Question 1

Even if users are working on multiple programs simultaneously, it is impossible to run out of RAM.

Accepted Answer

It is possible to run out of RAM if users are working on multiple programs simultaneously and the RAM capacity is exceeded, leading to slow performance or crashes.

Question 2

In addition to managing applications, an operating system manages other processes.

Accepted Answer

An operating system manages various processes such as memory management, device management, file management, security, and error detection.

Question 3

To set up a virtual machine, you need software that can set up a virtual machine, as well as installation media for the operating system you wish to install in the virtual machine.

Accepted Answer

Setting up a virtual machine requires software such as VMWare, VirtualBox, or Hyper-V, and installation media for the desired operating system.

Question 4

NUIs are implemented in a variety of ways: touch screens, gesture recognition, speech recognition, and virtual reality.

Accepted Answer

Yes, NUIs can be implemented in all of these ways and more, including eye tracking and brain-computer interfaces.

Question 5

The method used to restart a computer or device differs, depending on the situation and the hardware.

Accepted Answer

Different devices may require different methods to restart, depending on their hardware and operating system.

Question 6

The start-up process is very different for large and small computers.

Accepted Answer

The answer of The start-up process is very different for...

Question 7

Because virtual memory is faster than RAM, users may notice the computer speeding up while it uses virtual memory.

Accepted Answer

This statement is false. Virtual memory is not faster than RAM. In fact, using virtual memory can actually slow down a computer because the process of transferring data between RAM and the hard drive (where virtual memory is located) takes time and can cause delays. RAM is typically faster because it allows for quicker access to data.

Question 8

Some parts of the operating system are resident; that is, these instructions remain on the hard disk until they are needed.

Accepted Answer

All parts of the operating system are loaded into memory when the computer starts up, so none remain on the hard disk until they are needed.

Question 9

When a computer is running multiple programs, the applications running but not currently in use are in the foreground.

Accepted Answer

The applications that are currently in use and visible on the screen are in the foreground. The applications running in the background are not visible but may still be running processes or tasks.

Question 10

Quickly pressing the power button on a laptop may place the computer in sleep mode.

Accepted Answer

When the power button is pressed quickly on a laptop, it may place the computer in sleep mode. However, this behavior can be customized in the power settings of the computer.

Question 11

The nexus is the core of an operating system that manages memory and devices.

Accepted Answer

The term "nexus" is not commonly used to refer to the core of an operating system. In some contexts, "nexus" may refer to a particular device or connection point within a system, but it is not directly related to memory management or device management.

Question 12

When a computer is running multiple programs concurrently, the one in the background is the active program; that is, the one currently in use.

Accepted Answer

The program in the foreground is the active program and the one currently in use. The program in the background is still running but is not currently in use or actively being interacted with.

Question 13

When turning on a computer that has been powered off completely, users are performing a warm boot.

Accepted Answer

Turning on a computer that has been powered off completely is known as a cold boot, not a warm boot. A warm boot is when a computer is restarted without being fully powered off.

Question 14

When you purchase a computer, it may include recovery media in the form of a CD.

Accepted Answer

Many computers come with recovery media in the form of a CD or DVD that can be used to restore the system to its factory settings if necessary.

Question 15

An operating system cannot run from an external drive.

Accepted Answer

An operating system can run from an external drive.

Question 16

Command-line interfaces like the one in the accompanying figure give a user less control to manage detailed settings.

Accepted Answer

The answer of  Command-line interfaces like the one in...

Question 17

As you interact with a program, part of it may be in physical RAM, while the rest of the program is on the hard disk as virtual memory.

Accepted Answer

This statement is true. When a program is running, parts of it may be loaded into physical RAM for faster access, while other parts are stored on the hard disk as virtual memory. This is a common technique used by operating systems to manage memory usage.

Question 18

With virtual memory, which is illustrated in the accompanying figure, when an operating system spends much of its time paging, instead of executing application software, it is said to be thrashing.

Accepted Answer

The answer of  With virtual memory, which is illustrated...

Question 19

A cold boot is generally faster than a warm boot.

Accepted Answer

The answer of A cold boot is generally faster than...

Question 20

Regardless of the size of the computer, most operating systems provide similar functions.

Accepted Answer

Most operating systems provide similar functions, regardless of the size of the computer they are installed on. This includes functions such as managing files and processes, providing a user interface, and connecting to networks. However, some specialized operating systems may offer unique functions based on the specific needs of the hardware or targeted users.
