      Presentation Layer

      The presentation layer is one of seven layers of the OSI (Open Systems Interconnections) Model and is found between the application layer and the session layer. The presentation layer is commonly used for encryption and decryption as well as the conversion of file formats. The presentation layer is considered the last layer in which data

    • IPsec

      IPsec

      IPSec (IP Security) is a suite of protocols which was designed by Internet Engineering Task Force (IETF) to protect data by signing and encrypting data before it is transmitted over public networks. The IETF Request for Comments (RFCs) 2401-2409 defines the IPSec protocols with regard to security protocols, security associations and key management, and authentication

    • Physical Layer

      Physical Layer

      The Physical Layer is the lowest layer in the OSI (Open Systems Interconnection) Model of computer networking and is used to transfer electrical signals that represent data from one place to another. While the Physical Layer does not represent data itself, it does provide a means for that data to move. Essentially, the Physical Layer

    • 802.11a

      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

    • Routing Protocols

      Routing Protocols

      A routing protocol is the implementation of a routing algorithm in software or hardware. A routing protocol uses metrics to determine which path to utilize to transmit a packet across an internetwork. The metrics that routing protocols use include: Number of network layer devices along the path (hop count) Bandwidth Delay Load MTU Cost Routing

    • RG-6

      RG-6

      RG-6 cable is one of the more common types of coaxial cables used for commercial and household purposes. The term RG-6 is a generic label that can be used to describe a whole range of cable designs. In fact, all cable designs described under RG-6 may well differ from one another in center conductor composition,

    • Routing

      Routing

      Routing is the process of moving packets through an internetwork, such as the Internet. Routing actually consists of two separate, but related, tasks: Defining paths for the transmission of packets through an internetwork. Forwarding packets based upon the defined paths. Routing takes place in IP networks, based on IP routing tables and its entries. The

    • Range Extender

      Range Extender

      A range extender is a device that can be placed between two connection points in order to bounce a wireless signal from one device to another. Range extenders work great for large offices and factories that need high-speed Internet throughout the premises without running cables or purchasing satellite Internet. Range extenders can be used with

      How to Find a LinkSys Router IP

      Linksys is the home networking division of Cisco, Incorporated and has significant penetration in the U.S. home networking market. A common question that arises for consumers who are new to home or small business networking is determining how to find a Linksys router IP address on a new or legacy network. When shipped from the

    • Network Layer

      Network Layer

      The Network Layer is located at the 3rd position in the seven layer OSI model. It offers serviceable and practical ways of transmitting variable length data series from a source to a destination through one or more networks, while preserving the class of service and error handling tasks. The Network Layer is accountable for source
