Explanation of transportation media or transmission media

Transportation media can be defined as the physical path to convey the information between sender and receiver.  In other words, the procedure of transmitting the data between two or more digital devices in analog-digital form. In a computer network, we make an effort towards a couple of things in which an important function is to … Read more

Comparison between OSI Model and TCP/IP Model

                  OSI reference model                          TCP/IP model OSI stands for Open system interconnection, and it is developed by the international standard organization (ISO). TCP/IP stands for Transmission control protocol/ internet protocol, and it is developed by the Department of defence (DOD). OSI is a general protocol self-reliant model. It behaves as a connection gateway between … Read more

Topology in Computer Network, Its advantage and disadvantage

Topology means the arrangement of the network in that way, all the constituents are interconnected to each other. In other words, the arrangement of nodes connected in a network by some physical medium such as optical fiber and cable. Network topology permits you to understand the dissimilar components of your network and the network’s connection.   … Read more

Which OSI layer performs the following activities:(a) Error detection and correction (b) Routing (c) Responsibility for delivery between adjacent nodes (d) Reliable process to process data transmission

(a) Error detection and correction: Data link layer performs the error detection and correction. The data link layer allows practical means to transmit data between the network and detect and correct the errors that may appear in the physical layer. (b) Routing: The network layer performs routing the data through the better physical path. (c) … Read more

Explanation of TCP/IP Protocol Layer with Diagram

There are four layer in TCP/IP Protocol 1. Application Layer The application layer is the topmost layer of the TCP/IP protocol. It also performs the role of the session layer and presentation layer in TCP/IP model.  This layer allows people to use the network services and establish network-based applications.  The protocols of this layer are … Read more
