An instruction pipeline consists of $$4$$ stages: Fetch (F), Decode field (D), Execute (E), and Result-Write (W). The $$5$$ instructions in a certain instruction sequence need these stages for the different number of clock cycles as shown by the table below.

Find the number of clock cycles needed to perform the $$5$$ instructions

The main difference (s) between a $$CISC$$ and a $$RISC$$ processor is/are that a $$RISC$$ processor typically:

RAID configurations of disks are used to provide

Let $$R=(A,B,C,D,E,F)$$ be a relation scheme with the following dependencies: $$C \to F,\,E \to A,\,EC \to D,\,A \to B.$$ Which of the following is a key for $$R?$$
