List the 7 basic file attributes associated with a file in operating systems.
1 ) Name : Each file has his own file name assosciated within the file sytem, No two Files in the same directory will have the same file names.
2 ) Identifier : Each file has extensions for an example .txt, .pdf, etc...
3 ) Type : File are divided into different types like Audio, Video, Text etc...
4 ) Protection : Each file has its own file permission like read, write and execute permissions which is used through chmod command, using these command we can change the permissions
5 ) Size : In a fileSystem there will be size of each file calculated by number of bytes in memory
6 ) Location : There are many locations where file can be saved, each file has its own set of loaction
7 ) Time and Date : In the file system each file has timestamp of time and date where its last modified

IT 241 operating Systems: What is file-allocation table (FAT) and what is free-space list ?
List the information stored along with files, such as creation date, modification date, or file attributes. Describe some of the more common networking devices used to provide connectivity and discuss the basic differences between the devices. Discuss how to organize files and directory structures to provide efficient access and include for permission controls. Determine how much space you have on the hard disk. What is the capacity? How much space is free? How much space is used? Suppose you create...
Discuss the key architectural design implications normally associated with a decision to use local systems as opposed to a central heating-cooling system. List and describe five (5) attributes that you associate with use of a local system and five (5) attributes that you associate with use of a central system.
Why do some operating systems support specific types of file structures and why do some operating systems don’t?
Systems Architecture 7--> By default, what do most file management and operating do when a user deletes a file? A) mark the storage allocation unit as free and the directory entry as unused B) overwrite all allocated storage with spaces or other null content C) Remove the entry from secondary storage D) Mark the directory entry as used 8--> Linux file access control types include________ A) read, write and change B) read, modify and list C) read, write and execute...

Computer Science: Operating Systems - (File-System Interface) Some systems automatically delete all user files when a user logs off or a job terminates, unless the user explicitly requests that they be kept; other systems keep all files unless the user explicitly deletes them. Discuss the relative merits of each approach.
Discuss the essentials of file recovery in the three major operating systems i.e. Windows, Macintosh, and Linux. Discuss how to recover information from damaged media.
Operating systems in C
15.) Suppose a program has successfully opened a file object, fp, for reading a file from a disk drive and the program has created a buffer, my-but, of an appropriate size. Consider the following C function call. fread (my_buf, 1, BUFFERSIZE, fp); a) Explain why this function call may, or may not, cause a system call to the operating system. b) Suppose that the above function call causes a system call. Explain why the operating system...
