Various Kinds of Computer Network Topology and Excess Drawback

1. Topology BUS

Bus Topology is a topology which is widely used in the future use of cables sepaksi mushroomed. By using T-Connector (with a 50 ohm terminator on the end of the network), then the computers or other network devices can be easily connected to each other.

Excess

    * Save cables
    * Layout is simple cable
    * Easily developed
Shortage

    * Detection and isolation of very small errors
    * Traffic Density
    * When one client is damaged, then the network can not function.
    * Required repeaters for long-distance
2. Topology RING

Token-ring method (often called a ring anyway) is how the computer so that the ring-shaped (circular). Each node has the same degree. Network will be referred to as a loop, the data is sent kesetiap node and each node examined information received address whether or not the data was for him.
Profit   * Save Cables
Loss

    * Sensitive error
    * Development of a network of more rigid

3. STAR Topology Definition

Centralized control, all links must pass through the center channel all the data node or client chooses. Stasium called primary central node or server and the other is called the secondary station or client server. Once the network connection initiated by the server, each client server at any time using a network connection without waiting for orders from the server. 
Pros:

    * Most flexible
    * Installation / change station is very easy and does not interfere with other parts of the network
    * Centralized control
    * Ease of detection and fault isolation / damage
    * Ease of network management
Disadvantages:

    * Boros cable
    * Need special handling
    * Centralized control (HUB) so the critical element

4. Understanding Topology Tree

Topology Tree (Tree) is a combination of characteristics between star topology and bus topology. This topology consists of a collection of star topology are connected in a bus topology as a backbone. Computers connected to the hub, while the other hub connecting the spine or backbone path.
Pros:

* Can the formation of a group is needed at all times. For example, companies can form a group consisting of terminal accounts, as well as in other groups formed for the sales terminal.
Disadvantages:

    * If the node is higher then does not work, then another group who are below it eventually becomes ineffective. The workings of a tree network is relatively slow.

5. Definition of Mesh Topology
 Mesh topology is a topology that was designed to have a level of restoration with various alternative routes or routing are usually prepared with the support of software or software.
Pros:

    * Relationship dedicated links to ensure the data is sent directly to the destination computer without having to go through other computers so as to more quickly because of the link is used exclusively for communicating with the destination computer only (not used beramai-ramai/sharing).
    * Have a Robust properties, ie the event of disruption in connection with a computer A computer B because of damage to the cable connections (links) between A and B, then the disorder will not affect the connection A computer with other computers.
    * Privacy and security in mesh topology is more secure, because the communication that occurs between the two computers can not be accessed by other computers.
    * Facilitate the identification of problems in the event of damage to connections between computers.
Disadvantages:     * Requires a lot of cable and port I / O. more and more computers in the mesh topology is needed more and more cable links and port I / O (see the formula for the need for cables and Port).
    * It is at once also indicate that the topology of this type * Because each computer must be connected directly to the other computer then the installation and configuration becomes more difficult.
    * The number of wires used also suggest the need to allow space in the room where the computers are located.

6. Topology Peer-to-Peer NetworkPeer meaning co-workers. Peer-to-peer network is a computer network that consists of multiple computers (usually no more than 10 computers with printers 1-2). In the preferred system of this network is the use of the program, data and printer together. Named Dona computer users can use the program installed on the computer Dino, and they both can print to the same printer at the same time. Network system can also be used at home. Computer users who have computers 'old-fashioned', such as AT, and wanted a new computer memberli, say Pentium II, no need to throw old computers. He simply install a second network card in the computer and then connected by a special cable used for networking systems. Compared with the three methods, the system is much simpler network that is easier to learn and use.
