A double colon ( :: ) can replace any single, contiguous string of one or more 16-bit segments (hextets) which is consist of all 0s, and it can only be used once per IPv6 address. Therefore,any leading 0s (zeros) in any 16-bit section or hextet can be omitted.

D doesn't make much sense, it's valid, but not what we're looking for. B also has a correlation with D, same reasoning applies. As for A, it seems pretty legit, but I don't believe that's what we're looking for.
Choice C is the most obvious one though. We're talking about a network and as may or may not know it's a wireless one in a manner of speaking. A <span>couple of computers in the network that have trouble maintaining a signal will indefinitely lead to failure of a network since both the links and nodes of certain computer systems are incapable of maintaining a signal. </span>
The answer is Multitasking. NOS (Network Operating System) has the ability to execute more than one program at a time. It allows different programs to operate on the CPU, effectively giving each program a virtual copy of the CPU while preventing the program from directly manipulating the hardware. The NOS switches the CPU time from one task to another in order to create the idea that several tasks are being executed at the same time, but in reality, only one program is being executed.
