Document Summary

Csci 1120: introduction to computer systems- lecture 2: Understand and translating binary value in two"s complement format into integer value in decimal and vice-versa. How many values can be expressed given n-bits where n is an element of natural numbers. What is the maximum value that can be expressed given n-bits where n is an element of natural numbers. *the number of possible values is the same across any format of information encoding; as such it is usually not what one refers to when talking about expressivity. A way of encoding that allows for the expression of integers values, to have both positive and negative values, instead of just having the positive integers (natural numbers) be its range of values. In order to identify the positive and the negative, the left-most bit is used as the sign, with. If the number is positive, it follows the convention as the natural numbers (as noted in.
