as you see into this picture , kr/keith bogart explaining application layer , presentation layer and session layer
he said that any application by itself is out of osi models (out of 7 layers), and there`s protocols into layer 7 that`s run with that application like ftp , dhcp , http , https , dns , snmp , ect
into first box in the picture ( http data get ine.com) there`s zeros and 1, that means layer 7 convert http protocol into 0&1 ? or what?
also into second green box (layer 6 application layer)that represent what? what is ascii? why he put another zeros and 1 that`s different than first black box?
