If you are looking to use one existing Ethernet cable to support two
different computers then it is possible, provided the devices involved,
router or switch, computer Ethernet ports, are designed for 10 or 100MBs
speed. 10 to 100Mbs only utilize 4 of the 8 wires in the cat5/6 cable
per computer leaving the other 4 wires for a second computer or even
phone line(s).
The newer 1000Mbs systems use all 8 wires for just one computer and as
such can not be split without the use of a Ethernet bridge or router and
you can not mix an old style analog phone and computer on the same cable
with one of them.
There used to be all in one splitters pre-wired wall plates but I seem
to remember they cost about the same as a modern 4 port Ethernet bridge.
Here is a link to a video showing how to use the little pre-made
Ethernet splitters that plug into the wall jack and allow two computers
to run on one cable, but they have to be used in pairs, one at each end
of the cable being split.

The above is one long URL so if it comes in two parts at your end you
have to enter all of it into the browser to use it.
You could be use the "splitters" to run one computer and up to two phone
lines on the same cable provided the already mentioned speed
restrictions are kept in mind but that would most likely require you to
make special adapter cables for more than one phone line.
You could use one of the above modular splitters at the switch/router
end and hand wire a double Ethernet jack set at the end with the two
computers if you want provided you understand which wires to route to
each wall jack.
