What is a key difference between protocols and standards?

Protocols are developed by recognised organisations, while standards are created by individual companies/groups.

Protocols are directly implemented on devices, while standards provide broad guidelines. (correct)

Protocols provide broad guidelines, while standards are implemented directly on devices.

Protocols are defined on how to implement, while standards are directly implemented on devices.

What does a protocol do at the sending computer?

Encrypts all data before transmission.

Delays the data transmission process.

Sends the data in its original form without any modification.

Breaks data into smaller packets, adds addressing information, and prepares data for transmission. (correct)

Why is it important for protocols to break data into smaller packets?

To reduce the overall data size for faster transmission.

To ensure the data can be handled by the protocol effectively. (correct)

To complicate the data transmission process.

To make the data encryption process easier.
