Explore how computer systems store, manipulate, and convert various data types like text, images, and videos through integrated software and hardware. Gain insights into accessible data representation.

Computer systems do not understand human instructions, nor can they perceive real-life data in its raw form. Therefore, computer systems require a way to store and represent information in an accessible way. They use software and hardware components combined to help retrieve information, store it, manipulate it, and convert it back to a human-accessible format. If you want to learn how computer systems perform complex tasks such as storing and manipulating textual data, videos, music, images of your cat, and much more, this course is meant for you.

Information Representation in Computer Systems

import numpy as np

def thirdElement():
    arr = np.array([1, 2, 3, 4, 5])
    thirdEl = arr[2]
    return thirdEl

## Explanation
> Note: The first position in an array is at index 0 and not at index 1.

The third element in the array is 3 and it is found at index 2.
