Ethernet is used in the OSI model at the data link and physical layers. It formed the basis for the IEEE 802.3 Standard. This standard helped to unify network and hardware development. Ethernet is a continually evolving standard, and the original version supported a data transmission rate of o...

The physical network topology deals with the actual connections like wires, cables, etc. and the arrangement of networking devices. you can say that it is the physical layout of devices, computers, and cables in the network. Logical Network Topology The logical network topology tells about how t...
Network architectureunderstood as the set of layers and layer protocols that constitute the communication system. Network architectures offer different ways of solving a critical issue when it comes to building a network: transfer data quickly and efficiently by the devices that make up the network. ...
Diagram showing the seven layers of the OSI model Why are network switches valuable? Switches are responsible for relaying information between different endpoints and offer a plethora of benefits: Switches form the majority ofnetwork devices in modern data networksand carry huge amounts of traffic in...
the setup and maintenance of physical connections of the devices, including wires, cables, and more in a computer network. On the other hand, logical network layout is a conceptual representation of how these devices operate and transmit data at different layers of abstraction in the computer ...
Routers have the inbuilt intelligence to route traffic in a big networking system by treating the sub-networks as an intact network. They have the capability to analyze the type of next link and hop connected with it which makes them superior to other layer-3 devices such as switch and bridg...
Learn about firewalls in networking, their functions and types, and how they protect your network from unauthorized access and cyber threats.
A set of cooperating network protocols is called aprotocol suite. The Transmission Control Protocol/Internet Protocol (TCP/IP) suite, which is typically used inclient-server models, includes numerous protocols across layers, such as the data, network, transport and application layers, working together...
Network Protocols: Basic Layers Network protocols are broken up into categories called layers. Discussing the various layers is beyond the scope of this lesson, but suffice it to say that the first layer is closest to the electrical components, like the network cable of a computer. The last la...
