Switch vs Router

Difference/Comparison between Switch and Router:

SWITCH	ROUTER
It is a networking device	It is inter-networking device
It is used to connect End devices such as computers, printers, scanners etc.	Router is used to connect two or more different Networks
Network switches operate at layer two (Data Link Layer) of the OSI model.	Routers operate at Layer 3 (Network) of the OSI model.
It Transmits data in the form of Frame (L2 Switch) & Packet (L3 switch)	It Transmits data in the form of packets.
It makes use of MAC address for the purpose of data transmission.	It makes use of IP address for the purpose of data transmission.
Switches are available with different Ports i.e – 4, 8, 16, 24, 28,48 and 52.	Routers contain 2 Ports by default like fast Ethernet Ports. However, we can add serial ports explicitly.
It makes use of MAC table or forwarding Table	It makes use of the Routing Table for routes to get to the destination IP.
It is used for LAN networks.	It is used for LAN, MAN, WAN networks.
Switches are used in half as well as full duplex mode. However, we can also make them in auto-negotiation.	By default, Router is in full duplex mode. However, we can change them manually into half-duplex.
In Switches, we can neither perform Network Address Translation nor Port Address Translation.	In Routers, we can perform Network Address Translation as well as Port Address Translation

Switches are restricted to wired network connections.	Routers can work within both wired and wireless network situations.
