  • Since the introduction of the personal computer in the early 1970s, businesses have found more uses and applications for technology in the workplace. With the introduction of local- area networks, file sharing, and print sharing in the 1980s, it became obvious that distributed computing was no longer a passing fad. By the 1990s, computers became less expensive, and innovations such as the Internet allowed everyone to connect to computer services worldwide. Computing services have become large and distributed.

  • Network management is the poor cousin of network design and implementation. All too often it is treated as an inconvenience by equipment manufacturers, or forgotten entirely. But the ability to manage network devices is fundamental to their utility, and a successful and functional network can only be built from equipment that can be easily managed and operated. Management refers to the ability to confi gure, control, operate, and diagnose equipment. Of course, no vendor ships devices that cannot be managed, but typically each is operated and controlled in a different way.

  • This diagram illustrates the Physical layer (Layer 1) of the OSI model. The Physical layer is responsible for the ultimate transmission of data over network communications media. It operates with data in the form of bits that are sent from the Physical layer of the sending (source) device and received at the Physical layer of the destination device. Ethernet cabling, Token Ring network technology and SCSI all function at the Physical layer of the OSI model. Hubs and other repeaters are standard network devices that function at the Physical layer.
