A hub can connect two or more devices on LAN via Ethernet. However, a switch can join multiple devices in one LAN. The hub uses a half-duplex mode to exchange the data. A switch uses a half/full-duplex mode.
Switches are more efficient than hubs, as they are better suited for connecting individual devices rather than connecting networks. It is designed to be an address-based connection, as they use the source and destination address for data transmission.
A network switch is a small hardware device that joins multiple computers together within one local area network (LAN). A Hub connects multiple Ethernet devices together, making them act as a single segment.
A switch transmits data from one device to another in form of frames while a router transmits data from one network to another in form of packets. A hub transmits data from one device to another in form of binary bits.
If you have the need for more connections, an Ethernet switch may be a better option over a hub. The reason is that there is less lag when you use the switch with multiple devices on a hub since received frames will only be directed to devices active on the network.

Hubs are at a disadvantage against switches in networking because hubs are unable to differentiate between the devices on the network. If one computer is trying to reach another on a hub-based network, the computer will send the message to every other computer on the network, consuming bandwidth for each transfer.
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. It records the addresses of the computers connected to it in a table.
Key Differences Between Hub and Switch
A hub operates on the OSI physical layer, whereas a switch operates on the OSI data link layer. The hub uses a half-duplex cable, whereas the switch uses a full-duplex cable. The switch is an active device, whereas the hub is a passive device.
With an Ethernet hub, you can connect multiple PCs to a single network and broadcast data signals to all the connected computers. An Ethernet hub doesn't require a MAC address as it is a simple and basic device that broadcasts the data signal to all the connected devices.
A Hub is a networking device that allows you to connect multiple PCs to a single network, whereas a Switch connects various devices together on a single computer network. A Hub operates on the physical layer, whereas Switch operates on the data link layer.
Switch is faster than Hub. They can provide 100 Mbps, 1 Gbps, 10 Gbps and 100 Gbps port speeds. Routers are almost equally fast as switches or, in some scenarios, faster than switches.
Ethernet switching connects wired devices such as computers, laptops, routers, servers, and printers to a local area network (LAN). Multiple Ethernet switch ports allow for faster connectivity and smoother access across many devices at once.
A hub has no processing capacity. It just copies over incoming data onto all of the other cables connected to it. This is OK for a small network and the device costs less than a switch. However, sensing all data out to all endpoints creates a lot of surplus traffic – switches are more efficient.
NO. Switches is switches, hubs is hubs. That means: Hubs are baiscally a multi-port repeater ....
While a network hub is cheaper, a switch is an effective device for dealing with complex Ethernet cables and networks.
A network hub is a node that broadcasts data to every computer or Ethernet-based device connected to it. A switch is a device that channels incoming data from any one of multiple input ports to the specific output port that will take it toward its intended destination.
Unmanaged switches usually have more ports than hubs and have a larger capacity to accommodate these ports. Different switches have different numbers of ports ranging from 4 to as many as 128 ports. On average, a switch is between 24 and 48 ports for wired connections. Hubs are smaller and featureless ports.
Essentially, a switch is a more efficient, more intelligent version of a hub. Perhaps the biggest difference between a hub and a switch is the way that it delivers data packets. Rather than blindly passing along data to all devices in a network, an industrial switch records the addresses of the connected devices.
A switch is preferred over a hub because a switch will only send message to device that needs or request it.
However, hubs have several significant disadvantages, including their limited bandwidth, which can result in slower network speeds and increased congestion. They cannot also differentiate between different types of network traffic, which can lead to security vulnerabilities.
There is no simultaneous transmission and receiving while using a hub. If, for example, two workstations connected to the same hub sent a message out at the same time, there would be a collision.
Hubs are therefore considered obsolete and switches are commonly used instead in modern LANs. Hubs have numerous disadvantages over switches, such as: they are not aware of the traffic that passes through them. they create only one large collision domain.
