Answer:
The correct answer is C. Sometimes.
Explanation:
A database index is a structure that aims to speed up selections and selective operations on a database. An index reduces the number of comparisons required to find one or more database records. This avoids having to perform a so-called full table scan, whereby all records in the table have to be run through sequentially.
Therefore, if the search does not focus correctly on the necessary data, this search will not always determine the index of the goal. Therefore, the user must correctly handle the search keywords to collaborate with the system.
Answer:
A. While new media is dependent on whether users function in real-time or delayed mode, feedback is not as timely when communication is asynchronous.
Explanation:
Asynchronous communication can be defined as a data communication technique in which exchange of data between a sender and a recipient isn't in real time.
There's usually a time lag, meaning it doesn't require the recipient to respond immediately.
For example, responding to an email or text several hours later.
I believe the answer could be the first choice. I'm not quite sure, though
Answer:
public class num6 {
public static void main(String[] args) {
int n = 4;
for(int i = 1; i <= n; ++i) {
for(int j = 1; j <= i; ++j) {
System.out.print("* ");
}
System.out.println();
}
}
}
Explanation:
This solution is implemented in Java
Two for loops are required for this (an inner nd outer for loop).
The innner and outer for loops can be seen as implementing rows and columns (so on the first 'row' i=1, so a single star is printed, on the second row, i =2, two stars are printed and so on, all on seperate lines)
