mémoire DDR SDRAM(A type of SDRAM that supports data transfers on both edges of each clock cycle (the rising and falling edges), effectively doubling the memory chip's data throughput)
échange synchrone de données(A style of processing where an application requests that an event occurs and waits for the event to complete, so that the application is certain of the result of its request before it proceeds)
protocole SDLC(A type of link service used for managing synchronous data transfer over standard telephone lines (switched lines) or leased lines. The data transmission protocol most widely used by networks conforming to IBM's Systems Network Architecture (SNA). SDLC is similar to the HDLC (High-level Data Link Control) protocol developed by the International Organization for Standardization (ISO))
