10Answer the following: a. Explain the memory hierarchy of a computer system. Discuss registers, cache memory, main memory, and secondary memory in terms of speed, capacity, cost, and access time. Also explain the concept of memory address mapping. [6.5] b. Explain the major components of the 8086 microprocessor. Discuss the functions of the Bus Interface Unit, Execution Unit, segment registers, instruction pointer, general-purpose registers, and instruction queue. [6] OR Compare isolated I/O and memory-mapped I/O in terms of address space, instructions used, control signals, available I/O addresses, and system complexity with suitable examples.
