Answer:
Reference
Explanation:
Variables provide reference to the stored data value.
For example:
int i = 0;
Here i is a variable of type int with an initial value of 0. i is a reference to this stored value 0. Now if I want to update the data, I can do so using this reference.
i = 1;
Now the reference is used to manipulate the stored data and change it to 1. In a similar manner all updates to the value can be done using the variable reference.
Try restarting it. If you can’t restart because the screen is frozen maybe just turn it off and back on. If you already tried restarting and it still didn’t fix the problem, just give it some time. The computer will reset itself eventually which should fix the problem.

To make this link, the following protocol and the port number combinations must be enabled on the firewall of the remote connection.
Answer: E
All decision variables must be integer
Explanation:
The integer-linear program is a program in which the objective function and any constraints are all linear ie all of the variables are restricted to be integers.
A linear program is Np complete. Also every decision variable appear in any constraints must also appear in the objective function, possibly with zero coefficient if needed.
