what is a difference between hub and switch devices

What Is HUB and SWITCH

HUB 

A hub is a physical layer networking device which is used to connect multiple devices in a network. They are generally used to connect computers in a LAN. A hub has many ports in it. A computer which intends to be connected to the network is plugged in to one of these ports.

• Physical 1 layer
• working on bit 0 , 1
• it use halfduplex
• broadcast 
• 10 to 100 mbps speed
• not record mac address
• hub has 4, 8, 16, 24 ports

SWITCH

A network switch is networking hardware that connects devices on a computer network by using packet switching to receive and forward data to the destination device. A network switch is a multiport network bridge that uses MAC addresses to forward data at the data link layer of the OSI model.

• Data link 2 layer
• Framework
• Fullduplex
• Unicast
• 100 Mbps to 1 Gbps , 10 Gb to 40 Gbps speed
• Record Mac Adrress
• Manageable and Non-Manageable switch
• 4, 8, 16, 24, 48 ports

Transmission Way

Half-duplex - send or receive data one time like : vocytocy 

Full-duplex  - send and receive data at a time like : mobile

Broadcast     - one device send data to all device which a connected in a network.

Unicast        - one to one send data

Multicast     - send data one to many device in same network

Simplex       - one device send data or one device receive data like : Radio
