A reference model like OSI is frequently used in mode communication, which states that how the data is communicated between two software applications in the computer. This model comprises 7 layers where each layer has its own security protocols and responsibilities. This was developed in the year 1984 by ISO (International Organization for Standard) and today the model is defined as an architectural approach of inter-computer communications. As every layer in the OSI model is aligned with … [Read more...]
What is a Virtual LAN : Architecture & Its Types
These days, the communication network has been implemented with the growing technology. The communication between the computer networks is achieved very easily by dividing the networks into Local Area Networks (LANs) and Wide Area Networks (WANs). When all the physical devices of the network are connected to each other within the same network using a switch link, then it is called LAN. It is mainly used for official purposes. Similarly when the various networks with logical workstations are … [Read more...]
What is Network Simulation : Various Simulators & Tools
For almost every industrial and military application, there is the need of computer and communication networks and the requirement of these is progressing day-by-day. With these networks, one can expect enhanced service with perfect functional conditions. It is more crucial to know the network performance where it is used. Simulation is employed to demonstrate the final and exact outputs and activities of courses. As the network simulation has multiple advantages and applications, this article … [Read more...]
What is a Routing Algorithm & Its Types
In computer networks, the data is converted into packets to transfer from source to destination. For the transmission of data packets, the network layer decides the best path, through which the data is to be transmitted. The network layer provides datagram and virtual circuit services and also shows the best route to transfer the packets from source to destination. The network layers give routing protocol, which is a routing algorithm, that gives the best and least path through which data is … [Read more...]
What is a Computer Port : Types & Its Working
In computer hardware and networking, the computer port acts as an interface between the peripheral devices like speakers, printers, webcam, etc and computer. The port is a physical point, through which all the peripheral devices can be connected to the computer. This is used to transfer the information or signal between the computer to other devices. (Computer to computer). This article gives a brief note on the computer port and its types. What is a Port in the Computer/ Computer Port? A port … [Read more...]
