Internet speed refers to the speed at which you send or receive data from your computer, phone or other device. Download speed is the rate your connection receives data. Upload speed is the number of bytes per second you can send. Data includes text, audio files and photos.
The download speed is typically much faster than the upload speed. The price you pay for Internet access with most devices is based on the maximum number of bytes per second the service provides, although cellular carriers charge by the total bytes transmitted. You can use websites such as Band Width Place and Speed Test to measure your computer's connection speeds. Apps such as Speed Test and Internet Speed Test do the same for phones.
