When we “download” something – we are bringing “it” from the source we are connected to on the Internet to our computer. Such as, we might "download" music, videos or photos from a website we are visiting to our computer so that we can save it for future use. It is very common today to purchase software from an online store or source and then “download” the software to our computer. In all cases – when you download something – the original remains at the source you are copying it from. You are downloading a copy - never the original.
When we “upload” something we are sending a copy of “it” from our computer to the source we are connected to on the Internet…- such as when we want to order or share photos, we will “upload them” or send a copy of them to Walgreens, CVS or Picasa web albums so that we can then access them from anywhere in the world; when you add an "attachment" to an email, a copy of the original is being "uploaded" and attached it your email.. In all cases – when you upload something – the original remains on your computer – it is simply a copy of that original that is uploaded and sent to the source
