Answer 1

A module is a separate program designed to do a specific task and that you can import in your main program.

Answer 2

(1) In software, a module is a part of aprogram. Programs are composed of one or more independently developed modules that are not combined until the program is linked. A single modulecan contain one or several routines. (2) In hardware, a module is a self-contained component.

Modules are generic term. Works on Kiss principle. Keep it Simple Stupid.

Say for banking, you can different modules supporting different functionality-
Customer Information File.

Online General Ledger.

Deposits and Loans, including Loan Syndication.

24 x 7 availability.

Comprehensive Management Information System.

Trade Finance.

Budget and Expense Management.

Fixed Asset and Inventory Management.

Answer 3

A module can either be a class or method depending on what you trying to achieve.
Say in same example of bank, I can have different classes for Customer Info and Management Info to have separate data. Secondly, if I am doing some transactions with the bank - I can use different methods like through credit cards, netbanking, but achieve same objective.

Answer 4

So it can be a class or a method, that can be accessed by or executed by a main code??

Answer 5

Modules can be made generic or are they generic?? because from the first respose Pierre said they are separate programs that carry out specific operations, like a class or a method.
