"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]

Implemented ~Kvng (talk) 19:22, 3 April 2020 (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]
