Question

Quizplus · Accepted Answer

To implement WAN technology to interconnect their regional offices to the corporate headquarters, David should suggest Frame Relay.
Key Takeaway: Frame relay puts data in a variable-size unit called a frame and leaves any necessary error correction up to the end-point, speeding up the overall data transmission. It is based on the older X.25 packet-switching technology that was designed for transmitting analog data such as voice conversations. It is often used to connect local area networks with major backbones, as well as on public-wide area networks and also in private network environments with leased lines over T-1 lines.
