Windows also uses process ids to manage processes

This preview shows page 8 - 11 out of 15 pages.

Windows also uses process IDs to manage processes however it not as readily available to the user in the Task Manager as it is in the Activity Monitor. By default the process ID is not display, but a user can manually display the process ID through one of the settings in the Task Manager. The command line can also be used much like the shell and bash but with different

The taskkill command is used to terminate processes like the kill command.File ManagementFile management refers to the management, organization, and manipulation of documentsand the data in files on a computer. An end user can create a new file, edit an existing file, view, save, or even delete a file. They can also open or load a pre-existing file into the memory and or close a file without even saving it. End users can easily manage and organize their files by grouping related files in directories. A file management system is that set of system software thatprovides services to users and applications in the use of files. Typically, the only way that a user or application may access files is through the file management system (Stallings, 2012). However, the processes of file management are accomplished in different ways in different operating systems.All of UNIX and Linux data are organized into files and all files are organized into directories. The hierarchical structure supporting a directory and sub-directory structure can be basically view as an upside down tree like structure. The file structure starts with the root that represents by a forward slash (/). Under the root are sub-directories and these sub-directories arecapable of having their own sub-directory sub-division. Unlike Windows file system, UNIX/ Linux and Mac do not have drive letters names in the path to the file or backslashes, they use a similar item called mount points. Linux uses what they call a hard links and symbolic links to the files. Hard links cannot connect to a directory so the end user has to generate a symbolic link.This is much like how Windows uses shortcuts. The Mac file system is also considered as a hierarchical structure and like UNIX/Linux it also uses the forward slash (/). Windows file system can have many hierarchies, one for each partition and also one for each network drive.
UNIX/LINUX VERSUS MAC VERSUS WINDOWS ROUGH DRAFT10The two structures that can be found in Windows are Windows NT File System (NTFS) and File Allocation Table (FAT).There are three basic files types for UNIX, ordinary files, directories, and special files. Ordinary files contain data, text, or program instructions. Mac is based on UNIX and also has the same files types. Directories stores both ordinary files and special files similar to Windows, they are equivalent to folders. Special files are files that provide access to hardware such as Ethernet adapters, hard drives and CD-ROMS and other special files.
