5 Purposes of an Operating SystemProvide User InterfaceCommunicate with HardwareCreate and Manage a File SystemNetwork SupportProvide Structure to Support Applications
Installation
PartitionsEvery 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
Active PartitionsThis is where the OS system files areMotherboard looks for the active partition
to begin running or booting the OSboot.ini is the file that windows uses to
declare where the systems are.
Extended PartitionDoesn’t hold an operating systemBasic DiscLogical Drives
Basically large named folders in the Extended Partition
Basic vs. Dynamic DisksUses NTFS or FAT32 file systemsCan create primary partitions or active
partitionDynamic Disk – unknown file system
(Microsoft won’t tell anyone how it works)
File SystemsNTFSFAT16FAT32
FAT16The Primary Partition can only be up to 2
GBFile names can only be 8 charactersFile extensions can only be 3 characters
FAT3232 GB Size Hard drives (Basically)Used mostly with Windows 98, 2000 and
some XPNo security available
NTFSNew Technology File SystemNice long file name and extensionsSupports file encryption (You still have to
have at least XP Pro)Most common file system used today
