Professor giving out false information

[mralexkohl1993]

 So guys I have a problem. I'm in a I.T. Course at one of my local technical colleges and the professor I have just doesn't know. He gives out false information all the time. Like one day when I corrected him in class and had an argument it was about sata 6 gb per second. He said that mechanical hard drives should be plugged into it or they won't operate to their full potential. I was just like no. Sata 2 doesn't hit the theoretical throughput of what a mechanical hard drive can supply so why use sata 3? He just argued and argued. Today he told a student I shit you not "hyper threading means that a CPU has 8 logical cores" I didn't say anything. He said that within each core itself is 2 cores that have their own L1 cache and share L2 cache between the 2 cores then have L3 cache for all the cores to share. I'm just like wtf.jpg He also tried telling me that you can have a motherboard with just 3 ram slots that can run in triple channel. Not 6 like on 1366 but just 3 I'm like wtf. He also tried telling me that you need a 50% headroom in a power supply. So if your system consumes 600 watts it should be at least 900 watts and this is for "power surges" 300 watts for power surges wat. 

 

I don't know what to do about this. The guy is smart in some respects but other I'm just like why is he teaching. I feel like I should approach a higher up because students shouldn't be getting the wrong information when they are paying this kind of money for an education.

Hyper threading is a software functionality. Hyper-threading allows each core to run two threads. However the hyper-threaded processes run in between read/writes from and to RAM, which is what the extra cache is for. Though programs do recognize threads as logical cores. In that regard, he is correct. As for SATAIII and SATAII, if you plug a SATAIII hard drive into a SATAII port, you will not notice a difference. In fact, you could probably plug it into a SATAI port and you wouldn't notice a difference, because SATAIII hard drives still don't utilize SATAI to its fullest potential.

As the guy from planet Mars said. ^^

 

And also, quit this thing right NOW !

 

Or report him to the concerned authorities.

[Jack.EXE]

Nope.avi

[Bluejay0]

I want to go, tie him up, put him in a closet, and get the WHOLE LTT FORUM to teahc that class. That man speaks bull..

[Lil Chillbil]

We should all email him, everyone on the ltt forum and just correct him and cal him mean names like stuipidface and tell him to resign 

[Vitalius]

While I admit he sounds dumb as he is wrong about everything else, he is kinda right and kinda not about the triple channel motherboards.

There are two versions of LGA 1366 socket motherboards, one has 4 DIMM Slots and one has 6 DIMM Slots. The 6 one is for 2 setups of Triple Channel RAM, as you mentioned.

The 4 DIMM Slot version is for a single Triple Channel setup and a single Single Channel setup:



Then there are 3 DIMM Slot motherboards which he is probably thinking of when he says that:



But those are ancient (DDR RAM) and do not support Triple Channel setups.

My IT teacher from a few years ago was worse.

• Adobe is malware because it updates.
• 'SSDs' are used in phones
• open source means things like google docs
• she wouldnt know what a cpu was if you were to ask her 
• I doubt she would even know what hertz are
• SATA, whats that
• computers overheat if you leave them switched on overnight
• The computer itself is called the hard drive

[SkilledRebuilds]

I'd go to higher channels, directly quote him, and then provide actual fact, proving that he is giving out false information, and that he shouldnt be teaching if he isnt properly trained in what he is teaching.

He will only cause more problems the longer he is left in that class teaching wrong, and if no1 stands up, everyone falls.

 

Do something about it, and help your fellow man-tech's!

no they arent logical they are theoretical.... completely different

Each thread is counted as a logical core. This includes the threads you get without hyper-threading.

*looks for book of all my knowledge* Where is this teacher?

[CwGoh]

Gosh. Thanked god my IT teacher when I was in Primary school only taught me how to touch type...

yes but he is saying that within a a core is 2 cores.... hyperthreading doesnt work that way

[Godlygamer23]

Now I see what you're saying. However, a hyper-threaded core is also a logical core, since it's just another thread.

yes i understand but im saying that its not a real core as he describes it 

[Godlygamer23]

You are correct.

I am sure you will be a great gramma teacher

[Dravic]

I am sure you will be a great gramma teacher

 

I am sure you meant grammar*.

[vanwazltoff]

i have only had ONE IT teacher that i havent had to correct multiple times daily....i feel like i should be teaching the class

[Warcony]

Most IT and engineering professors give out incorrect information all the time related to tech.  This is due to the fact that they have been, for the most part, disconnected from industry for years and stuff changes so fast.  It also doesn't help that a lot are arrogant by nature and think that reading 2 paragraphs on something instantly makes them an expert.

I didn't say i was a great teacher..

This. This. This.

 

This is why YOU SHOULD go to a higher up... make a change for the better. Hell, use the quote ^ there, although it wont be received well, it applies.

 

Should the OP take this further so PAYING students can actually LEARN some facts instead of "Opinionated fact"?

How should it be taken further, what are the best channels and way to do so, anonymous or not...

[HiiraTeruyo]

I think it'd be worth it to at least have some kind of discussion with a higher up, it doesn't help much that many people don't bother to really learn in-depth about the devices that they use everyday, but when the people who do want to learn that are being taught outdated or varying degrees of inaccurate information, I think something should be done about it.

a hyperthreaded quadcore has 8 logical processors... how is he wrong there?
