Cohesion of a single module/component is the degree to which its responsibilities form a meaningful unit; higher cohesion is better.
Coupling between modules/components is their degree of mutual interdependence; lower coupling is better.
A first-order principle of software architecture is to increase cohesion and reduce coupling.
Additional information can be found at the link I added below.
Coupling and cohesion are often used as opposite ends of a scale in measuring how "good" a piece of software is. They are very common metrics for measuring the quality of object-oriented code.
Cohesion describes how "focused" a piece of software is. A highly-cohesive system is one in which all procedures in a given module work together towards some end goal. High cohesion is often characterized by high readability and maintainability.
Coupling describes how reliant a given piece of software is on other modules. A highly coupled system in one in which the procedures in one module can directly access elements of another module. A low coupled system in one in which the procedures of one module can only interact with the procedures of another through an interface channel. Highly coupled systems are often characterized by code that is difficult to read and maintain (the reason cohesion and coupling are often used as opposites).
If you know what UML diagrams look like, then you can think of a highly coupled system as one in which there are multiple arrows pointing away from and into each module in the diagram.
What the difference between envelop and coherent detection of AM signals
The main difference between coherent and incoherent machine is the consistency in performance. A coherent machine has processors that work in a consistent manner.Ê
1) This is an example of coherent communication. 2) Of example this communication an is noncoherent.
COHERENT WAVESWhen the light waves are emitted from a single source and they have the zero phase difference between them then the waves are said to be coherent. The coherent waves are shown below:
Adhesive forces are the attraction between different substances, while cohesive forces are the attraction between molecules of the same substance.
In case of coherent demodulation carrier used for demodulation purpose is in phase and frequency synchronism with carrier used for modulation purpose. For non-coherent demodulation it is not in synchronism.
Coherent sources are sources of waves that have a constant phase difference between them. An example of coherent sources is two identical lasers emitting light waves with the same frequency and wavelength.
number one u cant spell difference
Cohesive forces are the attraction between molecules of the same substance, while adhesive forces are the attraction between molecules of different substances. In materials, cohesive forces hold the molecules of the material together, while adhesive forces allow the material to stick to other surfaces.
