WHICH LAYER ENSURES THAT PACKETS ARE DELIVERED ERROR FREE?

1 reply

by erikdr

The 4th is the first layer where this can be accomplished. In the TCP/IP stack here you have the choice between TCP (errorfree and slower) and UDP (broadcast, faster, but sometimes errors). However higher layers also can have errorchecking on their 'packets'. Layer 1-2 do not really contain packets and layer 3 (IP) leaves the checking to the higher level...
