Comparison between Networking Devices

Comparing Networking Devices
The Various networking Devices include hubs, switches, Repeaters and Routers. These devices operate at the diffrent layers of OSI Model. The bellow tables are showing the comparison between various devices

Hubs Vs Switches
Hubs	Switches
Transfers data to all the connected ports,	Transfers tho data to the port for which it is addressed
Operates at tho Physical layer in the OSI model.	Tho Switches operate at tho Data link Layer or sometimes at tho Network Layer in tho OSI model
Hubs are connected to the system via the half-duplex connection	Switches are connected to tho system via the full-duplex connection.
Less expensive than the Switches.	More expensive than the Hubs.
The number of ports in hubs is between 4 and 24.	The number of ports in Switches is between 4 and 48
Router Vs Bridge
Routers	Bridges
Routers use software-configured network address to determine the address.	Bridges determine thedestination address with tho help of the MAC address of the device.
Routers use the router tables to route the data to the destination.	Bridges do not use any device totransfer the data to the destination address.
Routers communicate with other routers to decide the best way to transfer the data.	With the help of MAC addresses of the devices, the Bridges listen to the network traffic and then decide the way to send the data.
Routers are used to connect the LAN and WAN links,	Bridges are used to connect the LAN links.
TCP/IP, AppleTalk, Internetwork Packet Exchange/ Sequenced Packet Exchange (IPX/SPX) are the routing protocols	Transparent bridge and Translational bridge are the types of Bridges.
Switches Vs Routers
Switches	Routers
The switches determine the destination address with the help of hardware-configured MAC address and transfer the data.	Routers use software-configured network address to determine the address.
Switches transfer the data between LAN segments.	Routers transfer the data between LAN and WAN segments
Switches operate at the Data Link Layer or sometimes at the Network Layer of the OSI model.	Routers operate at the Network Layer of the OSI
Switches cannot share or transfer data using an Internet Connection.	Routers are capable of sharing an internet connection.
Switches offer wired connectivity in the network.	Routers offer both wired and wireless connectivity in the network
Firewall Vs Routers
Firewall	Routers
Firewalls protect the data in the network from the intruders of Internet.	Routers route the data or packets in the network.
Firewalls operate at the Network and the Transport layer of the OSI model.	Routers operate at the Network Layer of the OSI model and in the gateway, the place where two or more networks meet.
Firewalls encrypt the data before transmission.	Routers do not encrypt the data before routing to the network.
Firewalls cannot share two networks, instead can protect the networks.	Routers are capable of sharing an internet connection between LANs and WANs.
