ACL help

in CCNA & CCENT
I have question on a practice exam. Creating a standard access list to allow telnet from a specific computer....... that right there is throwing me off. If are only deny/permitting telnet traffic, how can you specify with a standard ACL. The example states that after you create the named list, Permit host x.x.x.x . Again that's stopping all traffic. Nothing is specifying telnet traffic. please help. thanks in advance

An extended ACL is more granular is specifying source/target/traffic types.
On Router1, issue the following commands to configure a standard ACL named Router1_ADMIN:
Router1#configure terminal Router1(config)#ip access-list standard Router1_ADMIN
On Router1, issue the following command to add an ACL statement that allows Telnet traffic from PC3 (10.10.0.3):
Router1(config-std-nacl)#permit host 10.10.0.3
