Overview
Preparing for the CCNA exam can be challenging, especially when it comes to understanding the internal components of a Cisco router. This guide will help you distinguish between RAM, ROM, NVRAM, and Flash Memory, ensuring you're well-prepared.
Key Components
ROM (Read-Only Memory):
- Stores the router's bootstrap startup program, operating system software, and power-on diagnostic tests (POST).
Flash Memory:
- Contains the Cisco Internetwork Operating System (IOS) images.
- It is erasable, reprogrammable, and retains content even after power-down or reload.
RAM (Random-Access Memory):
- Holds operational data such as routing tables and the running configuration file.
- Contents are lost when the router is turned off or reloaded.
NVRAM (Non-Volatile RAM):
- Stores the startup configuration file and retains its contents after power-down or reload.
- If empty upon reload, the router will prompt entry into setup mode.
