Definition of network topology


Network topology is defined as the structure by which nodes and network connections are connected. We mean both networks a computer network or a biological network. In terms of computer network typology, it refers specifically to the logical or physical topology of the network, We will learn more about networking topology.

Network topology
There are many major types of network topology, which are divided into two parts: the first, the more exclusive, the second, the multi-species,
a. Linear topology of the network.
B. Topology of the network.
C. Network topology.
Dr.. Tree topology of the network.
LIN helps the flow of information between network nodes and the logical definition of a network. Both types of logical and physical networks may be identical in a network and not in another network.
An important example of both logical and physical networks is the three-letter abbreviation (LIN), which is responsible for connecting the compass to the rest of the network nodes and planning to make these connections in the same grid forms. The node in the LAN defines the physical physical nature of networks .
Physical topology speaks of the design of the network in terms of cables, their location and in terms of devices. The logical topology is concerned with how data travels from one place to another regardless of the image of the network.
Star topology is the easiest and simplest type of topology used in design and implementation. It is the most common among other types. It is easy to add new nodes to the grid, but it has disadvantages. Is an important form of network and may be repeated more than the central axis and nodes or other terminals where the repeater is used to increase the transmission distance between the central axis and the cluster.
In these types of topological networks, each computer is connected in a closed loop, and an organization is passed to allow the signal to be transmitted and transmitted across all computers connected in the same direction. It should be noted that the nodes also have certain marks, enabling devices to broadcast on the network and work with other computers As a tool to strengthen or duplicate the signal, and there are many examples of networks that use this type of topology and used to pass tags.
