Think of it like pouring water into a beaker. Uploading and downloading data can take a while, depending on the file's size and transfer rate. Then, to access our file, people have to download it to their devices. All we need to do is upload our file to the internet. With the internet, we can now easily send any file to our loved ones, even if they are a thousand miles away from us, as long as they also have access to the internet. The internet is a series of computer networks running all across the world. We can now also upload or transfer data to the internet so that other people can access it. Nowadays, we can also transfer data wirelessly through radio frequencies like Bluetooth or Wi-Fi. The simplest way to transfer a file is through a data cable specifically made to transmit data. With that said, several ways have been developed for us to be able to transfer digital files from one device to another.
When we take a picture using a digital camera, we need to have a way to transfer the picture file to a computer and then to a printer to end up with the image printed on a piece of paper. Files cannot always be in just one computer or machine.
