Consider a point to point link 50 km in length. At what speed would propagation delay (at a speed 2 x 108 meters/second) equal transmit delay for 100 byte packets.

The bandwidth is 3200 Kbps

Explanation:

Given:

The length of the point to point link = 50 km = 50×10³ = 50000 m

Speed of transmission = 2 × 10⁸ m/s

Therefore the propagation delay is the ratio of the length of the link to speed of transmission

Therefore,  

Therefore the propagation delay in 25 ms

100 byte = (100 × 8) bits

Transmission delay =

If propagation delay is equal to transmission delay;

x = 3200 Kbps

when the first user logs into windows 10 or windows server and identifies their region, windows sets the time zone. the user can change the time zone at any time.

windows updates the time zones in the registry when time zones are available and updates are downloaded.

to get the most current list of time zones, use tzutil from windows:
