It's possible but doesnt' worth it, just buy a lan cable.
You can't using telephone cables. Telephone cables use 4 wires, but none of the wires are twisted, so there will be problems with crosstalk. Also, telephone cables use an incorrect connector (RJ-11) for a NIC card in a PC, which needs RJ-45 connectors.
You would connect them with ethernet cables and 1 or more switches. If you require more than 1 switch, you need to connect the two switches with an ethernet cable too.
1) connect the ip phone to the ethernet LAN using an rj45 connector 2) establish an internet connection then use an analog telephone adapter.
Connect using Wi-fi instead.
You can connect other computer to your computer throught different ways.Other computer can be connected to your using LAN cable or usb cables. when other computer is connected to your you need to setup a group in my networks or network option.
Either use a crossover cable or connect them using a hub, switch, or router.
Yes, it can. You can use for printers with own NIC, or you can connect your printer to a printer server, or you can connect you printer to your router (not all routers support it), or you can connect the printer to your computer which is connected to the network and share the printer.

Local Area Network Cable usually associate with a bus topology network. In a Bus topology network simple LAN cables are used with LAN Hubs ( i.e. having a collection of LAN ports ) which in turn connect many systems with the server systems. LAN cables are available in various length ranging from 1meter onwards.
I'm pretty sure LAN's are a group of computers connected to each other through routers/modems or ethernet cables. The internet it similar to LAN's but instead of connecting to other computers close by, it connects to computers all around the world.
Check out for availability of two unused PCI slots on Motherboard. You can connect PCI based LAN cards. IF possibility for PCI based LAN cards are dimmer then one can go for other modes such as USB based LAN cards.
That is a LAN with cables as opposed to wireless LAN without cables. Network cables now mostly used for a wired LAN are UTP (unshielded twisted pair) CAT5E, although STP (shielded twisted pair) and CAT6 or CAT7 specifications are also used. Before COAX cables were used.
