Frame Relay is a standardized wide area network (WAN) technology that specifies the physical and data link layers of digital telecommunications channels using a packet switching methodology. It's designed for efficient data transmission between LANs or endpoints over a wide area. Frame Relay is commonly used for connecting branch offices to a central office or data center, providing a cost-effective solution compared to dedicated leased lines, though it has largely been replaced by more modern technologies like MPLS and broadband internet.
