    Interconnecting LANs

    Multivendor Interconnectivity
      Connecting different network operating systems needs to be handled in a planfull manner.

    Interconnectivity can be implemented from:

      the client
      the server

    This unit deals with Novell and NT interconnectivity.

    Client Based Solution

      Load multiple redirectors.
      If appropriate protocols are being used, loading both Novell and NT redirectors on a WIN 95 client establishes interoperability.

    Server Based Solution

      Gateway services
      Loading gateway services for Macintoshes onto an NT server effects intoperability.
      Automatically converts files to Mac format when they are retrieved from the server.
      Loading Gateway services for Novell on an NT network also effects interoperability.

    Microsoft Redirector

      Automatically recognizes Microsoft networks
      Included with NT, 95, and WfWG.
      Automatically installs during O/S installation.

    Macintosh Interoperability

      Services for Macintosh enable Microsoft clients and Apple Macintosh clients to share file, print, administrative, and other network resources.
      Supports LocalTalk, Ethernet, Token Ring, and FDDI.
      Included as part of NT Server.

    Novell Interoperability

      NT Workstation
      NWLink
        Client Service for NetWare (CSNW)
      NT Server
        NWLink
        Gateway Service for NetWare (GSNW).

    Novell Interoperability

      File and Printer Services for Netware (FPNW) enables Novell clients to access NT server file and print resources.
        Not included with NT server.

    Centralized Computing

      Mainframes/ 'dumb' terminals
      Character based
      Each application has a unique interface
      In many environments, being replaced by client/server

    Client/Server Environment

      Clients requests access to server resources
      Servers provide resources (programs, data, processing)
      The WWW is an example of a client/server arrangement.

    DBMS and Client/Server

      DBMS are prime client/server candidates.
      Client generates Structured Query Language (SQL) calls that translates what the user desires into a request that the database can understand.
      The application, or interface, is called the front end, the DBMS the back end.

    Client/Server Advantages

      Scalability
      Windows client interfaces
      Maintainability
      Security
