      Power Line Networking

      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

    • 502 Proxy Error

      502 Proxy Error

      While surfing the Internet, if an end-user encounters a 502 proxy error, he or she will not be able to view the desired web page. The error message is commonly encountered when accessing websites through a proxy server. The problem is typically caused for one of two reasons: 1 – The Internet Security and Acceleration

    • RPC Server Unavailable

      RPC Server Unavailable

      An RPC (Remote Procedure Call) is a technique used in computer science that allows an application to contact a separate application or service within the same hard drive or on a remote location. While the application initiating the call is known as the “client,” the application or location that is being called is referred to

    • 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

    • Routing Tables

      Routing Tables

      A routing table is a grouping of information stored on a networked computer or network router that includes a list of routes to various network destinations. The data is normally stored in a database table and in more advanced configurations includes performance metrics associated with the routes stored in the table. Additional information stored in

    • Wireless Networks

      Wireless Networks

      Wireless networks are those computer networks that use electromagnetic waves instead of wires in order to carry signals over the various parts of the network. Wireless networks which run over other wireless networks often utilize the lower layer networks to provide security and encryption. Stand-alone wireless networks either provide their own security and encryption features

    • IPsec

      IPsec

      IPSec (IP Security) is a suite of protocols which was designed by Internet Engineering Task Force (IETF) to protect data by signing and encrypting data before it is transmitted over public networks. The IETF Request for Comments (RFCs) 2401-2409 defines the IPSec protocols with regard to security protocols, security associations and key management, and authentication

    • Network Routers

      Network Routers

      A network router is a network device with interfaces in multiple networks whose task is to copy packets from one network to another. Routers operate at Layer 3 of the OSI Model, the Network Layer. This is in contrast to switches, which operate at Layer 2 of the OSI Model, the Data-Link Layer. A network

    • 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

    • LAN Switching and Switch Types

      LAN Switching and Switch Types

      Switches represent the features and technologies that can be used to respond to the requirements in emerging network design. Some basic operations and technologies of switches are as follows: Fast Convergence: Switches stipulate that the network must adapt quickly to network topology changes. Deterministic Paths: Switches provide desirability of a given path to a destination for certain
