Network Topolgies
What is Topology? In the world of computer technology, the term that refers to the diagramming of connected devices within a network is called “topology”. To phrase it up, “topology” is the structure, layout or shape of the various devices contained in a network. There are various kinds of topologies but the three most common topologies are the bus, the ring, and the star. The bus topology is often mistaken as something else. Bus networks

Network Topoligies
Network Topologies A ring topology is like light bulbs in series with each other. If one or more computers are turned off, some of the computers connected to it in the network will not have access to the rest of the network or the internet. In other words, they will be isolated from the rest of the network. They will only work in full or 100% capacity when all computers are connected and turned on.

Network Topologies
A network topology is referring to the way the computers of a network are connected. Topologies are designed for specific tasks. The type of topology used is based on how many and what type of equipment is to be used. The type of applications that will be used and the rate of the transfer of data will need to be known as well. Response time requirements and the cost are also considerations when the choice

Network Topologies
Mesh, Bus, Ring and Star topologies The term Topology refers to the physical or logical shape or layout of a network. Communication between different nodes within a network is determined by its topology. Mesh, Bus, Ring and Star are four of the most common network topologies, each with advantages and disadvantages in relation to each other. Mesh Topology The Mesh topology is true to its name in that there are multiple redundant interconnections between network

Network Topologies
Network Topologies There are several different common topologies available in networking: Bus, Ring, and Star to name a few. A network topology is how computers, printers, and other devices are connected over a network. It describes the layout of wires, devices, and routing paths. With some many advances in technology and the networking of computers it is easy to forget that networking was not always smooth process. The bus topology was fairly popular in the
