You don't - you'll need an Ethernet card for your computer. A regular voice/fax modem is different than a high-speed/network connection, so you need a different 'card' (with a socket that will match your cable). If you can't find a socket that your Ethernet cable fits, then you don't have an Ethernet card installed!
The Ethernet is part of the Internet The Ethernet is for local area networks or LANs and is shared over a span of one home or several apartments, while the Internet is used for world wide transmissions.
Not that I am aware of. Ethernet and POTS (Plain Old Telephone System) are two completely different methods of communication.
Ethernet addresses are 48 bits long - not 32 bits long like IP addresses. Different single network standards have different address lengths. Ethernet addresses are called MAC addresses for other reasons, Media Access Control.
An ethernet camera can be used for security purposes in much the same way as a regular security camera. The main difference is that images that the ethernet camera records can be viewed over the internet.
There are different types of gibabit Ethernet; the cabling can either be some kind of copper cable, usually UTP, or fiber optic.
There is no difference; Ethernet is Ethernet, regardless of where it is deployed.
Data link layer refers to things that happen within a single network; that's what a switch does. Only a router (or equivalent device, which I would still consider a "router") is able to connect different networks.The different networks may use the same technology (for example, Ethernet and Ethernet), or different technologies (for example, Ethernet and Wi-Fi); a switch is only able to connect parts of a single network that use the same technology (often this will be Ethernet).
