I know this is going to seem like a stupid question but...

i'm having trouble figuring out cisco's way of denoting memory sizes.
On my switch is says it has 21295K bytes of memory.
cisco WS-C2950-24 (RC32300) processor (revision R0) with 21295K bytes of memory
Now are they saying 21295 thousand bytes or are they saying K as in KB? And I want to confirm this is the amount of RAM in the system...
Then it says:
32K bytes of flash-simulated non-volatile configuration memory.Why is the flash "simulated" and whats its relationship to NVRAM in this case?

It's K bytes, and don't worry too much about that for a switch as it's the routers where you need to pay more attention on how much RAM and FLASH they have installed.2015 goals - ccna voice / vmware vcp. -

2950s don't have room for more flash.
Upgrading Software Images on Catalyst 2950 and 2955 Series Switches Using the Command Line Interface - Cisco Systems
DRAM Memory
All 2950 and 2955 series switches can have up to 32 MB of SDRAM. However, there are no minimum DRAM requirements to consider before you upgrade software on these switches.
FLASH Memory
All 2950 series switches have 8 MB of internal Flash memory. All 2955 series switches can have up to 16 MB of Flash memory. You cannot upgrade the Flash memory.2015 goals - ccna voice / vmware vcp.
