Networking Basics: What You Need to Know

Here are some basics of networking. Networking helps to devices to connect to a computer, mobile 
phone, and even IOT devices, switch, router, and wireless access points are essential networking 
basics. Through these devices connected to your network can communicate with each other and with 
other networks like the Internet.

Networking Basics- Switches, routers, and wireless access points

Here in Chandigarh School of Networking, short-term computer courses in Chandigarh provide 
information about the performance of switches, router and wireless access points in every different 
aspects of the networking.

Switches: The switch is the foundation of most business networks. The switch acts as a controller and
connects computers, printers, and servers to buildings and campus networks.
With switches, devices connected on the network can communicate with each other and communicate 
with other networks to build a network of shared resources. With information sharing and resource 
allocation, the switch saves cost and increases productivity.
There are two basic types of switches, managed and unmanaged, as the basis of the network.

• The unmanaged switch can be used as it is, but it can not be set. Home network equipment usually
• provides unmanaged switches.
• You can set the management switch. Managed switches can be monitored and coordinated locally
• or remotely, giving you more control over network traffic and access.

Routers

A router connects multiple networks. Also, connect computers on these networks to the Internet. 
With routers, all networked computers can share a single Internet connection, thus reducing costs.
The router acts as a dispatcher. It Analyzes the data that are being transmitted over the network and 
also select the optimal route for transferring data, and send it halfway. Routers can connect business 
to the world, protect information from security threats, and even decide which computers take 
precedence over other computers. Besides these basics networking features, the router also has 
additional features to make networking easier and safer. Optionally, you can choose a router with a 
firewall, virtual private network.

(VPN), or Internet Protocol (IP) communication system.

Access points

With the access point, the device can connect to the wireless network without cables. The wireless 
network makes it easy to bring new devices online and provides flexible support for mobile workers. 
The access point acts like a network amplifier. While the router provides bandwidth, the access point 
extends its bandwidth, allowing the network to support many devices and make those devices 
accessible from the network farther.

However, the access point does more than just extend Wifi. It also provides useful data about devices 
on the network, provides proactive security, and can serve many other practical purposes. Access 
points support different IEEE standards. Each standard is an amendment ratified over time. This 
standard works with changes in frequency, transmission of different bandwidths, and support for 
different number of channels.

Wireless networking

To create a wireless networking, you can choose from four different deployments. Each  networking 
basics deployment has appropriate attributes for different solutions.

Cisco Mobility Express

Mobility Express is a simple, high performance wireless solution for small and medium enterprises. It 
has all of Cisco's advanced features preconfigured with Cisco best practices. By default, Wi-Fi can be 
easily deployed in a short time. Ideal for basic networking of SMEs.   

Centralized deployment

Centralized deployment, the most common type of wireless network system, was traditionally used on 
campuses where buildings and networks are in close proximity. This deployment will integrate 
wireless networks, ease upgrades, and facilitate advanced wireless functionality. The controller is 
based on on-premise and will be installed in a centrally managed location.   

Converged deployment

Small campus and branch offices have consistent wireless and wired connections in an integrated 
deployment. This deployment integrates wired and wireless into a single network device 
(access switch) and serves as both a switch and a wireless controller.

Cloud-based deployment

This system uses the cloud to manage the local network devices installed in different locations. The 
solution requires a Cisco Meraki cloud management device. This device fully visualizes the network 
through the dashboard.
