Operating System
The operating system (OS) is the bridge connecting
your computer hardware to the software
applications.
The OS provides a consistent set of rules for
applications to use in order to interface with the
hardware.
The OS manages all of the software and hardware on
the computer.

Identifying OS Versions
A specification that defines a new model for the
interface between personal-computer operating
systems and platform firmware.
A replacement for the legacy BIOS that provides a
standard environment for booting an operating
system and running pre-boot applications.
You can use a mouse!
Manufacturers can easily customize it. Very cool, but
this also means that almost every one of them
differs.

Comparison of Home, Premium,
Professional, and Ultimate
 The process of setting an electronic device to operate at
frequencies higher than originally intended.
 Many motherboards, CPUs, GPUs, and memory modules
support overclocking.
 CPU Overclocking (OC) is the most common.
 Chipset and RAM OC are also very common.
 GPU OC is often done from within the OS not the BIOS or
UEFI.

32-Bit vs 64-Bit Processing
32-bit and 64-bit refer to the way the computer’s
CPU processes data
 32-bit processing means 32 bits of data can be
processed at a time
 64-bit processing means 64 bits of data can be
processed at a time

32-Bit vs 64-Bit
32-bit (x86) can use up to 4 GB RAM and support up
to 32 processor cores
64-bit (x86-64) can handle as much RAM as the
motherboard will allow and can support up to 256
processor cores

Windows 7 Suggested System
Requirements
 Internet access
 Depending on resolution, video playback may require additional memory
and advanced graphics hardware

Full vs Upgrade Version
Most Operating Systems are available in a full version
or an upgrade version
A full version is installed on a clean hard disk
An upgrade version is used if your computer is
currently running a Windows Operating System
*Verification of compatibility must be ensured

16
Upgrade Terms
Upgrade path – operating systems needed to
upgrade from one version of Windows to another
When moving to Windows 7 from Windows Vista
you have two primary choices:
 Standard upgrade
 Custom installation
Windows XP users must perform a custom
installation when “upgrading” to Windows 7

17
Upgrade Terms
Standard Upgrade – replaces your current version of
Windows with the new version while retaining your
files, settings, and programs; also referred to as an
“in-place” upgrade
Custom Installation – replaces your current version
of Windows with the new version but overwrites
your files, settings, and programs; also referred to as
a “clean” installation

18
Upgrade Paths
When having to perform a custom installation be sure
to do the following
 Backup all data files
 Verify access to original installation media of all
programs you plan on installing after upgrading
to the new OS
 Acquire drivers for all hardware

Other Upgrading Options
To upgrade from Windows 95, Windows 2000, Linux,
UNIX, or Mac OS a full version is required and a full
custom installation is required
Upgrading from an existing Windows 7 version is also
possible

Upgrade Advisor
A preparation tool that checks your computer’s
hardware, attached devices, and installed programs
for compatibility issues
Creates a report that lists potential issues
Provides suggestions for which version will work best
for your system

Application Compatibility
Windows 7 Compatibility Center - provides software
programs, updates, downloads, drivers, and more
that are compatible with Windows 7
Browse this site before upgrading to Windows 7
Use this site to research software issues you

you’re upgrading to a different version of Windows
that requires a custom installation
By transferring your files and settings, you get a jump
start on your productivity
