A computer file system described most simply is a process for organizing and storing computer data files. The file system, at the very least, must ensure that files are stored safely and are readily available for retrieval. At a minimum a file system must allow the operating system to write new files of data to the storage disk while at the same time protecting files previously stored, ensuring they do not get over written. And finally, a file system must make the stored files easy to find and quick to retrieve.
A discussion about Microsoft's file system requires a review of the history related to how these file system were introduced and the needs they were trying meet. The Microsoft operating systems have come to dominate the business and personal computer market. As they were beginning with their very first operating system it was necessary for them to develop a file system. And over the years Microsoft has changed their file system as Windows has become more complex and computer hardware becomes faster and more powerful. The changes Microsoft has made to its files system is charted below on the table below.
Microsoft's file system versions.
FAT12 Represents Microsoft's first file system introduced in 1977, it was provided with Microsoft's Disk BASIC
FAT16 Introduced in 1983 with the release of MS-DOS/PC-DOS 2.0
FAT32 Introduced in 1996 with the release of Windows 95's OEM Service Release 2
NTFS Introduced in July 1993 with the release of Windows NT 3.1
The name FAT is an acronym which stands for File Allocation Table and refers to a table or index listing of file names and clusters. This table is use to centralize the information used to identify which physical areas on the disk that are being used for file st...

...a page related to Windows Vista they go to great lengths to promote the advantages of NTFS.
"Some features that are available when you choose NTFS:
File encryption allows you to protect files and folders from unauthorized access.
Permissions can be set on individual files, as well as on folders.
Disk quotas allow you to monitor and control the amount of disk space used by individual users.
Better scalability allows you to use large volumes. The maximum volume size for NTFS is much greater than it is for FAT. Additionally, NTFS performance does not degrade as volume size increases, as it does in FAT systems.
Recovery logging of disk activities helps restore information quickly in the event of power failure or other system problems." (TechNet)
This same pages also provides a table below that describes the size and domain limitations of each file system.
Internal schema at the internal level to describe physical storage structures and access paths, typically uses a physical data model.
The next topic that is discussed is the topic of visual representations made by the computer such as pictures, so it speaks of how images are transferred into binary code and then reformed to create a rendering of the image. The resolution of this image is based on how many pixels the display has the more pixels the higher the resolution. The next point that of which the chapter speaks about is what happens to deleted data files. After data has been deleted the users think that it is gone. However, when data is deleted the blocks it is comprised of that are no longer part of any files are added to a “pool” of available disk blocks. This makes them accessible, if the binary code that formed the data was zeroed insead then they couldn’t be accessible. the data of the used blocks are saved to add these blocks to another file where to be reinstated into the computer in a data file. These blocks can be seen by anyone who has this knowledge, and these blocks can contain sensitive personal information that was deleted for a reason such as: account usernames, account passwords, bank account numbers, and
DFS promises that its system can be extended by adding more nodes to accommodate data’s growing. Also it can remove those not frequently used data from overloaded nodes to those light nodes to reduce network traffic. Scalability is the capability of a system, network, or process to handle a growing amount of work, or its potential to be enlarged in order to accommodate that growth.
Develop a common sense file-saving system where the location of files with specific purposes is very intuitive.
Not long ago computers were non-existent in many homes. When computers were first introduced to the world, they were for the sole purpose of performing business functions. The only people who owned computers were large organizations. Eventually, computers were introduced into the homes of those who could afford to buy them. Today, just about everyone owns some form of system that they use daily to help manage their day-to-day operations. What many once survived without now seems impossible to do without. As technology continues to grow, it has a greater effect on families and the education system. Some companies such as Microsoft and Apple made it possible to reinvent a new form of technology that would change the world. Each company had some form of struggle and overtime had to keep up with the changes of time and the way people communicated. From the first day of its invention, organizations have had to steadily implement new operating systems to keep up with the demands of the people while staying afloat with competitors. The ways of life for many have changed as well as the way people communicate. It is evident that the history and uses of computers have changed the world but these computers could not perform without the operating systems. Various operating systems will be discussed, how they began and how they each changed since they were first introduced. Although, they all had a purpose each varied in how they performed and changed the lives of many and will continue in the near future.
Windows based computers are more practical for many reasons. Possibly the most prevalent of these being that everybody uses them. When using computers consistency is very important. If everyone is using a certain operating system and software, it is easier to transfer, share, and use the data you create. Windows based systems are the standard in our community, and that is not due to change any time soon.
Due to the volatile nature of the computer memory, information might be lost or overwritten over time. The chip in the random access memory helps the computer to run its programs more efficiently by pulling the data from the RAM. However, every time a machine is switched on, some data stored in the RAM is lost. Whereas the data stored on the hard drive is known as persistent data, the RAM is known as volatile memory. The RAM is constantly swapping the rarely used data that is the hard drive to create space for new information. Therefore, the longer the investigators wait, the more likely they will lose the incriminating data since the computer is not indefinitely persistent. It is fortunate that the investigators have found ways to preserve the evidence without necessarily switching on the computer. The contents are used in courts as the lawyers can use them as evidence for criminal activity.
As the internet is becoming faster and faster, an operating system (OS) is needed to manage the data in computers. An Operating system can be considered to be a set of programed codes that are created to control hardware such as computers. In 1985 Windows was established as an operating system and a year earlier Mac OS was established, and they have dominated the market of the computer programs since that time. Although, many companies have provided other operating systems, most users still prefer Mac as the most secured system and windows as it provides more multiple functions. This essay will demonstrate the differences between windows
File servers are an important part of any business. The file server is the central location of files for a business small or big. The file server can be a cloud accessible server which grants accesses anywhere. The file server can also be a dedicated server which is only used on the business network. I am going to touch on the specifications of a file server. This means I am going to go over CPU, memory, bus, DMA, storage, interrupts, input/output peripherals, and monitors of a files server.
...e user while using the software applications. This could be word processor documents, spreadsheets, presentations, web pages or game save files. It is important to keep this data secure, as it could include important information such as customer details, employee payroll data or financial information. There are huge amounts of user data stored by businesses that are absolutely vital to the running of the business.it is therefore extremely important to keep a copy of this data that is currently stored on the system.
In the electronic storage system files should be saved in a proper place and secured. The paper documents which need to be stored in an electronic system should be scanned at first, then the paper copy filed or shredded. To retrieve the information, the person who requested
The second reason is that users often accidentally remove files that they later need again. This problem occurs so often that when a file is "removed" in Windows, it is not deleted at all, but just moved to a special directory, the recycle bin, so it can be fished out and restored easily later. Backups take this principle further and allow files that were removed days, even weeks ago, to be restored from old backu...
...text files and spreadsheets, cloud storage will be very beneficial. Using it as backup for these types of files is a major plus. Internet connection speed is not an issue and almost anyone has easy access to the files.
