What is crawling and notification?

What is the difference between a process' private bytes, virtual bytes, and working set size?
Virtual bytes accounts for all memory of a process. Private bytes is a subset of virtual bytes that is not shared. Working set size is the amount of memory that is in physical memory (RAM).
500
On a DAC-enabled node, what is the DACP bit and how is it changed?
It controls whether databases can be mounted on that node. On startup, it is 0 and changes to 1 when either of these conditions occur: all nodes in the StartedMailboxServers list can be contacted, or the node communicates with another node that has a DACP bit of 1.

What is .NET garbage collection?
In a running .NET process, whenever memory is allocated or there's memory pressure, .NET garbage collection runs to clean up objects that have not been used/referenced in a while.
