Assignment $2$

Not Graded

Exercise $1$:

A device is sending out data at the rate of $1000bps.$

a$.$ How long does it take to send out $10$ bits?

b$.$ How long does it take to send out a single character $(8$ bits$)?$

Exercise $2$:

How many bits can fit on a link with a $2ms$ delay if the bandwidth of the link is

a$.1$ Mbps$?$

h$.10$ Mbps$?$

Exercise $3$:

What is the total delay $($latency$)$ for a frame of size $5$ million bits that is being sent on a link with $10$ routers each having a queuing time of $2s$ and a processing time of $1s.$ The length of the link is $2000Km.$ The speed of light inside the link is $2{10}^8\frac{m}{s}.$ The link has a bandwidth of $5Mbps.$ Which component of the total delay is dominant? Which one is negligible?
