      802.11a

      802.11a is one of the many standards used for high speed wireless networks, usually referred to as Wifi. This standard was created by the IEEE (Institute of Electrical and Electronics Engineers) in 1999 and uses several different frequencies including 5.15-5.35/5.47-5.725/5.725-5.875 GHz to send and receive data from one electronic or computer device to another. There

      VLAN (Virtual Local Area Network)

      VLAN (Virtual Local Area Network) is a logical local area network (or LAN) that extends beyond a single traditional LAN to a group of LAN segments, given specific configurations. Since a VLAN is a logical entity, its creation and configuration is done completely in software. How is a VLAN Identified? Since a VLAN is a

      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,

    • Rogue Wireless Access Point

      Rogue Wireless Access Point

      A Rogue Access Point is a Wi-Fi Access Point which is setup by an attacker for the purpose of sniffing wireless network traffic. 802.11 (Wi-Fi) utilizes SSIDs (Service Set IDentifiers) to authenticate NICs to wireless access points. There is no similar protocol for authenticating wireless access points. It is possible to place a rogue wireless

      How to Replace Your Wireless Router Antenna

      A wireless router is a computer networking device that routes data packets across another computer or across a wireless IP network. The wireless router comes with an 802.11 interface card and antenna. The wireless router antenna is generally what determines the signal strength of the wireless router. If your signal strength is weak, then you

      What Port Number is XXX on?

      The way that most services work under TCP/IP is that the server is configured to use a well known port number and the client connects from a random high port. Most of these well known ports are port numbers below 1,024. High ports are ports 1,024 or above. In the old days, ports below 1,024

    • 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

      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
