chapter 1 OS

Which of the following is NOT a task performed by the computer's BIOS?

manages random access memory

Which of the following is a job typically performed by the kernel?

managing CPU interactions

Describe the function of a device driver.

A device driver is a software that gives the hardware input the ability to communicate with the os or software.

Describe the role of a resource manager.

A software that manages the hardware and software of the system

Which of the following can be described as program code that operates like a specialized hook into the operating system?

API application program interface (allows apps to communicate with one another )

If you need to change specific parameters controlling the way your computer boots, which of the following components would you configure?

BIOS

Which of the following is low-level programming code capable of starting a full-fledged operating system?

BIOS

You want to design a small portable computer system with memory that can be updated, but that does not lose its contents when the device is turned off. What chip should be used?

CMOS

What essential part of the operating system communicates with the BIOS, device drivers, resource managers, and APIs to coordinate operating system functions?

Kernel

Which operating system, usually distributed for free, relies on open source software that is developed by volunteers and contains code in the public domain?

Linux

Which of the following accurately describes preemptive multitasking?

The OS allocates resources to applications but remains in full control

Which of the following was the first widely used multiuser, multitasking OS?

Unix

A word processor is best described as which type of operating system element?

application software

You have installed a new network adapter in a computer and rebooted the operating system. You go to check the settings of the network adapter, but you cannot find the device present in Windows. What is the most likely problem?

bad or missing device driver

Which particular type of low-level code is responsible for starting an operating system on a computer?

basic input/output system

When a computing environment requires that some processing of applications takes place on a server and on a PC-class computer, which type of system are you using?

client/server system

Which of the following can be described as a client/server computing model that offers scalable Web-based applications and services over the Internet?

cloud computing

The code that exchanges information with specific hardware devices is referred to as which of the following?

device driver

The core of an operating system that coordinates system functions is referred to as the CPU.

false

Which type of computer is most likely to be used for graphical design, film design, and animation?

high-end workstation

You are currently designing a cloud computing system that will host scalable Web-based applications accessible through a Web browser. This system will be available only to your company, but the resources will be made available through a third-party. What type of system should you use?

hosted private cloud

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 necessary. Which component is likely to be the cause of this problem?

kernel

Which type of operating system would be best when implementing a new computing system for an industrial plant that will require an accurate system to receive and process inputs, and calculate the expected outputs in a specified period?

real-time

What type of programs specifically manage central processor and computer memory?

resource managers

Describe the role of the BIOS on a computer.

the BIOS is the low level code that communicates with the basic hardware of the computer.

Describe the difference between a time-sharing system and a real-time system.

time-sharing is more focused on multiple users and multitasking while real-time is focused on one thing at a time with a time constraint on its abilities.
