What are the main types of Fast Ethernet and their uses?
Fast Ethernet primarily comes in two main types: 100Base-TX and 100Base-FX, each designed for specific networking environments. 100Base-TX utilizes copper cabling (Cat5e) for local area networks (LANs), connecting devices like computers and printers over shorter distances, supporting full/half duplex at 100 Mbps. In contrast, 100Base-FX employs fiber optic cabling, offering higher bandwidth and transmitting data over much longer distances (up to 120 kilometers), suitable for connecting networks across buildings.
- 100Base-TX (Copper):
- Uses Cat5e cables for LANs.
- Supports 100 Mbps, full/half duplex.
- Connects computers and printers.
- 100Base-FX (Fiber Optic):
- Utilizes fiber optic cabling.
- Enables long cables (up to 120 Kms).
- Offers higher bandwidth, connects across buildings.
Why is Fast Ethernet significant for modern networks?
Fast Ethernet holds significant importance for modern networks due to its ability to deliver increased data transfer rates and enhance overall network performance.
