The physical perspective entails geographic areas, physical cabling, and the network components (e.g., routers, bridges and application layer gateways) that interconnect by way of the transmission media. Logical networks, referred to as, in the TCP/IP architecture, subnets, map onto a quantity of transmission media. For example, a common follow in a campus of buildings is to make a set of LAN cables in every constructing look like a standard subnet, using virtual LAN technology. Bandwidth in bit/s could refer to consumed bandwidth, comparable to achieved throughput or goodput, i.e., the typical price of profitable information switch via a communication path. The throughput is affected by technologies corresponding to bandwidth shaping, bandwidth administration, bandwidth throttling, bandwidth cap, bandwidth allocation , and so forth. A bit stream’s bandwidth is proportional to the average consumed sign bandwidth in hertz during a studied time interval.
