16. Which of the following is true about function return statements? A) A function can hold multiple return statements, but only one return statement executes in one function call. B) A function can hold only one return statement. C) A function can hold multiple return statements, and multiple return statements can execute in one function call. D) A function can have maximum of two return statements.
Answer:
A) A function can hold multiple return statements, but only one return statement executes in one function call
Explanation:
This is because each function can only return one value, whether it be an integer, String, or other object.
However, you can have a series of if-else statements, or case statements, to return a different value depending on information (within parameters, or variables.
Excellent. So, you can have multiple return statements, but the function will only end up executing one of these return statements and return a single value.
Hope this helps!
The statement "When there are multiple return statements but one return statement should execute the 1 function call" is true.
The following information should be considered:
This can be done as every function has only a return i.e. one value. It can be an integer, string, or any other thing. The function can't hold only 1 return statement.The function can't hold many return statements that execute one function call. The function can't have the utmost 2 return statements.Therefore, we can conclude that option A is correct.

why is computer virus called destructive program
Answer:
A computer virus is a malicious software program loaded onto a user’s computer without the user’s knowledge and performs malicious actions.
Viruses which are the most commonly-known form of malware and potentially the most destructive. A virus can do anything from erasing the data on a computer to hijacking a computer to attack other systems, send spam, or host and share illegal content.
Explanation:
The term 'computer virus' was first formally defined by Fred Cohen in 1983. Computer viruses never occur naturally because they are always induced by people. Once created and released, however, their diffusion is not directly under human control. After entering a computer, a virus attaches itself to another program in such a way that execution of the host program triggers the action of the virus simultaneously. It can self-replicate, inserting itself onto other programs or files, infecting them in the process. Not all computer viruses are destructive though. However, most of them perform actions that are malicious in nature, such as destroying data. Some viruses wreak havoc as soon as their code is executed, while others lie dormant until a particular event (as programmed) gets initiated, that causes their code to run in the computer. Viruses spread when the software or documents they get attached to are transferred from one computer to another using a network, a disk, file sharing methods, or through infected email attachments. Some viruses use different stealth strategies to avoid their detection from anti-virus software. Some old viruses make sure that the "last modified" date of a host file stays the same when they infect the file.

Greg has a list of payments for goods brought every month for the years 2009,2010,2011, and 2012. He needs information from only the last three years. He can filter this by clicking on
Answer:
"2009" and clicking "does not equal 2009"
Explanation:
The operator, 'does not equal', is a filtering operator used to exclude a specified attribute. The 'does not equal' operator is also used to provide the definition of the condition of the filter given that there are different values of two attributes
Therefore, given that there are only four years, and Greg needs the information of the last three years, which are, 2010, 2011, and 2012, the information for the year 2009 is to be excluded
Therefore, the correct option is; "2009" and clicking "does not equal 2009"

Programming languages create codes that represent binary numbers so that programmers can write in a language closer to natural speech.
Answer:
True
Explanation:
A software can be defined as a set of executable instructions (codes) or collection of data that is used typically to instruct a computer how to perform a specific task and to solve a particular problem.
This ultimately implies that, programming languages are designed and developed for creating codes that represent binary numbers (0s and 1s), so that programmers or software developers can write in a language closer to natural speech i.e the human language.

Scalability should be considered very early in the project.
The cloud offers services to automatically scale your system and balance the workload between components.
An example of vertical scaling is adding a new server to the network.
Answer:
Horizontal scaling has fewer limits than vertical scaling.
The cloud offers services to automatically scale your system and balance the workload between components.
Scalability should be considered very early in the project.
Explanation:
Hope this helps :) If not, please let me know what answers are wrong
The statements that is true about scalability are:
The clouds provide resources to scale the system and balance the workload between components Scalability should be considered at the beginning of the project.Horizontal scaling has fewer limits than vertical scaling.Horizontal scaling is a type of scaling by adding more machines to your po of resources.
It is also called adding more power.
The difference between scaling up and scaling out is that horizontal scaling simply adds more machine resources to your existing machine infrastructure.
Vertical scaling is simply known to adds power to your existing machine infrastructure by increasing power from CPU or RAM to existing machines.
Conclusively, Scalability part of a system that handle a growing amount of work by adding resources to the system.

It is the way to convey a message,an idea,a picture,or speech that is received and understood clearly and correctly by the person for whom it is sent.
Answer:
Communication.
Explanation:
Communication can be defined as a process which typically involves the transfer of information from one person (sender) to another (recipient), through the use of semiotics, symbols and signs that are mutually understood by both parties.
In this context, communication is the way to convey a message, an idea, a picture, or speech that is received and understood clearly and correctly by the person for whom it is sent.
Generally, the linear model of communication comprises of four (4) main components and these are;
1. Sender (S): this is typically the source of information (message) or the originator of a message that is being sent to a receiver. Thus, they are simply the producer of a message.
2. Channel (C): this is the medium used by the sender for the dissemination or transmission of the message to the recipient. For example, telephone, television, radio, newspapers, billboards etc.
3. Message (M): this is the information or data that is being sent to a recipient by a sender. It could be in the form of a video, audio, text message etc.
4. Receiver (R): this is typically the destination of information (message) or the recipient of a message that is being sent from a sender.
