The way an internetwork operates is to connect computers and peripherals using two equipment’s – Switches and Routers. These two let the devices connected to your internetwork talk with each other as well as talk to other networks.

Though they look quite similar, routers and switches perform very different functions in an internetwork:

• Switches are used to connect multiple devices on the same network within a building or campus. For example, a switch can connect your computers, printers and servers, creating a network of shared resources. The switch would serve as a controller, allowing the various devices to share information and talk to each other. Through information sharing and resource allocation, switches save money and increase productivity.
• Routers are used to connect multiple networks together. For example, you would use a router to connect your networked computers to the Internet and thereby share an Internet connection among many users. The router will act as a dispatcher, choosing the best and shortest route for your information to travel so that you receive it quickly. Routers analyze the data being sent over an internetwork, change how it is packaged and send it to another network or over a different type of network. They connect your business to the outside world, protect your information from security threats, and can even decide which computers get priority over others.

How Businesses Use Routing and Switching?

Routers and switches are the building blocks for all business communications from data to voice and video to wireless access. They can enhance a company’s bottom line by enabling your company to increase productivity, cut business costs, and improve security and customer services
