1) Memory Architecture and Management

A. Among the following memories in order of their access latency (speed) from faster to slower: SRAM, Register, HDD, DRAM B. Why do we need different partitions (e.g., boot, root, etc.)? C. What are the pros and cons of NOR and NAND flash memories?

2) Computer Arithmetic
