Frame Relay is a type of wide area network (WAN) technology that enables the efficient transmission of data between multiple locations. It uses a packet-switching method, where data is divided into smaller packets and sent over a shared network. This allows for faster communication and better use of bandwidth compared to traditional circuit-switched networks. In Frame Relay, data packets are sent through virtual circuits, which are established between devices. This technology is particularly useful for businesses that need to connect remote offices or branch locations, as it provides a cost-effective solution for transmitting data over long distances while maintaining reliable performance.
