Lesson 2

It is the type of disk in which the space is fixed. it doesn’t matter how much data you store.

20. You have purchased a new 72 GB disk drive and would like to format it in Vista with a single partition that uses up all the space on the drive. You can format the file system on the partition as (choose all that apply):

1.For 1 disk it takes 1 move to transfer 1 disk from post A to post C;

Ext3fs or third extended file system is a journaled file system that is commonly used by the Linux Kernel. It is the default file system for many Linux distributions.

List and describe at least three types of storage that is typically included in all computer systems.

23. Pg 312 Data Sharing. DAS – does not permit a second server to directly or simultaneously access it’s storage drives. Capacity sharing is like a viritualization of server storage.

Blocks are the logical records which breaks the area used by a partition; clusters are physical bodies of a hard disk. Hard disk is usually broken in to cylinders and cylinders are broken down in to clusters. Most HDD arrive from the factory with a low level pattern where, block size = 512 bytes. The NTFS file system can produce cluster sizes of a multiple of 512 having a default of 8 blocks for every cluster. Size of a block is multiple of size of cluster, such that a logical block will fit a definite number of physical clusters “one file one cluster”. That is, in every cluster will be installed information belonging at most to a single file. As an aftermath, when scripting a file in a hard disk, some cluster remains incompletely filled or fully unused. As the operating system can only write an entire block, it pursues that the idle space should be fit with some strings of bytes that can be used by others. It should be remembered that these data are saved in a disk because of the operating system curbs to write only on an entire block, they could be detected by locating

RAID 3 uses striping at byte level and the dedicated parity bits are stored in separate disk on the drive.

C. Permissions and Rights (What they can do. . Which operations they can perform on a system.)

10 direct disk addresses, maximum file has 128+10=138 blocks.so each block is 1 KB the largest file could be 138 KB.

For some computer owners, finding enough storage space to hold all the data they've acquired is a real challenge. Some people invest in larger hard drives. Others prefer external storage devices like thumb drives or compact discs. Desperate computer owners might delete

1. In Exercise 2, you used the Sharing and Storage Management console to create a simple volume. What must you do to create a different volume type such as a mirrored, striped, or RAID-5 volume?

Question 2 | Why does a warning appear when you select the ALICE1 (X:) drive, informing you that the X: drive is on the same physical disk as your system drive? Because X: drive is external storage. |

The more space you have the more files you can save, such as pictures, music, movies, etc.

Extensions are usually introduced as they have more advantages and these can be transferred to a new product, with the same attributes but in a different form.
