File Management (Option 1) Access Rights is an accommodating tool that can be used to allow users on a network to file share (Stallings, 2015, p. 541). In most systems, users and groups of users have a certain granted access to files. There are many different access rights that can be assigned and are assigned based on the level of the user. Specifying which users can access one file in a system being supported by 5,000 users can be done by creating an access control list with the names of the 4,990 users who need access. Another way to allow the 4,990 users to access the files would be to put them all in one group and set the group access level accordingly. An access control list specifies which users are granted or denied access to certain files, and can be granted to individual users, or groups (Stallings, 2015, p. 525). In most multiuser systems, access control is enforced, and only certain users are allowed access and to perform certain actions on certain files. Access control information may include the owner, access information, and permitted actions. The owner is the individual who has control over the file, and who can grant or deny access to other users. Access information includes each of the user’s name and password. Some permitted actions that can be granted to users include reading, writing, executing, and transmission over a network (Stallings, 2015, p. 537). The owner of the file can grant all of these actions.
When granting 4,990 users access to one file another way is to group the users and grant privileges to an entire group. User groups are a set of users who are not individually defined, but need to be kept track of through the system (Stallings, 2015, p. 541). While this protection scheme can be useful, it cannot always be applied since the system restricts user groups (Stallings,

...PROCEDURES FOR CONDUCTING PRACTICAL ICT TESTS The Supervisor A suitably competent supervisor, who may be the candidates’ tutor, is responsible for the administration of the practical tests according to these instructions. The supervisor is responsible for the preparation of the hardware and software for the test. Timetabling of the Practical Tests CIE does not timetable the practical tests in the same way as most IGCSE and AS & A Level written papers. The IGCSE and AS & A Level timetable will specify a period within which candidates must take the two practical tests for each syllabus. Within this period, Centres may conduct the practical tests at any convenient time or times. Candidates must complete each practical test in a single session. Wherever possible, candidates from the same Centre should sit their assessment at the same time. If more than one session is necessary to accommodate all candidates, these sessions should follow on from each other. However, Centres do not need to sequester candidates until other candidates have taken the test. When arranging examination dates, Centres should take into account the time needed to set up the system and should allow contingency planning (e.g. to reschedule examination times due to possible hardware failure) wherever possible. Preparation for the Practical Tests Before the candidates take a practical test, the supervisor must work through a past/specimen paper, using the hardware and software that the candidates will be using...

An Analysis of Ecb

...This customer data file is for 60,000 customer records in the restaurant category. Clean up the data: As with most customer data files, there is incomplete information. Address how you handle incomplete data. (I suggest completely eliminating records in Acquisition Channel with “NULL” or “Uncategorized”.) Also eliminate any records with blank in Ethnicity. Note in Ethnicity African-Americans is also coded as Afr. Am. so these two should be combined. In Age of Kids there are cells coded as Pre-teen &? I suggest combining with “Age Mix” or “Preteen & Teenagers”. After cleaning up the file, we are left with 26,352 records which should still be an adequate sample size.) Questions for analysis: 1. Calculate the profitability of each customer. Assume the average Cost of Goods Sold (COGS) for all vouchers (with promotional discounts factored in) is 20% of the total revenue. Assume the average one-time Cost per Acquisition (CPA) for each channel is: $12 for Advertising, $10 for Affiliate, $5 for Email, $8 for ILS, $7 for Paid Search and $5 for Social Media. Assume there are no additional costs. You may find the Excel VLOOKUP function helpful for this (https://support.office.com/en-sg/article/VLOOKUP-function-0bbc8083-26fe-4963-8ab8-93a18ad188a1). 2.

