What is the main difference between a hub and a switch?
Hub and Switch are both network connecting devices. Hub works at physical layer and is responsible to transmit the signal to port to respond where the signal was received whereas Switch enable connection setting and terminating based on need.
What is the difference between hub bridge and switch?
The key difference between hubs, switches and bridges is that hubs operate at Layer 1 of the OSI model, while bridges and switches work with MAC addresses at Layer 2. Hubs broadcast incoming traffic on all ports, whereas bridges and switches only route traffic towards their addressed destinations.
What is the difference between hub and a layer 2 switch?
A hub is a very simple device that does virtually no processing and simply forwards the packets it receives. It does not read or inspect the data contained in the packets. On the other hand, a layer 2 switch has the processing power to look at the packets to know the destination and the source.
What are the differences between switch and router?
Router and Switch are both network connecting devices. Router works at network layer and is responsibe to find the shortest path for a packet whereas Switch connects various devices in a network. Router connects devices across multiple networks.
Why is switch better than hub?
A switch is more intelligent than a hub. As a hub, a switch is the connection point for the computers (and other devices) in a network. However, a switch is more efficient at passing along traffic. ... If the destination address is not in the table, the switch sends the traffic to all the connected computers.
Why use a hub over a switch?
A switch can join multiple computers within one LAN, and a hub just connects multiple Ethernet devices together as a single segment. Switch is smarter than hub to determine the target of the forwarding data. Since switch has a higher performance, its cost will also become more expensive.
What layer is router?
A router works at Layer 3 of the OSI model – the Network Layer. This is the layer that the IP protocol works at.
Is hub a Layer 2 device?
Hubs are basically layer 1 devices without any intelligence and do not separate collision or broadcast domains. Switches are basically layer 2 (MAC addresses) with some intelligence and separate collision domains.
Should all hubs be replaced with switches?
With the introduction of switching hubs as a replacement for repeating hubs, network performance was enhanced by breaking up one collision domain into several collision domains. However, is it necessary for modern Ethernet networks to only incorporate switches? The answer is no.
What are the advantages of using a Layer 2 switch over a hub?
What are two advantages of Layer 2 Ethernet switches over hubs? (Choose two.)
- decreasing the number of collision domains.
- filtering frames based on MAC addresses.
- allowing simultaneous frame transmissions.
- increasing the size of broadcast domains.
- increasing the maximum length of UTP cabling between devices.
What layer is a switch?
A network switch is a device that operates at the Data Link layer of the OSI model—Layer 2.
Can a switch replace a hub?
Hubs are an OSI "layer one" device. Traffic entering one port is forwarded to all other ports. Each hub that is connected to another hub increases the size of the collision domain. ... Replace those hubs with a switch and the problem you described will vanish!
