in old times Ethernet used to be known as RJ45 cable. is it not changed now ? I mean now if I have 2 routers on a distance of 500 meters , we use fiber right ? so fiber cable also supports enternet ? how long it can go then or we need some repeater sort of thing ?
- I know that we also have PoS but what it is ? is that only for wan ? what all other technologies exist like as PoS in today’s networks ?
