Chapter 6 Operating Systems Flashcards
A key purpose of operating systems is to:
keep track of all the files that are used on a computer
A file system describes:
how data and drives are organized
In Windows the file system you choose for a hard drive affects the following:
The rules for how large a logical drive (Drive letter) can be and whether the hard drive can be used as one big drive letter or several smaller drive letters or whether it must be multiple drive letters
The efficiency of data storage (the less waste space, the better)
The security of a system against tampering
Whether a drive can be accessed by more than one operating system
FAT32 was introduced in:
1995
FAT32 has the following characteristics:
It has a 32-bit file allocation table, which allows for 268,435,456 entries per drive. An entry can be a folder or an allocation unit used by a file
The root directory can be located anywhere on the drive and can have an unlimited number of entries, which is a big improvement over FAT
FAT32 uses an 8KB allocation unit size for drives as large as 16GB
The maximum logical partition size allowed is 2TB
The limitations of FAT32 are:
it can only support individual files up to 4GB in size
it can’t use file permissions
it doesn’t support journaling systems that can fix file corruption issues
FAT32 is still used:
to format flash memory cards and USB flash drives for use in not only workstation but media players
smart TVs
printers
cameras
anything else that has a USB port
exFAT is also known as:
FAT64 because it supports 64-bit addressing
exFAT is a:
file system designed to enable mobile personal storage media to be used seamlessly on mobile and desktop computers
exFAT is designed to be:
as simple as FAT32 but with many improvements in capacity and scalability
exFAT’s main features include:
It supports volumes larger than 32GB
The recommended and maximum file sizes increase to 512TB and 64ZB respectively
Improvements in file system structure enable better performance with flash media and for movie recording
It supports Universal Time Coordinate (UTC) date stamps
exFAT support is included in Windows 7,8/8.1, and 10
Operating systems can be classified as either:
open source
closed source
open source refers to:
software that is effectively free to download and modify
closed source refers to:
software that cannot be modified without express permission and licensing
Other terms used to describe closed source software are:
vendor specific
proprietary
vendor specific means:
only one company has access to the source code
proprietary means:
the software is owned and patented and can only be used with permission and usually by paying a licensing fee
Disk Operating Systems (DOS) is a:
command line OS, which means commands are entered as strings of text
Graphical User Interface (GUI) allows:
commands to be entered with the click of a mouse
macOS was released in:
2016
macOS was designed to:
integrate with devices using the iOS operating system, such as the iPhone, Apple TV, and Apple Watch
Linux was derived from:
the UNIX operating system
Linux is named after:
Linus Torvalds
Linux was developed in:
1991
What do companies like Red Hat do?
They modify Linux source code and then charge individuals and organizations to support the modifications
Linux is available as:
command line distros
or GUI distros
Smartphones are typically either:
Android
iOS
Windows Mobile
Some differences between Android and iOS smartphones include:
Operating system updates are provided by the wireless carrier for Android phones
Wireless carriers provide network-specific updates for iPhones (iOS), but Apple provides OS updates
Android’s OS is based on:
Linux kernel
Google also commissioned the:
Android Open Source Project (AOSP), whose mission is to maintain and further develop Android
iOS OS is based on:
macOS, and therefore has its roots in UNIX
Chrome OS is based on:
Linux and is installed on Chromebooks

BitLocker is a:
data encryption utility that encrypts hard drives for added security
BitLocker To Go encrypts:
removable disks and USB drives
Encrypting File System (EFS) has the capability of:
encrypting individual files
BranchCache is software designed to:
allow efficient use of bandwidth for remote clients and offices
BranchCache caches:
the most commonly requested data on a client computer so that bandwidth is not wasted on repetitive data requests
The boot process involves:
loading the necessary OS files into RAM so the computer becomes functional
The OS can be stored on:
the local hard drive
CD/DVD
an external USB or eSATA drive
another computer on the network
What is the BIOS/UEFI’s Boot Order settings used for?
To tell the computer where to go to find the OS files
When booting, the PC looks in the:
preferred place for files and loads them into RAM, and the computer then becomes operational
There are many methods to boot a system during the installation process:
Optical disc (CD-ROM/DVD/Blu-ray)
Network/PXE boot (Preboot Execution Environment
USB/eSATA boot (booting from USB thumb drive)
Internal hard drive (HDD/SSD)
Partition on the internal hard disk drive or SSD
The Microsoft Deployment Toolkit (MDT) is used for:
automated installation of Windows 7, 8.1, 10 and Windows Server 2008 R2 and newer versions
The Microsoft Deployment Toolkit (MDT) does what?
It creates and updates the Unattend.xml file (used to provide answers during the process) automatically during the deployment
How do you perform an in-place upgrade installation of Windows?
