− | At the time this comic was written, most residential buildings in North America were wired for {{w|Analog device|analog devices}} using the old {{w|plain old telephone service|landline telephone service}}s, although thanks to the growth of {{w|internet telephone}} and wireless telephone technologies, including {{w|cordless telephone|cordless}} and {{w|mobile phone|mobile}} phones, this in-house wiring was increasingly redundant. See also {{w|Wireless telephone#Use of mobile phones|Use of mobile phones}}.
| + | The comic depicts how ideally you could convert phone lines to ethernet lines by simply faxing an ethernet cable to someone else. |
− | | |
− | At the time, people who took their internet access seriously would have preferred that at least some of the phone wiring and phone jacks in their residences were {{w|Ethernet}} ({{w|Cat-5}} or {{w|Cat-6}}) wiring and ({{w|Modular_connector#8P8C|RJ45}}) jacks for providing wired internet access throughout their home, or in this case, to their neighbor's home, so that they wouldn't have to resort to {{w|Wi-Fi}}, which was then slower and less reliable than a wired connection.

− | | |
− | The title text suggests that it shows a fanciful way of converting analog phone lines to {{w|digital}} ethernet lines by simply faxing an ethernet cable, since a fax machine is a tool for {{w|digitizing|converting}} analog content into digital.
| |
− | | |
− | Since the faxing of the ethernet cable is apparently successful, the comic is not really about the conversion, but is instead a subtle {{w|computer network}} joke about {{w|Tunneling protocol|tunneling}}, whereby you can embed one kind of network access protocol within a very different protocol. Herein lies the humor: [[Cueball]] and [[Megan]] are apparently under the impression that they can achieve a faster connection by tunneling a high-speed protocol (ethernet) through a slower (landline telephone service) one. Generally speaking, this is not true. The only exception is when embedding a compressed data stream within a non-compressed standard. The performance boosts, however, are typically modest for {{w|lossless compression}}, and not the orders of magnitude difference our novices apparently hope for.

− | The title text, which is a reference to foonetic user relsqui, was changed to correct their name to "Finn" after they came out as agender. (This comic was presumably inspired by [http://www.xkcdb.com/2001 this conversation] they had over IRC.)
