minus-squarecredo@lemmy.worldlinkfedilinkarrow-up5·edit-21 day agoISO is an organization. OSI is a model. Edit: there are also definitely more than four “layers” (standard handoff points). Physical involves the media and transmission format (e.g. EMF, waveform, etc) data link involves multiplexing and addressing on the local segment Network involves beyond-segment addressing Transport involves standard endpoint communication methods (tcp/udp) Are you implying this is where everything ends? What about application level multiplexing (sockets)?
