Computer Architecture and Organization

Question 1: Answer each of the following briefly: (5 Marks) a) Which memory mode addressing only the first IM byte of memory space-even in Pentium 4 or Core2 microprocessor? b) In computer systems, which bus type requests a memory location from the memory or an 10 location from the 10 devices. c) What is the name of a collection of tracks located in the same location on a set of hard disk surfaces? d) Is it true or false that most computer operations are executed in the arithmetic and logic unit (ALU) of processors? e) Which instruction reads a data operand from a processor register to memory or an output device. When multiple processing units are fabricated on a single chip, what does this processor called? ) What is the name of time that is the sum of the seek time and the rotational delay time in magnetic hard drives? h) Is it big-endian or little-endian addressing assigns lower byte addresses to more significant (leftmost) bytes of the word? 1) Which addressing mode is considered as the least used addressing mode? j) In 32-bit microprocessors, what is the memory space that can be addressed
