In which memory location is the routing table of a router maintained?ROMNVRAMRAMflash

Sure, let's break down the question step by step to determine where the routing table of a router is maintained.

1. Understanding the Routing Table:

   • A routing table is a data table stored in a router or a networked computer that lists the routes to particular network destinations. It contains information about the topology of the network immediately around it.

2. Memory Types in a Router:

   • ROM (Read-Only Memory): This is non-volatile memory used to store the router's firmware and bootstrap instructions. It is not used for dynamic data like routing tables.
   • NVRAM (Non-Volatile Random-Access Memory): This is non-volatile memory used to store the router's startup configuration file. It retains data even when the router is powered off.
   • RAM (Random-Access Memory): This is volatile memory used to store the router's running configuration and operational data, including the routing table. It loses its data when the router is powered off.
   • Flash Memory: This is non-volatile memory used to store the router's IOS (Internetwork Operating System) and other system files. It can also store backup configurations but is not typically used for the routing table.

3. Determining the Correct Memory Location:

   • The routing table is a dynamic data structure that needs to be updated frequently as the network topology changes. Therefore, it needs to be stored in a type of memory that allows for quick read and write operations.
   • Given the characteristics of the different types of memory, RAM is the most suitable for storing the routing table because it allows for fast access and updates.

Conclusion: The routing table of a router is maintained in RAM.
