Communication Path Hardware

Twisted Pair

Coaxial Cable

Fibre Optics

Wireless

If everyone in the world was connected to everyone else, the total number of connections would be "Population x Population - 1"

If people are connected to interconnected routers, then the total number of connections uses a logarithmic equation and hence much lower.

 =Communication Path Hardware=
-Phone cable. Vulnerable to noise, which disrupts information packets (changing magnetic fields induce current in the unprotected wire). Maximum speed is low because higher speeds cause greater noise.

-Coaxial cable. Less vulnerable to noise because the outer conductor shields the inner conductor. Reduced signal-to-noise ratio leads to higher maximum communication speed.
