Zuk zeuk sortu dituzun fitxategiez gain, ordenagailuak baditu sistemak ongi funtzionatzeko behar dituen fitxategi asko. Sistema-fitxategi horiek oker aldatzen badira, eginbide batzuk hautsi egin daitezke, eta horregatik daude, hain zuzen, aldaketetatik babestuta. Azplikazio batzuk ere, sistemaren atal garrantzitsuak aldatzen dituztenez, babestuta daude.
The way that they are protected is by only allowing users with administrative privileges to change the files or use the applications. In day-to-day use, you will not need to change any system files or use these applications, so by default you do not have administrative privileges.
Sometimes you need to use these applications, so you may be able to temporarily get administrative privileges to allow you to make the changes. If an application needs administrative privileges, it will ask for your password. For example, if you want to install some new software, the software installer (package manager) will ask for your administrator password so it can add the new application to the system. Once it has finished, your administrative privileges will be taken away again.
Administrative privileges are associated with your user account.
Laburbilduz, administratzaile-pribilegioen bidez zure sistemaren atal garrantzitsuak aldatu ditzakezu beharrezkoa denean, baina nahi gabe egin dezazun eragozten da.
A user with administrative privileges is sometimes called a
superuser. This is simply because that user has more privileges
than normal users. You might see people discussing things like
Requiring users to have administrative privileges before important system changes are made is useful because it helps to prevent your system from being broken, intentionally or unintentionally.
If you had administrative privileges all of the time, you might accidentally change an important file, or run an application which changes something important by mistake. Only getting administrative privileges temporarily, when you need them, reduces the risk of these mistakes happening.
Only certain trusted users should be allowed to have administrative privileges. This prevents other users from messing with the computer and doing things like uninstalling applications that you need, installing applications that you don’t want, or changing important files. This is useful from a security standpoint.
