In Communication Networks External electromagnetic signals can cause incorrect delivery of data. By this, data in the communication Networks can be received incorrectly, data can be lost or unwanted Communication Networks data can be generated. Any of these problems are called transmission errors in communication networks.

Definition: Ethernet (pronounced "eether net") is a computer network technology which is used in different area networks like LAN, MAN, WAN. Ethernet connecting computers together with cable so the computers can share information. Within each main branch of the network, "Ethernet" can connect up to 1,024 personal computers and workstations.

What is Hub: Another name of Hub is Ethernet Hub, Repeater Hub, Active Hub and Network Hub. Basically, it is a similar to switch but are not as "smart", 

Hub Definition and Meaning

hub in computer network is used for connecting multiple computers or segments of a LAN. Normally, it is used for Peer to Peer small Home Network. LAN Hub receive data packets (frames) through one port and broadcasts them through all other ports, so that all other computers or other network devices can see all packets.

Digital communication networks have become a core technology in advanced building automation systems. Communication networks such as MS/TP, ARCNET, and Ethernet can be categorized as discrete-event dynamic systems (DEDS) (Casandras and Lafortune 1999).

Flooding is the static routing algorithm. In this algorithm, every incoming packet is sent on all outgoing lines except the line on which it has arrived.

One major problem of this algorithm is that it generates a large number of duplicate packets on the network.

The parity check method is used fro error detection. It is also known as VRC method.

(a) In this method, a redundant bit called parity bit is added to each data.

This advises the routers are used to connect dissimilar LANs and perform all the functions of bridges and routers. It operates at all seven layers of the OSI Reference Model. These are actually predecessors of router nowadays and are technology wise more expensive and highly functional. They in general consist of software which resides in a host computer, such as mid-range or mainframe.
