What speed does CAT5 cable support?

10 Mbps
100 GB/sec
100 MB/sec
1 Gbps

The correct answer is: 100 MB/sec

CAT5 cable supports a maximum speed of 100 MB/sec, which is the equivalent of 0.1 GB/sec, not to be confused with 100 GB/sec as mentioned in option B. While option A states 10 Mbps, this is an incorrect measurement as it is most commonly referred to as 10/100 Mbps (Megabits per second). Similarly, option D is also incorrect as it lists the speed in Gbps (Gigabits per second), which is much higher than the maximum speed of CAT5 cable. Therefore, option C is the only accurate depiction of the speed that CAT5 cable can support.
