IT Essentials Chapter 5 Quiz Answers Online

Network operating systems, sometimes called server operating systems, are designed to support many users who connect to a server over a network. Many network users can access storage and printer resources and can run multiuser applications at the same time. Desktop operating systems can support a limited number of users who access shared resources. However, security and user management functionality is limited. So while desktop operating systems have limited network sharing capabilities, most businesses will require the use of a network operating system for serious business use.

Pressing the F8 key during the boot process will allow the user to choose to start the computer in Safe mode.

Hard disk drives are organized by several physical and logical structures. Partitions are logical portions of the disk that can be formatted to store data. Partitions consist of tracks, sectors, and clusters. Tracks are concentric rings on the disk surface. Tracks are divided into sectors and multiple sectors are combined logically to form clusters

Multiprocessing allows an operating system to use two or more CPUs. Support for two or more users is provided by the multiuser feature. Multitasking allows multiple applications to run at the same time. Multithreading allows different parts of the same program to run at the same time.

The tracks of a hard drive form complete circles on the disk platter surfaces. The tracks are divided into multiple sectors, and the sectors are grouped into clusters.

The Windows Compatibility Center allows a technician to check compatibility of software and hardware with Windows operating systems through an online utility. The Windows Upgrade Advisor is used to run a scan on a system to detect incompatible software and hardware. Windows Easy Transfer allows a technician to migrate personal files and settings from one computer to another. The Microsoft System Preparation tool is used to prepare an operating system created on a base system to be copied onto multiple computers.

NFS (Network File System) is used to access files on other computers across a network. Windows operating systems support several file systems. FAT, NTFS, and CDFS are used to access files stored on drives installed in the computer.

The Microsoft Windows Compatibility Center is an online resource that allows a computer technician to verify that specific hardware and software are proven to work with a particular version of Windows.

Thread is a small piece of a program in execution. Multi-processing is related to a system with more than one processor. Multi-user is related to a system that supports more than one user at the same time. Multi-task is a system that can perform more than one task at the same time.

The registry contains information about applications, users, hardware, network settings, and file types. The registry also contains a unique section for every user, which contains the settings configured by that particular user.

Master boot record (MBR) is the boot sector standard that supports a maximum primary partition of 2TB. MBR allows four primary partitions per drive. The globally unique identifier (GUID) partition table standard (GPT) can support enormous partitions with a theoretical maximum of 9.4ZB (9.4 x 10 to the 24th bytes). GPT supports a maximum of 128 primary partitions per drive.

When cloning an operating system to be installed on multiple computers, a technician can use Sysprep to remove undesirable settings that should not included in the cloned image.

Two types of computer operating system user interfaces are CLI and GUI. CLI stands for command-line interface. In a command-line interface, a user enters commands at a prompt using a keyboard. The second type is the GUI, or graphical user interface. With this type of user interface, a user interacts with the operating system by working with icons and menus. A mouse, finger, or stylus can be used to interact with a GUI. PnP is the name of a process by which an OS assigns resources to different hardware components of a computer. The other answers are examples of Application Programming Interfaces, or APIs.

A RAID 5 volume creates partitions on multiple redundant hard disk drives. Data is stored in stripes across those disks and a parity check is provided for each stripe. RAID 5 volumes are fault tolerant.
