7.Explain the process of installing and configuring application software.
Ans.
1. Installing a software basically means copying a set of code in specific directory from which system can access those files for compilation and execution.

 2. New software packages might be installed in ‘/opt’ if they are likely to be upgraded separately from Red hat distribution itself.

 3. Some packages may need to go in ‘/usr/src’ or even ‘/usr’ if they are upgraded of packages installed as part of packages installed as part of Red hat.

 4. The location of the installation usually matters only if you compile the application from source code.

 5. If you use a Red hat package manager (RPM) application package, it automatically goes where it should.

 6. It is possible for individual users to install some applications in their home directories.

 7. Drive space set aside for their own files and customizations, these applications may not be available to other users without the permission of the user who installed the program or the system administrator.

8. Besides system administrator can decide which users may use which application by creating a ‘group’.

Explain memory and virtual file system in Linux.

22.Explain memory and virtual file system in Linux. Ans. 1. These file systems do not exist on disk in the same way that traditional file systems do, they either exists entirely in the system memory or they are virtual because they are an interface to system devices. 2. cramfs: cramfs is designed to cram a file System onto a small flash memory device, so it is small, simple and able to compress things well. The largest file size is 16MB and the largest file system size is 256MB since cramfs is so compressed, it isn’t instantly updateable. 3. tmpfs: tmpfs is structured around the idea that whatever is put in the /tmp file system is accessed again shortly, tmpfs solely in memory, so what you put in /tmp doesn’t persist between reboots. 4. ramfs: ramfs is basically cramfs without the compression. 5. romfs: This is a read only file system that is mostly used for initial ramdisks of installation disks. It was designed to take up very little space, so you could fit a ke...
