The Multimedia over Coax Alliance (MoCA) is an international standards consortium that publishes specifications for networking over coaxial cable.The technology was originally developed to distribute IP television in homes using existing cabling, but is now used as a general-purpose Ethernet link where it is inconvenient or undesirable to replace existing coaxial cable with optical fiber or ...
The first Ethernet standard, known as 10BASE5 (ThickNet) in the family of IEEE 802.3, specified baseband operation over 50 ohm coaxial cable, which remained the principal medium into the 1980s, when 10BASE2 (ThinNet) coax replaced it in deployments in the 1980s; both being replaced in the 1990s when thinner, cheaper twisted pair cabling came to dominate the market.
In March 1986, Hitron founded on agency of electronic equipment. It begin with 9 employees and NT$8,000,000 in capital. In 1987, Hitron entered IT and communication industries. In 1989, Hitron entered in the field of GIS. In 1996, Hitron constructed HtNet to provide dial-up internet access service as an Internet service provider. The URL is www ...
An AC adapter or AC/DC adapter (also called a wall charger, power adapter, power brick, or wall wart) [1] is a type of external power supply, often enclosed in a case similar to an AC plug. [2] AC adapters deliver electric power to devices that lack internal components to draw voltage and power from mains power themselves.
An adapter card or expansion card is a circuit board which is plugged into the expansion bus in a computer to add function or resources, in much the same way as a host bus adapter (see above). [ 3 ] [ 1 ] Common adapter cards include video cards , network cards , sound cards , and other I/O cards.
[7]: 40 By definition, each end of this "adapter" has a different connection method – e.g. the solder tabs on a male phone connector, and the male phone connector itself. [3] In this example, the solder tabs connected to the cable represent the permanent connection, whilst the male connector portion interfaces with a female socket forming a ...
In 1941, the US Navy used a smaller version of the threaded N connector, the Type BN (Baby N), as the UG-85/U, UG-86/U, UG-114/U and UG-115/U. . In 1943, the British introduced a ¼ inch 50 ohm coaxial cable, and companies immediately developed many connectors for it.
Although the plug is female, with a partially recessed center contact, it is still possible for casual accidental contact with a metallic object to short-circuit the power source. Depending on the design of the power adapter, it may react to a short circuit by shutting down temporarily, or instead by blowing out an internal safety fuse.
