The Windows Server operating systems supported AppleTalk starting with Windows NT and ending after Windows Server 2003. Miramar included AppleTalk in its PC MacLAN product which was discontinued by CA in 2007. GroupLogic continues to bundle its AppleTalk protocol with its ExtremeZ-IP server software for Macintosh-Windows integration which supports Windows Server 2008 and Windows Vista as well prior versions. HELIOS Software GmbH offers a proprietary implementation of the AppleTalk protocol stack, as part of their HELIOS UB2 server. AppleTalk was so easy to use that ad hoc networks tended to appear whenever multiple Macs were in the same room. Apple introduced the AppleTalk PC Card in early 1987, allowing PCs to join AppleTalk networks and print to LaserWriter printers. This could be as simple as a network of Ethernet Mac II's trying to talk to a LaserWriter that only connected to LocalTalk. KNX is not based on a specific hardware platform and a network can be controlled by anything from an 8-bit microcontroller to a PC, according to the demands of a particular building. Since it used the second pair of wires, network devices could even be connected through existing telephone jacks if a second line was not present.

After considering that his artificial line simulators used lumped components rather than the distributed quantities found in a real line, he wondered if he could not insert the inductance with lumped components instead of using Stone's distributed line. Western Union Telegraph Co. Western Union were in competition with AT&T and the Western Electric Company who were using permalloy. Since Pupin's patent contained a (less accurate) formula, AT&T was open to claims of incomplete disclosure. 1894, filed December 1893) which is sometimes cited as Pupin's loading coil patent but is, in fact, something different. In the same year Johann Schweigger invented the galvanometer, with a coil of wire around a compass, that could be used as a sensitive indicator for an electric current. Campbell, G A, "Physical Theory of the Electric Wave-Filter", Bell System Tech J, November 1922, vol. In c. 1915, Oliver E. Buckley, H. D. Arnold, and Elmen, all at Bell Labs, greatly improved transmission speeds by suggesting a method of constructing submarine communications cable using permalloy tape wrapped around the copper conductors.

IEEE Transactions on Cable Television. CATV (cable television), HDTV (high definition television), VoIP (voice over internet protocol), and broadband internet are some of the most common applications now being supported by fibre optic networks, in some cases directly to the home (FTTh - Fibre To The Home). Mu-metal cable is easier to construct than permalloy cable, the mu-metal being wound around the core copper conductor in much the same way as the iron wire in Krarup cable. Renfrew leading to a Charles Marshall of Renfrew being suggested. The physical phenomena on which the device relies (such as spinning platters in a hard drive) will also impose limits; for instance, no spinning platter shipping in 2009 saturates SATA revision 2.0 (3 Gbit/s), so moving from this 3 Gbit/s interface to USB 3.0 at 4.8 Gbit/s for one spinning drive will result in no increase in realized transfer rate. Accordingly, this page lists both the internal ribbon and external communications cable standards together in one sortable table. Permalloy cable enabled signalling speed on submarine telegraph cables to be increased to 400 words/min at a time when 40 words/min was considered good. Loading coils solve the dispersion problem, and the first use of them on a submarine cable was in 1906 by Siemens and Halske in a cable across Lake Constance.

Earlier transatlantic submarine cables installations were attempted in 1857, 1858 and 1865. The 1857 cable only operated intermittently for a few days or weeks before it failed. Continuous loading of cables is expensive and hence is only done when absolutely necessary. The very first demonstration of loading coils on a telephone cable was on a 46-mile length of the so-called Pittsburgh cable (the test was actually in Boston, the cable had previously been used for testing in Pittsburgh) on 6 September 1899 carried out by Campbell himself and his assistant. Emily Steel; Mark Scott (September 17, 2015). "Expanding in U.S., Altice Plans to Buy Cablevision for $17.7 Billion". AppleBus is mentioned by name in Steve Jobs' introduction of the Macintosh at the Boston Computer Society meeting in 1984. It appears just after the 7:20 mark in the video. Essentially, serial ports provide a standard connector and protocol to let you attach devices, such as modems, to your computer. Some other computer architectures use different modules with a different bus width. The CAN bus also takes inputs from the rain sensor to trigger the rear windscreen wiper when reversing.
