The term upload denotes the process of data being transferred off of a digital device via a remote connection – typically the Internet. The term is most widely used to indicate the speed at which data can be transferred from a device to an Internet server.
Upload speeds are typically measured in bits transferred per second (bps). Common indicators of upload speeds include Kbps (Kilobits per second), Mbps (Megabits per second) and Gbps (Gigabits per second). The term download denotes the transfer of data in the opposite direction – onto one digital device from another device via a remote connection.
Transferring large amounts of data to cloud-based storage from your phone or computer or moving video data to remote streaming services like YouTube are two examples of activities which benefit from high upload speeds.
The data connections offered by many telecom service providers are asymmetrical, meaning upload speeds are lower than download speeds. Asymmetrical data connections are disadvantageous for consumers who transfer large amounts of data over the Internet. Some telecom service providers offer symmetrical data connections, with identical upload and download speeds.
