What is the difference between topology and network architecture

It is the closes layer to the end users. In this Access Layer, Access Switches resides and uysers are connected to these switches. Another imporant and most used technolog in this layer is VLANs. With VLANs, different parts of the company is divided. Disdtribution Layer is the middle layer of 3 Tier Architecture.

This layer works as the bidge of Access Layer and Core Layer. It is the aggregation layer of all Access switches. Instead of Access layer switches, multilayer switches are used in Distribution layer.

Redundancy is used in this layer to overcome single point of failure. Multiple Multilayer switches are used as redundant in this layer. Distribution policies are also used in this layer.

In other words the key technology between first and second layers of 3 Tier Architecture is switching. Between Distributiona and Core Layer 3 is used. In other words, the key technology between second and third layers of 3 Tier Architecture is routing. Core layer is also known as Backbone Network. Core Backbone Layer conencts ditribution layer devices.

Routing protocols are used in this layer and the main duty of this layer is provifing routing between them and the distribution layer. Redundanct is also important fort his layer. So, redundant core devices are used to overcome single point of failure. Whereas protocols are the standards used by networks to permit communication between network-connected devices.

A network in which there are multiple network links between computers to provide multiple paths for data to travel is called a mesh network or topology. Mesh Topology. Star topology is the most commonly used network topology. Networking is to access the network via the internet or by any kind of connectivity that involves, or requires a connection to do so.

Network is the actual set up or topology of the computers. A topology is the physical configuration of a network. Irregular topology is a common topology of LAN, where the information is sent through random connections between computers.

Bus Network Topology. The conclusion of network topology is to ensure that the system is working as required. Topology refers to the physical wiring process in a network. Network topology is the arrangement of the various components that make up the structure of a computer network.

Network topology may be depicted in a physical or logical manner. The topology that is suitable for a P2P peer-peer network is the hub-and-spoke topology. Bus topology as many nodes are connected to single link. The function of topology is to answer the question "how is this network physically wired". The arrangement of computers on a network is called topology. It describes how the individual computers are connected to each other and to the network.

The star topology. A star topology is a type of mathematical topology. Mathematical topology is essentially geometry without concern for distance.

Essentially, it is the topological structure of a network and may be depicted physically or logically. Network Diagram :. A computer network diagram is a schematic depicting the nodes and connections amongst nodes in a computer network. Sign up to join this community. The best answers are voted up and rise to the top.

Logical network topology examples include twisted pair Ethernet, which is categorized as a logical bus topology, and token ring, which is categorized as a logical ring topology.

Physical network topology examples include star, mesh, tree, ring, point-to-point, circular, hybrid, and bus topology networks, each consisting of different configurations of nodes and links.

A network topology diagram helps visualize the communicating devices, which are modeled as nodes, and the connections between the devices, which are modeled as links between the nodes. There are several different logical and physical network topologies from which administrators can choose to build a secure, robust, and easily maintainable topology. The most popular configurations include:.

Multi-access network topology, also known as a non-broadcast multiple access network NBMA , consists of multiple linked hosts in which data is transferred directly from one computer to another single host across a switched fabric or over a virtual circuit.
