What is difference between source programm and an abject module?

Source code is the "source" of a program. This means that this is the code provided by a programmer in a human readable and modifiable form. When a programmer writes a program, he/she will develop source code in a programming language such as C, C++, maybe Pascal among others.
An object module can mean two different things depending on the context. An object module generally is an intermediate step between source code and an executable file like a .EXE on Windows. An executable file is actually what is generated by a compiler (like GCC or Visual C++) from source code and is effectively "machine language". It is not human readable and to a certain extend is not even machine readable as a whole. The way it works is that part of an executable file contains information to tell the operating system how to read the file into memory and where to start running it. The operating system will then tell the CPU where to start reading the program while it is in memory. The executable is a series of instructions understandable by the CPU and it performs them one by one as the program defines. Consider this overall process of compiling as someone writing a recipe for a certain type of food and then another person will compile a list of instructions in way that a resturant kitchen staff can follow it over and over. A different compiler might even translate the recipe to a different spoken language. In a similar fashion, one compiler might translate from C to Intel x86 while another would translate to IBM PowerPC.
An object file often is an intermediate step between source and executable. This file is the result of compiling a single source file as opposed to all the source files of an entire program. Some programs fit in a single source file, but others can be hundreds or even thousands of source files. To compile the Linux kernel in it's full form as a single static executable can require compiling tens of thousands of files. Once each file is mostly translated to machine language and stored as an object file, a program called a linker is used to merge those files together into a single executable. This process might be seems as taking the recipe for and English muffin, another for hollandaise sauce and a final one for Eggs Benedict and merging all the steps together into a single recipe which a kitchen staff can execute in a given order to start with raw ingredients and produce the final product.

What is the difference between module and software components?
This depends somewhat on the methodology you are using. They may actually be just different names for the same thing.
What is photo interrupter module?
A photo interrupter module for a smoke alarm has a gallium-arsenide infrared LED and silicon phototransistor that is contained in a plastic housing. When smoke interrupts the slot between the receiver and sender, the module is switched on.
How many cotton bales are in a module?
The average KBH module builder can hold between 14 to 16 bales depending on the amount of compression and the overall weight of the cotton.
How are coupling and cohesion related to modular design?
Ideally, modules will have low coupling and high cohesion. Coupling describes the strength of the connection between modules in a program. Loose (or low) coupling occurs when modules do not depend on other modules. One way to control this is by avoiding the use of global variables and reducing the number of variables that are passed between the modules. Another is to limit the depth of module calls (where a module calls another module, that then calls another module, and so on). Cohesion is a measure of how well a module accomplishes the module's purpose. High cohesion implies that all the module's internal statements serve to perform the module's (single) task. In order for modules to work together, there must be some connection between them. The nature of the connection is important because it determines the extent to which the modules are coupled. How are they connected? The best way to connect them is to pass the value of a local variable in one module to a second module through its parameter list. (A local variable is a variable that is defined within a module (not a parameter) is local to that module. The values of local variables are not available outside of the module in which they are declared unless they are passed. Local variables are reset to their default values once control leaves the module in which they are declared.) Another way to share information is through the use of global variables. (A variable that is defined outside of a module and that does not need to be passed to a module to be accessed by it is a global variable. Global variables retain their value once control leaves the module in which they are referenced. ) Because the value of a global variable can be changed by any module without passing, it increases the coupling between modules.
Difference between module testing and unit testing?
unit tests are a collection of tests written by a developer during the software development process. Module tests are a collection of tests written by a tester after some code has been written by a developer.

What is the difference between PC-5300u and pc5300f?
The difference is the number of pins per module and to differentiate, the notch is placed in a different position.

The offset is usually the difference between the address of a module and the specific location being referenced.
What is the difference between make and compile in c?
make is a utility program, compile means translation from source to object module.
What is the difference between stub and driver?
Stub means a Dummy model of a particular module.Suppose we have to test the interface between 2 modules A and B and we have developed only module A while Module B is yet in development stage.So in such case we can not test module A but, if we prepare a dummy module, having similar features like B then using that we can test module A.Our main aim in this is to test Module A & not Module B so that we can save time otherwise we have to wait till the module B is actually developed.Hence this dummy module B is called as Stub.Now module B cannot send/receive data from module A directly/automatically so, in such case we have to transfer data from one module to another module by some external features. This external feature used is called Driver.At a time both stub and driver are essential.Please refer to below link for understanding difference between Stub & Driver:http://www.guru99.com/integration-testing.htmlThanks,Fahim

In vb6.0 difference between bas file and cls file?
Deciding between a standard module and a class module is not a decision based on performance, but one of design. The main difference between the two is in the way that they handle data. A standard module stores only one copy of the data. A class module encapsulates the data within each instance of the class. That is, for each instance of the class, the data exists separately. The other main difference is the scope of variables and procedures within the module. In general, any variables and procedures declared as Public within a standard module are visible anywhere in the project or external programs if the standard module is in a component. Variables and procedures declared as Public within a class module can only be seen through a reference to an instance of the class module. The lifetime of data and procedures stored within a module is affected by which type of module is used. The lifetime of the data and procedures in a class module is defined by the lifetime of the object. So data and procedures are available only if a reference to the object exists. Data and procedures declared within standard modules are available for the lifetime of the program. Therefore, to answer your question, if you are writing a function that you want available throughout the lifetime of the program and visible to all code in the application, then place the function within a standard module.
What is the difference between body control module and instrument panel cluster?
The difference between a body control module and a instrument panel cluster is that the instrument panel cluster is used for driver information through the means of gauge's, indicator lamps, and is generally an output. A body control module has inputs and outputs and has control features that allow it to switch and operate other vehicle options as lighting, retained power, horns, security options, etc.. The body control module can also operate relays and switches to have necessary components operate for other module systems as anti lock brakes and power train control modules.
