"Segments" redirection

edit

The "segments" link goes to a disambiguation page, the relevant link on which redirects to this page. 67.185.99.246 19:16, 29 January 2007 (UTC)Reply

That now goes to TCP segment instead. ~Kvng (talk) 19:22, 3 April 2020 (UTC)Reply

ISO7816 APDU

edit

APDU redirects here but the page says nothing about smart cards nor APDU. —Preceding unsigned comment added by 81.219.231.40 (talk) 00:01, 21 December 2007 (UTC)Reply

Smart card APDUs aren't the only types of APDUs in existence. Guy Harris (talk) 00:17, 21 December 2007 (UTC)Reply
APDU now redirects to Smart card application protocol data unit ~Kvng (talk) 19:22, 3 April 2020 (UTC)Reply

Physical layer: symbol instead of bit

edit

Shouldn't the PDU of the physical layer be the 'symbol' instead of the 'bit'? Most times bits are not transmitted individually if I'm not mistaken. Qorilla (talk) 11:30, 31 May 2010 (UTC)Reply

OSI model bias

edit

The TCP/IP model is under-represented here. With Internet Protocol as dominant as it is, doesn't pdu deserve to be shown in this light as well? Stephen Charles Thompson (talk) 20:02, 24 January 2012 (UTC)Reply

We now have OSI model and Internet protocol suite examples. ~Kvng (talk) 19:22, 3 April 2020 (UTC)Reply

OSI layer 1 PDU is bit / symbol vs PPDU

edit

Apparently the official definition of the OSI layer 1 PDU is the bit / symbol. Yet the diagram at the top of the article shows the layer 2 PDU encapsulated in a physical layer PDU.

Which is correct? Outside2017 (talk) 04:41, 27 September 2018 (UTC)Reply

Our TCP/IP Guide ref says the physical layer works on bits but doesn't identify that as a PDU. The diagram was made by a Wikipedia editor and does not indicate a source. ~Kvng (talk) 19:22, 3 April 2020 (UTC)Reply
