- 1Two Common build software products come in(32 bit) builds (a.k.a. IA-32)
Typically associated with: older, abandoned, unmaintained, or outdated
software products
(64 bit) builds (a.k.a. x86_64)
Typically associated with: newer, actively maintained, updated,
mainstream software products - 2Microsoft Window Releasing HistoryDesktop Class (RTM Date ; Available Builds)
- Microsoft Windows 8.1 (Aug 2013 ; 32/64 bit)
- Microsoft Windows 10 (Jul 2015 ; 32/64 bit)
Server Class (RTM Date ; Available Builds)
- Microsoft Windows Server 2012 R2 (Oct 2013 ; 64 bit)
- Microsoft Windows Server 2016 (Sep 2016 ; 64 bit)
- Microsoft Windows Server 2019 (Oct 2018 ; 64 bit) - 3Microsoft window build versionsMicrosoft Corporation additionally uses a (4-digit) code to indicate a major update (Build Version) to their operating system software products. A higher value is deemed to be “newer”, as the first (2-digits) indicate the “year”, and the last (2-digits) indicate the “month” of the major update release
When downloading or upgrading Microsoft-based operating systems, you will likely be comparing your existing build version, to ones that are newly available
Examples:
Microsoft Windows 10 (1903) … March 2019 Update
Microsoft Windows Server 2019 (1809) … September 2018 Update
Microsoft Windows 10 (1803) … March 2018 Update - 4Apple macOS release historyProduct Version (RTM Date ; Available Builds)

When the physical computer system is initially booted (or restarted), any changes to the host are removed, and cannot be recovered
Warning !!!
If you have data located on a storage device which is not your portable USB-powered storage device, or a personal USB thumb drive ... it will be lost forever ... if the host computer system is powered down or has to be restarted
Ensure your important data files are located on your own personal storage device - 10Virtual MachinesVirtual Machining is a very popular technology used today, both in the workplace and for personal use
The biggest benefit to working with virtual machines is the ability to run multiple host operating systems on a single physical computer system simultaneously
The native operating system installed directly on the physical computer system, is referred to as the Host OS
All other operating systems, running within separate virtual machines, are each referred to as a Guest OS
Each Guest OS has access to the Host OS’ hardware resources (processor, memory, network adapter, etc.). The Host OS’ hardware resources are presented to each Guest OS as virtualized hardware components
For students in the networking programs, there are (2) courses available which are dedicated to just virtualization - 11Virtualization UsagesCommon usages of virtualization in your college program include:
- Creating small networked environments
- Creating software development environments
- Learning to work with software products where separate dedicated
computer systems are not available
- Testing out new software products or software product updates
- Installing and testing your custom written applications (computer
programs) on a non-development computer system
- Creating back-end environments used in the testing of mobile applications - 12Virtualized HardwareHardware which you want to make available to a Guest OS is defined in a virtual machine configuration profile
Typical hardware that is virtualized and presented to a Guest OS include:
- CPUs (one or more processors)
- Memory
- Graphics Adapter
- Sound Card
- Keyboard
- Mouse
- Storage Devices (virtual hard disks)
- To store the Guest OS’ operating system, applications, and data
- Optical Storage Devices (virtual CD/DVD-ROM drives)
- Used to install the operating system, and other software products, from
an installation media source (e.g. CD/DVD ISO file)
- Network Adapters
- Used to communicate with the Host OS, other Guest OSes, and the
Internet - 13Virtual Network AdaptersBridged
- Configured with an IPv4/IPv6 address, just like a real physical network
adapter
- Can communicate on the network, just like any other physical network
device
- Can communicate out to the Internet
NAT (Network Address Translation)
- Configured with a special reserved IPv4/IPv6 address
- Can communicate with other devices beyond the Host OS, including the
Internet
- By default, cannot be communicated with by other Guest OSes running
on the same physical host
- By default, cannot be communicated with by other hosts anywhere on the
network - 14Virtual Network Adapters 2Internal Network
- Used to create small isolated network environments
- Requires an arbitrary logical network name (e.g. intnet), common to all
Guest OSes communicating in the same small network
- Cannot communicate with the Host OS
- Cannot communicate with (or be communicated by) other hosts anywhere
on the network
- Cannot communicate with other Guest OSes which are not configured to
use the same logical network name (e.g. intnet)
- Cannot communicate out to the Internet
Host-only
- Can communicate with the Host OS
- Can communicate with other Guest OSes configure with the same
network adapter type (Host-only)
- Cannot communicate beyond the Host OS, including the Internet - 15Popular Virtualization PlatformsMicrosoft Hyper-V

virtualization - 16Popular Virtualization Platforms 2VMware ESXi
- Must be purchased ($$$)
- A dedicated bare-metal installation
- Used for network infrastructure virtualization, and not for personal use
virtualization
- Most popular virtualization platform in the workplace
VMware Workstation Pro
- Must be purchased ($$$)
- Installed as an application on the host computer system
- Used for personal use virtualization, and not for network infrastructure
virtualization
- Available for only (2) of the major host operating system platforms
- Microsoft Windows, Linux variants - 17Popular Virtualization Platforms 3Oracle VM
- Free to use ... however ... most installations in the workplace are
protected by an annual maintenance agreement which costs money
- A dedicated bare-metal installation
- Used for network infrastructure virtualization, and not for personal use
virtualization
- Most popular virtualization platform in the workplace for Oracle Database
installations
Oracle VM VirtualBox
- Free to use (for personal and educational purposes)
- Installed as an application on the host computer system
- Available for all (3) major host operating system platforms
- Microsoft Windows, Apple macOS, and Linux variants
- Used for personal use virtualization, and not for network infrastructure
virtualization - 18Course Specifics- Use the Oracle VM VirtualBox virtualization platform to create virtual
machines and work with Guest OSes
- Use the (NAT) virtualized network adapter only when communications out
to the Internet is required. This network adapter will primarily be used for
the initial installation of each of the (3) Guest OSes at the beginning of the
course
- Use the (Internal Network) virtualized network adapter when
communications out to the Internet is not required. This network adapter
will be used for most modules (3 through 12) and for all Guest OSes
