  1. Installing OS

  2. Objectives • Introduction • Understand partitioning • Understand file systems • Understand mounting • Understand administrator and root

  3. Introduction • When you just buy a new computer, you cannot use that computer to perform your daily task such as: Office work, Graphic Design… • To use that computer to perform your daily work you need to install an operating system • For installing an operating system you need to know: • Partitioning • File System • Mounting Partition • Administrator and Root User

  4. Objectives • Introduction • Understand partitioning • Understand file systems • Understand mounting • Understand administrator and root

  5. Understanding Partitioning • Disk partitioning is the act of dividing a hard disk drive into multiple logical storage units. • There are two types of partition • Primary partition • Extended partition • In one hard disk you can create four primary partitions or three primary partitions and one extended partition with many logical drives.

  6. Understanding Partitioning C: C: Primary partitions D: D: E: E: F: F: Extended partition with logical drives G: -OR- H:

  7. Understanding Partitioning • Swap also known as page file: Swap space is used by OS when the amount of physical memory (RAM) is full. If the system needs more memory resources and the RAM is full, the unused data in memory are moved to the swap space. • There are two types of swap: swap partition and swap file. • Swap partition: is an independent section of the hard disk used solely for swapping; no other files can reside there. • Swap file: is a special file in the file system that resides amongst your system and data files.

  8. Understanding Partitioning • RAID (an acronym for redundant array of independent disks; originally redundant array of inexpensive disks) is a storage technology that combines multiple disk drive components into a logical unit. • Data is distributed across the drives in one of several ways called "RAID levels“ (RAID 0, RAID 1, RAID 5…). • There are two type of RAID: Hardware-base RAID and Software-base RAID.

  9. Understanding Partitioning • Software-base RAID: Now software RAID can be implemented by many operating system. • Hardware-base RAID: A RAID is considered hardware-based when it is implemented in hardware, either on the motherboard directly or a separate RAID card. Windows views the entire RAID as a single disk. The individual component disks are controlled by the RAID controller and not directly accessible to Windows. • In some computers such as servers that have hardware RAID, you need to configure RAID level before you install OS.

  10. Objectives • Introduction • Understand partitioning • Understand file systems • Understand mounting • Understand administrator and root

  11. Understanding File system • In a computer, a file system (sometimes written filesystem) is the way in which files are named and where they are placed logically for storage devices. • There are many types of file systems such as EXT2, EXT3, EXT4, FAT, NTFS… • There are some file systems that Linux support natively: Ext2, ext3, ext4… • There are some file systems that windows support natively: FAT, FAT32, NTFS…

  12. Objectives • Introduction • Understand partitioning • Understand file systems • Understand mounting • Understand administrator and root

  13. Understand mounting • In order to access a file system in your OS, you first need to mount it. Mounting a file system means making the particular file system accessible at a certain location in the OS. • On some OS this operation is automatic. • When mounting file systems, you need to know the device name associated with the particular storage device and the location you would like to mount it to.

  14. Objectives • Introduction • Understand partitioning • Understand file systems • Understand mounting • Understand administrator and root

  15. Understand administrator and root • Each Operating System always has special user accounts used for Systems Administration. Depending on the operating system, the actual name of this account might be: root, administrator. • root is the conventional name of the user who has all rights or permissions (to all files and programs) in whole systems. • Administrator account is to allow making system-wide changes to the computer.

  16. Practice • Install four OS • First install the OS in scenario from Lesson 1 • Then install other OS such as: Ubuntu, Red Hat, Open SuSE and Windows 7.
