How an Ethernet Worked?
The operation of Ethernet can be explained in simple terms as follows:
Each computer on the Ethernet Network, also called as a node, operates independently of all other nodes. All nodes attached to an Ethernet are linked to a shared medium over which the Ethernet signals travel serially, one data bit at a time.
To send data a station first listens to the channel and when the channel is idle the station transmits its information in the form of an Ethernet frame, or packet. The Ethernet rules (protocol) are explained in such a way that each node gets a fair amount of frame transmission opportunity.
What is NOS? NOS, or Network Operating System, are specialized software whose major task is to give network connectivity to a computer in order for it to be able to converse wi
Linked List A linked list is a data structure composed of zero or extra nodes linked by pointers. Each node consists of two parts, as shown in Figure: info field having specifi
Q. Describe Physical Layer in OSI layers model? Physical Layer : Controls the transmission of the actual data onto the network. It describes the electrical signals, line state
Q. Show the Application Layer Responsibilities? - Make possible user access to the network - User interfaces as well as support for services such as E-Mail File
Sending a message to a group multicast address is known as multicasting, and its routing algorithm is known as multicast routing.
FCS= Frame Check Sequence CRC (Cyclic Redundancy Check) algorithm runs in switch that known as FCS (Frame Check Sequence)
How many types of twisted pair cable are there We can find two types of twisted pair cables, namely: Unshielded Twisted Pair Cable (UTP) and Shielded Twisted Pair Cable (STP).
Notice repetition of information in routing table for node 1 as given above in the figure. We can see that switch has only outgoing connection, all traffic must goes that connec
