      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

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

      192.168.0.1 is a private IP address that is commonly used by Netgear and D-Link routers. The Netgear and D-Link brands are competitors to the Linksys division of Cisco, Incorporated and make a large number of the Internet routers used world-wide. The network address is not granted to the Netgear and D-Link companies exclusively; however, as

    • 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

    • Subnet Masks

      Subnet Masks

      A subnet mask allows users to identify which part of an IP address is reserved for the network and which part is available for host use. By looking at the IP address alone, especially now with classless inter-domain routing, users cannot tell which part of the address is which. Adding the subnet mask or netmask

      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

    • Collision Domain

      Collision Domain

      A computer network can be segmented physically and logically. A collision domain is one of the logical network segments in which the data packets can collide with each other. One of the most common protocols used when referring to a collision domain is the Ethernet protocol. Collision domains are often referred to as ‘Ethernet segments.’

    • Subnetting

      Subnetting

      Subnetting is the process of breaking down an IP network into smaller sub-networks called “subnets.” Each subnet is a non-physical description (or ID) for a physical sub-network (usually a switched network of host containing a single router in a multi-router network). In many cases, subnets are created to serve as physical or geographical separations similar

    • NAT (Network Address Translation)

      NAT (Network Address Translation)

      NAT (Network Address Translation) is a technique for preserving scarce Internet IP addresses. Why NAT? The current Internet uses IP addresses in the form xxx.xxx.xxx.xxx. A sample IP address might be 202.187.4.212. Because of the way these IP addresses are allocated, there started to be a shortage of available IP addresses. The current IP (Internet

    • Routing Software

      Routing Software

      Most networks currently run on hardware-based routers from vendors like Cisco, Foundry, and Juniper. Computing power has advanced to the point where this is not necessary. General purpose computing platforms can replace these expensive dedicated hardware routers. These software routing platforms usually run on some version of free or inexpensive Unix. These are a few

    • 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.
