Answer:
C I believe but I'm not a hundred percent sure
Answer:
321Go
Explanation:
The identifiers in C, C++, C#, Java and other programming languages are a combination of letters, numbers and the underscore symbol. The laters versions of C and C++ allows you to use almost all Unicode characters. In Java, you can use also the dollar sign.
From that you have to be careful to follow these rules:
-Don't use keywords.
-Don't include white spaces.
-Don't use operators.
-Don't repeat identifiers.
-Don't start your identifier with a number.
-Don't use two consecutive underscores.
So app_234, happyTimesAhead, and cis22B are follo wing these rules but 321Go starts with a number.
Answer:


Explanation:
Binary and hexadecimal values have the following pair equivalences.
















We convert from binary to hexadecimal selecting groups of 4 binary from the binary code, from the least significant bits(at the right) to the most significant bits(at the left). The conversion is an hexadecimal "string" from the last group you converted to the first. So:
(a) %100011100101



So

(b) %1011001111




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.
