I have a very basic question on Computer Communication / Networking.
1. If I have two brand new computers with the standard NICs installed. What protocols would be used if i connect them directly using a cross-over cable but without assigning any static/dynamic IP address. Will their be any connection between them without an IP address assignment?
2. What protocols would be used if I connect the two using a Hub or a switch but no IP addresses assigned?
3. If on a LAN hosting a DHCP server, what protocols would be triggered BEFORE acquiring a dynamic IP from the DHCP server? and what protocols after the DHCP server and at which OSI layer they work?
