Linux Chapter 2
2. What is an installer?
An installer is an application that installs a software or an operating system to a machine.
3. Would you set up a GUI on a server system? Why or why not?
I would not set up a GUI on a server system. A GUI is good for a desktop system. Even though a GUI is user friendly, I would use a textual interface because it allows the system to dedicate more resources to carrying out the job it is set up to do. Also not running a GUI can improve system security.
5. What is free space on a hard disk? What is a filesystem?
Free space on a hard drive is the area of a partitioned disk that is not occupied by partitions. A filesystem is a data structure that needs to be written to the partition. This structure holds inodes that map locations on a disk that store files to the names of the files.
7. Give two reasons why RAID cannot replace backups.
The two reasons why RAID cannot replace backups is because its purpose is to improve fault tolerance and improve performance. RAID is useless if there is any catastrophic failure to the system. Also RAID does not replace a file if it is mistakenly deleted by the user.
9. What is SHA1? How does it work to ensure that an ISO image file you download is correct?
When you download the SHA1SUMS file, SHA1 is included. This file is useful in determining of the ISO image file that you downloaded was correct. When you use the utility, sha1sum generates a number based on the file. If the number matches the corresponding number in the SHA1SUMS file, the download is correct.
