      How to Reset a Netgear Router

      Netgear routers are some of the most popular routers in the world, providing both residential and commercial users with wireless networks that are accessible from a wide variety of mobile devices such as laptops, tablets, smartphones, and even desktop computers that are outfitted with a wireless adapter (which Netgear also sells). Netgear routers are available

    • PPP (Point-to-Point Protocol)

      PPP (Point-to-Point Protocol)

      PPP (Point-to-Point Protocol) is the most widely used method for transporting IP packets over a serial link between the user and the Internet Service Provider (ISP). Although PPP is primarily used over dialup lines, variants such as PPoE (PPP over Ethernet) and PPoA (PPP over ATM) extend PPP to new data-link layer protocols. PPP was

    • IP (Internet Protocol)

      IP (Internet Protocol)

      The primary network communications protocol used on networks today is the IP (Internet Protocol). IP relays or transfers network packets, also known as datagrams, to destinations on local networks or across the public Internet. It defines the structures which encapsulate information as well as the legal addressing methods used to identify the source and destination

    • 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

    • TCP/IP Ports

      TCP/IP Ports

      TCP and IP are two seperate protocols. IP (Internet Protocol) is a network layer protocol, while TCP (Transmission Control Protocol) is a transport layer protocol. Every computer and network device attached to the Internet has at least one IP address. For example, the IP address of this web server is Then, within each of

    • Multi Mode Fiber

      Multi Mode Fiber

      Multi-mode fiber is a type of fiber optic cable which is thick enough for light to follow several paths through the code. Multi-mode fiber is best suited for use in short lengths, such as those used in Local Area Networks (LANs) and Storage Area Networks (SANs). Multi-mode fiber comes in two standard widths, 62.5 micron

    • Bandwidth Monitor

      Bandwidth Monitor

      A bandwidth monitor is a computer application that is able to monitor the bandwidth of a particular network. Bandwidth monitors are able to keep track of the current network speed for both uploads and downloads, the amount of data transferred, the computer’s IP address, and the network card address. By observing the results of a

    • ADSL Router

      ADSL Router

      An ADSL router is also known as a DSL modem. The router connects the computer to the DSL phone line so the ADSL service can be used. Some countries also use the term NTBBA (Network Termination BroadBand Access). There are some ADSL routers that are also capable of sharing a single Internet connection with a

    • How to Clear the ARP Cache

      How to Clear the ARP Cache

      ARP (Address Resolution Protocol) Cache is a technique used to store “mappings” of  OSI Model Network Layer addresses (IP addresses) to corresponding OSI Model Data Link addresses (MAC addresses). Due to a variety of possible circumstances, ARP cache can become damaged requiring the end user or administrator to determine how to clear the ARP cache

    • Multilayer PCB

      Multilayer PCB

      A printed circuit board (PCB) is a thin board "printed" with electrical wires and made from fiber glass or similar material. PCBs are commonly used in computer devices such as motherboards, network interface cards, and RAM chips. They are relatively cheap and quite fast. When the PCB is fabricated with several layers placed over one
