What unit is used to measure network speeds?

The correct choice is bits because network speeds are typically measured in bits per second (bps). This metric reflects the number of bits transmitted over the network in one second. Network speed is a crucial aspect of networking as it determines how quickly data can be sent and received, influencing performance for tasks such as streaming, downloading, and video conferencing.

While bytes and megabytes are units that can measure data size, they are not primarily used for measuring transmission speed. Packets represent a formatted unit of data carried over a network, but they don't convey the rate at which data travels. Therefore, when discussing the speed of a network connection, bits is the standard unit that accurately describes how quickly information can flow across a network.
