Which type of Ethernet network offers transfer rates up to 100 Mbit/s?

Fast Ethernet is the type of Ethernet network that offers transfer rates up to 100 Mbit/s. This technology represents an advancement over the original Ethernet standard, which supported only 10 Mbit/s. Fast Ethernet was developed to accommodate a growing need for higher bandwidth in local area networks (LANs), allowing for a more efficient transfer of data and support for more demanding applications.

Fast Ethernet uses the same frame format as standard Ethernet, allowing for compatibility in mixed environments. While Gigabit Ethernet and 10 Gigabit Ethernet significantly increase transfer rates beyond 100 Mbit/s, they are not applicable to the question since they exceed the specified limit. Standard Ethernet, on the other hand, operates at a much lower rate of 10 Mbit/s. Thus, Fast Ethernet clearly stands out as the correct choice for the specified transfer rate of up to 100 Mbit/s.
