Question

A laptop computer communicates with a router wirelessly, by means of radio signals. The router is connected by cable directly to the Internet. The laptop is 8.0 m from the router, and is downloading text and images from the Internet at an average rate of 264 Mbps, or 264 megabits per second. (A bit, or binary digit, is the smallest unit of digital information.) On average, how many bits are downloaded to the laptop in the time it takes the wireless signal to travel from the router to the laptop?

Explanation / Answer

here ,

time taken by signal to travel , t = distance/speed

t = 8/3 *10^8

t = 2.67 *10^-8 s

Now ,

number of bits = 264 *(1024)^2 * 2.67 *10^-8

number of bits = 7.38 bits

the bits downloaded in laptop in this time is 7.38
