Star Topology


Star

A star topology is designed with each node (file server, workstations, and peripherals) connected directly to a central network hub, switch, or concentrator
Data on a star network passes through the hub, switch, or concentrator before continuing to its destination. The hub, switch, or concentrator manages and controls all functions of the network. It also acts as a repeater for the data flow. This configuration is common with twisted pair cable; however, it can also be used with coaxial cable or fiber optic cable.

Advantages of a Star Topology

  • Easy to install and wire.
  • No disruptions to the network when connecting or removing devices.
  • Easy to detect faults and to remove parts.

Disadvantages of a Star Topology

  • Requires more cable length than a linear topology.
  • If the hub, switch, or concentrator fails, nodes attached are disabled.
  • More expensive than linear bus topologies because of the cost of the hubs, etc.

Active and Passive FTP

Active and Passive FTP The FTP server may support Active or Passive connections, or both.  In an Active FTP connection, the client opens a port and listens and the server actively connects to it.  In a Passive FTP connection, the server opens a port and listens (passively) and the client connects to it.  You must grant Auto FTP Manager Access to the Internet and to choose the right type of FTP Connection Mode. Most FTP client programs select passive connection mode by default because server administrators prefer it as a safety measure.  Firewalls generally block connections that are "initiated" from the outside.  Using passive mode, the FTP client is "reaching out" to the server to make the connection.  The firewall will allow these outgoing connections, meaning that no special adjustments to firewall settings are required. If you are connecting to the FTP server using Active mode of connection you must set your firewa...
