Answer:

D. infrared.

Explanation:

Wireless technology for communication uses electromagnetic wave to transmit signals between location. It eliminates the need of cables for connecting network devices.

In previous wireless technology implementation, Infrared rays were used (in tv remotes), which needed to be in the line of sight to its destination. Although it was fast, it has many limitations for a long-haul transmission like its short transmission range, easily blocked by objects and its uni-directional properties.

Alex Ar [27]

Answer:

Written in Python:

dollars = int(input("Amount: "))

numFive = int(dollars/5)

numOnes = dollars%5

print(str(dollars)+" yields "+str(numFive)+" fives and "+str(numOnes)+" ones.")

Explanation:

This line prompts user for input

dollars = int(input("Amount: "))

This line calculates the number of 5 that can be gotten from the input. This is done using integer division

numFive = int(dollars/5)

This line gets the remaining ones. This is done by using the modulo sign to get the remainder when input is divided by 5

numOnes = dollars%5

This line prints the required output

print(str(dollars)+" yields "+str(numFive)+" fives and "+str(numOnes)+" ones.")
