The Foundations of networking: CCNA 200-301 Day-1


SwitchesRouters, and wireless access points (APs) are essential in our networking. Through them, the devices connected to your network can communicate with one another and with other networks, like the Internet.

Switches, Routers, and wireless access points (APs) perform different functions in a network.

Switches

Switches are the main foundation of most business networks. A switch acts as a controller, connecting computers, printers, and servers to a network in a building or campus networking.

Switches allow devices on your network to communicate with each other devices, as well as with other networks, creating a network of shared resources. Through information sharing and proper resource allocation, switches save money and increase productivity.
There are two types of switches for your networking.

1. on-premises 
2. cloud-managed.
  1. managed on-premises switch when you configure and monitor your LAN, giving you control of your network traffic.
  2. cloud-managed switch can simplify your network management. You get an easy user interface,  full-stack management, and automatic updates delivered directly to the switch.
Routers:

Routers used to connect multiple networks together. Routers enable all networking computers to share a single Internet connection, which saves money. 
 It analyzes data which sent across a network and chooses the best route for data to travel and sends it on its way. 
Routers connect you to the world, protect information from security threats, and can even decide which computers receive priority over others. 
Routers come with more features to make networking easier and more secure. Depending on your security requirements, for example, a virtual private network (VPN), or an Internet Protocol (IP) communications system.

Access Points:

An access point* allows devices to connect to your network without cables. A wireless network use to bring new devices online and provides flexible support to mobile workers.

An access point acts as an amplifier for your network. An access point extends the bandwidth so that the network can support many devices,
The access point supports different IEEE standards. The standards operate on different frequencies, deliver different bandwidth, and support different numbers of channels.

Wireless Networking

There are three types of deployment in wireless.

1.     centralized deployment,
2.     converged deployment,
3.      cloud-based deployment.

      1. Centralized deployment

     The centralized deployments are traditionally used in campuses where buildings and networks are in close proximity/Area. The centralized deployments consolidate the wireless network, which makes upgrades easier and facilitates advanced wireless functionality. 

Note: For this deployment, Controllers need to be on-premises and are installed in a centralized location.  

2. Converged deployment
Its use in small campuses or branch offices, the converged deployments offer consistency in wireless and wired connections simultaneously. This deployment, we use an access switch to performs the dual role (wired and Wireless) of both switch and wireless controller.
3. Cloud-based deployment
The Cloud-based deployment system uses the cloud to manage network devices deployed on-premises at different locations. This solution requires Cisco Meraki cloud-managed devices, which provide full visibility of the network and remote configuration management through their dashboards.
