Also, for serial transmission, some overhead time is needed since bits must be assembled and sent as a unit and then disassembled at the receiver. Serial transmission can be either synchronous or asynchronous. In synchronous transmission, groups of bits are combined into frames and frames are sent continuously with or without data to be transmitted.
Applications Serial transmission is between two computers or from a computer to an external device located some distance away. Parallel transmission either takes place within a computer system on a computer bus or to an external device located a close distance away.
A special computer chip known as a universal asynchronous receiver transmitter UART acts as the interface between the parallel transmission of the computer bus and the serial transmission of the serial port. UARTs differ in performance capabilities based on the amount of on-chip memory they possess. Examples Examples of parallel mode transmission include connections between a computer and a printer parallel printer port and cable.
Most printers are within 6 meters or 20 feet of the transmitting computer and the slight cost for extra wires is offset by the added speed gained through parallel transmission of data. Examples of serial mode transmission include connections between a computer and a modem using the RS protocol.
Although an RS cable can theoretically accommodate 25 wires, all but two of these wires are for overhead control signaling and not data transmission; the two data wires perform simple serial transmission in either direction. In this case, a computer may not be close to a modem, making the cost of parallel transmission prohibitive—thus speed of transmission may be considered less important than the economical advantage of serial transmission.

It is a system where a specific business focuses on routing and servicing calls for another business. Majority of the time, the telephone network is used around the world for recreational purposes.
Network structure[ edit ] In general, every telecommunications network conceptually consists of three parts, or planes so called because they can be thought of as being, and often are, separate overlay networks : The data plane also user plane, bearer plane, or forwarding plane carries the network's users' traffic, the actual payload.
The control plane carries control information also known as signaling. The management plane carries the operations and administration traffic required for network management.
The management plane is sometimes considered a part of the control plane. Data networks can be connected to allow users seamless access to resources that are hosted outside of the particular provider they are connected to. The Internet  is the best example of many data networks  from different organizations all operating under a single address space.
