The database system allows the creation of a single depository of information, which is updated periodically and which can be used simultaneously by many users, since this type of system allows the effective sharing of all data stored in its depository . In addition, this is a secure system and is very difficult to break into. This is because of the efficiency of the software used to maintain it. However, the use of these softwares can be a little complicated for users, in addition to requiring a high economic cost to obtain them.
The traditional file system, in turn, each user must obtain their own file related to the application they want to run. This may seem dull in comparison to the database, but it is advantageous as it does not require any spending on software, as it is simple and there are several cheap and efficient tools and editors on the market. However, this system is not so safe, it can cause isolation of data and even data inconsistency, which disrupts the entire system.
Answer:
long power(int i)
{

The passwd is a folder in the Linux OS that holds the login details of all users in the system network. The 'awk' is one of the commands used to get information from a file in a folder.
