Types of communication network pdf

The best example is the communication between top level and bottom level employees. Miscommunication does not happen in this network as this is a type of direct communication. This network is in a hierarchical level and follows a series of commands. Here bottom to top communication does not happen. Superiors ordering the subordinates is the best example of this type of network. Also, the leader leading the group of people is an example of Chain Network. The message has to reach from top-level to bottom level without any alteration of meaning or words.

Care should be taken to avoid the same. When the communication between two people happens simultaneously in a circuit is called Circuit Network. Though it works like Vertical Network, there are no superiors or subordinates or at least not considered like them. Here the communication is a two-way communication. The messaging or information reception is continuous and the people involved can be at the same hierarchical level. The commands or information is from a single superior and subordinates form a wheel in the network.

The entire network is highly centralized format and expects immediate feedback once the message is given to the receiver. And due to this, we can call this communication as a type of micromanagement. This network is an improved form of Chain Network. Since the information is received directly from the central authority, there is no chance of miscommunication and the communication is very powerful.

Startups mostly use this type of network. Several people are involved in this network and the process forms a star shape. This network enables people to communicate with each other or with people who are involved in the same process.

This network can be considered as a development of a wheel network with no central person to control the way of communication. All are free to communicate with each other.

No restrictions are present to block the communication between people in the process. Teamwork is built using this communication. A WhatsApp group which is related to work is a good example of Star Network. The type of network to be used depends on the message to be passed from one level to another.

Nodes : A node is any device connected to a computer network and share the resources of the network. Server : A server is a computer designed to process requests and deliver data to other computers over a local network or the Internet. Two Types: a Non-dedicated : not completely dedicated to the cause of serving.

Signal repeater : collects the inbound packet and retransmits them. The set of request from browser to server. The set of response going back to the other way.

Internet, and how data should be transmitted between them. An application protocol such as mail. A protocol which provides services require by many applications such as TCP. IP for getting datagrams to their destinations.
