What is a proc map?

Can anybody tell me what is a proc map? How it is useful and how to check it?

Thanks in advance.

Here is one of the proc maps, can someone explain what does it signify?

enter code here
-bash-3.2# cat /proc/2064/maps
 00008000-00009000 r-xp 00000000 00:0e 33036189   /tmp/efence/dev.out

The file /proc/[pid]/maps is a way to see the memory regions mapped by a process. Read about /proc for more info on other useful stuff you can find there.
