An image is 1024*800 pixels with 3 bytes/pixel Assume the image is uncompressed. How long does it take to transmit it over a 10 Mbps Ethernet ?
A. | 196.6 seconds |
B. | 19.66 seconds |
C. | 1.966 seconds |
D. | 0.1966 seconds |
Option: C Explanation :
Size of the Image = 1024 x 800 x 3 bytes
= 2457600 bytes
= 19660800 bits
The time it takes to transfer the image over 10 Mbps Ethernet is
10,000,000 bits = 1 second
19660800 bits = 1.966 seconds
