Manufacturers, vendors, collaborators, customers, and other business relations can use an extranet, which is a section of the company's intranet that is available to persons outside the firm. Extranet access is required for everyday business work. Transactions with identify data, accounting and invoicing, payment-related processes, collaborative effort operations, item flyers for collaborators, discounted rate lists for partners, and other activities are just a few examples. 6

Network topologies

Network topology is network's physical and logical arrangement of nodes and connections in a network. Common node components include ports, router, and systems that may act as a router or switch. Graphs are used to depict network topologies regularly.

Bus network

A single cable connects every nodes in the bus topology in series. In today's fibre broadband distribution networks, this topology is prevalent. When the network is small, it works well since adding and deleting devices is easy, and it is less expensive than other topologies.

Star network

A central device links to all other nodes via a central hub in a star network configuration. In Ethernet-based switching local area networks, as well as most wired home and corporate networks, the physical star architecture is used. The star network is more trustworthy since each device is connected to the central core; it also makes issue identification easier. It, on the other hand, is too reliant on the main core and is hence more expensive.

Ring network

A ring network's networks are linked in a full round. Certain circles can only transmit data in one way, whereas others can transmit information in both sides. Bidirectional ring networks are more resilient than bus networks because traffic can reach a node in either direction. The ring network operates at a high speed. The speed of data transfer remains unaltered even when the network is under tremendous stress; nonetheless, a single damaged cable might cause the network to fail.
