Standard Access Control List
From Wikipedia, the free encyclopedia
Standard Access Control Lists (ACL) are Cisco IOS-based commands used to filter packets on Cisco routers based on the source IP Address of the packet. Extended Access Control Lists have the ability to filter packets based on source and destination IP addresses.

Numbers between 1 and 99, or any number between 1300 and 1999 can be used in a Standard ACL. The number used in this range doesn't affect how the ACL is processed or which ACL is more important to the router.
The difference between Named and Numbered ACL's is the name associated with the ACL and not the number. Names are easier to remember than a number.
