<span>In the process of 5B/6B encoding, it is possible to have the following two kinds of data sequences: 1. 25=32 data sequences 2. 26=64 data sequences Therefore, this can left us with some unused code sequences that are 32 in number (=26 – 25). On the other hand, in the encoding process of 3B/4B, it is possible to another set of data sequences as follows: 1. 23=8 data sequences 2. 24=16 data sequences This type of encoding also leaves us with some unused code sequences that are 8 in number (=23-24). 2. </span>
Answer:
b. This would set the group ownership of file1 to root.
Explanation:
Linux allows user to have his own files and regulate the ability of other users to access them. The <em>chown</em> command allows you to use the appropriate utility to change the owner of a file or directory.
The basic command syntax is as follows:
# chown [options] <owner name: owner group name> <file or directory name>
For example, if you want to give a user <em>root</em> opportunity to use the <em>file1.txt</em> file as he wishes, you can use the following command:
# chown root file1.txt
In addition to changing the owner of a file, the group of its owners or both can be changed at the same time. Use a colon to separate the username and user group name (without the space character):
# chown user2:group2 file1.txt
As a result, the user with the name <em>user2</em> will become the owner of the <em>file1.txt</em> and its group will become <em>group2</em>.
In your case omitting username
# chown :root file1.txt
will change owner group only.
Answer:
VM escape attack
Explanation:
<em>In a VM escape attack, the attacker exploits hypervisor vulnerabilities to gain control over resources reserved for other guest operating systems. Services operating on the guest may be exposed to the other attacks, but such attacks can only access data allotted to the same guest. In the event of a buffer overflow or directory traversal or the client in the case of cross-site scripting.</em>

Answer:
Data is a piece of an Information or a raw form of information while an Information is a processed Data.
Explanation:
An example of Data would be Alphabets of someone's name while the name would be an example of an Information.
On it's own, data makes no sense and needs to be processed to become Information which makes sense.
