Answer:
Option (d)
Explanation:
Option (a) the return type of the method specifies the type of the data that is returned for the method calling. The return type can be void if it doesn't return any value. The method return can be int, string and bool etc. So, option (a) is true and it not the correct option.
Option (b) is true it doesn't need any parameters. So, option (b) is not the correct option.
Option (c) is true. If the method has some return type other than void it must return something according to the return type.So, option (c) is not the correct option.
Option (d) is false. Getters and setters methods are used for accessing private variables but the name MUST start with get or set is false. The best practice is to start with get and set but it is NOT a must.
So, option (d) is correct option.
Answer:
Single User OS.
Explanation:
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.
There are different types of operating systems (OS) used for specific purposes and these are;
1. Batch Operating System.
2. Multitasking/Time Sharing OS.
3. Multiprocessing OS.
4. Network OS.
5. Mobile OS.
6. Real Time OS .
7. Distributed OS.
8. Single User OS.
A Single User OS is a type of operating system that only allows one user to perform a task or use a system at any time.
In this scenario, you are working with an online tech service to fix a problem with installation of a program on your machine. You grant them remote access to your computer to enable them to act as you to fix situation. Therefore, the type of OS which must be installed on your machine to allow this type of action by another person is called a Single User OS.

Group of answer choices.
A. Spreadsheet program
B. Microsoft Windows Explorer
C. Word-processing program
D. Notepad
Answer:
B. Microsoft Windows Explorer
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.
In this scenario, you saved a file on drive "C" of your computer. The software program or application which you would use to find and open the file is Microsoft Windows Explorer.
The Microsoft Windows Explorer is an inbuilt resources that avails the end users the ability to perform various operations on a file and it provides the folder paths used for the storage of user files. It is the default program for file and folder documents on a computer system.
Using the knowledge in computational language in LC-3 Assembly it is possible to write a code that replaces the value in R0 with its absolute value
<h3>Writting the code </h3>
.ORIG x0200
START
AND R0, R0, #0 ; copy R0 to itself to set the condition codes based on R0;
; i.e performing addition operation with Zero option to set the flags
BRzp DONE ; if R0 is NON-NEGATIVE, skip the negation (already correct);
; Branch to DONE if number is poistive
NOT R0, R0 ; R0 is negative, so negate it i.e taking 2's complement
ADD R0, R0, #1 ; R0 = -R0 is performed successfully
DONE BR START
.END
