VG-AnyLan (VG =Voice Grade) is a joint development of AT&T Microelectronics, Hewlett-Packard, and IBM and is standardized by the newly created IEEE. VG-AnyLAN is a star topology. The maximum amount of repeaters (HUBs) in one network is five. The maximum length of a complete network depends on the. Overview. VG-AnyLAN is a new network technology, defined by the IEEE standard, for transmitting Ethernet/IEEE and token ring/IEEE

Since there are only 16 balanced symbols available, 16 data paterns require two 6 bit symbols.

After saying what happened, and answering any questions, the discussion can return to farm subsidies. This makes it possible for time-critical applications such as real-time video to get a guaranteed support. The MII adds a preample, start frame delimiter and end frame delimiter.

Cables are discussed below. As the token passed by a ready hub port, it would then open up traffic to that node. Hubs may be cascaded up to three 3 deep. Retrieved from ” https: What ln the difference between computer xny and network communications?

It removed the token passing responsibility from the wiring and network nodes and placed it internal to the VG-AnyLAN hubs. The user of the network never even knows that it is happening, and doesn’t pan to do any special setup to make it work. Although it is completely different from Ethernet and Token Ring access protocols, the details are all taken care of in the software drivers that the customer loads on workstations and servers.


This is done a boot time. Broadband versus Baseband What is Ethernet? Now, if someone wishes to speak, he first raises his hand and waits to be recognized.

What is the difference between Wi-Fi vs. 100gg presented a problem with early installations that borrowed one unused twisted pair for telephone traffic but those installations were uncommon.

Dinesh authors the hugely popular Computer Notes blog. Type of bound transmission media Explain Unbound transmission media – What is Unbound transmission media.

They multiplexed the signal across all 8 wires thereby lowering the frequency and making it more robust. Another faction wanted to change to a polling architecture from the hub they called it ” Demand Priority Protocol ” in order to maintain the 10BASE-T distances, and also to make it a deterministic protocol.


All of the hubs in the network negotiate among themselves and schedule a time when they will allow the transmission to take place.

After being recognized, this person says his piece and then sits back down. The top level HUB root is called level 1 and every step down adds a level. The process the customer goes through to install them is exactly the same as if putting in Fast Ethernetor any other networking scheme.

Where he writes how-to guides around Computer fundamentalcomputer software, Computer programming, and web apps. This maximizes network efficiency, eliminates network collisions and token rotation delays. This had the additional advantage of being less susceptible to external sources of RF interference such as other network cables, fluorescent lights, and high power lines.

Each HUB maintains a list of high- and normal-priority requests. Returning to our meeting example, let’s say that the House is discussing a mundane topic such as farm subsidies and all of a sudden the Navy is attacked by aliens from Space. Transmission Media What is Congestion Control? Everything is now ready for transmission.