Start the installation process from within the existing version of Windows
In-place upgrades do not:
delete previous installations, which means the user can retain apps and settings as well as personal files
You can upgrade an OS only to:
the equivalent or better edition of Windows but not a lower edition
Before starting a clean install process check the following:
Make sure the drive for installation is placed before the hard drive in the boot sequence
If you will be installing to drive that might require additional drivers (SATA, RAID, or third-party host adapters on the motherboard or in an expansion slot), have the drivers available on any type of removable media supported by the system
If you are installing from optical media, from a disk image (ISO or VXD), or within a virtual machine (VM), after restarting the system with the CD or DVD media or image file in place, press a key when prompted to boot
During the installation process, be prepared to confirm, enter, select, or provide the following settings, information, media, or options when prompted:
Custom installation
Edition of Windows you are installing
Location (home, work/office, or public)
Network settings
Partition location, partition type, and file system
Password and password hint
Product key
Time, date, language, and region
Time zone, time, and date
Username and company name
Workgroup or domain name
A multiboot installation of Windows enables a choice between:
two or more operating systems when you start your computer
To use the multiboot support that is built in to Windows, follow these rules:
Install the oldest version of Windows first
Install Windows on a separate disk partition from the previous operating systems and prepare that partition as a primary partition
To install multiple editions of Windows for multibooting, ensure that each installation is on its own primary partition
The Windows multiboot support does not cover non-Windows OS such as Linux
If a Windows OS installation becomes corrupt, use a:
repair installation to restore working files and Registry entries without losing existing programs or information
To perform a repair installation of Windows 10 with a USB flash drive (which needs to be created before you start this process), follow these steps:
- Boot the computer normally and sign into the Administrator account
- Insert the flash drive and run setup.exe to start the setup
- When prompted, download and install updates
- Accept the end-user licensing agreement. The updates begin
- When the updates are ready, click Install when prompted
- Choose the keep personal files if that is the preference
- Let the Windows 10 Setup process run and repair Windows
The remainder of the installation proceeds as with a normal installation
A remote network installation (which involves installing Windows from a network drive) begins by:
starting the computer with a network client and logging on to the server to start the process
Why would you use Windows Deployment Services?
to automate the remote network installation process
An image deployment is the:
process of installing Windows from a disk image of another installation
The image deployment process is also known as:
disk cloning
If deploying a disk image to multiple computers, rather than as a backup of a single computer, consider these special issues:
Hardware differences
Same security identifier
To overcome disk image deployment issues use:
cloning programs designed to capture an image that can be deployed to different types of computers with different hardware and software
For Windows 10, use the System Preparation Tool (Sysprep) to:
prepare the image for installation over many computers
If you select Generalize in Sysprep, Windows:
removes unique PC information, including the SID. When the install completes and the computer is restarted, a new SID is generated
All cloning tools can work with:
a target drive that is the same size or larger than the original cloned system drive
Some cloning tools can work with:
a smaller drive
When is a recovery partition created?
When upgrading Windows or doing a clean install with Windows Setup
The recovery partition is:
a space that holds the Windows Recovery Environment (WinRE), which can repair some common boot errors
Windows Recovery Environment (WinRE) is built into:
Windows 10 versions of desktop editions
A hard drive cannot be used until it is prepared for use. There are two steps involved in preparing a hard drive:
- Create partitions
2. Format partitions (and assign drive letters)
A disk partition is a logical structure on a hard drive that specifies the following:
Whether the drive can be bootable
How many drive letters (one, two, or more) the hard drive will contain
Whether any of the hard drive’s capacity will be reserved for a future operating system or another use
Every hard drive must go through a:
partitioning process, even if you want to use the entire hard drive as a single drive letter
All versions of Windows support two or major types of disk partitions:
Primary partition
Extended partition
A primary partition can contain only:
a single drive letter and can be made active (bootable)
Only one primary partition can be:
active
Only one primary partition is needed on a drive that contains:
a single OS
If installing a new OS in a multiboot configuration with your current OS, install:
the new OS to a different disk partition than is used for the previous Windows version
If using a non-Windows OS along with your current OS, it should be:
installed into its own primary partition
A drive partitioned using GPT can have up to:
128 primary partitions
an extended partitions differs from a primary partition in two important ways:
An extended partition doesn’t get a drive letter but can contain one or more logical drives, each of which is assigned a drive letter
Neither an extended partition nor any drive it contains can be bootable
Only one extended partition can be:
stored on each physical drive
Extended partitions are used only with:
Master Boot Record (MBR) drives
Master Boot Record (MBR) partitions are supported by:
classic ROM BIOS
UEFI firmware
Master Boot Record (MBR) supports:
a maximum drive size of 2TB and up to four primary partitions
A GUID Partition Table (GPT) supports:
drives up to 256TB and up to 128 primary partitions
