Answer:
The command to create a compressed archive (archive1.tar.gz) is
Explanation:
The explanation for the above command is
The general command to create a compressed archive is
tar -czvf name-of-archive.tar.gz /path/to/directory-or-files
Here, the terms are as follows:
-c : Creates an archive
-z : Compress the archive with gzip.
-v : This is known as verbose. This is an optional command and it displays the progress on terminal command. Without this the progress is not displayed on terminal command.
-f : Allows to specify the file name of the archive.
Here, if we want to archive multiple files, we provide the command the names of multiple files or directories of the files also can be used.
So, the command
creates a compressed archive - archive1.tar.gz of files test1, test2 and test3.
Answer: An example of such a scenario would be when the user name and password meant to allow access to a customers bank account statement is cracked by unauthorized people this causing alteration (in the form of data diddling attacks) in the data contained in the statement. This is a compromise in integrity.
Explanation:
Confidentiality entails securing things people want to remain secret. An account statement of a bank customer is a confidential document which is to be kept secret. A password allows access to it.
Integrity implies receiving a sent data/information as accurately as it came from a sender. A data diddling attack alter integrity because the original information is altered by an unauthorized person.
Answer:
class Main {
static void printPowers(int howMany, int nrRows) {
for(int n=1; n<=nrRows; n++) {
for(int power = 1; power<=howMany; power++) {
System.out.printf("%d ", (int) Math.pow(n, power));
}
System.out.println();
}
}
public static void main(String[] args) {
printPowers(3, 5);
}
}
class Main {
static void printPowers(int howMany, int nrRows) {
int n = 1;
do {
int power = 1;
do {
System.out.printf("%d ", (int) Math.pow(n, power));
power++;
} while (power <= howMany);
System.out.println();
n++;
} while (n <= nrRows);
}
public static void main(String[] args) {
printPowers(3, 5);
}
}
Explanation:
The for loop gives the cleanest, shortest code.
