Specified in a standard, IEEE 802.3, Ethernet was originally developed by Xerox from an earlier specification called Alohanet (for the Palo Alto Research Center Aloha network) and then developed further by Xerox, DEC, and Intel.
![]() Ethernet was so- named to describe the way that cabling, also a passive medium, could similarly carry data everywhere throughout the network. Some Ethernet networks use coaxial cables, but thats rarer, and present in rather large LANs, which span over areas between buildings. If you want to see what a coaxial cable is like, look at the thick cable that links your TV antenna to your TV set. Serial Vs Ip Install On YourIt is so popular that if you buy a network card to install on your machine, you will get an Ethernet card, unless you ask for something different, if of course that different protocol is available. Today, you can get cheap Ethernet LAN cards with speeds up to 100 Mbps; while the fastest Ethernet reaches Gbps (1 Gbps 1000 Mbps) in speed. It is usually contrasted with parallel, meaning more than one event happening at a time. In data transmission, the techniques of time division and space division are used, where time separates the transmission of individual bits of information sent serially and space (on multiple lines or paths) can be used to have multiple bits sent in parallel. This indication doesnt always hold since a serial medium (for example, fiber optic cable) can be much faster than a slower medium that carries multiple signals in parallel. Your keyboard and mouse are one-way devices that only require a serial interface and line. Inside your computer, much of its circuitry supports bits being moved around in parallel. Serial communication between your PC and the modem and other serial devices adheres to the RS-232C standard. However, some of todays computers have multiple processors and can perform instructions in parallel. ![]() In this edition of How Stuff Works, you will learn about the difference between a parallel port and a serial port, what each pin does and what flow control is. A serial port is a general-purpose interface that can be used for almost any type of device, including modems, mice, and printers (although most printers are connected to a parallel port).
