Astrix (*) is used to multiply
Example: 5*5 (the answer would come out as 25)
If you’re using Excel, do it in the formula bar of course.
Is this for a test, because someone else asked that like 5 seconds ago.
Answer:
A. file locking.
Explanation:
File locking in computer technology is a data management mechanism used by software developers to completely restrict access of other users to a software program or computer file by granting permissions to only one user who can delete, modify or edit the application program at any point in time. This simply means that in the software development life cycle (SDLC), file locking is used to avoid interceding update on a particular software by restriction of other users while it's being modified by another user.
For instance, if two users (Gina and Mike) open the same software program, Gina then proceed to modify and save the changes. If Mike also modifies the software program and saves it, this would overwrite Gina's update. Hence, in order to prevent this type of conflict in software development, it is highly recommended that a file locking mechanism is adopted.
<em>This ultimately implies that when Gina make changes to a file, no one else is allowed to access the file because a file locking mechanism is being used by Gina's company as a version control process. </em>
