Local area networks (LANs) commonly use several topologies, with the most prevalent being star, bus, and ring topologies. The star topology connects all devices to a central hub or switch, facilitating easier management and fault isolation. The bus topology involves a single central cable to which all network devices are connected, while the ring topology connects devices in a circular format, where data travels in one direction. Each topology has its advantages and disadvantages, influencing its selection based on network size and requirements.

What physical topology operates around a central network device for networks?
The physical topology that operates around a central network device is known as a star topology. In this configuration, all network devices are connected to a central hub, switch, or router, which facilitates communication between them. This design enhances reliability, as the failure of one connection does not affect the entire network, though the central device's failure can lead to network disruption. Star topology is commonly used in home and office networks due to its simplicity and ease of management.
What is difference between topology and protocol?
Network topology is the physical design of a LAN which resolves the conflict that occurs between computers on the network attempting to transmit at the same time. Whereas protocols are the standards used by networks to permit communication between network-connected devices. -s74
What is the 3 most used wide area network topology?
The three most commonly used wide area network (WAN) topologies are point-to-point, hub-and-spoke, and mesh. In a point-to-point topology, a direct connection is established between two locations, providing a simple and efficient link. The hub-and-spoke model connects multiple remote sites to a central hub, facilitating easier management and data flow. Mesh topology involves interconnecting multiple nodes directly, allowing for redundancy and resilience, as each node can communicate with multiple others.
Nodes transmitting when it is their turn?
You are thinking ring topology. Not used much today.
Which physical topology uses the same communications line is used to connect all nodes?
logical channel
Where bus topology used?
Bus topology is used on a LAN, or a Local Area Network. It is the cable to which the nodes connect, and it is also known as a backbone.
Where the ring topology is commonly used?
Ring topology is commonly used in local area networks (LANs), particularly in environments that require predictable performance, such as in schools and small businesses. It was historically prevalent in token ring networks, where data packets travel in a unidirectional or bidirectional manner around the ring, minimizing collisions. Although less common today due to the rise of star and mesh topologies, ring topology can still be found in certain industrial applications and metro area networks (MANs). Its structured layout allows for easier troubleshooting and management of network traffic.
What are the purposes of Local Area Networks?
The purpose of Local Area Networks (LAN) is to connect computers in the nearby area. This is often used in places such as schools, a laboratory or at home, for example.
Where do bus topology usually used?
Bus topology is commonly used in small networks or for temporary setups, such as in local area networks (LANs) where the cost of cabling needs to be minimized. It is often utilized in environments like office buildings, schools, and during events where quick and easy installation is required. However, due to its limitations in scalability and fault tolerance, it is less common in larger or more critical network infrastructures.
What device is used to junction between local area network and wide area networks?
A router.
What network topologies are most commonly used on today's networks?
star topology. Because they include a centralized connection point; can easily be moved, isolated, or interconnected with other networks; they are, therefore, scalable. For this reason, and because of their fault tolerance, the star topology has become the most popular layout used in contemporary LANs.
What is the differce between subnet and wide area network?
Subnets are designed for local area networks (LANS) that are used in an organization or building. Wide area networks cover larger areas and don't use subnets.
What is the most commonly used physical topology?
The most commonly used physical network topology is the star topology. This design features a central device, such as a switch or hub, to which all other devices are connected. It is widely used in modern Ethernet networks due to its simplicity and ease of troubleshooting.
What is lan design?
The process of planning a local area network, including (but not limited to), IP address space (# of hosts), media used, topology, etc.
How is a LAN used?
A LAN, as in Local Area Networks, is used to connect a group of computers together to share resources and exchange information.
What is difference between Ethernet and DSL?
Yes, those are two quite different technologies.Ethernet is used mainly within local area networks; DSL is used mainly to achieve an Internet connection, between a client and an ISP.Yes, those are two quite different technologies.Ethernet is used mainly within local area networks; DSL is used mainly to achieve an Internet connection, between a client and an ISP.Yes, those are two quite different technologies.Ethernet is used mainly within local area networks; DSL is used mainly to achieve an Internet connection, between a client and an ISP.Yes, those are two quite different technologies.Ethernet is used mainly within local area networks; DSL is used mainly to achieve an Internet connection, between a client and an ISP.
Repeaters are typically used on what type of networks?
Either a Bus topology or Wireless repeating, depends on how the question is stated...
