      DOCSIS (Data Over Cable Service Interface Specification)

      Data Over Cable Service Interface Specification (DOCSIS) defines the interface standards for cable modems and supporting equipment involved in high speed data transfer and distribution over cable television system networks. It permits additional high-speed data transfer over an existing cable TV system and is widely used by television operators to offer Internet access through an

One reason that many people decide to set up a wireless network is to share a internet connection. By setting up a wireless network, several family members can

    • ST Connectors

      ST Connectors

      The ST (Straight Tip) connector is a fiber optic connector which uses a plug and socket which is locked in place with a half-twist bayonet lock. The ST connector was the first defactor standard for fiber optic cabling. It was first developed by AT&T. ST connectors were leading connectors in the late 80s and early

    • FCAPS

      FCAPS

      FCAPS is an ITU standard model for enterprise management. The five FCAPS domains are: Fault Management Configuration Management Accounting Management Performance Management Security Management Fault Management Fault management is the domain where network problems are discovered and corrected. Steps are then taken to prevent them from occurring or recurring. By doing so, the network remains

    • Understanding Data Encapsulation

      Understanding Data Encapsulation

      The sending and receiving of data from a source device to the destination device is possible with the help of networking protocols when data encapsulation is used. The data is encapsulated with protocol information at each OSI reference model layer when a host transmits data to another device across a network. Each layer communicates with

    • What is Multicast Wireless?

      What is Multicast Wireless?

      Multicast is the transfer of messages to multiple destinations simultaneously, using fewer networks. The information is delivered to each of the links only once, and copies are created when the links to the destinations split, thus creating an optimal distribution path. Multicasting reduces unnecessary packet duplication. A wireless network utilizes radio communication, unlike wired networks,

    • DHCP Scope

      DHCP Scope

      A DHCP scope is a valid range of IP addresses that are available for assignment or lease to client computers on a particular subnet. In a DHCP server, a scope is configured to determine the address pool of IPs that the server can provide to DHCP clients. Scopes determine which IP addresses are provided to

    • What is a Smart Antenna?

      What is a Smart Antenna?

      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,
