This course aims to be a complete course for the CCNa, including everything you
need to pass the exam. this course is for anyone who wants to learn about computer
networking.. The only requirement for this course is that you have a basic
familiarity with computers. i will cover all of the foundational networking
knowledge at the beginning of the course, so you don t need any prior knowledge of
networking.. A computer network is a digital communications network which allows
nodes to share resources.. Wikipedia defines a network as a network that allows
people to use resources. what exactly is a node. let s build a network and examine
each type of node in a network.. The last symbol in this slide is a client. a
client is a device that accesses a service made available by a server. to
understand. One of these is part of the definition. of a client, you have to
understand the other. in fact,, any of the clients we looked at in the previous
slide can be servers too!!
data from your computer passes through the internet to reach the Youtube server.
the exact details of the internet aren t important for this diagram, so we can
simply use this cloud to represent the internet. a client is a device that accesses
a service made available by a server... A server is a devices that provide
functions or services for clients. a real enterprise branch will have more than
just a couple PCs or servers.. switches are used to forward traffic within a Lan, a
local area network. These switches are Cisco 's enterprisegrade switches used by
many enterprises to connect their Lans. switches do not provide connectivity
between LanS or over the internet. to do so, we need another kind of network
device. that device is a router. we can connect the switches to routers like this,
and then connect the routers to the internet. we ' ll. cover the details of Lans
later. firewalls are specialty network security devices that control network
traffic entering and exiting your network. they protect the end hosts inside,, like
the PCs and servers in this network.. If the attacker tries to access anything
inside of our networks, the firewall should block it. the IsR 900 router has
relatively few network interfaces compared to switches. routers are used to provide
connectivity between Lans..
Firewalls are known as nextgeneration firewalls when they include more modern and
advanced filtering capabilties. these are the kind of firewall we will focus on in
this course as it is a networking course.. There will be three primary resources
[UNK] endofvideo quizzes. After each video. premade flashcards to review the
lecture material using the flashcard software anki. cisco exams tend to have lots
of questions like that so hopefully. Some of these will be able to test you in a
similar manner. the Packet practice lab for this video will be a demonstration of
how to download packet tracer and get started with it. now, let s go on to this
video s quiz quiz. select the best answer from the available choices. a server is a
device that provides functions or services for clients. in this case, your friend s
phone provided the file to your iphone. so,. A, a server is the correct answer. B
is an end host.. C is a client.. D is a router. your company wants to upgrade its
old network firewall that has been in use for several years...
The answer is C, a nextgeneration firewall. a hostbased firewall is a piece of
software that runs on an end host. it is not a network firewall.. nextlevel and
Toplayer are not actual types of firewalls. so C is correct..