GUID Partition Table (GPT) is more reliable than Master Boot Record (MBR) because:
it protects the partition table with replication and cyclic redundancy check (CRC) of the partition table’s contents
GUID Partition Table (GPT) provides:
a standard way for system vendors to create additional partitions
GUID Partition Table (GPT) are supported by:
UEFI firmware
If a drive will be used by a single OS using a Master Boot Record (MBR) partition table, one of these three ways of partitioning the drive will be used:
Primary partition occupies 100% of the physical drive’s capacity
Primary partition occupies a portion of the physical drive’s capacity, and the remainder of the drive is occupied by an extended partition
Extended partition occupies 100% of the physical drive’s capacity
Primary partition occupying 100% of the physical drive’s capacity is suitable for:
the only drive in a system or an additional drive that can be used to boot a system but should not be used for additional drives in a system that will be used for data storage
Primary partition occupying a portion of the physical drive’s capacity, and the remainder of the drive is occupying an extended partition is a common setup for:
laptop but requires the partitioning process to be performed with different settings than the defaults
Extended partition occupying 100% of the physical drive’s capacity is suitable for:
additional hard drives in a system (not the first drive); an extended partition can contain only one logical drive or multiple logical drives
GPT partitioning creates:
one or more primary partitions
Windows Disk Management supports two types of disks:
basic
dynamic
A dynamic disk is:
more versatile than a basic disk because it can span two physical drives into a single logical drive, create striped or mirrored arrays, and adjust the size of a partition
Only basic disks can be:
bootable
When installing Windows 7/8/8.1/10 to an empty hard drive, there is a prompt for:
a location
To use all the space in the disk for creating partitions, make sure that:
the desired disk and partition is highlighted and click Next
To use only part of the space in the disk for creating partitions, follow these steps:
click Drive Options (Advanced)
click New
specify the partition size, and click Apply
A file system determines:
how data and drives are organized, but it is also general term for how an OS stores various types of files
The New Technology File System (NTFS) is the:
native file system of Windows 7/8/8.1/10
The New Technology File System (NTFS) has many differences from FAT32, including:
Access control
Built-in compression
Individual Recycle Bins
Support for Encrypting File System (EFS)
Support for mounting a drive
Disk quota support
Hot-swapping
Indexing
Follow these steps to determine what file system was used to prepare a Windows hard drive:
- Open Windows Explorer or File Explorer
2. Right-click the drive letter in the Explorer window and select Properties
During installation, Windows 7/8/8.1/10 automatically:
formats the partitions created by the partition process with NTFS

When should you use an Optical disc (CD-ROM/DVD/Blu-ray) to boot a system during the installation process?
to install Windows to one or more systems that have working network connections
When should you use a USB/eSATA boot (booting from USB thumb drive) to boot a system during the installation process?
when installing from a DVD isn’t feasible
Windows can be installed in a variety of ways. The most common methods are:
As an in-place upgrade to an existing version
As a clean install to an empty hard drive or to the same partition as the current version
As a multi-boot, which means installing to unused disk space (a new partition) to enable a choice between the current version and the new version, as needed)
As a repair installation to fix problems with the current installation
With the recovery partition (which resets the system to its original installed state)
Refresh and Reset in Windows 8/8.1
Large-scale or customized installations might use the following methods:
Unattended installation
Remote network installation
Image deployment
In an attended installation:
information must be provided at various points during the process
In an unattended installation:
you must create the appropriate type of answer file for the installation type
A swap partition is:
disk space partitioned to be available in case extra RAM is needed
A swap partition feature is called what in Windows?
virtual memory
A swap partition feature is called what in Linux?
swap space
A swap partition can not be used for:
storage
With new hard drives or existing drives that are known to be error free, you can use the quick format option to:
quickly clear the arears of the hard drive that store data location records
With the full format option, Windows must:
rewrite the disk structures across the entire disk surface.
If Windows does not detect hard drives during installation, an:
alternative third-party driver must be provided
The most likely situations in which Windows does not detect hard drives during installation are when:
third-party SATA or RAID onboard or add-on card host adapters are used in Windows 7/8/8.1/10
In Windows 7/8/8.1/10, device drivers are:
added using the same screen that is used for partitioning and clicking Load Driver
Device drivers can be installed from:
CD
DVD
USB flash drive
During the installation process, Windows can connect to either a:
workgroup (the default setting)
network managed by a domain controller
Domain controllers are typically used in:
large networks at workplaces or schools
What networks use workgroups?
Home networks
small-office networks
computers running Windows 7 or newer might also belong to one
For individual PCs, the easiest way to perform updates is to:
set up Windows Update for automatic updates
What is a factory recovery partition?
a disk partition containing a special recovery image of the Windows installation is provided
Typically, there are limited choices for restoring a damaged installation with a recovery disc or recovery files on a disk partition. Typical options include:
Reformatting the hard drive and restoring it to just-shipped condition (which causes the loss of all data and programs installed after the system was first used
Reinstalling Windows only
Reinstalling support files or additional software
