🔌 Deep Dive into Ethernet Cable Categories
The second paragraph delves into the specifics of Ethernet cable categories, providing a comprehensive overview of their types and capabilities. It starts with Category 3 cables, which are unshielded and offer a maximum speed of 10 megabits per second at 100 meters. Category 5e cables are also unshielded and support speeds up to 100 megabits per second, with an upgrade to 1 gigabit per second. Category 6 cables can be either shielded or unshielded, supporting up to 1 gigabit per second, while Category 6a cables are strictly shielded and operate at 10 gigabits per second. Category 7 cables are shielded twisted-pair cables with the same speed capability as Category 6a. Lastly, Category 8 cables are shielded and can achieve speeds up to 40 gigabits per second. The video concludes with a summary of the Ethernet knowledge imparted and a thank you to the viewers for their attention.

Transcripts
today we will see the experience with
Ethernet as usual let's start the
session with the outcomes upon the
completion of the session the learner
will be able to outcome number one we
will know the pros of Ethernet outcome
number two we will know the cons of
Ethernet and finally we will know the
various categories of Ethernet cables we
will start with the pros of Ethernet
Ethernet is the most widely used wired
LAN technology when we talk about a
wired local area network Ethernet is the
predominant technology Ethernet is
relatively inexpensive and this is one
of the main reasons for the popularity
in Ethernet all the node have the same
privileges it does not follow
client-server architecture so if we want
to talk about all the nodes that should
have only same privilege then Ethernet
is a good approach we can take this
point as a both pros as well as a cons
and talking about the same privilege
level we consider these points to be one
of the pros of Ethernet as far as
Ethernet is concerned the maintenance
and administration are simple the cable
used to connect systems in Ethernet is
robust to noise so we can say Ethernet
is reliable as it is robust to noise the
quality of data transfer does not
degrade in other words the data transfer
quality is really good and finally with
the latest version such as Gigabit
Ethernet the transfer speeds in gigabits
per second have become possible we are
in the Internet era and we are able to
send data at the speed of 10 gigabit per
second and even more let's now see the
cons of Ethernet though Ethernet has
some advantages it has some
disadvantages as well under heavy loads
too much of networks capacity is wasted
by collision as I already mentioned
Ethernet supports collision detection
when two or more stations send data at
the same time at the shard medium it
obviously leads to collision and
Ethernet is able to detect the collision
and this collision is one of the
problems with ethem it so it does not
hold good for real-time applications and
interactive applications let me explain
why this is not suitable for real-time
applications and intuitive application
shortly after Network cannot set
priority for the pockets it is not
suitable for a client-server
architecture as he already mentioned
every station or node participating in
eternity ecology will be having same
privilege so there is no client-server
architecture with Ethernet since there
is no client-server architecture so
there is no chance to set priority for
the packets for interactive applications
dummy data have to be fed to make the
frame size 46 bytes which is mandatory
for interactive applications or for
real-time applications small data might
be transferred between the sender and
the receiver
but this compulsorily needs 46 bytes of
the data so we may have only one byte of
data to be transferred between the
sender and the receiver Ethernet somehow
have to make this one byte information
as a 46 byte information by adding
padding bit so as to make it as a
complete 46 bytes because the minimum
frame size in Ethernet should be of 64
bytes and the payload should be of 46
bytes and finally after receiving a
packet the receiver doesn't send any
acknowledgment Ethernet uses csma/cd
technology so there is no chance for
acknowledgments so far we have seen the
pros and cons of Ethernet now let's move
on to the next topic what is this
catch cutter of different kinds likewise
Ethernet cats are also of different
kinds heathyr net cut it's a new
terminology that I am introducing I
request you not to search internet
regarding this rather search for
Ethernet cut cables so the topic of the
session is Ethernet cut cables so I have
simply noted as cars we have many
categories of Ethernet cables where I
have listed Ethernet category 3 5 5 v 6
6 a 7 & 8
Ethernet cables comes as a twisted pair
cable we also have shielded twisted pair
as well as and shielded twisted path in
short we will call it as STP or UTP
talking about Ethernet category 3 cables
they are unshielded that is UTP cables
and their maximum speed is of 10
megabits per second and this maximum
transmission speed at 100 meters and
coming to
category 5e cable and these cables are
also unshielded they come at the maximum
speed of 100 megabits per second coming
to cat 5e it is also of unshielded
cables and it comes as 1000 megabits per
second or 1 gigabits per second and we
also have a variation of cat5e cat6
carefully so fully unshielded Miraz cat
6 is of shielded or unshielded so we
have category 6 cables that is Ethernet
cat 6 cables it is of STP or UTP which
fields up to 1 gigabit per second and
cat 6a is strictly a shielded power
cable which works at a speed of 10
gigabits per second and cat 7 is also a
shielded twisted-pair cable which works
at a maximum speed of 10 gigabits per
second and we are in the contemporary
world with category 8 cables they are
shielded twisted pair cables it speeds
up to 40 gigabits per second and that's
it guys I hope now you know the pros and
cons of Ethernet and we also know the
various categories of Ethernet cables I
hope you enjoyed the session and thank
you for watching
