What terms represent the maximum and actual speed that can be utilized by a device to transfer data?

The terms that represent the maximum and actual speed that can be utilized by a device to transfer data are "Bandwidth" and "Throughput" respectively.

1. Bandwidth: This is the maximum data transfer rate of a network or internet connection. It measures how much data can be sent over a specific connection in a given amount of time. For example, a gigabit Ethernet connection has a bandwidth of 1,000 Mbps (megabits per second).

2. Throughput: This is the actual speed that can be achieved by a device to transfer data. It is often less than the maximum bandwidth due to various factors like network congestion, physical distance, and the quality of the connection. For example, you might have a gigabit Ethernet connection (bandwidth of 1,000 Mbps) but only be able to achieve a throughput of 600 Mbps due to these factors.
