Answer:

System softwares.

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.

Basically, softwares are categorized into two (2) main categories and these are;

I. Utility software.

II. System software.

The operating systems, and utility programs that perform system maintenance and protection tasks such as error correction and backup are called system softwares.

An operating system is a system software pre-installed on a computing device to manage or control software application, computer hardware and user processes.

This ultimately implies that, an operating system acts as an interface or intermediary between the computer end user and the hardware portion of the computer system (computer hardware) in the processing and execution of instructions.

Some examples of an operating system on computers are QNX, Linux, OpenVMS, MacOS, Microsoft windows, IBM, Solaris, VM etc.

On the other hand, a utility software can be defined as a software application or program designed to add more functionality to a computer system, as well as to improve its performance efficiently. Some examples of commonly used utility tools in computer are file and folder backup tools, file management, antivirus, hard disk diagnostics, registry cleaner, network performance monitor, screensavers etc.

Using your favorite imperative language, give an example of each of the following. (a) A lexical error, detected by the scanner

Travka [436]

Explanation:

a. int foo+; (foo+ is an invalid identifier because + is not a valid char in identifiers)

b. foo int; (Syntax error is any error where the syntax is invalid - either due to misplacement of words, bad spelling, missing semicolons etc.)

c. Static semantic error are logical errors. for e.g passing float as index of an array - arr[1.5] should be a SSE.

d. I think exceptions like NullReferenceException might be an example of DME. Not completely sure but in covariant returns that raise an exception at compile time (in some languages) might also come in this category. Also, passing the wrong type of object in another object (like passing a Cat in a Person object at runtime might qualify for DME.) Simplest example would be trying to access an index that is out of bounds of the array.

The area of a square is stored in a double variable named area. Write an expression whose value is length of the diagonal of the

melisa1 [442]

Answer:

sqrt(area)

Explanation:

Here sqrt is a short form of square root.
area is a variable name having he area of square.
When the function is called, it will give the square root of the value stored in variable area.

As we have to find the length of the diagonal, we must knew that as all sides of the square are same in length so are the diagonals. This means that each of the four sides of the square and it diagonals are equal in length.

So a square has: length=breadth=diagonal

As Area= length*breadth

√area = length (as length = diagonal length)

So √area = diagonal length

The most significant difference between improving an existing process and designing a new process is that as a person is completely working again on a process or designing a new process, there are known to be a lot of unknowns factors that may occur.

<h3>What is the difference about?</h3>

In working or redoing a process or designing any kind of new process, there are known to be a lot of unknowns factors.

This is said to be the most significant difference that exist between improving a process and designing a new process. This makes a lot of new processes and products to be very focus on meeting their customer's performance needs or aims.
