Ethernet is a family of computer networking technologies for local area networks (LANs). Ethernet was introduced to the commercial marketplace in 1980, and has replaced other LAN technologies. It’s a baseband LAN specification invented by Xerox Corporation that operates at 10Mbps using carrier sense multiple access collision detection (CSMA/CD) to run over coaxial cable. Ethernet was designed to serve in networks with sporadic, occasionally heavy traffic requirements, and the IEEE 802.3 specification was developed in 1980 based on the original Ethernet technology. In simpler terms, 802.3 is the standard defining a wired network, known as Ethernet, whereas 802.11 defines a standard for wireless networking.

What impact will the continued evolution of the Ethernet standard have on data storage requirements, assuming capacity continues to follow the same pattern of progress?
I think Intel cofounder Gordon Moore’s prediction known as “Moore’s Law” will prove to be true. It states that the number of transistors on a chip will double approximately every two years. The announcement of the historic Intel 22nm 3-D Tri-Gate transistor technology assures us that the promise of Moore’s Law will continued to be fulfilled.

What network devices will be required for the configuration of a VLAN-enabled Ethernet network?
When dividing a local network into VLANs, you must obtain switches that support VLAN technology. You can configure all ports on a switch to serve a single VLAN or multiple VLANs, depending on the VLAN topology design.

What statement can be made about the rate of progression in data transfer capacity in Ethernet standards?
As stated in an article found in Infinera; Industry consensus has led to general agreement that a doubling of Internet traffic each year represents a sustainable natural growth rate [1, 2], with growth ranging from 75% to 125%...
