When you send a text message from your phone, the letters and words are first converted into what form for digital transmission?

A set of analog electrical signals

The use of binary code makes a digital signal 'robust.' What does this characteristic primarily help to ensure?

That the information can be read by a wide variety of different devices from competing manufacturers around the world.

That the message arrives at its destination with high fidelity and minimal error.

That the signal can be encrypted for security purposes during transmission.

That the transmission uses the least amount of electrical energy possible.

It requires less power to transmit.

It uses only two distinct states.

It can carry more types of data.

It makes the signal much louder, so it can be easily heard over any background noise.

It converts the message into simple 'on/off' pulses that are easy to distinguish from random noise.

It sends the message multiple times through different pathways to ensure at least one copy arrives intact.

It translates the message into a universal computer language that all devices can understand instantly.
