Explanation:
Answer:Less time invested in planning the network,
The use for fewer outlets, expansion in number of uplink ports
Explanation: A fixed-configuration switch is switch with a constant number of ports which can not be expanded.
Modular switches are switches whose number of ports can be expanded. Modular switches allows port expansion which gives it an advantage over fixed-configuration switch,with modular switches you spend less time in planning your work due to the availability of more ports needed to connect devices.
Modular switches doesn't require more power outlets unlike fixed-configuration switch where you need to connect different device on different power outlets.
Answer:
The last three options are the correct ones
Explanation:
The answer to the blank space in the given question is (C) conductors.
Conductors are<em> objects that can be used to make electrical current or heat flow from the source to a target object.</em> Some objects are better conductors than others due to its materials. For example, objects made from metals are always better conductors than objects made from wood or glass.
