 5.1 Modern Operating System

 (^) Explain operating system requirements.

 5.2 Operating System Installation

 (^) Install a Microsoft Windows operating system.

 5.3 Chapter Summary

Modern Operating Systems

Operating System Terms and Characteristics

 Terms

• (^) Common terms describing operating systems include: multi-user, multitasking, multiprocessing and multithreading

 Basic Functions of an Operating System (OS)

• (^) Hardware Access
• File and Folder Management
• User Interface (CLI and GUI)
• Application Management

 Processor Architecture

• (^) Affects the performance of the computer.
• CPUs contain storage locations called registers.
• Registers can be 32-bits or 64-bits long.

Modern Operating Systems

Types of Operating Systems

 Desktop Operating Systems

• (^) Intended for use in SOHO environment.
• (^) Supports a single user.
• Shares files and folders on a small network with limited security.
• Microsoft Windows, Apple Mac OS, and Linux are a few examples.

 Network Operating Systems

• Contains features that increase functionality in a networked environment
• Supports multiple users.
• Provides increased security compared to desktop operating systems

Modern Operating Systems

Operating Systems Upgrade

 Checking OS Compatibility

• (^) New version of an OS brings new functionality and better performance.
• (^) Support for older hardware may be dropped.
• New hardware may require latest OS versions.
• Make sure to check OS compatibility before upgrading the OS.
• Microsoft’s Upgrade Assistant and Upgrade Advisor can be helpful tools.

 Windows OS Upgrades

• (^) Upgrading Windows may be faster than performing a full install.
• (^) The installed version of an OS determine the upgrades options.
• A full data backup is strongly recommended before upgrading.

 Data Migration

• User data must be transferred after a new installation.
• (^) User State Migration Tool and Windows Easy Transfer are tools designed to help the transfer process.

5.2 Operating System

Installation

Operating System Installation

Storage Device Setup Procedures (Cont.)

 OS Installation with Default Settings

• (^) The installer program applies the most common settings.
• (^) Preferred by inexperienced users.
• Allows for very little customization.
• Windows allows for granular customization after the default setting installation is complete.

 Account Creation

• User accounts allow multiple users to share a computer.
• (^) Common Windows account types are Administrator, Standard, and Guest.

 Finalize the Installation

• (^) Use Windows Update to check for updates after the installation is complete.
• Use Device Manager to verify that all hardware was properly installed.

Operating System Installation

Custom Installation Options

 Disk Cloning

• (^) Good solution to speed up bulk installations
• (^) Uses a single OS installation as base system to create multiple clone systems.

 Other Installation Methods

• Windows has several different types of Custom Installations including network installation and image-based installation.
• Other types of Custom Installations include Windows Advanced Startup Options, Refresh your PC (Windows 8.x only), System Restore, Upgrade, Repair installation, Remote network installation, Recovery partition, and Refresh/restore.

 Network Installation

• (^) Relies on a network connection to deploy the installation files.
• Network Installation methods include Remote Network Installation and Unattended Installation.

Operating System Installation

Boot Sequence and Registry Files

 Windows Boot Process

• (^) Common boot steps are: POST execution, locating and loading CMOS configurations, locating and loading bootloaders, locating and loading the OS.
• Windows Boot Loader and Windows Boot Manager are programs used to manage Windows startup.

 Startup Modes

• (^) Windows Startup Modes allow for troubleshooting when Windows fails to start.
• (^) Windows Startup Modes include: Safe Mode, Safe Mode with Networking, Safe Mode with Command Prompt and Last Known Good Configuration.

 Windows Registry

• (^) All Windows settings are stored as key-values pairs in the Windows Registry
• (^) Extreme caution must be taken when working with the Registry.

Operating System Installation

Multiboot

 Multiboot Procedures

• (^) It is possible to install multiple OSs in one computer.
• (^) BOOTMGR manages multiple versions of Windows installed on a single computer.

 Disk Management Utility

Many tasks can be accomplished through Disk Management Utility, including: view drive status, extend partitions, split partitions, assign drive letters, add drives and add arrays.

 Partitions

• Logical divisions created inside a drive to host file systems.
• Partitions can be extended or shrunk using the Disk Management Utility

 Drive Mapping or Drive Letter Assignment

• (^) In Windows, assigning letters to name physical or logical drives is called drive mapping or drive letter assignment.
• (^) Disk Management Utility can also be used to manage drive letter assignment.

Operating System Installation

Disk Directories (Cont.)

 Attributes

• (^) File extensions identify file types in Windows and must adhere to Windows Naming Convention.
• (^) File attributes define how files can be handled.
• (^) Common file attributes are READ, ARCHIVE, SYSTEM and HIDDEN.

 Application, File, and Folder Properties

• Right-click on a file, application or folder to see its properties.
• Application and File Properties are different than Folder Properties.
