Questions On Operating Systems Structure

You are asked to train her and as part of the orientation to Windows Server 2008, you decided to give her a background in the advantages of its file system. Create a short report that you can give her that summarizes the advantages you discuss in your training.

MANUAL INFORMATION STORAGE SYSTEMS – These are systems which do not use any computerised device. All data would usually be kept on paper in a manual filing system. The most common type of file used is a brown manila folder which would contain all documents fastened inside. Other types would be ring binders, lever-arc files and computer printouts which have been bound.

Well-organized file names and folder structures make it easier to find and keep track of data files. A system needs to be practical and used consistently. Without organization, you cannot report data effectively.

The different information systems are filing cabinets where hard copies are stores or electronically which can be saved changes can

Hard Disc Drive: a HDD is like a person's long term memory. it is used to store any type of data from files to applications. The data on a HDD is non-volatile, which means the data will stay on the disc even if the computer is switched off. A SSD is another way to store data, but it is faster than a HDD because there are no moving parts.

UNIX systems use to use flat files for storing data. Word processors and spreadsheet software can create flat files. Health Care facilities might use this type of data file for posting employee phone lists.

The first medium I want to cover is a hard-drive that is used inside computers and servers. A hard-drive can be broken up into different partitions, which sets up a volume with a single file system and a unique drive letter. These partitions of the hard-drive are kept track in a table called a partitions table. A hard-drive uses NTFS which breaks the drive into sectors of 512 bytes. These different sectors are stored

Function- responsible for storing all documents and data, including files, the operating system and more.

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

Filing systems are used to easily identify where documents and certain pieces of information have been stored, this makes it easier to retrieve for future use as it will limit the amount of time spent retrieving this information.

Partitioning strategy: The hierarchical partitioning of data into a set of directories – The placement and replication properties of directories is

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

A file refers to the visible unit of information contained within a paper or electronic folder .records are held in files to strengthen accessibility and identification

Q1: How is a file processing system or spreadsheet different to a database system? What disadvantages does the database approach address.

Databases allow us to easily store and retrieve data in a purely digital format. The strength of this is that large amounts of data can be stored and retrieved with minimal effort on the part of the user. Opposed to manually flipping through files, one can quickly pull up the requested data through a computer program. Many systems that were conventionally paper and file based have been converted to a digital format which are now stored in one or more databases.
