A memory component in a sequence processing model is updated using a First-In, First-Out (FIFO) rule. The memory has a fixed capacity of 3 segments. The current state of the memory, ordered from oldest to newest, is [Segment_A, Segment_B, Segment_C]. A new segment, Segment_D, is processed. According to the FIFO update rule, what will be the new state of the memory after the update?

A sequence processing model uses the formula Mem_new = FIFO(S_new, Mem_old) to update its fixed-size memory. Match each component of the formula to its correct description.

The formula Mem = FIFO(S_kv^k, Mem_pre) describes an update to a fixed-size memory buffer in a sequence processing model. Arrange the operations below into the correct chronological order that this formula represents.
