Answer:
The missing piece of technology that prevented the audio production industry from using the electrical recording system earlier was a device that could amplify the electric signal. The device that made this possible was the Audion valve
Explanation:
The telephone system in the passage is able to convert sound to electronic signals in a crude manner, without amplification. The electrical recording system, whereby a microphone converted sound into amplified electrical signals was, made possible by the invention of the electronic valve, known as the Audion triode vacuum tube by Lee De Forest in 1906. Electrical sound systems were built based on the Audion tube before transistor-based audio equipment became commercially available in the 1950s.

Protocol
A network protocol is an established set of rules that determine how data is transmitted between different devices in the same network. Essentially, it allows connected devices to communicate with each other, regardless of any differences in their internal processes, structure or design. Network protocols are the reason you can easily communicate with people all over the world, and thus play a critical role in modern digital communications.
Answer:
Availability Goal
Explanation:
In Information Security, Countermeasures intended to ensure the uninterrupted availability of data and resources for authorized use promote the "Availability Goal".
The Availability goal is one of the the three main goals of Confidentiality, Integrity and Availability espoused within the CIA model of Information Security measures. Redundancy and Fault tolerance are means within the Availability model intended to mitigate against incidents like Denial of service (DoS), Loss of information system and Equipment failures, incidents that could all mean data and resource unavailability.
Answer:
Non repudiation.
Explanation:
Information security is a concept in information technology, whereby access to information, transmission and use of data are controlled for security purposes.
The access control countermeasures are preventive features to prevent access to information systems by attackers.
Non repudiation is an information security access control feature that prevents partners in business from denying emails delivered and signatures.
