There are six basic functions of IT.
1. Capture: Compiling detailed records of activities.
2. Processing: Converting, analyzing, computing and synthesizing all forms of data and information.
3. Generation: Organizing information into a useful form.
4. Storage: Retaining information for further use.
5. Retrieval: Locating and copying stored data or information for further processing or for transmission to another user.
6. Transmission: Distributing information over a communication network.
A computer uses unallocated space also know as free space to keep a file that has been deleted in its disk until a new file takes it spot and overwrites it.

The sum is 9237. To express this as binary requires log(9237)/log(2) bits ≈ 13.2 bits, rounded up at least 14 bits. (You can check: 2^13 is not enough, 2^14 is enough)
So you need four 4-bit adders, giving you 16 bits resolution.
Answer:
A) The type of data it will hold
Explanation:
In most programming languages, a variable must be decalared before it can be used. Variable declarations allows the compiller to make provision of memory space for the variable so the type of data must be defined accordingly with the name of the variable because different data types occuppy different spaces in memory for example
An integer is 32 bit integral value
A char is 16 bit unicode value
A double is 64 bit floating point value
