Configuration for Privilege Levels
Cisco switches (and other devices) use privilege levels to provide password security for various levels of switch operation. By default, Cisco IOS software operates in its two modes (privilege levels) of password security. user EXEC (level 1) and privileged EXEC (level 15).
- User EXEC mode (privilege level 1)
- Privileged EXEC mode (privilege level 15)
With a privilege level, you can bind a command or multiple commands.
For Example:
In a firm, there are 2 network engineers, and the organization does not want the same work for both engineers, so with privilege level one engineer namely, ABC is allotted the work to configure AAA, Firewall, and Net Flow. So, whenever the engineer will log in to their profile they can only do the work that is allotted to them. The second engineer is allotted the work of Routing and Interfaces. So, with privilege levels, the work allotted to a particular engineer will be allotted to them only and the other engineer cannot interfere in the other engineer’s work.
Advantages:
- Superior performance for querying related data, big or small.
- It has better problem-solving skills that are both practical and impractical for relational queries.
- It updates the data in real time and supports queries simultaneously.
Disadvantages:
- It does not provide the desired flexibility.
- Privilege levels cannot specify access control to interfaces, ports, or slots.

A group of computers that are connected to each other for the purpose of sharing their resources is called a computer network. The first computer network is ARPANET which stands for Advanced Research Projects Agency Network.
