Final answer:
The subject of this question is Computers and Technology and the grade level is High School. When implementing a public telecommunication switching system, such as a frame relay cloud, the technology used is packet switching. This allows for efficient data transmission and communication between different locations.
Step-by-step explanation:
The subject of this question is Computers and Technology and the grade level is High School.
When implementing a public telecommunication switching system, such as a frame relay cloud, the technology used is packet switching. In packet switching, data is divided into small packets and transmitted over the network individually, allowing multiple packets to be transmitted simultaneously. This increases efficiency and makes it possible to transmit data over long distances.
For example, in a frame relay cloud, data is encapsulated into frames and transmitted between the sender and the receiver using virtual circuits. The frames are then routed through the network to reach their destination. This allows for efficient utilization of network resources and enables effective communication between different locations.
