Learning Network Topology & Computer Network

Learning Network Topology & Computer Network - Hi friend blogger, meet me again ramli siburian, in Berbagi Bersama. here I will share my little knowledge about computer network topology. probably most people already know what network topology, but for those who do not know, I will share knowledge. for those who have been curious what is a topology, let us refer to the discussion below

    A. Introduction of Computer Network Topology

Computer Network Topology is a thing that explains the geometric relationship between the basic elements of the constituent network, namely:

-        Node

-        Link

-        Station

B. Types of Network Topology

The types of network topology is divided into several kinds, according to the data transmission medium. Topologo Computer Network is divided into 2, namely:
1. Topology physically
    Describe how the cable, computer, and location of all computer network components are.
2. Topology logically
    Explain how information or data flow and how computers can be connected in a computer networ

Computer network topology can be divided into 6 types, namely:

1. Topologi Bus

2. Topologi Ring

3. Topologi Star

4. Topologi Mesh

5. Topologi Hirarki

6. Topologi Linear

In each topology there are advantages and disadvantages. I will explain what are the advantages and disadvantages of computer topology

advantages and disadvantages of computer topology as follows:

1. Topologi Bus

This topology is a topology that is widely used in the use of coaxial cables mushroomed. By using a T-connector (Terminator 50 ohm) then the computer or other devices can be easily connected to each other.
In this topology is used single or central cable, where all workstions and servers are connected.

Characteristics of topology bus : 

1. Old technology, with single cable

2. Does not require active equipment

3. The influence of communication work between computers

4. At the end of the cable mounted 50 ohm connector

5. If the cable is disconnected, all connections are disconnected between computers

6. Difficult to troubleshoot if there is a problem on the network

Advantages and disadvantages of topology bus:

1. The addition of new workstations can be done easily without interrupting other workstations.

2. Layourt cable is simple because it has only single or central cable.

3. Density of traffic path data between computers.

4. Repeater required for long distance.

2. Topologi Ring 

This topology is a series of dots that connect each other two points, which then form a circular path like a ring (ring). In the ring topology, each point / node serves as a repeater that will amplify signals along its circulation, meaning that each device works together to form this finger.

Characteristics of topology ring:

1. Each station in the network topology is a repeater capable of performing 3 functions, namely data 

    insertion, data reception, and data transfer.

2. This topology works almost the same as the concentrator as a central assembly of cable ends for 

     each connected computer.

Advantages and disadvantages of topology ring:

1. Easy to design and implement

2. It has better performance than bus topology, even for large data streams

3. Pelka to error, so that if there is a station problematic, then the network will be disrupted all

    stations

4. Can occur collssion (two data packet mixed)

3. Topologi Star

This topology is a form of network topology in the form of convergence center to every station point. This topology includes the network topology with the middle medium. This topology network is quite difficult to install. Each computer has its own cable making it easy to find errors in the network.

Characteristics of topology star

1. Damage to one station has no effect on the other

2. High security level

3. Most flexible

4. If the central terminal is damaged, the entire station can not communicate

5. Wasted in the use of network cables

6. The network depends on the central terminal

Advantages and disadvantages of topology star:

1. wasteful of wires

2. Need special handling for network management

3.Centralized control (hub) becomes a very important element

4. Topologi Mesh

Topology Mesh is a form of relationship between devices where each device is connected directly to other devices that exist in the network.
As a result, in mesh topology each device can communicate directly with the dedicated device (dedicated links).

Characteristics of topology mesh:
1. The device communicates directly with the other dedicated device.
2. There is no initial planning when building a topology.
3. Very similar to the computer network berpasiskan function that is peer to peer.


Advantages and disadvantages of topology mesh:
1. Relationship dedicated link ensures the data directly sent to the destination station
2. Privacy and security on mesh topology more secure
3. Requires cable and port1 / 0
4. The number of cables used also requires the need for space that allows in the room where the 
    computers are located

5. Topologi Hierarchy

The hierarchical / tree topology (tree) is a karasteristic combination between star topology and bus topology. This topology consists of a collection of star topologies that are connected in a bus topology as a backbone or baackbone path.
Computers are connected to hubs, while other hubs are connected as backbone paths.

Characteristics of topology hierarchy:
1. This topology is a combination of star topology and bus topology
2. It has a rather complex design in its use
3. It has a cable center but has also a central terminal for use by the station
4. The development of this topology is wider


Advantages and disadvantages of topology hierarchy:
1. Centralized data, in a hierarchy so that becomes better and easier data management.
2. Controlled, easily developed into a wider network
3. The disadvantage, if the knot, or the central cable cable is lost, then the existing sub-network, will
    work ineffectively
4. The way the network works is relatively slower

6. Topologi Linear

Topology Linear (coherent) is usually called the sued bus topology, this layout includes a general layout. One main cable connects each connection point (computer) connected to a connector called a T connection and at the end must end with a terminator.

Characteristics of topology linear:

1. BNC cable connection is used to connect the T connecting cable

2. Pentabung T-BNC is used to connect cable to computer

3. BNC tube container is used to connect 2 BNC cables

4. The BNC terminator is used to mark the end of the bus topology

Advantages and disadvantages of topology linear:

1. Save cable

2. The layout is simple

3. Do not need central control

4. Disadvantages, detection and isolation of minor errors

5. High traffic data density

6. Data security is not guaranteed

7. Speed will decrease when the number of users increases
