Evaluate the performance difference between two CPU architectures, CISC (Complex Instruction Set Computing) and RISC (Reduced Instruction Set Computing). Generally speaking, CISC CPUs have more complex instructions than RISC CPUs and therefore need fewer instructions to perform the same tasks. However, typically one CISC instruction, since it is more complex, takes more time to complete than a RISC instruction. Assume that a certain task needs P CISC instructions and 2P RISC instructions, and that one CISC instruction takes 8T ns to complete, and one RISC instruction takes 2T ns. Required:
Under this assumption, which one has the better performance?

1. so if i wanted to build a linux server for web services(apache) with 1cpu and 2 gb of memory.-operating at 75% of memory capacity2. a windows server with 2 cpu/ 4gb memory- operating at 85% of memory capacity3. a storage server with 1 cpu/ 2gb memory- operating at 85% of memory capacityhow much memory do i have to add for each server.so that the utilization rate for both cpu and memory is at a baseline of 60%."the details for the cpu like its processor or the memory's speed isnt to be concerned" yeah i kept asking my teacher if he's even sure about the but the whole class seems to be confused and the project is due in 3 days..this is a virtualization project where i have to virtualize a typical server into an exsi hypervisor.
