      IP Address Classes

      IP Address classes were the original organizational structure for IP addresses. The specific address class would determine the maximum potential size for a computer network. The address class would define which of the specific bits of the address would be used to identify the network and network identification, the bits to identify the host computer

    • Frame vs Packet

      Frame vs Packet

      A packet and a frame are both packages of data moving through a network. A packet exists at Layer 3 of the OSI Model, whereas a frame exists at Layer 2 of the OSI Model. Layer 2 is the Data Link Layer. The best known Data Link Layer protocol is Ethernet. Layer 3 is the

    • 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

    • What is NetBEUI?

      What is NetBEUI?

      NetBEUI (NetBIOS Extended User Interface) is an extended version of NetBIOS, the primary software that allows individual computers to communicate within a given local area network. While NetBIOS itself is most often used to transfer pictures, documents, videos, or other files from one computer to another, NetBEUI is responsible for arranging the actual information in

    • traceroute

      traceroute

      traceroute is a command which is used to trace the route of a packet through a TCP/IP network. traceroute is a Unix command. Under Microsoft Windows, the traceroute command has been renamed `tracert`. Unix `traceroute` and Microsoft Windows `tracert` are designed to accomplish the same task, but differ in the way they display output, in

    • What is a Zeroconf?

      What is a Zeroconf?

      Zeroconf (zero configuration networking) refers to several protocols and techniques that are used together to create an IP (Internet Protocol) network with no special configuration servers or manual operator intervention. These networks allow novices to connect computers, network devices, scanners, and printers to create a functioning network without requiring manual configuration. Zeroconf does not require

      192.168.2.1 – What Are its Uses and Why is it Important?

      192.168.2.1 is a private IP address commonly used by the SMC and Belkin router manufacturers for device setup and troubleshooting. SMC and Belkin specialize in manufacturing home networking equipment that competes with Netgear, D-Link, and Linksys brands in the marketplace. The Internet Assigned Numbers Authority (IANA) does not grant exclusive use of the IP address

      QoS (Quality of Service)

      QoS stands for Quality of Service. QoS is a generic name for a set of algorithms which attempt to provide different levels of quality to different types of network traffic. Queuing One method of implementing QoS is to utilize some sort of advanced queuing algorithm. Simple networks process traffic with a FIFO (First In –

    • IP Address

      IP Address

      An IP (Internet Protocol) address is a unique address that different computers on a computer network use to identify and communicate with one another. An IP address is used as an identifier to find electronic devices connected to one another on a network. Therefore, each device in the network must have its own unique address.

    • VRRP (Virtual Router Redundancy Protocol)

      VRRP (Virtual Router Redundancy Protocol)

      VRRP stands for Virtual Router Redundancy Protocol. The VRRP is a commonly used method to avoid network outages during important data transfers. Data transfer can be highly susceptible to failure when sent by a single router network. To combat this problem, VRRP creates a virtual connection between routers within the same network and ties them
