1. Operating Systems Review

2. 5 Purposes of an Operating System
Provide User Interface
Communicate with Hardware
Create and Manage a File System
Network Support
Provide Structure to Support Applications

3. Installation

4. Partitions
Every disk needs at least 1 partition to install an operating system
Formatting a partition will allow you to install an operating system (NTFS, FAT16, etc)
Max Number of Partitions on Basic Disc is 4!
Primary and Secondary Partitions
Active Partitions

5. Active Partitions This is where the OS system files are
Motherboard looks for the active partition to begin running or booting the OS
boot.ini is the file that windows uses to declare where the systems are.

6. Extended Partition Doesn’t hold an operating system Basic Disc
Logical Drives
Basically large named folders in the Extended Partition

7. Basic vs. Dynamic Disks Uses NTFS or FAT32 file systems
Can create primary partitions or active partition
Dynamic Disk – unknown file system (Microsoft won’t tell anyone how it works)

8. File Systems
NTFS
FAT16
FAT32

9. FAT16 The Primary Partition can only be up to 2 GB
File names can only be 8 characters
File extensions can only be 3 characters

10. FAT32 32 GB Size Hard drives (Basically)
Used mostly with Windows 98, 2000 and some XP
No security available

11. NTFS New Technology File System Nice long file name and extensions
Supports file encryption (You still have to have at least XP Pro)
Most common file system used today
