Computer network topology in telecommunication can also be interpreted as a way that can connect between telecommunication device and other device. So it can form a network.
The network will then relate to each other and form data communication. There are several types of network topology that is often widely used, ranging from bus topology, star topology, Ring topology, linear topology and many others.
Each of these types of network topology has the advantages and disadvantages of each. This time it will be discussed further on linear topology or Runtut topology. It is called a topological topology due to its sequential layout and includes a fairly common layout. Here's a further explanation of the linear notion of topology.
Understanding Linear Topology
This type of linear topology is actually an extension of the type of bus topology, of which the main cable inside the network must be connected with every point that is on the computer with T-Connector. As previously described, linear networking is a network topology that has a fairly common layout.
One main cable in the network will connect to each point of the computer (connection) which will then be connected with the T Connector connector and at the end should end with the Terminator. The connectors commonly used in linear topologies are the BNC (British Naval Connector) type.
Actually BNC is not a connector name, it is just the name of the cable used in this network. There are several types of connectors used in the linear topology, among others are:
- BNC cable connector, is used to be able to connect the network cable to the T connector.
- BNC Barrel connectors, used to be able to connect 2 BNC Cables
- BNC Barrel connectors, used to connect the network cable to the computer.
- BNC Terminator, used to mark the end or end of a network topology
For the installation of this linear topology is actually very easy and cheap. There are only about 5-7 computers in the network.
Characteristics of Liniear topology
The linear topology has several characteristics that distinguish it from other types of network topology, namely:
- Using a BNC connector and an RJ 58 cable
- This type of network topology is the development of bus topology type
Advantages of Linear Topologies
The use of linear topologies has several advantages, such as:
- Easy to setup and expand your computer network
- Very efficient cables, compared to other types of network topology, the length of cable needed in fewer linear topologies.
- The cost of construction is very cheap and efficient, because you only need a few cables. The maximum of computers in the network is about 5-7 pieces only.
- The layout is simple, so you don't need to be too complicated in installation
- Does not require central control (server), so all computers within the network can work without a central (server)
- Easy to develop
- The addition and reduction of terminals will not interfere with any ongoing operation
- Linear bus network is very heavily used in small network, so it will be very good for LAN network.
Lack of Linear topology
Not only the advantages, there are some shortcomings that you need to notice in the use of linear topology, among others are:
- Detection and isolation of errors occurring within the network will be very small.
- The traffic that is in the network connection cable is very dense and high, so it could cause a lemot or crash. So it will not be suitable to use for those of you who have a computerized network with quite dense traffic.
- The security of data transferred in the network is less secure.
- If there is an increase in the number of users, it will impact network speed decreases. Thus making the data transfer process can slow down.
- Requires repeater if used for remote transfer.
- The use of terminator is mandatory and must be precise, this is due to dispose of the signal requires proper termination
- There are limitations on the main cable length as well as the number of nodes that can be connected within the network.
- It depends heavily on the central cable, so when the main cable in the network is being problematic it will cause the entire network to malfunction.
- It is difficult to detect problems when they occur on a single computer.
Well that's a detailed explanation related to the notion of linear topology (linear topology) along with advantages and disadvantages of its use.
Of course in the selection of the right computer network and as needed there are several factors that you need to look at, namely security problems and the type of topology that you will use. Selecting the right network topology will build a good computer network and work as needed.
