Answer:
Variable.
Explanation:
A placeholder for a piece of information that can change is called variable.
In Computer programming, a variable stores information which is passed from the location of the method call directly to the method that is called by the program.
For example, they can serve as a model for a function; when used as an input, such as for passing a value to a function and when used as an output, such as for retrieving a value from the same function.
Hence, when you create variables in a function, you can can set the values for their parameters.
For instance, to pass a class to a family of classes use the code;
\\parameter Name as Type (Keywords) = value;
\\procedure XorSwap (var a,b :integer) = "myvalue";
Answer:
The minimum number of bits necessary to address 8K words is 13.
Explanation:
You have the number of words to address that is 8000 words, a word is the smallest addressable memory unit.
8000 words can be addressed with 
units. Now you have to find the value of n that approximates to the number of words.
So you can see that 13 bits are needed to address 8K words.
