Two main types of data transmission media?

Here, we have two types of transmission media:

1. Guided media transmission


2.unguided media transmission


in guided media,there are wires or cables, whereas in unguided media,different-different waves are used.


1. Guided media transmission
a.) co-axial cables
b.) twisted pair cables
c.) optical fiber cables


2.) unguided media transmission
a.) infrared rays transmission
b.) radio transmission
c.) microwave transmission
d.) satellite communication transmission
