Question 1

Files and folders deleted from removable media cannot be restored by any method.

Accepted Answer

It is possible to recover deleted files and folders from removable media using data recovery software. However, the chances of successful recovery depend on various factors such as the extent of data overwrite and the type of storage media.

Question 2

Linux is increasingly being used with both mainframes and supercomputers.

Accepted Answer

Linux has gained popularity in the high-performance computing industry due to its open-source nature, flexibility, and scalability. It is commonly used in mainframes and supercomputers as well as in clusters and cloud computing environments.

Question 3

Large computer systems-such as high-end servers, mainframes, and supercomputers- sometimes use operating systems designed solely for that type of system.

Accepted Answer

Large computer systems often require specialized operating systems designed to handle the specific hardware and workload requirements of those systems. These operating systems may not be practical or necessary for smaller or more general-purpose computer systems.

Question 4

File compression programs reduce the size of files so they take up less storage space on a storage medium or can be transmitted faster over the Internet.

Accepted Answer

File compression programs use algorithms to compress files which reduces their size, thereby requiring less storage space or decreasing the time required for transmission over the Internet.

Question 5

Although Linux originally used a command line interface, most recent versions of Linux programs use a graphical user interface.

Accepted Answer

Most recent versions of Linux programs use a graphical user interface, though the command line interface is still widely used and accessible.

Question 6

File extensions should not be changed by the user because the operating system uses them to identify the program that should be used to open the file.

Accepted Answer

Changing file extensions can cause the operating system to misidentify the program needed to open the file, leading to errors or potentially even security risks. It's best to leave the extension as it is, or consult with an expert before changing it.

Question 7

Using virtual memory is faster than just using RAM.

Accepted Answer

Virtual memory allows the computer to use the hard drive as if it were extra RAM, but accessing data from the hard drive is much slower than accessing data from actual RAM. Therefore, using only RAM is faster than using virtual memory.

Question 8

Once a file management program is open, you can look at the folders and files stored on your PC.

Accepted Answer

When a file management program, such as Windows Explorer or macOS Finder, is open, you can usually see the folders and files stored on your computer.

Question 9

Windows 98 was built from the ground up using a different kernel than the other versions of Windows.

Accepted Answer

Windows 98 was based on the same kernel as Windows 95.

Question 10

In practice, the difference between system and application software is not always clear cut.

Accepted Answer

While system software is designed to manage and operate the computer hardware and provide a platform for running applications, application software is designed to perform specific tasks or functions for the user. However, some software programs can have elements of both, making the distinction between system and application software less clear. Additionally, some software programs may be classified differently depending on their context or purpose.

Question 11

When you issue the command for your computer to store a document on your hard drive, the application software must make sure that such a drive exists.

Accepted Answer

The application software does not need to check if the hard drive exists; it is the computer's operating system that manages the storage devices and handles the actual saving of files.

Question 12

Filename rules are the same in all operating systems.

Accepted Answer

Filename rules can vary between operating systems. For example, some operating systems allow spaces in filenames while others do not.

Question 13

As you work on your computer, the operating system is in charge of managing system resources and making them available to devices and programs when they are needed.

Accepted Answer

The operating system is responsible for managing system resources such as memory, CPU, and input/output devices, and allocating them to programs and applications as needed.

Question 14

There is still a large installed base of Windows XP users and Microsoft plans to support Windows XP until 2014.

Accepted Answer

Microsoft announced in 2014 that they would discontinue support for Windows XP, however, they continued to provide critical security updates for XP until April 8th, 2014. Therefore, there was an installed base of Windows XP users up until that point and Microsoft did support XP until that date.

Question 15

Most operating systems today use a text-based user interface.

Accepted Answer

Most operating systems today use a graphical user interface (GUI) that allows users to interact with the system using icons, windows, menus, and other graphical elements. However, some operating systems, such as Linux, still use a text-based user interface as an optional alternative.

Question 16

There are two primary forms of DOS: PC-DOS and MS-DOS.

Accepted Answer

PC-DOS and MS-DOS are two primary forms of DOS.

Question 17

Stand-alone utility programs are often available in a suite of related programs.

Accepted Answer

Stand-alone utility programs may be available as a part of a suite of related programs, but they can also be offered individually.

Question 18

There are many stand-alone utility programs available as an alternative to the operating system's utility programs.

Accepted Answer

This statement is true. There are many stand-alone utility programs available that can perform similar or enhanced functionality compared to the utility programs that are bundled with an operating system.

Question 19

You press Ctrl+Alt+Insert to bring up the screen shown in the accompanying figure.

Accepted Answer

The answer of  You press Ctrl+Alt+Insert to bring up...

Question 20

Using the Save As option of the File menu before editing a document is a good idea, so you can return to the original version, if needed.

Accepted Answer

Saving the original version of a document before making changes is a good practice so that you can go back to the original if needed. The Save As option creates a new copy of the document while leaving the original intact.
