Virtual Machines
• software emulation of a physical machine
• offers support to replicate a complete
machine with software
• run multiple OS-s on a single device
Virtual Machines
• The performance of a VM is limited by the
performance of the host computer
• The performance of the VM should always be
set lower than that of the host computer
• Recommended allocation is about ½ of
available resources
Virtual Machines
Virtual machine managers (VMMs) or
hypervisors:
• VirtualBox (free)
• Parallels ($79,99)
• VMware (Free/$189)
• Windows Virtual PC (free)
VirtualBox
Creating a new virtual machine:
• VM name and operating system
• Allocated RAM memory (in MB!)
• Virtual hard disk
– Virtual hard disk will take up as much space on
your physical drive as much as you configure
VirtualBox
15 mins.
Using VirtualBox create the following VM:
• Name: Windows10_yourname
• OS: Windows 10 (64-bit)
• RAM: 2 GB (2048 MB)
• Virtual hard disk (VDI)
– 40 GB, dynamically allocated
• Check settings after creation and correct core
allocation to ½ of total available
• Locate your virtual hard disk on your physical
machine. What is its actual size?
Hint: C:\Users\<user_name>\VirtualBox VMs

Operating systems
An operating system (OS) is a collection of
software that manages computer hardware
resources and provides common services for
computer programs.
Operating systems
Main functions:
• provide communication between the user
and hardware
• control program execution
• ensure optimal resource allocation
• facilitate efficient data processing
• ensure system security
• enable application development
Operating systems
Main components:
• core (kernel)
contains the necessary programs for optimal
resource management and for controlling the
activity of programs and applications
• user interface (shell)
software interface that provides the user access to
the services of the kernel
Operating systems
Most popular
• MacOS family
• Linux family
• MS-DOS
• Microsoft Windows family
• iOS family
• Android family
• …and many more

Operating systems
Disk partitioning
• the act of dividing a hard disk drive into
multiple logical storage units referred to as
partitions, to treat one physical disk drive as if
it were multiple disks, so that different file
systems can be used on each partition
Operating systems
File system
• file system (or filesystem) is used to control how
information is stored and retrieved
• without a file system, information placed in a
storage area would be one large body of
information with no way to tell where one piece
of information stops and the next begins
Operating systems
File systems for Windows:
• FAT
– File Allocation Table (multiple versions)
– max. file size: 4 GB
• NTFS
– New Technology File System (multiple versions)
– max. file size: 16 TB (Windows 7), 256 TB (Windows 8)
– usually faster that FAT32
Operating systems
Disk partitioning
• always create at least a system partition* and
a data partition
• always format the system partition when
reinstalling the OS
*
system partition should have at least 100 GB disk space for Windows 7 and newer
and should be formatted as NTFS
VirtualBox
45 mins.
On your Virtual Machine you created:
• Mount the Windows 10 ISO image found on your local
drive (D:)
• Start your VM and start the Windows 10 installation
process (advanced, not upgrade)
• Partition your disk 20GB + 20 GB (NTFS both)
• Start Windows 10 installation
• … later…
• Set the user name as your first name and complete the
install process
• On your physical machine search for the virtual hard
drive again. What’s its size now?
