i have a host that uses the Ethernet card within a lan

My questions are

1 . How does the ethernet card know that it must resend a packet ? if the packet hasnt reached its destination address

2. Can the host send directly a packet to another host that does not belong to the same physical network

thanks in adavance for your help

1. It doesn't. That's up to a high level protocol like TCP.

2. It can't. That's what a gateway/router is for.
