Final answer:
The question pertains to deciding on a network type, the count of computers on the network, and the topology that best suits an office setup. Without additional information, it's challenging to make definitive selections for the network type and the number of computers. However, a star topology is generally a good fit for office settings.
Step-by-step explanation:
The question seems to be asking for an understanding of computer network types, the number of computers in a network, and the best network topology for an office setting. To determine whether the network will be peer-to-peer or server-based, we need more context about the network's intended use and required resources. Without this information, we cannot accurately choose between options a) Peer-to-peer or b) Server-based.As for the number of computers that will be attached to the network, there is no clear indication given in the question, so we cannot choose between the options of 25, 20, 45, or 50 computers.
Regarding the best topology for an office given the availability of wiring closets, usually, the star topology is a common choice as it allows for centralized management and easy maintenance. However, without specific information about the size of the office, the number of devices, and budget constraints, it's difficult to definitively state which topology (options a) Star, b) Bus, c) Ring, or d) Mesh) is the best fit.
