Answer: A. Voice over Internet Protocol

B. It reduces the delay for all objects requested by a user.

Explanation:

Voice over Internet Protocol is used to transfer voice communication and multimedia over the internet. It converts voice into a digital signal, transfers it over the internet and then reconverts it to voice when it reaches its destination.

Web Caching stores the data from a web page for reuse at a later time, this helps to reduce the tasks the server carries out and reduces delay. Because some objects are cached, more resources can be focused on objects that are not thereby reducing delay for all objects requested by a user.

CaHeK987 [17]

Answer:

True.

Explanation:

The statement written in the question is True.We can use one memory location and use it with different values.

For example:- When we are using a loop be it for,while or do-while.The counter that we use for iteration is one and we use that counter to run the loop.We are using a single memory location and we are updating the count in that memory location many times.

for(int i=0;i<1000;i++)

{

     //body.

}

We are using i's memory location and changing it 1000 times.
