The document discusses pseudo code, which is a way to write algorithms using simple English statements that are easily understood. It can be used to describe the steps of a computer program process. Examples are given of pseudo code for tasks like adding two numbers, calculating the area of a triangle, finding the average of data values, determining a student's grade based on their score, and a program that adds input numbers in a loop until the total exceeds 1000. Key elements of pseudo code like variables, conditional statements, and loops are also explained.
