Data Transmission

ASYNCHRONOUS

$\begin{figure}\centerline{\epsfig{figure=/home/sri/courses/figs/eps/asyn.eps,width=3in}} \end{figure}$
- High Overhead (20%)
- Slower speeds
- Simpler circuitry $\rightarrow$ Lower cost
- Dial-up lines
SYNCHRONOUS

$\begin{figure}\centerline{\epsfig{figure=/home/sri/courses/figs/eps/syn.eps,width=3in}} \end{figure}$
- Low Overhead (much less than 20%)
- High speeds
- Complex circuitry $\rightarrow$ Higher cost
- Leased lines
