Exercise 2

A computer has a word width that allows you to represent numbers in complement to two in the range [-234, 234-1]. Answer the following questions:
  1. What is the number of bits that store the registers of this computer?
  2. How much KB of memory can address at most this computer?

Exercise 3

Exercise 4

Represent in the single precision IEEE 754 standard the numbers 15 and 3,75.

Exercise 5
