:roll: :roll: :roll: :roll:
i am still thinkin about datalink layer and itz switchz
i heard about it dat communicatin iz posible by MAC although if no ip existz in LAN...
but in Lan if ip iz removed ..there wll no communication b/w or among devicez

then why v saying only MAC addss can do all IN LAN if no ip addrss there..???
plz i still under confuzion to make any concept about datalink layer or mac and swichez for ip??
i thinking any1 wll give some simple discribshan and example to clear my concept about it...? :roll: :roll: :roll: :oops:

If someone is saying you only need Mac addresses they are mostlikely referring to some old tech that doesn't really get used anymore because networks are to big for just mac addresses to be in use. I'm pretty sure I covered all of this in my last segment about why mac addresses and IP addresses are both important.
