a Wireless Cable/DSL Router, which is a Combo unit that includes Router to share the Internet, Switch for Wired Network and A/P for Wireless clients (plus more goodies).
In its simplist form, a wireless access point is a bridge between wired Ethernet and wireless Ethernet (802.11b). An access point is not needed for two wireless computers to talk to each other, but it is vital for free communication between wired and wireless networks.
