In general, data is any set of characters that has been gathered and translated for some purpose, usually analysis. It can be any character, including text and numbers, pictures, sound, or video. If data is not put into context, it doesn't do anything to a human or computer.

Within a computer's storage, data is a collection of numbers represented as bytes that are in turn composed of bits (binary digits) that can have the value one or zero. Data is processed by the CPU, which uses logical operations to produce new data (output) from source data (input).

What are the benefits of writing functions that use parameters and return List 2 please and explain what is return
Ratling [72]

<u>Answer and explanation:</u>

There are many benefits of writing functions that use parameters and return. Some of them are:

1. Flexibility: With functions having parameters, several values of the parameters can be used at invocation time thereby making the application flexible. For example, given the following function in Java.

<em>public void showName(String name){</em>

<em>    System.out.println("Your name is " + name);</em>

<em>}</em>

To call this method (function), the programmer could use various values for the name parameter used in the function like so:

showName("John");

showName("Doe");

If the function didn't have a parameter, it is possible it will only print a hardcoded name every time the function is called.

2. Scope Control: When a function is allowed to return a value, it helps to work around scope issues since variables declared within a function are limited to that function and do not exist outside the function. This means that the values of these variables cannot be used anywhere else outside the function in which they are being declared. However, if the function returns a value, the value can be used anywhere else in the program.

For example:

<em>public String getDouble(int x){</em>

<em>    int y = x * 2</em>

<em>    return y;</em>

<em>}</em>

The function above returns twice the value of the argument supplied to it. Since the integer variable y is declared within the function, it's value cannot be used outside the function. However, since the value is being returned by the function, it could be used anywhere the function is being called. Thanks to the return keyword.

Cloud [144]

Arturo is attempting to protect the database (data) of an information system (IS).

<h3>What is an information system?</h3>

An information system (IS) can be defined as a set of computer systems, that is typically used to collect, store, and process data, as well as the dissemination of information, knowledge, and the distribution of digital products.

In Cybersecurity, there are two (2) main techniques that can be used to check data when inputted in an information system (IS) and these include:

  • Verification
  • Validation

Data validation is a type of check which is primarily performed by a software program (application) to make sure that the data which is entered into an information system (IS) is allowable and sensible.

This ultimately implies that, any data that is not allowed or sensible are rejected and discarded by the computer system.

In conclusion, we can deduce that Arturo is attempting to protect the database (data) of an information system (IS).
