Which of these is NOT considered an aspect of a Type 1 hypervisor?

A Type 1 hypervisor runs as a software application "within" a host's operating system. A Type 1 hypervisor doesn't run as a software application "within" a host's operating system; that is an aspect of a Type 2 hypervisor.

Which of the following is NOT an example of a workstation operating system?

A mobile device operating system like Apple iOS. A mobile device OS is one designed for handheld devices, such as smartphones and tablets. Mobile devices by definition are not workstations, so a mobile device OS is the only OS that is not for use on workstations.

What type of device uses the iOS operating system?

An Apple mobile device.

Which statement about an embedded operating system is true?

An embedded system is a computer system or appliance designed for a very specific function. Embedded systems are specifically used to operate devices that perform acutely time-sensitive tasks. Examples include drip meters and flow valves.

What is a hotfix?

An update that is typically issued on an emergency basis to address a specific security vulnerability. A hotfix is an update that is usually issued as an immediate response to a specific flaw or vulnerability.

Which of the following is an open source mobile operating system?

Android. The only open source mobile operating system in this list is Android. It was developed by Google based on a modified version of the Linux kernel and other open source software and was designed primarily for touchscreen mobile devices.

In the Windows operating system, where do you navigate to when you want to install new operating system features?

Control Panel. Windows users navigate to the Control Panel to install new operating system features. Within Control Panel, you navigate to Programs and Features and then to Turn Windows Features on or off.

How can you implement access control/protection on your computer?

Create ordinary user accounts for day-to-day access to the computer. When the OS is first installed, the account created or used during setup is a powerful local administrator account. You should create ordinary user accounts for day-to-day access to the computer.

You need to partition a disk into two separate drives. Where would you go to do this?

Disk Management. Windows provides a GUI Disk Management tool to format mass storage devices (disks and USB drives) and manage partitions. Also, each partition must be formatted with a file system so that the OS can read and write files to the drive.

What is the purpose of firmware in an embedded system?

Firmware provides all the functions for interacting with the device hardware. The embedded OS in an embedded system is called firmware because it is not designed to be continually changed and it provides all the functions for interacting with the device hardware. Workstations, laptops, and servers also use a type of firmware. Such PC firmware provides a low-level interface that allows the OS to load and take control of the PC's components.

After installing an application, you experience difficulty getting it to run. What should you do?

Inspect the properties of the executable file. You should inspect the properties of the executable file (or a shortcut to it). The Details tab is useful for troubleshooting, as it will let you know whether you are running a version with the latest patches. The Compatibility tab can be used to run the program in a compatibility mode (for Windows 98, for instance) and adjust the display settings.

What needs to be installed on a PC to manage computer hardware and software resources?

Operating system.

In which situation would Windows Disk Defragmenter be helpful?

Performance is being affected by used and free storage areas on a hard disk being greatly scattered. Windows Disk Defragmenter is helpful when performance is being affected by used and free storage areas on a hard disk being greatly scattered. Over time, a disk can become fragmented. Files that are saved on a disk are stored in multiple separate blocks, which causes the used and available storage areas to become scattered on the disk. A high degree of file fragmentation can impact the performance of the disk. Disk Defragmenter fixes this problem by rearranging the stored files to be contiguous rather than dispersed.

What is the basic function of an operating system?

Providing an interface between user and machine. The most basic function of an operating system is to provide an interface between user and machine.

Which option is NOT among the basic functions of an operating system?

Providing productivity applications such as word processing and spreadsheets. Providing productivity applications, such as word processing and spreadsheets, is not among the basic functions of an operating system. These must be acquired and installed separately. The applications are often written for specific operating systems. For instance, Microsoft Office was coded with a Windows operating system in mind, and might not function on a Macintosh operating system.

If you are interested in viewing real-time statistics of processor and memory usage, which Windows operating system tool should you open?

Task Manager.

In the Device Manager window, you notice a yellow exclamation mark next to a specific device. What is most likely the problem?

The driver for that device is either missing or the wrong version. When a yellow alert is displayed next to a device in the Device Manager window, it indicates a problem with that particular device. In most cases, there is a problem with the driver. Installing the most current driver for the device is a recommended first step.

What manages memory on a computer?

The operating system will do the best job it can with the resources available. There is not a lot to configure in terms of memory management. The OS will do the best job it can with the resources available; if there is not enough memory the only real solution is to install more or run fewer programs simultaneously.

Why are server operating systems likely to include software packages (or roles)?

They often use one role to run network services and a different role to support specific functions for more users. Servers can be configured to perform a number of roles. The applications that the server is running specify the particular server's role. Servers typically need services and additional features installed to perform their specific role. The server's role determines the hardware that server requires. A few common server roles are domain controller, database server, backup server, file server, print server, infrastructure server, web server, and email server.

If you can't end a task by closing it or ending it normally, what is the best way to "kill" the process?

Use the Task Manager utility to end the task
