From one computer to the other... (week 3)

 

Back in the day, data transfer wasn’t as easy as it is now… we now have various ways we can send data from one computer to another without the need to have a computer directly connected together: whether it be Bluetooth, cloud services, email, or sharing files locally over a network.

Unfortunately, it never used to be this easy, at one point if you wanted to share data or transfer it from one computer to another you had to physically transfer the data. Meaning you would need to put the file on a storage device and then use that same storage device on the computer you wanted to add the file to. Eventually it upgraded to file or data transfers from one device to another by use of an ethernet cable

What intrigues me the most regarding ethernet file transfer is how the data moves… I have always been curious… does it just slide from one end to another, or maybe it’s portrayed like you see in the movie Ralph Breaks the Internet. Unfortunately… it’s not that cool! It’s actually sent as an ethernet frame, that is comprised of several different clusters, Destination, source, type, data, and FCS. In total an ethernet frame consists of 64 bytes; Interesting if the file or data transfer is smaller than the frame size, it adds in a filler to meet the requirements; otherwise known as a pad.
