      802.1Q

      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

    • MAC Address Filtering

      MAC Address Filtering

      MAC Address filtering is a technique that is implemented on many wireless networks to filter which devices are able to connect to the wireless network. MAC Address filtering allows an administrator to allow specific devices to connect to the network while blocking all other devices. MAC Address filtering is a free service provided by most

    • Broadband over Power Lines

      Broadband over Power Lines

      Broadband over Power Lines, or BPL, refers to the transmission (sending and receiving) of digital data through existing power cables and electricity distribution infrastructures. This can be viewed as a mere variation on using television cables; instead of using television cables, though, power transmission lines are going to be used. The Broadband over Power Lines

    • Tunneling

      Tunneling

      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

    • Broadcast Domain

      Broadcast Domain

      A broadcast domain is a logical part of a network (a network segment) in which any network equipment can transmit data directly to other equipment or device without going through a routing device (assuming the devices share the same subnet and use the same gateway; also, they must be in the same VLAN). A more

      How to Use Telnet

      Telnet is a utility program that allows remote access to other computers if they are installed on a network or have access to the Internet. Telnet lets users run commands on the remote computer. It can execute commands faster than the Web and other popular remote computer access applications. Telnet is not widely used as

    • Coaxial Cable

      Coaxial Cable

      Coaxial cable, also called coax, is used to transmit radio frequency (RF) signals. It has low emission losses and provides protection from electromagnetic interference, allowing signals with low power to be transmitted over longer distances. Coaxial cable is comprised of an inner core, insulator, shield, and outer cover. It is called coaxial because these sections
