Switch vs Hub

Hubs and switch are devices that let you connect one or more computers to other computers, networked devices, or even other networks. Each has two or more ports into which you plug in the cables to make the connection. There are some differences between switch vs hub. I often see the terms misused, so let’s clarify what each one really means so in this article I just make the comparison of both switch vs hub.

Comparison between switch vs hub

Device/function Hub Switch
Layer Physical Layer (Layer 1) -Hubs are classified as Physical layer (Layer 1) device of the Open system interconnected (OSI) model. Data Link layer (layer2) and some switches working in layer 3 which is called multilayer switch
Function Mostly used for personal computer network – To connect a network of personal computers together, they can be connected through a central hub. Multiple devices can be connect
Port can be managed
VLAN Can Create
On each port security can apply
Data Transmission form Bits or Electrical Signals   Frame (L2 Switch)
 Frame & Packet (L3 switch)
Ports 4 Ports
8 Ports
12 Ports
5 Ports
8 Ports
16 Ports
24 Ports
48 ports
Modular Switch
Soft Switch
Transmission Type Always performs data flooding to all ports,  may be unicast, multicast or broadcast First-time broadcast, then multicast and unicast as needed.
Device Type Passive Device (Without Software) Active Device (With Software) & Networking device
Used in   LAN LAN, MAN, WAN
Table Can’t learn or store MAC address. Learn and store mac address on its mac table
Transmission Mode Half duplex Half Duplex and Full Duplex
Broadcast Domain Hub has single Broadcast Domain and single collision domain Switch has single broadcast domain unless creating VLANs
And each port of a switch is collision domain
Spanning-Tree No Spanning-Tree Many Spanning-tree Possible in the switch
Speed 10Mbps 10/100/1000 Mbps
The address used for data transmission Uses MAC address Uses MAC address
