Router memory/storage

In the following "show ver" output, what are 114688k and 16384K bytes of memory? RAM?

I know 191K bytes is the NVRAM amount that can hold the configuration file. However, what is the 31360K bytes of ATA CompactFlash?

Found this on the official documentation for show version:

Cisco platform (processor-type) processor (revision processor-revision-id) with free-DRAM-memory K/ packet-memory K bytes of memory.

Example—Separate DRAM and Packet Memory:

Cisco RSP4 (R5000) processor with 65536K/2072K bytes of memory

Example—Combined DRAM and Packet Memory:

Cisco 3660 (R527x) processor (revision 1.0) with 57344K/8192K bytes of memory.

That's the Flash. Flash is where a router stores the OS (IOS) image and in some cases the VLAN Database. 32 MB is rather small for an ISR Router. You can pick up a larger Compact Flash Card on eBay rather cheaply. I've read that generic (non Cisco Branded) CF cards might work, but I was unable to find any smaller than 4 or 8 GB in any store as they only really sell them for use in DSLR Cameras. So, I ended up buying a 256 MB Cisco Branded CF Card on eBay.

It appears you have 128 MB of DRAM and 32 MB of Flash Memory.

So basically it's the RAM amount. But what is Packet Memory? What's its function? Why is it listed separately?

Packet memory (used by incoming and outgoing packets).
