Information and technology (IT) were first used by famous authors Harold J. Leavitt and Thomas L. Whisler in an article published ‘Haward Business Review’ in the year 1958. Earlier IT was used for storing data and describing the process of storing information. Later, by the course of time, it was used for computer networking and computing and then telephones and televisions.
Networking Topology is a part of the course module of IT students in which the majority of scholars face issues. Hence, they also get troubled in working on assignments based on it and look for someone who can offer the best IT assignment help. In this article, we will discuss what is network topology and its types
Network Topology is a systematic arrangement of networks or codes, usually switcher, router or software switch. These topologies are either logical or physical. The logical topology shows the nature of the path that signals follow from codes to codes. Whereas physical topology is a layout of nodes.
Various Physical Topologies AreIn bus network topology, every network device or computer is connected with each other in series through a single cable. It distributes data in one direction. It costs less as compared to the other network topologies and it requires the least cable too.
In this network topology, every network is linked through a central node. Every single node has a defined connection to the hub. These hubs act as a repeater for data flow. This type of topology can be used with optic fiber, coaxial cable, and twisted pair.
In this network topology, the nodes are linked in a closed-loop. It forms a ring-like structure as every device is linked to others, with the last computer connected to the first. Some rings pass data only in a single direction whereas some transmit data in both directions. Ring network topology is cheap to install and expand.
Tree network topology is known as the start of stars network topology. Star topologies are connected in a star configuration on their own in this type of topology. This network topology is also known as hierarchical topology. There must be at least three levels to the hierarchical topology and it is perfect where the workstations are kept in groups. It is an extension of star topology and bus topology and it is used in wide area networks (WAN).
This type of topology connects nodes with links so that there are various paths between some points of networks. Networks are called fully meshed every node and device are connected to each other and it is called partially meshed when some nodes have multiples connections with others. It is not flexible and fully connected.
Logical TopologyIt usually refers to the relationship between logical connections and nodes. It is a higher-level idea of network setup, in which nodes are connected to each other, as well as it deals with how data is transmitted through the networks. It includes any cloud or virtual resources.
