a. Both devices are using the same shared and open protocols
b. A single direct connection is established between any two devices connected to the Internet
c. The data of the image is routed through a sequence of directly connected devices before arriving at its destination.
d. Both devices are directly connected to at least one part of the Internet

Respuesta :

Answer:b

Explanation:

MrRoyal

In other to send files from one device to another, the devices must be connected in one way or the other.

(b) A single direct connection between the devices is not necessary.

Of the given options, option B is not a necessary requirement for Jesse to transfer images to his friend.

The reason is that:

When a single direct connection is used to connect devices, it means that:

  • The devices are at a close proximity (e.g. devices in the same room)
  • The devices need a cable for their connection to be successful.

From the question, we understand that his friend is in another country.

This means that it is practically impossible for their devices to be at a close proximity and by extension they cannot use a cable to connect their devices (i.e. phones).

However, other options are true because:

  • Their connection must be universal i.e. (a) shared and open protocol
  • They must be connected through the internet i.e. (c) and (d)

Hence, option (b) is not necessary.
