Answers (100% Pass)
In which language is Linux written? What does the language have to do
with the success of Linux? - Answer✔️✔️-More than 95 percent of the Linux
operating system is written in the C programming language, and C is
portable because it is written in a higher-level, machine-independent
language. (The C compiler is written in C.)Because Linux is portable, it can
be adapted (ported) to different machines and can meet special
requirements.
What is a shell? How does it work with the kernel? With the user? -
Answer✔️✔️-In a textual environment, the shell—the command
interpreter—acts as an interface between you and the operating system.
When you enter a command on the screen, the shell interprets the
command and calls the program you want.
Where on the disk should you put your /boot partition or the root (/)
partition if you do not use a /boot partition? - Answer✔️✔️-Put /boot at the
beginning of the drive (partition 1) so that there is no issue
of Linux having to boot from a partition too far into the drive.
When might you specify an ext2 filesystem instead of ext4? - Answer✔️✔️-
Use ext2 for partitions whose data does not change often, such as /boot.
The added overhead of the ext3 journal offers no benefit on these
filesystems.
Why would you place /var at the beginning of the disk? - Answer✔️✔️-The
/var filesystem contains files that are modified frequently. The beginning
of the disk is near the outer edge and data can usually be accessed faster
from this location.
How can you keep other users from using write to communicate with you?
Why would you want to? - Answer✔️✔️-Give the command mesg n to keep
ordinary users from writing to your termi- nal. You can take this action
when you do not want to be disturbed or when you are viewing something
on your screen that you do not want overwritten.
What happens when you use diff to compare two binary files that are not
identical? (You can use gzip to create the binary files.) Explain why the diff
output for binary files is different from the diff output for ASCII files. -
Answer✔️✔️-Give the command mesg n to keep ordinary users from writing
to your terminal. You can take this action when you do not want to be
disturbed or when you are viewing something on your screen that you do
not want overwritten.
What is an inode? What happens to the inode when you move a file within
a filesystem? - Answer✔️✔️-An inode is the control structure for a file. If the
two filenames have the same inode number, they share the same control
structure and are links to the same file.
Assume permissions on a file allow you to write to the file but not to delete
it.
a. Give a command to empty the file without invoking an editor.
