What is the data transmission time, assuming no errors or overhead, to send a 2 GByte file over a link with a 2 Gbps line rate? Remember that the 'G' in GByte and Gbps have slightly different meanings. Round your answer to the nearest 0.1 second and show your work.

The data transmission time will be 8 seconds (8.0s)

Explanation:

Using the formular:

T = A/S

T=Time = ?

Amount of Data = A = 2GByte

Speed = S = 2Gbps

The units of A and S are different

A is expressed in Bytes (B)

S is expressed in bits (b)

But:

1 Byte (B) = 8 bits (b)

T = A/S = 2GB/2Gb

since 1 Byte = 8 bits

T = 2 * G * (B = 8bits) / 2 * G * b

T = 2 * G * 8b / 2 * G * b

T = 2 * G * 8 * b / 2 * G * b

The common terms (2, G, b) cancel out

T = 8 seconds
