Wide area network standards,A wide area network may be arbitrarily defined as a network which interconnects computers, terminals and local area networks at a national or international level. The most significant standards which apply to wide area networks are concerned with:Irrepressible 发表于 2025-3-25 14:22:50
Performance prediction,A point-to-point communication link may be procured with a fair amount of confidence that the link circuitry and protocol will meet the design objectives. To estimate the line throughput (number of information bits correctly received divided by the time taken for transmission) several factors must be taken into account including:Albinism 发表于 2025-3-25 16:52:20
Data communication concepts and alternatives,ive needles which pointed to the letters of the alphabet. The first machine to use serial binary data communication was the teleprinter, developed by Emil Baudot in 1874. The Baudot Code uses five bits to represent the letters of the alphabet and a figures shift character, after which code combinations are interpreted as numbers.斜坡 发表于 2025-3-25 22:56:31
Network topologies, switching and access control,viewed by the user as one large computer system which allocates jobs without user intervention. A computer communication network is viewed as a collection of several computer systems from which the user can select the service required and communicate with any computer as a local user.Self-Help-Group 发表于 2025-3-26 03:46:02
Layered network architectures,ols and logical structures for the functions which provide effective communication between data processing systems connected to the network. Layering separates the functions into distinct levels which communicate individually with like levels in distant nodes.PRISE 发表于 2025-3-26 08:03:49
