What does Download Speed, Upload Speed, and Latency Mean?

Download speed is the speed that information on the Internet (e.g., text and graphics) is transferred to your computer; that is, how long it takes your computer to load websites and download files to display on your screen. Upload speed is the speed that your computer can transfer or send information to the Internet. For example, if you want to send photos to a website to be printed by your local vendor, you “upload” the photos to the site. Download speeds normally happen at faster speeds than uploads; however, that can depend on broadband connections or how web pages are created.

Latency is the amount of time it takes for a small packet of information sent from your computer to reach another computer on the Internet, and then return back to you. This measurement is also referred to as Ping and is measured in milliseconds (ms)2. When you send information from your computer (click a link, type in a web address, send an email) it waits for confirmation that the data packet was received, thus “latent” time. Latency and bandwidth are the two factors that determine the speed of your network connection.
