What are 2 logical LAN topologies?
Local Area Networks The two logical topologies are broadcast (also known as bus) and sequential (also known as ring). In a broadcast topology, all devices on the network receive every message transmitted. Each device is responsible for recognizing messages meant for it.
What are the types of topology?
There are five types of topology in computer networks:
- Mesh Topology.
- Star Topology.
- Bus Topology.
- Ring Topology.
- Hybrid Topology.
What is logical and physical topology?
A logical topology is how devices appear connected to the user. A physical topology is how they are actually interconnected with wires and cables. However, its physical topology is a star, in which every node on the network connects to a central hub. See Ethernet and logical vs. physical.
What is the difference between physical and logical?
The fundamental difference between a physical address and the logical address is that logical address is generated by the CPU while the program is running whereas the physical address is a location in memory. The logical address is used as a reference to access the physical address.
Is MAC address physical or logical?
MAC Address is a physical address. IP Address is a logical address.
Is logical address same as IP address?
IP Address works at the network layer of OSI model (actually the IP layer of TCP/IP model). This is a logical address (and not the embedded hardware address) which is assigned by the Network administrator or Internet service provider. Hence IP address may change each time you connect with the Internet.
What is the difference between LAN and WAN?
A LAN (local area network) is a group of computers and network devices connected together, usually within the same building. A WAN connects several LANs, and may be limited to an enterprise (a corporation or an organization) or accessible to the public. The technology is high speed and relatively expensive.
Is Wan faster than LAN?
LAN is a computer network that covers a small geographic area, like a home, office, or group of buildings, while WAN is a computer network that covers a broader area. The speed of LAN is high whereas the speed of WAN is slower than LAN. LAN offers more fault tolerance but WAN offers less fault tolerance in WAN.
Is intranet LAN or WAN?
An intranet is a private network. Usually intranet is not used as a term for home networks, but technically every LAN is an intranet, or part of one. An intranet doesn’t have to be local, it can be the private network of a company with 3 offices which are all linked up with a Wide Area Network.
Can I connect LAN to WAN?
LAN to WAN – Connecting one of the main router’s ethernet port to the secondary router’s internet port. This connection makes it easier to identify which router the computers and other devices in the network are connected to since they will have different LAN IP segments.
What does LAN mean on router?
Local Area Network
Is LAN or WAN better for gaming?
WAN. LAN, which stands for local area network, and WAN, which stands for wide area network, are two types of networks that allow for interconnectivity between computers. LANs are typically faster and more secure than WANs, but WANs enable more widespread connectivity. …
Is LAN and WiFi the same?
WiFi is a wireless network to connect nearby devices to each other and share the internet via hotspots. Ethernet is a LAN network standard used in wired LAN. WiFi is based on IEEE 802.11x specifications where x is WiFi versions. Ethernet is wired and hence no mobility.
Which is faster WiFi or LAN?
A WiFi connection transmits data via wireless signals, while an Ethernet connection transmits data over cable. An Ethernet connection is generally faster than a WiFi connection and provides greater reliability and security. …
Does LAN need WiFi?
All that you need to do is run a network cable (LAN) to connect to the other PC. No internet connection is required. How do I connect a computer to a LAN? Using a Ethernet cable, you can connect computers a LAN via the router.
Why is a LAN used?
LANs are typically used in private households or in companies to set up home or corporate networks. This allows the various devices to communicate with each other. A LAN comprises at least two end devices, but it can also link several thousand devices to one another.
