I'm super awesome and super proud to tell you that you have finally reached the end of this section
of networking devices through this chapter, covered quite a bit of information.
You learn the difference between a router switch and a hub and then to use each one.
I also cover some devices that you might find in the network today, but not as often, such as VPN
concentrators and content filters.
The information I discussed about DNS and DCP is critical to your success on different examples like
Network plus Kenay and many more, and highly suggest that you re revisit those sections because generally
questions are being asked on the DNS and other things I do interview.
I covered how both the DNS and DHP services work on the network, and I also discussed about the DCP
operations.
If you remember, in addition to the most common devices, I discussed the specialized network devices
mentioned in the network objectives of the exams.
I finished the chapter or the section by discussing collision and the broadcast domains, as well as
how would you use a router and the benefits of routers.
All of the information in this section is fundamental and you must understand it before moving on to
the next chapters or the next sections of this course.
So if you have any doubts, I recommend you to please revisit all the sections if you have any doubts.
So what do you need to focus on?
You need to focus on how DCP works and its purpose.
Dynamic Host Configuration Protocol provides IP configuration information on to hosts.
It is important to know how or DCP client requests information from a server, how a server receives
this information, and also how the server responds to the client and with what type of information.
Now I will tell you one thing that whenever I, I tell you about a quick recap or what you should focus
on, it is the mantra that you should always follow while starting computer networking at the end of
each section.
I have a quick recap video which will tell you exactly what do you need to focus to get you certified,
as you see in your network exam or anything on the questions on these topics will be asked in your exam.
Mark my words.
Then next, you should understand how DNS works and its purpose.
This domain name service is used to resolve human names to IP addresses.
Understanding how DNS resolves these names is critical, as is understanding how our DNS square is sent
and how our DNS server responds.
Then you need to understand the difference between a hub, a switch and a router, a hub just connects
network segments together, a switch or a big segment of the network using Mac addresses and router
segments, the network using logical accuracy, that is, the IP address switches up collision domains
and routers break up broadcast domains by default.
Also, remember the different names for a daughter, a daughter is also called a military hardware switch,
but it can also be called a multilayer switch.
Then remember the various devices used on networks today and when and how would you use them in different
scenarios?
And finally make sure that you understand the working of proxy servers and access points as these two
devices are commonly used in today's Internet?
