What exactly is a Hub?
Software Development Company In India defines a hub as a common connection point for connecting devices in a network. It serves as a single point of connection for all devices connected to a hub. There are multiple ports on the hub. When a packet arrives at one port, it may be seen by all network segments since it is replicated to the other ports. A network hub, unlike a network switch or router, has no routing tables or intelligence and is used to transfer information and broadcast all network data across all connections. Although most hubs can detect network issues or faults such as collisions, broadcasting all data to several ports might be a security concern and cause bottlenecks. In the past, network hubs were popular since they were less expensive than a switch or router. Switches are far less expensive than hubs these days, and they give a superior solution for any network. Furthermore, because it is a dumb device, a hub has no IP address.
Various types of Hub
The following are three different types of hubs:
- Passive Hub
- Active Hub
- Intelligent Hub
Passive Hub:
A passive hub is a device that connects cables together to form a physical network. It is capable of detecting flaws and malfunctioning hardware. Simply said, it takes a packet via a port and forwards it to all other ports. It comes with standard ports (10base-2 port and RJ-45) that may be used in your network. All local area network (LAN) devices are linked to this connection. In addition, advanced passive hubs contain AUI ports that, depending on the network configuration, are linked as the transceiver.
Active Hub:
When opposed to a passive hub, an active hub has a few more features. Software Development Company In India has the ability to track data delivered to linked devices. It plays a crucial function between linked devices by using storage technology to examine the data to be delivered and determine which packet to send first. When packets are being sent, it has the capacity to repair broken packets while simultaneously holding the direction of the remaining packets and distributing them. If a port receives a weak signal but it is still legible, the active hub reconstructs it into a stronger signal before forwarding it to other ports. If any connecting device in the network is down, it might increase the signal. As a result, it contributes to LAN service continuity.
Intelligent Hub:
It is a step above passive and active hubs in terms of intelligence. Software Development Company In India says that hubs are equipped with management software that aids in the analysis and resolution of network issues. Expansion of the firm into networking is advantageous; management may assign users who help to work more quickly and effectively share a common pool by utilizing intelligent hubs. It, on the other hand, provides superior performance for the local area network. Furthermore, any physical instrument that detects a problem is able to detect the problem quickly.
