File Management Paper There are issues that arise concerning file sharing in a multiuser system, and that is access rights and the management of simultaneous access. Access rights to a file is granted unique users whether singular or grouped. A flexible tool is provided to allow extensive file sharing among the users while providing a number of options so that certain access can be harnessed or controlled (Stallings , 2012). Although a wide range of access is being used, there is still a list

handles this very differently. Let’s take a look at the differences between the three major operating systems and how they each manage its memory. We begin by analyzing UNIX/Linux. Linux, a form of UNIX, is very different in how it manages its memory to the other operating systems. Linux uses a tree like structure for memory management, and also using a numeric algorithm to make the best use of its valuable memory. The memory it manages is maintained in structures which enable protection of them by

File Management Nina N. Rountree POS 355 Terrence Carlson June 10, 2013 Operating systems that have numerous users with various security level clearances will require file protection. A UNIX operating system with 5,000 users could implement conventional UNIX file access controls if 4,990 of those users share the same level of security clearance. By means of a file access control structure on the UNIX operating system, each individual user is given a user ID (special user identification number)

File Management UNIX systems are based on the access control of files scheme which was introduced in the very early versions of UNIX. The way this works is that each UNIX user has an assigned unique user identification number which also puts this user ID into a primary group as well as other groups if the user ID needs it. These groups are identified, like the user’s ID, with a group ID. When a user creates a file, it is designated as owned solely by that user and marked with that user’s ID.

File Management Protection scheme File Management Protection scheme When considering a system that supports 5,000 users, wanting to allow 4,990 of those users to be able to access one file can be accomplished in many different ways. This paper will discuss two different options on how to complete this task. One of the ways that this task could be completed is to create an access control list with the name of all 4990 users. The second option will be to put the 4,990 user in one group and set
