      How to Use Ping to Test a Network

      The following steps elaborate on how to use the Ping utility to perform progressively more distant tests on network connectivity. Ping the Loopback Address – Type Ping 127.0.0.1 Successfully pinging the loopback address verifies that TCP/IP is both installed and configured correctly on the local client. If the loopback test fails, it means IP stack

    • What is EIGRP?

      What is EIGRP?

      Local and international networks require information to be constantly updated in order to properly route communications. Routing protocols were developed in order to help keep information flowing to the proper locations and to maintain network connectivity on both LAN and WAN. The Enhanced Interior Gateway Routing Protocol (EIGRP) is one of the most popular internal

    • Ethernet Splitter

      Ethernet Splitter

      An Ethernet splitter can split a single Internet connection so that two or more computers can connect to the Internet simultaneously. It can also create additional connections for other computers on a network, which can reduce the overall amount of cabling required to setup a network. Unfortunately, Ethernet splitters cannot resolve the network collision issues

    • ADSL Modems

      ADSL Modems

      Description of ADSL A special Internet service which is available in many areas is called the Asymmetrical Digital Subscriber Line (ADSL). ADSL connections use existing copper telephone lines to transmit data to and from the ISP. These connections may be limited by proximity to the ISP or the telephone company because the data will lose strength through

    • Cat 3

      Cat 3

      Cat 3, short for Category 3, is a UTP (Unshielded Twisted Pair) cable designed to carry voice and data up to 10 Mbps (mega bits per second), with possible transmission frequencies up to 16 MHz. Cat 3 cable is part of a family of copper cabling standards defined jointly by the Electronic Industries Alliance (EIA)

      Responding to Network Attacks and Security Incidents

      Network Attacks Review A network attack occurs when an attacker or hacker uses certain methods or technologies to maliciously attempt to compromise the security of a network. Hackers attack corporate networks to use data for financial gain or for industrial espionage, to illegally use user accounts and privileges, to run code to damage and corrupt

    • 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,

    • IP Address Conflict

      IP Address Conflict

      An IP (or Internet Protocol) address conflict occurs when two different systems on the same subnet are assigned or otherwise have their network interface configured to use the same IP address. It is possible to have two systems on different subnets configured with the same IP address, but not have a conflict occur due to

    • Static Route

      Static Route

      A static route is one that a network administrator creates manually. The opposite of a static route is a dynamic route. Dynamic routes are created by routing protocols. Static routes have advantages and disadvantages when compared to dynamic routes. Advantages of Static Routes: Easy to configure No routing protocol overhead Disadvantages of Static Routes: Network
