All about networking

Today we talked a lot about networking so I have postd all my notes over here.

802.11g is fater than 802.11b

b has a shorter range but is good if you don't want anybody to steal your wireless signals.
g is faster and has more range and is good if you want better info.

Problem with routers is that anybody ca view information that is sent even though it is encrypted. The good thing is that a router is a good firewall because hackers cant clearly reach our computer because the connection is though the router.
