Protocol. Like TCP/IP or HTTP etc
Answer:
D. method, class, generalization/specialization
Explanation:
The Cohesion is said to be the level to what an element of a module is related to others. Generally, the cohesion can be understood as an internal adhesive that holds together the modules. If the software is good then it is going to have high cohesion. Method and class are type of cohesion, as they hold the modules together. And generalization/specialization also is a general type of cohesion as generalization tracks the common features among the class, and binds them into one superclass. However, the specialization means creating subclasses out of the classes, and which is the meaning of the specialization. In an ideal situation, there should be high cohesion or single responsibility. However, in the case of inheritance, there can be multiple responsibilities. And hence composition like a generalization, specialization, association, aggregation are used to make use of the composition for reuse rather than inheritance. Have you seen language supporting multiple inheritances. You will never see it though there is some way. And its never allowed to ensure high cohesion. And hence three general types of cohesion are method, class and generalization/specialization. And this is option D.
Answer:
Option A is correct
Digital Subscriber line is a way where telephone companies provide internet access for connection.
It is a communication medium used to transfer digital signals. DSL is one of the most popular broadband internet access.
Explanation:
DSL stands for Digital Subscriber Line. DSL works with high-speed bandwidth that connects from a phone jack to a telephone network. DSL works within frequencies. You can use the DSL while making phone calls.
The answer is user EXEC mode. This is for setting, viewing, and testing system processes. In common, the user EXEC commands let you to link to remote devices, modify terminal line settings on a temporary basis, perform basic tests, and list system information. This also used by common system administrators, while the privileged EXEC mode is used by the root administrator. Use the enable and disable instructions to shift between the two levels. Access to the user-level EXEC command line needs a valid password.
