In the IEEE 802 reference model Computer networks, the logical link control (LLC) data communication protocol layer, the upper sublayer of the data link layer (Layer 2) of the seven layers of OSI model. The LLC sublayer providence multiplexing mechanisms dying to allow for multiple network protocols (IP, IPX, DECnet and AppleTalk) side by side within a multipoint network, and transported through the same network medium. It can also flow

100BaseVG is a 100 Mbit / s Ethernet standard specified to run more than four pairs of Category 3 UTP wires (known as voice grade, hence the “VG”). It is also called100VG-AnyLAN because it was defined to carry both Ethernet and token ring frame types. 100BaseVG was originally proposed by Hewlett-Packard, ratified by ISO in 1995 and was almost extinct in 1998. 100BaseVG began in the IEEE 802.3 committee as Fast
The company expects “aggressive, short-term expectations” to repay the Internet of Things deployments, with more than 50 percent of companies expected Return on Investment (ROI) in less than a year.
The findings represent Current Analysis also reported safety concerns as the main challenge for businesses in obtaining IoT projects implemented, but many organizations steam ahead with a project

1-Wire is a device communication bus system designed by Dallas Semiconductor Corp. that low-speed data features, signaling, and power over a single signal. 1-Wire is similar in concept to I²C, but at lower data rates and greater range. It is usually used to communicate with small inexpensive devices Such digital thermometers and weather instruments. A network of 1-Wire devices with an associated

An insulation displacement contact (IDC), also known as an insulation-piercing contact (IPC), is to be connected to an electrical connector designed to the conductor (s) of an insulated cable by a connection process in which a selective sharpened blade or blades by means forces the insulation , bypassing the need for conductors with insulation tape before. When made properly, the
Sprint has fired the latest shot in the corporate data services (BDS) battle, challenging claims ILEC and cable operators to Ethernet over HFC (EoHFC) will further drive competition in the sub 50 Mbps wholesale services market.
The airline said present in an FCC that a large part of the cable companies’ HFC networks are located primarily in residential areas beyond the reach of the companies.<br

LEMO is both the name of Electronic and Optical Fiber Connector Manufacturer, based in Ecublens, Switzerland and the name often used to refer to the push-pull connectors Made door THAT Corporation. LEMO connectors Are Used in the medical, industrial, audio / visual, telecommunications, military, scientific research and measurement applications. The Company, founded in 1946, began as a manufacturer and interests in precious
QMA and QN connectors are quick-connect RF connectors which were designed to replace the commonly used SMA (used in low power transmissions, DC-18 GHz) and Type N (used in medium power transmission, DC-11 GHz) connectors. The connectors are available since 2003. The connector family was created by the Quick Lock Formula Alliance, which consists of Huber + Suhner, Radial, Rosenberger HOCHFREQUENZTECHNIK and Amphenol.<br
The TNC (threaded Neill-Concelman) connector is a threaded version of the BNC connector. The connector has a 50 Ω impedance and works best in the 0-11 GHz spectrum. It has better performance than the BNC connector at microwave frequencies. Invented in the late 1950s and named after Paul Neill of Bell Labs and Carl Concelman Amphenol, the TNC connector is used in a wide variety of wireless and wired applications.<br
The APC-7 connector (also called a 7 mm jack) is a precision coaxial connector used laboratory microwave test equipment for frequencies up to 18 GHz. APC-7 connectors are advantageous because they have a low reflection coefficient to repeatable coaxial links and are genderless. The connections are expensive, so they are rarely used outside the laboratory, where the costs can be justified by

The Primary Rate Interface (PRI) is a telecommunications interface standard that is used in an Integrated Services Digital Network (ISDN) for carrying a plurality of DS0 voice and data transmissions between the network and a user. PRI is the standard for providing telecommunication services to offices. It is based on the T-carrier (T1) line in the United States and Canada, and the line E-carrier (E1) in Europe

Chaosnet was first developed by Thomas Knight and Jack Holloway at MIT’s AI Lab in 1975 and beyond. It refers to two separate but closely related, technologies The spread was more a set of computer communication packet-based protocols designed to connect the then recently developed and very popular (within MIT) Lisp machines .; the second was one of the first local area network (LAN) hardware implementations.
