7. Which of the following is the best type of module cohesion? Explanation: Functional Cohesion is a type of cohesion in which the tasks performed by a software module all contribute to the performance of a single function.

Cohesion is the measure of strength of the association of elements within a module. Modules whose elements are strongly and genuinely related to each other are desired. A module should be highly cohesive.

Coupling refers to the interdependencies between modules, while cohesion describes how related the functions within a single module are. Low cohesion implies that a given module performs tasks which are not very related to each other and hence can create problems as the module becomes large.

1. Which among the following best describes polymorphism? Explanation: It is actually the ability for a message / data to be processed in more than one form. The word polymorphism indicates many-forms.

Answer: COUPLING is the measure of the degree of Interpendence between modules.

Coupling between two modules is a measure of the degree of interdependence or interaction between the two modules. A module having high cohesion and low coupling is said to be functionally independent of other modules.

• 1- Functional Cohesion.
• 2- Layer Cohesion.
• 3- Communication Cohesion.
• 4- Sequential Cohesion.
• 5- Procedural Cohesion.
• 6- Temporal Cohesion.

Studies by various people including Larry Constantine, Edward Yourdon, and Steve McConnell indicate that the first two types of cohesion are inferior; communicational and sequential cohesion are very good; and functional cohesion is superior.

Cohesion means sticking together. If your group of friends heads to the lunchroom as a team and sits all together, you’re demonstrating strong cohesion. Cohesion is a word that comes to us through physics, where cohesion describes particles that are the same and tend to stick together — water molecules, for example.

Creating cohesion means ‘tying’ our words, phrases, sentences and paragraphs together, to create a text where the relationships between these elements is clear and logical to the reader, giving the text ‘flow’.

1 : the act or state of sticking together tightly especially : unity the lack of cohesion in the Party — The Times Literary Supplement (London) cohesion among soldiers in a unit. 2 : union between similar plant parts or organs.

Cohesive devices are words or phrases used to connect ideas between different parts of text. There are three main types of cohesive devices: Pronouns that refer back to a previously mentioned noun. Example: Jim went out to the playground.

A cohesive sentence must make sense. A cohesive sentence must flow with the sentences around it. A cohesive sentence must be coherent and fit with other sentences around it. Pronouns (I, you, he, she, it, we, they) must agree in cohesive sentences.

Cohesive devices tell the reader what we are doing in a sentence and help to guide them through our writing. They signal to the reader what the relationships are between the different clauses, sentences and paragraphs.

There are two cohesive devices in the sentences above: ‘and’ and ‘but’. Both give the reader different signals and change the meaning of the sentence.

Cohesion refers to the logical flow and connection in a written text and is achieved through the use of devices to link sentences together so that there is a logical flow between ideas from one sentence to the next. In academic writing paragraphs are essential to the structure of the text.

Repeated words/ideas Cohesion is an important feature of academic writing. It can help ensure that your writing coheres or ‘sticks together’, which will make it easier for the reader to follow the main ideas in your essay or report.

Coherence is an essential quality for good academic writing. In academic writing, the flow of ideas from one sentence to the next should be smooth and logical. Without cohesion, the reader will not understand the main points that you are trying to make. It also hampers readability.
