Answer:
Explanation:
If the HDD is spinning, this means that the power cable is correctly connected and that the drive is receiving power and powering on. However, this does not mean that the HDD is functioning correctly and reading the information. Therefore, the next logical step would be to check the SATA cable that connects the drive to the motherboard. The cable may be broken or maybe the SATA slot on the motherboard. Switch out the cables and plug it into another slot. If this does not work, then it may be that the HDD is broken. Multiple Beeps can also mean that the RAM or CPU is not plugged in correctly or broken.
Answer:
B. root
Explanation:
Every user in Linux is assigned a folder from which they can store their files. The interpreter allows you to abbreviate your route with the “~” symbol. The ls command without any additional data shows the files in the current directory, but if after the name of the command a path is written, it shows the files in that path. Therefore, the ls ~ command shows the files in the user's folder.
In addition to the folders and files created by the user or programs, every Linux folder has two subfolders defined by default:
“..”: It is the top level folder in the file hierarchy that contains it. This subfolder is also present in the root of the filesystem (the folder with absolute path “/”), but points to itself.
“.”: It is the folder itself that appears as if it were also a subfolder. It can be considered as a "self-reference" or pointer to itself.
These folders are normal folders in the system for all purposes; that is, they can be used on routes. For example, the path /dirA/dirB/dirC/../fichero2.txt refers to the file that is stored in the dirB folder, since from dirC, the folder .. points to its predecessor, dirB. The following figure shows the interpretation of this route as well as the equivalent of the “..” and “.” Folders.
