Ring technology:
In a ring network, every device has exactly two neighboring devices for communication purpose. It is called a ring topology as its formation is like a ring. In this topology, every computer is connected to another computer. Here, the last node is combined with a first one.
This topology uses token to pass the information from one computer to another. In this topology, all the messages travel through a ring in the same direction.

A B-to-B network is known as a extranet. It connects one business to another via a direct line. This allows a confidential network to be established for internal communication.
The hardware is usually connected by cat5 or cat6 cables. The wall sockets that they are usually plugged into run to a switch or switches that enable them to connect via more cables to the patch panel where the servers are also connected. each item would have its own static IP address(or in some cases they would use DHCP to assign them) so it could be found on the lan. IP addresses allow the switches and routers to direct the input from the computers to the proper machine.
The Network layer is where the frames of the Data Link layer become packets. The best way to think of the Network layer is as the mailroom clerk of the OSI model. The clerk receives mail and directs it to the appropriate couriers. In similar fashion, the Network layer translates the frames it receives from the Data Link layer into more logical packets which can be routed to other networks (like sending it to a courier). At the Network layer, you can begin to actually communicate across a Network, but the service is called "unreliable" because no connection can be established. Communication over the Network layer is something like throwing a message in a bottle into the sea - you cannot verify that the other person ever reads the message. It should be noted that most of what we call "routing" occurs at the network layer - that is, network traffic is routed from one network to another at this layer, allowing for inter-network (as opposed to intra-network) communication.
Its not a Router.. they only manage traffic on the network. Servers are specialized COMPUTERS that manage network resources and ALLOW computers access to the network.. BINGO! Sounds like you are talking about a "Router". A router manages and direct traffic on your local network. Routers make your connection faster and easier. It also makes your local network more secure!
Star topolohy.
Also called signal topology. Every LAN has a topology, or the way that the devices on a network are arranged and how they communicate with each other. The way that the workstations are connected to the network through the actual cables that transmit data -- the physical structure of the network -- is called the physical topology. The logical topology, in contrast, is the way that the signals act on the network media, or the way that the data passes through the network from one device to the next without regard to the physical interconnection of the devices. Logical topologies are bound to the network protocols that direct how the data moves across a network. The Ethernet protocol is a common logical bus topology protocol. LocalTalk is a common logical bus or star topology protocol. IBM's Token Ring is a common logical ring topology protocol. A network's logical topology is not necessarily the same as its physical topology. For example, twisted pair Ethernet is a logical bus topology in a physical star topology layout. While IBM's Token Ring is a logical ring topology, it is physically set up in a star topology.
A mesh topology is where each node or computer has a direct link to every other node that it needs to talk to. This topology is okay for small computer set ups (e.g. upto 6 computers) that need very high speed communication between them.Its not really used any more because it all gets a bit meshy...

The history of network topologies dates back to 1969-1970. This what when Roberts, who is now known as Dr. Howard, started researching on network topologies and founded Network Analysis Corporation.
A direct current is obtained from a connection to a battery.
With the rectifier alone, the result is d.c. but with a voltage ripple caused by the rectifier diodes not being absolute in action. The rectifier needs following with a smoothing circuit, a suitable capacitor at its simplest, to remove the ripple.
Some routers support direct connection with external storage, printers and so on. It depends on the model. You need to check your router's manual.
Direct Current
A star is a central 'hub' to which 'satellite' locations are connected. There is no direct communication between two satellites except through the hub.

For a direct network connection between two devices you need a cross-over cable.
