<title>நிர்வாக அனுமதிகள் எப்படி வேலை செய்கின்றன?</title>

<p><em>நீங்கள்</em> உருவாக்கும் கோப்புகளைப் போலவே, உங்கள் கணினி சரியாக வேலை செய்ய தேவையான பல கோப்புகள் கணினியில் உள்ளன. இந்த <em>கணினி கோப்புகள்</em> முறையின்றி மாற்றப்பட்டால், பல விஷயங்கள் செயலிழக்கலாம், ஆகவே முன்னிருப்பாகவே அவற்றுக்கு மாற்றம் செய்ய முடியாதபடி பாதுகாக்கப்பட்டிருக்கும். சில பயன்பாடுகளும் கணினியின் முக்கியப் பகுதிகளில் மாற்றம் செய்பவை, ஆகவே அவையும் பாதுகாக்கப்பட்டிருக்கும்.</p>

<p>The way that they are protected is by only allowing users with
35
<em>administrative privileges</em> to change the files or use the
36
applications. In day-to-day use, you won't need to change any system files or
37
use these applications, so by default you do not have administrative
40
<p>Sometimes you need to use these applications, so you may be able to
41
temporarily get administrative privileges to allow you to make the changes.
42
If an application needs administrative privileges, it will ask for your
43
password. For example, if you want to install some new software, the software
44
installer (package manager) will ask for your administrator password so it
45
can add the new application to the system. Once it has finished, your
46
administrative privileges will be taken away again.</p>
48
<p>Administrative privileges are associated with your user account.
49
<gui>Administrator</gui> users are allowed to have these privileges while
50
<gui>Standard</gui> users are not. Without administrative privileges you will
51
not be able to install software. Some user accounts (for example, the "root"
52
account) have permanent administrative privileges. You should not use
53
administrative privileges all of the time, because you might accidentally
54
change something you did not intend to (like delete a needed system file, for

<p>In summary, administrative privileges allow you to change important parts
58
of your system when needed, but prevent you from doing it accidentally.</p>

<title>"super user" என்றால் என்ன?</title>
62
<p>A user with administrative privileges is sometimes called a <em>super
63
user</em>. This is simply because that user has more privileges than normal
64
users. You might see people discussing things like <cmd>su</cmd> and
65
<cmd>sudo</cmd>; these are programs for temporarily giving you "super user"
66
(administrative) privileges.</p>

<title>Why are administrative privileges useful?</title>
72
<p>Requiring users to have administrative privileges before important system
73
changes are made is useful because it helps to prevent your system from being
74
broken, intentionally or unintentionally.</p>
76
<p>If you had administrative privileges all of the time, you might
77
accidentally change an important file, or run an application which changes
78
something important by mistake. Only getting administrative privileges
79
temporarily, when you need them, reduces the risk of these mistakes
82
<p>Only certain trusted users should be allowed to have administrative
83
privileges. This prevents other users from messing with the computer and
84
doing things like uninstalling applications that you need, installing
85
applications that you don't want, or changing important files. This is useful
86
from a security standpoint.</p>
