is used to pass data across a physical media. Industry practice those practices, which competent practitioners within the industry recognise as current industry best practice. Infrastructure includes but is not limited to Cable, Coaxial cable, Wireless. IP internet protocol. PCI peripheral connection interface.
