[@THHatch]

dude this stuff is gold, im blowing away my CSF 202 course cause of you. thanks

[@jooquaify]

Professor Messer!!!
Your videos blow my mind! Straight to the point, not fat!! Awesome!!!

[@senditall152]

Thank you for this great course!

[@christankelly7317]

I like your videos as opposed to a lecture in class. In lectures, the instructor likes to go on tangents and gives redundant info that is useless. in the time i went through talking about cables in class it took about a day or 2. in your videos i got through it in like an hour or so

[@joecha1092]

FYI toning out cable with foil shielding is a nightmare.

[@JuiceBoxScott]

Are you sure Cat 5 cable is capable of 1Gbps? The CompTIA book says it's data rate is 100Mbps.

[@professormesser]

I would recommend you read through the IEEE 802.3 1000BASE-T standard if you have questions about supported cabling for 1000BASE-T.

[@Chris.kovacs]

Are you questioning the professor? Haha jk

Cat5e gets up 1Gbps

[@_ZERO]

@@m_kago Cat5 also theoretically can reach 1Gbps like the enhanced version

[@gainsum]

I think it's important to note that when talking about Cat UTP cables. Cat 5 is a 100BASE-TX Ethernet standard. Which would be 100 Mbps up to 100 m.

[@professormesser]

This works the other way around. The Ethernet standard specifies the minimum cable type used.
For example, the minimum cable type for 1000BASE-T (Gigabit Ethernet) is a Category 5 cable and will operate up to 100 meters.

[@gainsum]

@@professormesser now I'm confused. Wouldn't the minimum cable type for 1000 be a Cat 5e?
Sorry, still new.

[@professormesser]

@@gainsum The minimum cable type for 1000BASE-T is Category 5, not category 5e.

[@kyru527]

To resolve any confusion for future readers, Cat 5 supports gigabit ethernet at a shorter range than Cat 5e+

[@professormesser]

@@kyru527 The 802.3 section regarding the Gigabit Ethernet standard (1000BASE-T) supports category 5 cable to a distance of 100 meters, the same as any higher category cable.

[@luisfarias4088]

Thamks to you professor i passed core 1 with a whopping 705 score! lol

[@mangu5128]

S = braided shielding? how come they didnt use B for this instead?

[@TracksWithDax]

@@nousquest actually "BS" might be a good way to remember that it uses S 😂

[@porkypine7114]

Because Comptia makes extra money from vouchers from people failing because they don't use common sense abbreviations😂

[@Candice144]

To make things unnecessarily complicated.

[@alethephobe7586]

S for shielding?
