Coincidental Cohesion (Least Required)
Coincidental Cohesion (Least Required)

Coincidental cohesion (Least Required) Functional cohesion. All elements contribute to the execution of one and only one problem-related task ; Focussed - strong, single-minded purpose ; No elements doing unrelated activities Examples of functional cohesive modules: Compute cosine of angle ; Read transaction record ; Assign seat to airline passenger; Sequential cohesion. Elements are involved ...

Communicational Cohesion
Communicational Cohesion

Presumably communication cohesion involves the use of open standard protocols and formats. e.g. HTTP, JSON, etc. ETA: Wikipedia says: Communicational cohesion is when parts of a module are grouped because they operate on the same data (e.g. a module which operates on the same record of information).

Essentially, cohesion and adhesion are the "stickiness" that water molecules have for each other and for other substances. You can see this in the picture to the right. The water drop is composed of water molecules that like to stick together, an example of the property of cohesion.

Examples
Examples

One example of adhesion is water climbing up a paper towel that has been dipped into a glass of water, and one example of cohesion is rain falling as drops from the sky. During adhesion, water is attracted to other substances, causing the positive and negative molecules of the water to be attracted to the paper.

Logical Cohesion
Logical Cohesion

Functional Cohesion : all elements contribute to a single, well-defined task, i.e. a function that performs exactly one operation get_engine_temperature(), add_sales_tax() (emphasis mine). I don't fully understand the definition of logical cohesion.

Meaning
Meaning

Cohesion of molecules causes drops to form in liquids (as when liquid mercury is poured on a piece of glass), and causes condensing water vapor to form the droplets that make clouds. Compare adhesion.

Procedural Cohesion
Procedural Cohesion

In Sequential cohesion, activities are related and output for current activities is input for next activity but in procedural cohesion activities are unrelated. Example for Sequential Cohesion : Let us take an example of getting data from database. Below will be steps for this task. 1.

Temporal Cohesion
Temporal Cohesion

Temporal cohesion is when parts of a module are grouped by when they are processed - the parts are processed at a particular time in program execution (e.g. a function which is called after catching an exception which closes open files, creates an error log, and notifies the user).
