In the given excerpt, Singh gives an example of how viruses are planted and used to spy/ get access to other people's computers. But while it is possible to get the main point of the example, it would have been better if the writer includes experience with a computer virus so that readers will find it easier to connect with the given example. This will enable them to better understand the working of viruses and their effects.

Thus, the correct answer is the first option.

The application layer process that sends mail uses Simple Mail Transfer Protocol (SMTP). When a client sends email, the client process connects with a server process on well-known port 25. A client retrieves email, however, using one of two application layer protocols: Post Office Protocol (POP) or Internet Message Access Protocol (IMAP). With POP, mail is downloaded from the server to the client and then deleted on the server. The server starts the POP service by passively listening on TCP port 110 for client connection requests. However, when a client connects to a server running IMAP, copies of the messages are downloaded to the client applications. The original messages are kept on the server until they are manually deleted.

How are the waterfall and agile methods of software development similar?

Both methods allow project teams to complete small portions of the entire project in small sprints and work on different steps simultaneously.

Both methods focus on development rather than planning, in order for project teams to work more quickly.

Both methods have project teams work on one step at a time and move on when the previous step is completed and approved.

Both methods require documentation so project teams stay on track and keep control over what version of the project they are working on.

In point 1, Both method, it divides the project into small parts, at it the working is easy, that's why it is correct. In point 4, Both method, it requires the documentation, that's why it tracks the project. In point 2 and 3, both were wrong because it focuses on both development and planning, and in Waterfall when one part is complete then it will go on the next part, but in the Agile, it does not use this technique.

Answers

Answer:

The statement to this question can be defined as follows:

*strike_Counter =*strike_Counter +22;//adds  value 22 in *strike_Counter

Explanation:

In the given question, it is already defined, that "strike_Counter" is an integer pointer variable, which means, it only holds the integer value in its address memory.

In the next step, it is defined, that it adds the value "22" in its variable, and for this, we declare the statement in the answer section, which adds the value.  

for example, if in the "strike_Counter" variable holds the integer value, that is 5 and after adding the 22 it will become 27.
