Advantages
• Full multitasking with protected memory. Multiple users can run multiple
programs each at the same time without interfering with each other or
crashing the system.
• Very efficient virtual memory, so many programs can run with a modest
amount of physical memory.
• Access controls and security. All users must be authenticated by a valid
account and password to use the system at all. All files are owned by
particular accounts. The owner can decide whether others have read or write
access to his files.
• A rich set of small commands and utilities that do specific tasks well -- not
cluttered up with lots of special options. Unix is a well-stocked toolbox, not a
giant do-it-all Swiss Army Knife.
• Ability to string commands and utilities together in unlimited ways to
accomplish more complicated tasks -- not limited to preconfigured
combinations or menus, as in personal computer systems.
•
• The traditional command line shell interface is user hostile -- designed for the
programmer, not the casual user.
• Commands often have cryptic names and give very little response to tell the
user what they are doing. Much use of special keyboard characters - little
typos have unexpected results.
Disadvantages of UNIX
• The traditional command line shell interface is user hostile -- designed for the
programmer, not the casual user.
• Commands often have cryptic names and give very little response to tell the
user what they are doing. Much use of special keyboard characters - little
typos have unexpected results.
• To use Unix well, you need to understand some of the main design features.
Its power comes from knowing how to make commands and programs
interact with each other, not just from treating each as a fixed black box.
• Richness of utilities (over 400 standard ones) often overwhelms novices.
Documentation is short on examples and tutorials to help you figure out how
to use the many tools provided to accomplish various kinds of tasks.
unfortunately, this question is too subjective to answer correctly. each operating system has it's own advantages/disadvantages that would make it 'more suitable' for the specific requirement. in general, UNIX is considered 'more robust' while WINDOWS is considered 'less secure/stable'. WINDOWS is an 'operating system' that, historically used the 'processor chipset' provided by the INTEL corporation, 'evolved' from a 'local device only' operating system (MS-DOS) to a 'network capable' operating system (MS WINDOWS). UNIX is an 'operating system' designed 'from the ground up' to emulate the characteristics of the 'mainframe' computer system.

Information on the UNIX file system can be found in some magazines dedicated to technology such as Science Illustrated. Information can also be found on UNIX's official website.

When a user logs in to a Unix system, the current working directory normally starts at the directory/file
It is a system software and all the processes in the operating system can be controlled by the user.
The 'CD' command is not standard for Unix. The 'cd' command, however, will change directories (folders). It is a means of navigating the Unix file system.

The UNIX operating system consists of Regular Computer files. In addition there are listed file directory , symbolic link file, named pipe file, domain socket file, device file, and doors (computing) file.
