Ethernet cables are the physical encapsulated wiring for data transmission. Compared to wireless LAN (WLAN) technology, Ethernet is generally less susceptible to outages. It also provides a greater degree of network security and control than wireless technology because devices must be connected using physical wiring. This makes it difficult for outsiders to access network data or hijack bandwidth from unauthorized devices.<\/p><p>The original 10BASE5 Ethernet used coaxial cable as a shared medium, while newer Ethernet variants use twisted pair and fiber optic links in conjunction with switches. Over the course of its history, Ethernet data rates have increased from the original 2.94 Mbit\/s to the latest 400 Gbit\/s, with rates of up to 1.6 Tbit\/s under development, a process that can be completed in 14 minutes if we have 500 TB of data to send. The Ethernet standard includes several cabling and signaling variants of the OSI physical layer.<\/p><h2 class=\"wp-block-heading\">Development History<\/h2><ul class=\"wp-block-list\"><li>It was inspired by<a href=\"https:\/\/baike.baidu.com\/item\/ALOHA%E7%B3%BB%E7%BB%9F\/22785620\" target=\"_blank\" rel=\"noreferrer noopener\" class=\"broken_link\">ALOHAnet<\/a>(The ALOHAnet protocol was born in June 1971 at the University of Hawaii's Manoa School of Engineering and is the basis for all wireless communications such as mobile, satellite, cellular and WiFi) Robert Metcalfe studied ALOHAnet in 1973 for his Ph.D. The luminous Ether, after which he was named, was once postulated to be \"a ubiquitous, totally passive medium for the propagation of electromagnetic waves\"<\/li><li>In 1975 at Xerox (<a href=\"https:\/\/www.parc.com\/\" target=\"_blank\" rel=\"noreferrer noopener\">Xerox PARC<\/a>) was invented by Robert Metcalfe and David Boggs and upgraded from the original 2.94 Mbit\/s protocol to the 10 Mbit\/s protocol.<\/li><li>Metcalfe left in June 1979<a href=\"https:\/\/www.xerox.com\/en-us\" target=\"_blank\" rel=\"noreferrer noopener\">Xerox<\/a>The establishment of the<a href=\"https:\/\/www.3com.tel\/\" target=\"_blank\" rel=\"noreferrer noopener\">3Com<\/a>The company persuaded Digital Equipment Corporation (DEC, acquired by Compaq in January 1998), Intel and Xerox to work together to promote Ethernet as a standard.
