Major disadvantage of asynchronous transmission is that the transmission lines is idle during the time intervals between transmitting characters.
one disadvantage for wave power is that if a body of water isn't moving the machine can't produce electricity. another disadvantage for wave power is the machine can disrupt ocean life if it is near it's nesting ground a last disadvantage for wave power is it's very expensive
electromagnetic wave
It is a type of mechanical wave known as a seismic wave.
easy for transmission of data data can be cracking can be dertermine
transmission
Radio waves are a type of electromagnetic wave.
The next type of seismic wave to arrive after the P-wave is the S-wave.
Every type of sound wave produced is a longitudinal wave.
a seismic wave
An electromagnetic wave is a radiant wave.
