T-568A Straight-Through Ethernet Cable   The TIA/EIA 568-A standard which was ratified in 1995, was replaced by the TIA/EIA 568-B standard in 2002 and has been updated since. Both standards define the T-568A and T-568B pin-outs for using Unshielde...

Abstract The Windows Server 2008 Foundation Network Guide provides instructions on how to plan and deploy the core components required for a fully functioning network and a new Active Directory domain in a new forest. Using this guide, you can deploy computers configured with the following Windows server components: ·          The Active Directory Domain Services (AD DS) server role ·          The Domain Name System (DNS) server role ·          The Dynamic Host Configuration Protocol (DHCP) server role ·          The Network Policy Server (NPS) role service of the Network Policy and Access Services server role ·          The Windows Internet Name Service (WINS) feature ·          Transmission Control Protocol/Internet Protocol ver...

OSI Model ( O pen  S ystems  I nterconnection model) The International Standards Organization's OSI model serves as a standard template for describing a network protocol stack. The Protocol Stack Using TCP/IP as a model, the sending application hands data to the transport layer, which breaks it up into the packets required by the network. It stores the sequence number and other data in its header. The network layer adds source and destination data in its header, and the data link layer adds station data in its header. On the other side, the corresponding layer reads and processes the headers and discards them. Upper Layers Layers 7 through 4 comprise the upper layers of the OSI protocol stack. They are more geared to the type of application than the lower layers, which are designed to move packets, no matter what they contain, from one place to another. Application Layer 7 This top layer defines the language and syntax that p...
