2. General nature of Computer programs.
Read or Write to computer memory.
Do operations on the data in the computer memory
Hand over the data to other parts of the program for more operations.

3. Functions
A computer program cannot do all the required actions by itself.
Instead it depends on function to delegate a particular job.
You can pass variables into function and return value from a function.
So function is a part of the program which can be “called” for a specific task to be done.
