Power line networking is one of the options in connecting computers to form a home network. This technology powers a "wireless" and "power free" home network. Power line networking does not require the user to install additional cables and power-consuming networking hardware to set up a home network. Instead, power line networking, uses the existing …
An Analog Telephone Adapter (ATA), also known as the Analog Telephony Adapter, is an electronic device used to enable one or more analog telephones or facsimile machines for Voice over Internet Protocol (VoIP) calls and faxes. An Analog Telephone Adapter basically creates a physical connection by use of telephone and Internet cables between a conventional …
A smart antenna is one that transmits or receives multiple radio frequencies at once. Smart antennas increase data transfer rates and reduce errors by handling several copies of the same information. Conventional antenna systems consist of one antenna that serves as a transmitter and one that serves as a receiver. This is starting to change, …
CSMA/CD (Carrier Sense Multiple Access / Collision Detection) is the protocol used in Ethernet networks to ensure that only one network node is transmitting on the network wire at any one time. Carrier Sense means that every Ethernet device listens to the Ethernet wire before it attempts to transmit. If the Ethernet device senses that …
CCMP (Counter Mode with Cipher Block Chaining Message Authentication Code Protocol) is the preferred encryption protocol in the 802.11i standard. CCMP Cryptography CCMP is based upon the CCM mode of the AES encryption algorithm. CCMP utilizes 128-bit keys, with a 48-bit initialization vector (IV) for replay detection. The Components of CCMP The Counter Mode (CM) …
The Unix/Linux `traceroute` command and the Microsoft Windows `tracert` commands both accomplish the task of tracing network paths, but they do it in slightly different ways. Both of these tools for tracing network routes send out a packet wth TTL (Time To Live) set to 1 and report it’s destnation. Then, they send out a …
Every office and small business needs a method of running multiple communication programs such as conference calling, video conferencing, media distribution, instant messaging, and account management software. To perform these tasks, servers need the help of a SIP gateway to bridge the gap between data streams and the Internet. SIP gateways are also essential in …
WCDMA (Wideband Code Division Multiple Access) is the radio access scheme used for third generation cellular systems that are being rolled out in various parts of the globe. The 3G systems support wide band services like high speed Internet access and video and high quality image transmission with the same quality as the fixed networks. …
Fiber optic patch panel, also known as the fiber distribution panel, is used mainly in fiber optic cable management. It helps network technicians in minimizing the clutter of wires when setting up fiber optic cables. It terminates the fiber optic cable while providing access to the cable’s individual fibers for cross connection. They are also …
