A Network hub allows numerous PCs to be interconnected to a single network, while a Switch links diverse devices on a single network connection.
Hub
A Network hub that connects several computers to a single system of network. It is used to link LAN segments. Because a hub contains several ports, when a packet reaches, it is duplicated to multiple other ports. A hub serves as a central point of connectivity for network devices.Types of Hubs
Active Hub: An active hub is a type of hub that has its own source of power. Along with the network, it may cleanse, enhance, and transmit the signal. It functions as both a repeater and a provisioning hub. They are also used to link two or more local nodes. Passive Hub: This sort of hub receives electricity from the active hub as well as cables from nodes. Passive hubs just send signals into the network without cleansing or amplifying them. It cannot be used to bridge the gap between nodes.Hub’s characteristics include
- It is compatible with broadcasting and pooled resources
- It consists of one broadcast network segment and one collision phase
- Working at the OSI model’s physical layer
- A hub cannot be used to construct a virtual LAN
- Half-duplex transmission mode is supported
- A hub only has one broadcast domain
- The spanning tree protocol is not supported
- Packet collisions are more common within a hub
Important Networking Hub Applications:
The following are some of the most important networking hub applications:- Hubs are often used in companies to link people and things
- They’re used to set up a modest home system of networks
- It’s being used to monitor networks
- You can construct a device or peripherals that are accessible over the network
Switch
Networking connects devices on a computer device that links multiple technologies on a single computer network. It could also be used to various forms transferred via the network with the help of electronic data. Switches are commonly referred to as bridging devices since the process of connecting network segments is also known as bridging.Types of Switches
Manageable switche have a console interface and an IP address that may be allocated and controlled.Characteristics of switch
- It is a 2 layer device of the Data Link l
- It operates on a set bandwidth
- It keeps a MAC address database
- Allows you to set up a virtual LAN
- It functions as a multi-port bridge
- Typically, it has 24 to 48 ports
- Half-duplex and full-duplex versions are supported
Applications of Switches
Switches can be used for a variety of purposes, including:- A switch aids in the management of data flow across a network
- LANs of medium to big scale with a number of connected managed switches
- SOHO (Small Office. Home Office) applications make extensive use of switches. To access the multiple broadband providers, SOHO typically uses a single switch
Difference Between Hub and Switch
Hub
- A hub is a device that functions on the physical layer
- In a hub, there is just one collision domain
- Half-duplex transmission is used
- According to the OSI model, hubs are Layer 1 devices
- A central hub should be used to link a network of personal computers
Switch
- A switch is a device that acts at the data connection layer
- Different ports have their own collision domains
- The manner of transmission is Complete duplex
- Network switches enable you to operate at the OSI model’s Layer 2 level
- Allow for the connection of various devices and ports
Conclusion
We discussed HUB, Switches, the difference between Hub & Switches, and other related topics through the study material notes on the difference between Hub & Switches. A Network hub typically links several PCs to a single network segment, whereas a Switch connects numerous devices on a single computer network. A Hub works at the physical layer, whereas a Switch works at the data connection layer. Basis differences between HUB & Switch are:- Hubs use half-duplex cable. Full-duplex cables are used by the switch
- The switch is an active device, whereas the hub is a passive device
- The hub employs electrical signal orbiting, whereas the switch employs frame and packet switching
