Westell is a provider of DSL routers and other DSL-based devices that telephone companies and DSL subscribers use for wireless Internet in homes or offices, instead of using cable or satellite Internet. Westell products generally have the same features as other routers, such as dual antennas, four Ethernet ports, and WPA encryption, but connect to the Internet through a telephone wire.
The Westell wireless router has been used since mid-2004 as BellSouth's default Internet router. The router

VLAN Hopping is one of the primary VLAN based attacks used by hackers to infiltrate network security. VLAN hopping is used to attack a network by sending packets to a port which is generally not accessible. VLAN hopping attacks are mainly conducted in the Dynamic Trunking Protocol and, in some cases; the attacks are targeted to the trunking encapsulation protocol (802.1q or ISL). The Dynamic Trunking Protocol is utilized for negotiating trunking on links between devices and the type of trunking

A single mode fiber is a fiber optical cable that uses only one ray of light known as a “mode”. A single mode fiber can be used to transfer data in either direction at incredibly fast speeds and may stretch along hundreds or even thousands of kilometers. These factors allow single mode fibers to provide large office buildings, warehouses, and other areas with large numbers of computers to maintain fast speeds and reliable connections on all computers connected to the network.

802.1Q is also known as IEEE 802.1Q or VLAN tagging. It defines a virtual local area network. It is a protocol that allows virtual LANs to communicate with one another using a 3-layered router. It was developed as a part of IEEE 802.
Why Was The 802.1Q Standard Developed?
Large networks use up a lot of bandwidth and are slow. It is desirable to break up these huge LANs into smaller, more manageable networks. To address this problem, the 802.1Q standard was developed as a part of IEEE 802. This

Netgear routers are some of the most popular routers in the world, providing both residential and commercial users with wireless networks that are accessible from a wide variety of mobile devices such as laptops, tablets, smartphones, and even desktop computers that are outfitted with a wireless adapter (which Netgear also sells).
Netgear routers are available in 802.11b, 802.11g, and 802.11n standards, each of which is backwards compatible with previous standards. Netgear routers are very ea

This cable can be used to connect a parallel printer to the parallel port on a PC. The phrase parallel cable can be ambigous as it shelters numerous different specifications, not all of which are simple PC to printer type. The parallel port socket on a computer uses 25 pins. There are two types of parallel printer cable that are widely used for PCs. The old "standard" IBM Printer cable and the newer IEEE 1284 bi-directional cable commonly sold today.

Users can connect to a Linksys router manually by attaching an Ethernet cable from the router to a computer and typing 192.168.1.1 (the default IP address) in the web browser. This kind of connection is used to setup a router for the first time or troubleshoot problems when a wireless connection is not available. By default, the username and password are "admin" and "password" respectively, but can be changed once the user is logged into the Linksys interface.

A dial-up connection is any connection that is connected through a regular phone line. When that phone line is connected to a modem and then configured to dial a specific number, a user can access the Internet. It is the slowest form of Internet connection, but that is a result of also being the most inexpensive--if not free--form of Internet access available to users. According to a Pew Internet and American Life Project conducted in 2008, only about 10% of Americans were still using dial-up ei

SerDes (pronounced sir-dees) stands for Serializer/Deserializer. It is a set of blocks that is commonly found in high speed communications. SerDes' general purpose is to compensate for limited input/output. The blocks can convert data between serial data and interfaces that are parallel in different directions.
Functions of SerDes
The generic function is made up of two blocks:
Parallel In Serial Output (PISO)
Serial In Parallel Output (SIPO)
Additionally, there are four different SerD

Tunneling is a way in which data is transferred between two networks securely. All the data being transferred is fragmented into smaller packets or frames and then passed through the tunnel. This process is different from a normal data transfer between nodes. Every frame passing through the tunnel will be encrypted with an additional layer of tunneling encryption and encapsulation, which is also used for routing the packets to the right direction. This encapsulation would then be reverted at the
