What is an Algorithm?
An unambiguous set of steps, which when performed correctly by a processor, will result in a process being carried out in a finite time.

What two properties of the algorithm enable it to correctly describe the solution to the problem of making a cup of coffee?
The two properties of the algorithm is that it is specific and it is in the correct sequence.

Define Algorithms for the following processes.