Introducing Transaction Log Files

...Introducing Transaction Log Files Each SQL Server 2000 database has at least one transaction log file and can have multiple transaction log files spread across a number of disks. Each transaction log file is a separate operating system file and is used by only one database. Each transaction log file generally has the .ldf filename extension (this extension is not required). Each transaction log has a logical filename that is used in Transact-SQL statements and a physical filename that is used by the Windows operating system. Additional file properties include the file ID number, initial file size, file growth increment (if any), and maximum file size. Unlike data files that contain pages, transaction log files contain a series of transaction log records. A sequential log sequence number (LSN) identifies each transaction log record. Regardless of the number of physical log files, SQL Server 2000 treats the transaction log as one continuous log. SQL Server 2000 logically divides each physical transaction log file into a number of virtual log files (VLFs). The number and size of virtual log files are determined dynamically based on the size of each transaction log file. Each transaction log file has at least two VLFs. Each growth increment (if any) is treated as a separate physical file with its own VLFs. The number or size of VLFs cannot be configured or set directly by the database administrator. SQL Server 2000 tries to maintain a small number of virtual file logs because it operates...

Case Project

...Running head: Case Project Case Project Student College Case Project Linux as an operating system is a powerful tool used in businesses for its secure kernel and command line interface. From a small business to a large enterprise, Linux is used to run servers, store vital information and documents. In Outdoor Adventures, this store needs a more efficient computing system. The system will need to keep information available and secure enough to ensure that the information can only be seen by the right people. To help keep things organized, a file structure will also be required to keep all the files with special permissions together for easy access. To better illustrate the security capabilities of Linux Ed Sawicki of Biznix.org said, “The Linux firewall has functionality that rivals expensive commercial firewalls. Its rules allow fine grained control over stateless and stateful packet filtering. The Linux firewall is extensible, allowing new filtering capabilities as the need arises.” This comparison is powerful when considering what would be the most cost effective direction for a business, but also the safest. Another advantage of linux is that it is generally free to try before applying it to a commercial setting. The product can in effect speak for its self by allowing itself to be made publicly available so there is no need to consider it a “business risk” when a technician can experiment with it first before applying it on a much grander scale. “Linux…is...

File Access

...File Access Computers have become an important tool for the companies. They are used as time clocks, keep track of inventory, to communicate with customers and to do research. In some cases, the computer is used to assign tasks and inform employees of upcoming events. Though computers are good tool and resource, there is the potential an employee may misuse or access files they have no clearance to access. For this reason there is a need to restrict access. If a company has 5000 employees who have access to the computer system and there is a need to restrict 10 users from accessing a specific file, there is a need to establish protocols to prevent access. How this is done differs in each operating system. In Unix there are ways to set parameters for the 4990 users to access a single file. These are set within the types of files. They are called regular, directory, special, named pipes, links and symbolic links. Unix operating systems operate these files and routes them into a uniformed system that operates in the background supporting files and giving disk space as needed for files. This is done by using inode (Index node) which controls information the system needed for a specific file. Multiple files can be connected to one inode, but if active the inode will only be associated with one file and a file will be controlled by one inode. A file’s attributes, permissions, and control information are stored within the inode. In the FreeBSD inode for example has...

Pos 355 File Management

...File Management Comparison for Operating Systems All computers and their subsequent operating systems use a means of digitally storing data within a file onto an allotted section of some type of storage media. The allotted section of storage can theoretically be read from, and written to as required. The data in the file is stored as bytes of binary code, and can be identified as belonging to a particular file by the file’s start or “address”. Though the storage section is linear in nature, it can be visualized as a cross grid of cells, with each cell containing one byte of data. The combined cells of data populate the allotted section of storage within a file. At this point, operating systems diverge from this commonality, particularly in the way the operating systems manage files through their respective “file management” programs. The following is a cursory look at three such operating system’s file management schemes. Mac OS file system Mac OS uses what is called the Hierarchical File System (plus). It comes from the original version of the Hierarchical File System (HFS), which comes from the Macintosh File System (MFS), used with older Mac systems. The HFS concept begins with a sole directory on a storage media (in this case a hard drive or hard disk). From this directory, sub-directories are created, and so on, down to the user and user access files. This is the most simplistic of file management system concepts, in theory. Mac OS is also proprietary. Linux...
