What are the four things that all computers need configured in order to operate on a modern network?

A defult gateway

A subnet mask

An IP adress

A name server

Explanation:

The clearest definition of a network is that of a communications system, as it allows you to communicate with other users and share files and peripherals. In other words, it is a communications system that connects several units and allows them to exchange information.

Network means the interconnected set of autonomous computers.

It is said that two computers are interconnected, if they are able to exchange information. The connection does not need to be made through a copper wire, it can also be made through the use of lasers, microwaves and communication satellites.

In addition to the correct configuration you need 4 essential elements:  an IP Address, the subnet mask for the local network, a primary gateway, and a name server.

none because it's so obvious

solution:

this situation is called an ip conflict.

data from a server is sent in small bits called packets. in an ip conflict, some packets will end up in one computer while some other packets will end up in another computer.

so…overall none of the computers get the data as the original message or picture being sent by the server cannot be retrieved with only half the packets. so it will show up as an error.

thus the final answer is d.
