      Subscriber Connectors (SCs)

      The Subscriber Connector (SC) is a fiber optic connector with a push-pull latching mechanism that provides quick insertion and removal while ensuring a positive connection. The SC is also available in a duplex configuration. It has a benefit in keyed duplex capability to support send/receive channels. This connector is commonly used for most modern network

      Understanding Data Encapsulation

      The sending and receiving of data from a source device to the destination device is possible with the help of networking protocols when data encapsulation is used. The data is encapsulated with protocol information at each OSI reference model layer when a host transmits data to another device across a network. Each layer communicates with

    • 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

    • 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

    • UDP (User Datagram Protocol)

      UDP (User Datagram Protocol)

      User Datagram Protocol or UDP is part of the Internet Protocol suite. By using UDP, programs running on different computers on a network can send short messages known as Datagrams to one another. UDP can be used in networks where TCP is traditionally implemented, but unlike TCP, it does not guarantee reliability or correct data

      Symmetric DSL

      Symmetric Digital Subscriber Line (SDSL) is a kind of one kind of Digital Subscriber Line (DSL) used to provide high-speed Internet connectivity. Symmetric DSL is called “symmetrical” because the upstream and downstream connections have the same bandwidth. SDSL maintains the same high speed in both directions while working over the existing “twisted-pair” cables that exist

      Cannot Find Server

      Using a internet browser is very commonplace nowadays. Unfortunately, a “cannot find server” error code may interrupt the user’s website visit. This is not only frustrating for Microsoft Internet Explorer users, but for Opera, Safari, Firefox, and other web browser users. Finding and fixing the cause of this error is very important, as web users

      How to Change a WEP Key

      A WEP (Wired Equivalent Privacy) key is a type of security algorithm for wireless devices that protects a computer from hackers and people who are trying to access someone else’s Internet connection. It consists of the numbers 0-9 and the letters A-F and can be 10, 26, or 58 characters long. For devices within the

      802.11b

      802.11b is the standard that is popularly used for high speed wireless networks. The standard is set by IEEE (Institute of Electrical and Electronics Engineers) and uses a 2.4 gigahertz radio frequency. There are several standards that are in use today for wireless communication from one computer device to another; however 802.11b is cost effective,
