## Article

## **Introducing Ethernet**

Traditional Ethernet supports data transfers at the rate of 10 megabits per second. As the needs evolved with time additional new Ethernet specifications have been developed by industry for Fast Ethernet and Gigabit Ethernet. Fast internet has speed up to 100Mbps and Gigabit Ethernet has speed of 1000Mbps. Ethernet cables are also prepared for specific standards. CAT 5 is the most popular cable which supports both traditional and Fast Ethernet. The CAT 5e and CAT 6 cables support Gigabit Ethernet. To connect Ethernet cables to a computer or other network device, a person plugs a cable directly into the device’s Ethernet port. Some devices without Ethernet supports can also support Ethernet connections through USB to Ethernet Adapters which are called dongles.
