Question 1

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, although it is still possible to use a command line interface if preferred.

Question 2

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 3

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

Question 4

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

Accepted Answer

When you open a file management program, such as File Explorer on Windows or Finder on Mac, you are able to view the folders and files stored on your computer.

Question 5

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

Accepted Answer

This is true. PC-DOS was developed by IBM and MS-DOS was developed by Microsoft, but they are both forms of DOS.

Question 6

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 have specialized operating systems designed specifically for their unique hardware and processing needs.

Question 7

Filename rules are the same in all operating systems.

Accepted Answer

While there are some general guidelines for naming files that are consistent across operating systems (e.g. using letters, numbers, and underscores but avoiding special characters like / \ : * ? " < > |), there are specific rules and limitations that differ between operating systems. For example, Windows allows longer file names than MacOS, and Unix-based systems are case-sensitive while Windows is not.

Question 8

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 work by using various algorithms to compress the data in a file, resulting in a smaller file size. This can make it easier to store and transfer files, especially over the Internet where smaller files can be transmitted faster.

Question 9

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 check for the existence of the hard drive, it assumes that it exists and attempts to save the document to that location. It is the operating system's responsibility to handle errors related to non-existent drives or insufficient storage space.

Question 10

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

Accepted Answer

Most operating systems today use a graphical user interface (GUI) instead of a text-based user interface.

Question 11

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

Accepted Answer

Files and folders deleted from removable media can be restored using data recovery software if they have not been overwritten by new data.

Question 12

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

Accepted Answer

Stand-alone utility programs are often part of a suite of related programs, designed to work together to provide a comprehensive solution for a specific task or application. These suites may include word processing, spreadsheet, presentation, email, and other tools that are used together to create a complete office productivity environment.

Question 13

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

Accepted Answer

In reality, some software may have elements of both system and application software, making it difficult to categorize them solely as one or the other. Therefore, the difference is not always clear cut.

Question 14

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 the file extension can cause the operating system to not recognize the file type correctly and may not open it with the correct program.

Question 15

Linux is increasingly being used with both mainframes and supercomputers.

Accepted Answer

Linux has become popular for use in mainframes and supercomputers due to its flexibility, scalability, and open-source nature. Examples include IBM's z/OS mainframe operating system with Linux integration and the use of Linux in supercomputers such as IBM's Summit and Sierra.

Question 16

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

This statement is true. The operating system acts as a resource manager and ensures that applications and hardware devices have access to the system resources they require to function properly.

Question 17

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

Accepted Answer

Microsoft has announced that they will continue to provide security updates and support for Windows XP until April 8, 2014. However, after this date, they will no longer provide any support or updates for the operating system.

Question 18

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

This is true because the Save As option creates a new copy of the original document, allowing you to make edits without overwriting the original version. If you need to go back to the original, you can simply open it again, rather than having to recreate it from scratch.

Question 19

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

Accepted Answer

There are many stand-alone utility programs available for different purposes such as disk cleaning, system maintenance, file management, and many others, which users can install and use as an alternative to the operating system's built-in utility programs.

Question 20

Using virtual memory is faster than just using RAM.

Accepted Answer

Using virtual memory involves accessing data stored on the hard drive, which is much slower than accessing data stored in RAM. While virtual memory can extend the amount of available memory, it is not faster than exclusively using RAM.
