What is the use of time-sharing in unix?
Time-sharing is designed so that rapid switching between tasks allows the users to believe they have sole use of a scarce resource (CPU). If there is only 1 CPU present then only 1 task can run at a time.
With rapid switching it occurs so quickly that it appears as though multiple jobs (tasks) are being serviced.
The companies that use Unix are the companies that require certain Unix-only programs to execute, or companies that support Unix applications for other clients. You may find that the companies that use Unix are the same companies that might use Microsoft Windows, for example. It is just a different technology for solving problems. Read More

I am currently using windows XP2. For practice purpose i want to use UNIX shell scripting. Without installing UNIX OS how can i use the UNIX shell scripting?
You should be able to download the Unix Services for Windows, version 3.5, from Microsoft (free). There are other shell emulators that are available for Windows, which would allow you to use Unix type shell scripting without installing any additional OS.

The usual difficulty that people report concerning UNIX is the use of the command line. The command line has a lot of power and the commands may seem somewhat arcane at times. Like anything else, you have to study what the commands do and how to use them to harness the power of UNIX, but once you do that it isn't that difficult to use. Read More

The simple answer is that Unix does not use extensions for program associations. Everything in Unix is a file, whether it is a device, a data file, or a program. In Unix it is controlled by permissions, primarily the execute permission. Also, by checking the first block of a file for its content we can determine what program to use with a file (usually in a graphical mode). Read More

Pine is a third-party software package that does not come with Unix or Linux; it has to be installed. It was written for a beginner in mind so that they didn't have to know a lot about the Unix environment when using mail.

There are two standard job schedulers in Unix - 'at' and 'cron'. Neither can be answered in a short answer so it is suggested that you do an internet search on either of these two commands, or use the 'man' or 'info' command on 'at' or 'cron' on your Unix/Linux system. Read More
Too difficult to answer here. I would find the source code and use that (if you really had to). Might require a 'port' to another operating system if it wasn't Unix based. Read More
