This lesson will explain the process of data transfer throughout computer systems and the form the data gets transferred into. Additionally, we will touch on some factors that alter the transfer speed. We will use simple analogies and examples to explain complicated concepts. We will present a situation where a mailman has five packages to deliver and he is constrained by time to deliver them. We will also include an analogy that includes running with a folder through the hallways of a school to deliver it to a certain office by using a relay system with different students taking turns at the task. Those two examples and their solutions will help the students understand the basics of data transfer and the factors affecting the speed at which that happens. Students will learn to calculate the time it takes to transfer folders and files after knowing their respective sizes. Prerequisites for this lesson include some knowledge of the concept of digital data and an understanding of file size units (Bits, Bytes, Kilobytes, etc). Materials needed include: 5 Cardboard boxes in different sizes; Stickers; a series of books; and 3 bags.
