Fundamentals of memory

A collection of connected storage devices form the memory unit. It is a space to store data and instructions required for processing. Information is stored in a memory unit in the form of bits. There are two types of memory namely:

A processor uses a serial link to communicate with a keyboard for word processing. A typist using this keyboard can type at rates peaking at 120 words per minute, where a word is 6 characters (including spaces and punctuation). The characters will be transmitted from the keyboard in 8-bit ASCII with one stop bit and no parity. Only consider these and no special characters. The programmer writes setup and polling service routines based on a minimum baud rate, but then finds that the keyboard will only interface at 19.2 Kbaud. Will the polling service routine have to change? Why or why not? Baud Rates 300 600 1200 2400 4800 9600 19200

PROBLEM 1 For sorting a set of items, we can employ one of these famous algorithms, merge- sort, heapsort, quicksort, and shell-sort. We can program in both Java and Python, and we have the choice of using three different computers with different instruction set architectures: x86, ARM, and MIPS. Regarding microarchitecture, for x86 we have two choices, and for ARM and MIPS we have three choices for each of them. How many choices we have to run a sort algorithm? (Draw diagram).
