Switchport mode access means this is an access port and not a trunk port for instance.
Switchport voice vlan means any voice device (determined by CDP) you connect will be put in vlan 999.
no mdix auto means you will need to connect to this port with a straight through cable. if you turn it on, it means you can use a cross or a straight through and the port will adjust itself with whatever is needed.

Portfast will make the the connection come back on line faster after there has been a connection loss on 1 of the redundant uplinks.
The "switchport host" macro available in most of the Catalyst IOS based CLI is a very useful tool to optimize the port for a host connection, the switchport host command sets switch port mode to access, enables spanning tree Port Fast, and disables channel grouping. Only an end station can accept this configuration, of course.
