      VDSL (Very High Bit-Rate Digital Subscriber Line)

      Broadband has revolutionized the way we view and use the internet. The two main types of broadband technology that have pervaded the market are Asymmetric Digital Subscriber Line (ADSL) and cable modems. Both these technologies are a huge leap from the days of the 56 Kbps dial-up connections, with maximum speeds ranging between 8 to

    • PPP Authentication Protocols

      PPP Authentication Protocols

      Windows Server 2003 and Windows XP support the following PPP authentication protocols: PAP or Password Authentication Protocol The oldest forms of authentication schemes used where the user credential are sent in plain text. This is not the securest form of passing authentication credentials as anybody can use a third party sniffer program and capture these

    • DSLAM (Digital Subscriber Line Access Multiplexer)

      DSLAM (Digital Subscriber Line Access Multiplexer)

      Faster connections to the Internet from phone lines are possible through a Digital Subscriber Line Access Multiplexer (abbreviated to DSLAM).  The role of this network device is located in the telephone exchanges of providers for the services.  The service works by taking advantage of the multiplexing techniques used to connect several Digital Subscriber Lines to

    • 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

    • DOCSIS (Data Over Cable Service Interface Specification)

      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

    • Ethernet Cable Pinout

      Ethernet Cable Pinout

      Ethernet cable connects a network interface card (NIC) with a hub or Ethernet switch. Ethernet cables can be purchased from a computer store. They come in two categories, flat and braided. The flat or solid cable is used when there is a need for a longer cable run. However, it is not flexible. Thus, its

    • Differences Between ISDN and DSL

      Differences Between ISDN and DSL

      Definitions Integrated Services Digital Network (ISDN): ISDN is a digital transmission system, which is used to transmit voice and data through copper telephone wires. In other words, it's a circuit-switched data transmission system that is used for voice and data transmission over the wire. Digital Subscriber Line (DSL): DSL is also a digital transmission system

    • How fast is ADSL Speed?

      How fast is ADSL Speed?

      ADSL (Asymmetric Digital Subscriber Line) options are available in many locations. The speeds will vary for the service in many ways depending on several factors. The reason why it is called an Asymmetric Digital Subscriber Line is simple, as the speed for downloads will be significantly faster than the upload speed. This is because consumer DSL services are

    • ARP (Address Resolution Protocol)

      ARP (Address Resolution Protocol)

      ARP is the Address Resolution Protocol. The ARP protocol maps addresses between the Data Link Layer and the Network Layer of the OSI Model. The Data Link layer of TCP/IP networks utilizes MAC addresses; the Network Layer of TCP/IP networks utilizes IP addresses. ARP and RARP The ARP protocol is used to map IP addresses

    • Ethernet Hub

      Ethernet Hub

      For any two devices to be connected, they need a common place, or a hub, as it is called in the computer world. It basically connects multiple computers together. Most of the hubs available in the market today support Ethernet standards. This is why they are called Ethernet hubs, and are most commonly used in
