When preparing for your Cisco CCNA or just learning the IOS, there are a number of terms that you need to know. Here are 5 of them:
1. Administratively Down – One possible interface on a Cisco router.
2. Assignable IP address – An IP address that can be assigned to an interface excluding reserved IP addresses in a subnet.
3. Bootstrap – The program that a computing device loads, using hardware, to initialize enough software to look for and load the fully functional OS.
4. Cisco IOS – The operating system that runs in a Cisco router.
5. Cisco IOS image – A single file that contains a complete copy of the IOS.
