What are the LAN topologies and architectures?
What are the LAN topologies and architectures?
Topologies commonly are represented as network diagrams. A LAN architecture is built around a topology. A LAN architecture comprises all the components that make up the structure of a communications system. These components include the hardware, software, protocols, and sequence of operations.
What are four LAN architectures?
Network Architecture Overview
| LAN Architecture Summary | ||
|---|---|---|
| Network Type | Speed | Transmission Types |
| Token-Ring | 4/16/100 Mb/s | UTP, Type 1 STP, and fiber-optic |
| ARCnet | 2.5 Mb/s | RG-62 coax UTP, Type 1 STP |
| UTP = unshielded twisted pair, STP = shielded twisted pair, RF = Radio Frequency |
What is LAN architecture?
LAN architecture is the set of rules and design principles that define the LAN. A LAN is made up of three components: physical media, such as the cabling and network interfaces; the topology, such as a star or ring topology; and the protocols, or LAN technologies, such as Token Ring or Ethernet.
What is network topology architecture?
Network architecture refers to the overall design of a computer network, while network topology is more limited and refers to the arrangement of elements (i.e., links and nodes).
What are the three most common LAN architectures?
Table 8-2 lists the three most common LAN architectures….Describe LAN Architectures.
| Ethernet | Bus | |
|---|---|---|
| Token Ring | Star | Ring |
| Fiber Distributed Data Interface (FDDI) | Double ring | Ring |
What are the commonly used LAN architectures?
Four common LAN topologies exist: bus, ring, star, and tree. These topologies are logical architectures, but the actual devices need not be physically organized in these configurations.
Which topologies are used in LAN?
There are three common topologies found in LANs: star, ring, and bus. In a star topology, all devices on the LAN are interconnected through some central device.
What is the difference between network and topology?
It is the schematic description of a network arrangement, connecting various nodes (sender and receiver) through lines of connection. Physical topology confirms the physical layout of the connected devices and nodes, while the logical topology focuses on the pattern of data transfer between network nodes.
What is the purpose of network topologies?
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.
Is LAN A network architecture?
Local area network architecture is categorized as either peer-to-peer or client-server. On a client-server local area network, multiple client-devices are connected to a central server, in which application access, device access, file storage, and network traffic are managed.
What are the LAN topologies explain?
LAN physical topology defines the geographical arrangement of networking devices. Topologies are driven fundamentally by two network connection types: A point-to-point connection is a direct link between two devices. For example, when you attach your computer to a printer, you have created a point-to-point link.
What are different topologies used in LAN and WAN?
They include the following: The bus topology, which is characterized by the hard cabling in which the different sites on the network are connected by high capacity network cabling. The ring topology, which has sites arranged in a ring. The star topology, which has the sites arranged in a star formation.
What type of logical topology does a wireless LAN use?
Wireless networks have different topologies, just as wired networks do. However, wireless networks use only two logical topologies: Star -The star topology, used by Wi-Fi/IEEE 802.11-based products in the infrastructure mode, resembles the topology used by 10BASE-T and faster versions of Ethernet that use a switch (or hub).
Which topology is expensive?
In Mesh Topology , all the computers are inter-connected to each other in a network. Each computer not only sends its own signals but also relays data from other computers. This type of topology is very expensive as Its very difficult to establish the connections of the mesh topology.
Which topology is best in network?
A mesh topology is the best choice when you require fault tolerance, however, it is very difficult to setup and maintain. There are two types of mesh network: full mesh and partial mesh. A full mesh is one which every workstation is connected to the other ones in the network.
What is the best type of topology?
The best topology is ring topology. Star is the next best after ringr, and then bus, which is pretty old, but not too expensive. Full mesh topology is theoretically the best since every device is. connected to every other device, thus maximizing speed and security.
