NTFS (New Technology File System) It is a file system that was designed specifically for Windows NT and is compatible with other versions of Windows, Windows 2000, Windows 2003, Windows XP and Windows Vista) It is based on a structure called "master file table" or MFT, which You can get detailed information in the archives A file system is basically the structure that works with a partition on a disk where data can be stored. Format is the process in which a file system is assigned to a partition
In Windows there are two types of file systems: -FAT and FAT32 At first they were developed only for Windows, although they are compatible with Linux. This type of format has also been used in memory cards and other devices. This system could be said to have a main drawback: There is no possibility to work with files larger than 4 GB and also does not support partitions that exceed 32 GB.
- NTFS The general scheme of an NTFS system would be as follows: Partition Boot Record MTF System files File Area Boot partition record: The volume information (partition type) and the basic code that allows access to the operating system are stored here. MTF: The master table. Here you specify Where and How the files and their attributes are stored. System Files: Contains information about the exercises that occur in the file system. File Area: Location where user data is stored. Unlike the FAT system it is able to operate with much larger size partitions, up to 256TB. Although, it is true, it is not recommended that in practice exceed 2TB.
Advantages of the NTFS system: -The performance on an NTFS partition is higher than a FAT partition, since file access is much faster because it uses a high-performance binary tree. - As for its level of security it is remarkable that it is possible to define different attributes for each file. This allows you to use encryption and permissions to restrict access to users who do not have the necessary approval granted by the owner of the file. - They have a feature called "compressed" that allows NTFS files to be saved compressed to save space.

Like the FAT system has a handicap: To carry out the management of the files it is necessary to have a large amount of space on the disk, it is not recommended to use in a system with less than 400 MB free, therefore It is not recommended for partitions less than 10 GB. You must differentiate the permissions of the folders with the permission of the files. When assigning an NTFS permission to a folder or a file it is mandatory to be the administrator or owner or, in its absence, to have the necessary permissions to be able to have control over them.
MAC OS From the English Macintosh Operating System. It is the operating system that was created by the company Apple Computer Ic. It started working on their Macintosh computers. It was the first system that had a graphical user interface aimed at the general public. It was based on the Lisa OS system, the system installed on the Apple computer that had the same name and used some criteria of the Xerox Alto. The launch of the Mac operating system is a before and after in terms of functionality. At that time the way of working with the computer was through text commands. But Apple with the creation of its new graphical interface allowed that it could handle the mouse, navigating through a menu with icons and windows, Which greatly facilitated its usability. The main drawback of this system is its compatibility, only works on Mac computers, which greatly limits its use. Other systems such as Windows are compatible with clone computers.
The first version of this operating system stood out among other systems of the time, being pioneer for example in creating an application that was used to manage files, Finder. It also came from the Desktop and all these applications were stored in a System Folder. The team responsible for Macintosh design consisted of George Crow, Burrel Smith, Andy Hertzfeld, Joanna Hoffman, Bill Atkinson and Jerry Manock. Among them was the work of Andy Herttzfeld, in charge of writing the original Macintosh software system, the Control Panel, and the Scrapbook.
Its first version came to light on January 24, 1984, with the name Mac OS. Until version 9 of the system its development was based on a progressive model. In 2001 Apple decides to give a change to its operating system using as UNIX model, it arises in this way Mac OS X. From here the different versions that were released until 2003 were baptized with names of felines. The main features of Mac OS X is that it is a multitasking and multiuser system and it is proprietary software.
