  A   telecommunications network   is a group of   nodes   interconnected by   links   that are used to exchange messages between the nodes. The links may use a variety of technologies based on the methodologies of   circuit switching ,   message switching , or   packet switching , to pass messages and signals. Multiple nodes may cooperate to pass the message from an originating node to the destination node, via multiple network hops. For this routing function, each node in the network is assigned a network address for identification and locating it on the network. The collection of addresses in the network is called the address space of the network. Examples of telecommunications networks include computer networks, the Internet, the public switched telephone network (PSTN), the global Telex network, the aeronautical ACARS network, and the wireless radio network...

  What is Topology ? Topology defines the structure of the network of how all the components are interconnected to each other. There are two types of topology: physical and logical topology. Physical topology is the geometric representation of all the nodes in a network. The bus topology is designed in such a way that all the stations are connected through a single cable known as a backbone cable. Each node is either connected to the backbone cable by drop cable or directly connected to the backbone cable. When a node wants to send a message over the network, it puts a message over the network. All the stations available in the network will receive the message whether it has been addressed or not. The bus topology is mainly used in 802.3 (ethernet) and 802.4 standard networks. The configuration of a bus topology is quite simpler as compared to other topologies. The backbone cable is considered as a  "single lane"  through which the message is broadcast...

 Introduction to networking Definition :- Computer network is a group of Inter-connected computer aur collection of hardware component and computer inter-connected by communication channels lof resources and information.A Network consider of two or more PCs connected together for the purpose of sharing data,resources,hardware it is called as networking. Explain different types of characteristics of computor networking .    Cost :- cost includes the cost of the network component installation and their maintenance.    Reliability :-  Reliability defines the reliability of the network component and the connectivity between them. Security :- Security includes The protection of the network component and the data Content or the data transmit between them. Speed :-  Include of how fast data is transmitted between network and points. Scalability :- scalability Define how will the network can adopt to new  new growth, includes new user, application, and...
