I need a clear explanation about the difference between project and program by example?

A project is a combination of different processes that is carefully planned and executed to achieve a certain goal. Example: SAP Implementation

A Program is a software that runs on a computer and example of it includes Web Browsers, email, video games 

thanks for the invitation

The project

It is the subject of the contract which is placed on implementation, obligations and duties between the two port project and the owner of the project conditions

The program (schedule)

Is a table showing the extent of implementation of the project and the stages of implementation and completion percentages of time to the other

Usually a "project" covers the intere procedure of a technical work, from concept design untill the built product. A program will usually refer to the design brief, or the construction schedule. For example, a project is a railway station, from conception to completion, while a program is only the procedure of gathering information on what specifications, a railway station, should cover.
