Question 3

A user, Tim, is sitting at a Windows 10 client computer running an application when he sees a message that another user is trying to access the computer remotely using RDP. The other user cannot access the computer until Tim signs out of Windows. What type of OS is the computer most likely running?
A) single-user
B) single-tasking
C) multiuser
D) server

Accepted Answer

Windows 10, in its standard configurations (such as Home and Professional editions), is designed as a single-user operating system. This means that while it can run multiple applications simultaneously (multi-tasking), it is primarily intended for use by one user at a time. The scenario described, where another user cannot access the computer via Remote Desktop Protocol (RDP) until the current user signs out, is characteristic of a single-user OS environment. In contrast, server or multiuser operating systems are designed to allow multiple users to access and use the system concurrently.

Question 4

A user typed the name of a program at the command-line and pressed Enter. A user interface appeared on the screen. What function did the OS perform?
A) started a process
B) loaded a driver
C) scheduled a service
D) loaded the file system

Accepted Answer

When a user types the name of a program at the command-line and presses Enter, the operating system starts a process for that program. This involves allocating memory and resources for the program to run, and then executing it.

Question 5

Which of the following is created by a device to get the CPU's attention when a device has input or output data that is ready to process?
A) file handle
B) polling
C) interrupt
D) trap

Accepted Answer

An interrupt is a signal sent to the CPU by a device to indicate that it needs the CPU's attention, typically because it has input or output data ready to be processed. This mechanism allows the CPU to respond to events as they occur, rather than constantly checking (polling) the status of each device.

Question 6

Which of the following is a service most likely provided by a server OS?
A) web browser
B) word processor
C) DHCP client
D) directory service

Accepted Answer

A directory service is a network service that stores, organizes, and provides access to information in a directory, which is a common service provided by server operating systems.

Question 9

Which of the following accurately describes preemptive multitasking?
A) The OS waits for an application to release control of the processor.
B) The OS is in strict control of which processes get CPU time.
C) The user controls which application uses the CPU and when.
D) The CPU lets each application run for a fixed amount of time.

Accepted Answer

Preemptive multitasking is a method where the operating system decides which processes get CPU time and can interrupt them to allocate time to others, ensuring efficient CPU usage.

Question 10

Which type of computing device is designed to perform a specific task such as controlling a refrigerator, and has less than 64 KB of RAM?
A) supercomputer
B) embedded system
C) real-time OS
D) mainframe

Accepted Answer

Question 11

Which of the following is NOT a task performed by the computer's BIOS?
A) performs diagnostic tests
B) manages random access memory
C) starts the bootloader
D) initializes I/O devices

Accepted Answer

The BIOS (Basic Input/Output System) is responsible for performing diagnostic tests, starting the bootloader, and initializing I/O devices when the computer is turned on. However, managing random access memory (RAM) is not a task performed by the BIOS; this is handled by the operating system once the system has booted up.

Question 12

You are testing out a new multitasking operating system. In your testing, you find that some applications are not getting sufficient CPU time while other applications are getting more than enough CPU time. Which component is responsible for determining how much CPU time each application gets?
A) BIOS
B) CPU
C) shell
D) kernel

Accepted Answer

The kernel is responsible for managing system resources, including CPU time allocation among applications, ensuring that each application gets the necessary CPU time to function properly.

Question 13

If you need to change specific parameters controlling the way your computer boots, which of the following components would you configure?
A) CPU
B) API
C) BIOS
D) Kernel

Accepted Answer

The BIOS (Basic Input/Output System) is responsible for booting up a computer and initializing hardware during the startup process, making it the component you would configure to change specific parameters controlling the way your computer boots.

Question 14

You want to terminate a process on a Linux computer using the kill PID command where PID is the process ID and you don't know the process ID. Which command do you need to run first?
A) ls
B) ps
C) rm
