private networks connected to the Internet.It regulates
traffic of the network of different trust levels.

are applied to port numbers or network daemon names that are
available on a host, each with a list of hosts and/or
networks permitted to use the service. Both individual
servers as well as routers can have network ACLs.

Answer / pravin

Firewall-is a mechanism.
ACL is set of rule.

And we can say mechanism is reversible in nature while rule are irreversible.Means firewall check both side of data when we want to send or we receive while in ACL rules are applied only on instructed interface means on inside or out side. 

Answer / devroy

An ACL is a basic level of stateless packet filtering. If
that meets your (low) security requirements, then that's
fine.

A firewall generally includes stateful packet inspection.
This will provide a higher level of security than an ACL.

That said, you need to look at the specific
implementations, as what one vendor calls an ACL another
may call a firewall.
