LINUX & UNIX FAQS & ANSWERS  IN INDIA

What is LILO? LILO is a boot loader for Linux. It is used mainly to load the Linux operating system into main memory so that it can begin its operations. 6) What is a swap space? A swap space is a certain amount of space used by Linux to temporarily hold some programs that are running concurrently. This happens when RAM does not have enough memory to hold all programs that are executing. 7) What is the advantage of open source? Open source allows you to distribute your software, including source codes freely to anyone who is interested. People would then be able to add features and even debug and correct errors that are in the source code. They can even make it run better, and then redistribute these enhanced source code freely again. This eventually benefits everyone in the community. 8) What are the basic components of Linux? Just like any other typical operating system, Linux has all of these components: kernel, shells and GUIs, system utilities, and application program. What makes Linux advantageous over other operating system is that every aspect comes with additional features and all codes for these are downloadable for free. 9) Does it help for a Linux system to have multiple desktop environments installed? In general, one desktop environment, like KDE or Gnome, is good enough to operate without issues. It’s all a matter of preference for the user, although the system allows switching from one environment to another. Some programs will work on one environment and not work on the other, so it could also be considered a factor in selecting which environment to use. 10) What is the basic difference between BASH and DOS? The key differences between the BASH and DOS console lies in 3 areas: – BASH commands are case sensitive while DOS commands are not; – under BASH, / character is a directory separator and / acts as an escape character. Under DOS, / serves as a command argument delimiter and / is the directory separator – DOS follows a convention in naming files, which is 8 character file name followed by a dot and 3 character for the extension. BASH follows no such convention.
