Router Vs Switch

Router and switch, both are computer connecting devices which allows one or more computers to connect to many other network devices, transmitting packets in dissimilar methods.

What is a Router?

Router, a virtual or physical layer 3 networking device that forwards information between two or more computer networks and it accomplish the traffic guiding operations on the Internet. Routers identify whether the destination and source are on a similar network or whether data need to be transported from one type of network to the other.

What is a Switch?

Switches are frequently used in huge networks like large scale business and school atmospheres. A switch is to connect numerous computers together in a solo local network. Multiple switches are available in a large network connecting various computer system groups together. Naturally, these switches are associated with a router permitting the allied devices to obtain Internet access.

Topic

Router

Switch

Explanation

A router is a virtual or physical networking device creating a connection between a local network to various other networks.

A switch is a networking device utilized to connect various devices collectively on a computer network.

Functionality

Router passes the data between various computers and the modem.

Switch enables connections to numerous devices like computers, printers, scanners etc, manage VLAN security configurations and handle ports.

Ports

Number of Ports: 2 by default. Serial ports can be added overtly.

A switch is a multi-port Bridge and accessible with different ports: 8/16/24/48/64

Network

Routing table is used to store the IP address and uphold address on its own.

Switches utilize the CAM (Content Accessible Memory) table that is naturally retrieved by Application Specific integrated chips (ASIC)

Usage of Table

Routing table is used to store the IP address and uphold address on its own

Switches utilize the CAM (Content Accessible Memory) table that is naturally retrieved by Application Specific integrated chips (ASIC)

Types

Full Duplex

Half/ Full Duplex

Broadcast Domain

Every port of router has its own broadcast domain

One (1) broadcast domain in Switch

IP Address

Router is using an IP address for data transmission

Switched are using MAC address for data transmission

Security

Router afford security procedures to defend the network

Switched has Port security

Connections

Router is used to connect two or more networks

Switch is used to connect two or more nodes in a similar or dissimilar network.

Speed

Speed range of a router is 1100 Mbps, if wireless and 100 Mbps to 1 Gbps if wired

Speed range of a switch is 10/100 Mbps and 1 Gbps

Data Transmission System

Data transmission in the router is through Packets

Data transmission in Switch is through Frames

Layer

Router is operated on a Network Layer

Switch is operated on a Data Link Layer. Network switches are operated at OSI model Layer 2

Device Connection

Router can connect to numerous networking devices or computers through WiFi or  Ethernet

Switch can connect to numerous networking devices or computers through Cat5e and Cat5

Decision on Routing

Routers routing decisions are very quick

Switches consume much time for routing decisions if the scenario is more complicated

Performance on Network Address Translation

Routers can perform Network Address Translation

Switches cannot perform Port Address Translation or Network Address Translation

Examples

Examples of Routers: Linksys WRT54GL Juniper MX & EX series Cisco 3900, 2900, 1900

Examples of Switches: Alcatel’s OmniSwitch 9000; Cisco Catalyst switch 4500 and 6500

Manufacturers

Cisco, Asus, Linksys, TP-Link, D-Link, Netgear

D-link Juniper and Cisco
