Ask the top command when swap is not set in the embedded Linux environment

Source: Internet
Author: User
For more information, see Linux general technology-Linux programming and kernel. In a general Linux environment, if swap partition is set, the third and fourth rows in the result of using the top command are generally like:

Mem: 255620 k total, 250792 k used, 4828 k free, 77352 k buffers
Swap: 524280 k total, 872 k used, 523408 k free, 43260 k cached
Among them, cached refers to the total number of buffer swap areas. The content in the memory is swapped out to the swap area and then into the memory, but the used swap area is not covered yet,
This value indicates the size of the SWAp zone where the content already exists. When the corresponding memory is swapped out again, you do not have to write data to the swap zone.

However, the swap partition is not set in the embedded Linux environment I am currently developing. However, in command line debugging mode, the result of executing the top Command is as follows:

Mem: 17012 K used, 75504 K free, 0 K shrd, 348 K buff, 10736 K cached

I would like to ask you where the 10736 K cached cache space is ?, Thank you.
