It depends on what you are doing in terms of "upgrading". The first question would be upgrading to what? Or simply extending the bus structure? Justification also consists of budgeting, costs, personnel training, and other factors.
Bus, Star and Ring come off the top of my head.
Bus topology is the most popular topology. Justify.
There are two basic categories of network topologies Physical topologies Logical topologies The shape of the cabling layout used to link devices is called the physical topology of the network. Logical topology is the way the signals act in the network In BUS topology you have "THE LINEAR BUS" and "THE DISTRIBUTED BUS" IN the LINEAR bus all the nodes of the network are connected to a common transmission medium which has 2 end points where as in the DISTRIBUTED, all the nodes are connected to a common transmission medium which has more than 2 end points.
According to my point of view, Bus topology is best for this organization because its inexpensive and the bus which can be used must be a high speed so it works well.
Only one.
"Network topology" refers to the physical and/or logical layout of the nodes in a computer network. Common network topologies include "bus" (ethernet, a lot of other networking specs) and "ring" (token ring, ATM).
Without knowing a bit more about the context, probably "topology".Common network topologies are ring, star, bus and mesh.
Bus
The NIC (network interface card) provides this interface.
The common network of bus topology is a network where clients are connected through cables called a bus. You can learn more about this at the Wikipedia. Once on the website, type "Bus network" into the search field at the top of the page and press enter to bring up the information.
i will answer the question
Start with your basic bus topology, where you have a beginning and an end of the network with however many nodes connected in series between. Now, add an identical bus network, except this time start from the other bus network's end and end at this other network's beginning. That's a dual bus topology. This simply provides a single, fail-safe mechanism to the normal bus topology.
