Layers of OSI Model

OSI stands for Open Systems Interconnection. It has been developed by ISO – ‘International Organization of Standardization‘, in the year 1984. It is a 7 layer architecture with each layer having specific functionality to perform. All these 7 layers work collaboratively to transmit the data from one person to another across the globe. In the OSI reference model,… Read More »

Transport Layer in OSI Model

Transport Layer is the second layer of the TCP/IP model. It is an end-to-end layer used to deliver messages to a host. It is termed as an end-to-end layer because it provides a point-to-point connection rather than hop-to- hop, between the source host and destination host to deliver the services reliably.

Goals and Applications of Networks

A network consists of two or more nodes (e.g. computers) that are linked in order to share resources (such as printers and CDs), exchange files, or allow electronic communications. The computers on a network may be linked through cables, telephone lines, radio waves, satellites, or infrared light beams. Networking Elements : The computer network includes the following networking… Read More »

Types of Network Topology

Network Topology is the representation of a network arrangement, consisting of several nodes i.e. sender and receiver nodes, and the lines connecting these nodes. Types of Network Topology : Let us look at the type of Network Topologies available. P2P Topology : Point-to-point topology is the easiest of all the network topologies. In this method, the network consists… Read More »
