Hubs are now largely obsolete, having been replaced by network switches except in very old installations or specialized applications. Repeater hubs also participate in collision detection, forwarding a jam signal to all ports if it detects a collision. A hub works at the physical layer (layer 1) of the OSI model. It has multiple input/output (I/O) ports, in which a signal introduced at the input of any port appears at the output of every port except the original incoming. Repeater hub: for connecting multiple Ethernet devices together and making them act as a single network segment. Repeater: an electronic device that receives a signal and retransmits it at a higher level or higher power, or onto the other side of an obstruction, so that the signal can cover longer distances. Computer network can use the alternative source for the data communication. Bridge: a device that connects multiple network segments. This problem can be overcome by using the routing or switching devices. For data communication to occur, the communication device must be a part of a communication system. The transmitter transforms and encodes the data in such a form to produce electromagnetic waves or signals. Unlike less advanced network hubs, a network switch forwards data only to one or multiple devices that need to receive it, rather than broadcasting the same data out of each of its ports. For example: communication between a computer, server and telephone (through modem). Switch: a device that connects devices together on a computer network, by using packet switching to receive, process and forward data to the destination device. A data packet is typically forwarded from one router to another through the networks that constitute the internetwork until it reaches its destination node. social networking sites) Constraints and Sampling Huge amount of data and limited time. #Data communication and computer networking in hindi pdf pdf

Router: a networking device that forwards data packets between computer networks. Gateway: an interface providing a compatibility between networks by converting transmission speeds, protocols, codes, or security measures. Data communication is said to be local if communicating devices are in. Core network components interconnect other network components. Data communication refers to the exchange of data between a source and a receiver.
