Hello everyone, this class is based on a very important topic of Networking & IT industry, if you are related to technical field, even you are a student or working as a professional then you need to be very clear with Networking Devices. In this class we will Learn about Network Devices like Switches and Routers .we are also going to discuss about Firewall, Modem, Gateway, repeaters Moreover, in another video class wired and wireless shared media concepts will be discussed.

what is Network Hub and Network Bridge?

In this class we are discussing about Network Device Hub and Bridge, Hub is a device used to connect multiple devices with each other and also using single broadcast domain and Collision domain while Network Bridge is a computer networking device that creates a single, aggregate network from multiple communication networks or network segments.

what is Network Switch? Difference between Layer 2 and Layer 3 Switch.

In this class we are discussing about one of the most important device i.e. Network Switch. Switch also works same as hub to connect different device with each other but it is different than hub because it can learn Mac address of devices which leads to unicast updates instead of broadcasting .we will also discuss about Single layer and Multi layer switches and their functioning.

what is Router and its Port Roles?

In this class we are discussing the device Router, which is used to define the route from one network to another network. Each router has different port to create network like Ethernet port is used to connect with local area network device switch whereas console port is used to configure the device and Aux port is used for modem connectivity. Serial ports used to make connection router to router.

Firewall, Repeaters, Gateway, Modem

In this class we are discussing the devices Firewalls which are used to prevent unauthorized access , whereas Repeater is used to regenerate the signal and modem is used to convert the signal. Gateways are used as an exit point of any network from where you can exit from your network to another network.

Class-4 Cables, NIC card and wifi card

In this Lecture we are discussing about cables, which is the important media to share our information from one to another location. We will learn about Optical fiber cable, coaxial cable and twisted pair Cables. Twisted pair cable having two types i.e. straight cable and cross cable. We will also discuss how NIC card and wifi cards store devices information in their CAM table.

Conclusion

Computers are useless unless they perform some service. Now that we've discussed some of the major Devices of networks. A good understanding of Network devices will help you to understand about working Media Connectivity in network easily. Now you understand that Network Devices are the reason you can easily communicate with people all over the world, and thus play a critical role in modern digital communications.
