Base of computer networking
When we start to learn about computer networking, understanding how switches and routers work is the first step. Networks function, connecting computers with other devices such as switches and routers. Switches and routers make communication between connected devices on one network or different networks possible or. Routers and switches have different functions..
Base of networks: Switches
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, one aspect of your networking basics, 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 you money and increase productivity.
There are two basic types of switches to choose from as part of your networking basics: managed and unmanaged.

An unmanaged switch works out of the box and does not allow you to make changes. Home networking equipment typically includes unmanaged switches.

A managed switch can be accessed and programmed. This capability provides greater network flexibility because the switch can be monitored and adjusted locally or remotely. With a managed switch, you have control over network traffic and network access.

Network: Routers

Routers, the second valuable component of your networking basics, 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 route for your information to travel so that you receive it quickly.

Routers analyze the data being sent over a network, change how it is packaged, and send it to another network or to 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.

Depending on your business and your networking plans, you can choose from routers that include different capabilities. These can include networking basics such as:

  • Firewall: Specialized software that examines incoming data and protects your business network against attacks.
  • Virtual private network (VPN): A way to allow remote employees to safely access your network.
  • IP phone network: Combines your company’s computer and telephone network, using voice and conferencing technology, to simplify and unify your communications.
