Algorithms

What is an Algorithm?
An unambiguous set of steps,which when preformed 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 sequence and selection properties enable it to correctly describe the solution of making a cup of coffee.
Define Algorithms for the following processes.
