Calculate the minimum time required

Hi,

You can find this material helpful.

 

Formula to calculate time = total number of bits to be downloaded/data rate in bps = total number of bytes x8/data rate in bps.

 

a. V. 32

 

Here

 

Total data = 2,000,000 bits

 

Data rate = 9.6 kbps = 9600 bps

 

Hence

 

Time = (2,000,000 × 8) /9600 = 1668 s

 

b. V. 32bis

 

Total data = 2,000,000 bits

 

Data rate = 14.4 kbps = 14400 bps

 

Time = (2,000,000 × 8) / 14400= 1112 s

 

c. V. 90

 

Total data = 2,000,000 bits

 

Data rate = 56 kbps = 56000 bps

 

Time = (2,000,000 × 8) / 56000 = 286 s

 

d. Cable Modem

 

We can calculate time based on the assumption of 10 Mbps data rate which is usually used:

 

Total data = 2,000,000 bits

 

Data rate = 10 Mbps = 1000 kbps = 10,000,000 bps

 

Time = (2,000,000 × 8) / 10,000,000 = 1.6 s.
