A computer network is a group of devices connected with each other through a transmission medium such as wires, cables etc. These devices can be computers, printers, scanners, Fax machines etc. The purpose of having computer network is to send and receive data stored in other devices over the network.
We shall study about the definition of computer networks. Then we study in brief about data communication, networks, protocol and standards.
Basic concepts includes topics like line configuration, types of network topologies and internetworks.
In this chapter we will study the OSI model and TCP/IP model.
The chapter will teach you about different types of transmission media, transmission impairment, Performance and shannon capacity.
Here we will study about types of errors that occurs in transmission of data and how to detect and correct them.
In this chapter we will compare the types of models, protocols,architecture, cables and topologies that we have learned in the above chapters. Then we will also learn a new topic i.e IPv4 and Subnetting.
Here we will start with switching concepts like why they are called more intelligent then routers, how they store the MAC address of all nodes in the network. Then we will learn about ethernet the term which is used usually in the field of networking. After all this, we will see what are the troubleshoot interface and cable issues that occur in a network. At last, we will configure layer 2 protocols.
One of most intersting chapter in this course, here you will learn about IPv4 addressing, next topic is Subnetting and at last we have configured VLAN for two teams. These topics are very important to understand in the field of networking which is very difficult to understand for many people but here we have the simplest explanation.
This chapter mainly focus on the practical part. We will configure all the routing protocols in this chapter. We will configure both the static and dynamic routing protocols. So lets start with it!
Here I have configured the both types of NAT protocols that are static NAT and dynamic NAT, also I have mentioned all the commands by which you can also implement NAT. Basically, NAT enables private IP networks that use unregistered IP addresses to connect to the Internet. So let's see learn how to implement in packet tracer.
