Okay, these guys have this computer advertised: Lenovo ThinkPad Edge E550 20DF
These first six specs are clearly understood...
- 8 GB RAM
- 500 GB HDD
- DVD-Writer
- 15.6" 1920 x 1080 ( Full HD )
- 802.11ac
- graphite black
No Clue on these next two. Going to google. I think the Radeon is (or was once) a graphics card. I don't have any idea of how to put the first one into my brain, as a quantity, and then get that qualitative concept which flows out of the quantifiable item.
- Core i7 5500U / 2.4 GHz <---The "core" of my confusion
- AMD Radeon R7 M260
I think I know what these next two mean; and it makes me go "HUH ???"
- Windows 7 Pro 64-bit / Windows 8.1 Pro 64-bit downgrade
- pre-installed: Windows 7
I think this last one is a part number
This is the kind of stuff where I don't really understand what stores are telling me when they advertise a notebook computer. I'm sitting here asking myself what I'm getting for what I'm paying, and no clue on how to compare that against another machine with equally convoluted specs.

Radeon is a graphics card from ATI (and a rather good one at that), and the CPU is an Intel i7 5500U (the number 5500U is a model number), running at 2.4 Gigahertz.
Did the specs really say a downgrade? If they did, they were right.
What do you get when you cross a joke with a rhetorical question?
The metaphorical solid rear-end expulsions have impacted the metaphorical motorized bladed rotating air movement mechanism.
Do questions with multiple question marks annoy you???

Yes[^]

They mean if you choose to use Windows 7 on it instead of 8.1 (or the newer 10). Depending on your needs, you may opt for one version or another. For example, in my regular business needs, I need a lot of software that I KNOW works on Win7, so if I need a business laptop, I'll choose that. On the other hand, if it's a personal computer, I'll probably choose the latest and greatest.

Is there a place where I can get a visual matrix of which CPU has what parts inside ?
i.e., some way to compare apples to apples.

Not sure. Google doesn't turn up anything.
I found a couple benchmarking sites:
CPUBoss[^]
And
CPUBenchmark.net[^]
But that's about it.

Err... CPU is the Central Processing Unit... i.e. there's nothing inside of it other than the microscopic transistors that make up the logical elements.

Some have 2 cores, some have 4, and some have more.

Yeah, that's something you can easily look up though. It's sort of trivial at this point that most CPUs have multiple cores and a shared memory cache.

A lot of people still prefer Windows 7 over 8.1 or 10 (including yours truly). I'll upgrade on my own time, I have work to do.

Well none of that is specific to notebooks, most PCs of any configuration from tablets up will have some combination of similar items.

That is the Intel Core i7 processor running at 2.4GHz processor clock rate. The intel website will give you the full details and comparision with the slower i5 and i3 processors.

One of the AMD graphics processors that provides the high resolution video.
The various Windows versions that you can (presumably) opt for.
All of which can easily be found by Google.

Core i7 is just the product of Intel processors. If something isn't clear, Google is always there for you. Since the processor isn't clear, try this resource from Intel to learn more about that product of theirs. http://ark.intel.com/products/85214/Intel-Core-i7-5500U-Processor-4M-Cache-up-to-3_00-GHz[^]
Same thing for the Graphics card (yes, that AMD is a graphics card for your machine). What about this link to learn more about it? http://www.amd.com/en-us/products/graphics/notebook/r7-m200[^]
Windows version and the final notebook product item number are a few things that you would be using to find hardware or drivers related to your machine. Windows product is what you can change while purchasing the product. You can select from Windows 7 or Windows 8.1 Pro, your choice.
If you find difficulty in learning something or understanding, always try to Google for it. Google has a good base of search results for you.

Each and every machine that a manufacturer provides has a clear table list for their specifications. I have, as far as I searched, found it very easy to read the specifications for the machine.
The only thing that might make it hard for you to read and learn the specs is the UI and UX of the website. Can you point me to a notebook which doesn't have specs clearly written or explained?

I asked the internet search engines, and came across conflicting experts. (Who'da'thunkit ?)
If we build a card with a video camera which uses a Bluetooth connection back to "home base" so to speak, can we expect a robust and clear video result for the user ?
I'm not clear on how to do the arithmetic.
What times what, divided by what, gives me what result ?
Then of course, I need to consider things like theoretical scientific stuff on the internet -vs- what we're going to experience in real life; but that's a different conversation.

In theory the data should be as good as any other transport mechanism, but only testing can tell you for sure. You do appreciate that Bluetooth is only for very short (<10 metre) distances?

Understood. The existing design ("dream" might be a better word after some recent feedback from my gang at work) will be boxes in the attic. It's all up in the air now.
Might not even happen at all.
Oh well, I thought it was a pretty good idea.

Bluetooth doesn't penetrate walls (and ceilings) very well. I think you'll face a lot of signal quality problems.
The difficult we do right away...
...the impossible takes slightly longer.

Something else to keep in mind are the data rates available in the Bluetooth standards. The rates are pretty low, so you could stream video but you'd have to do a bunch of compression and probably accept the fact that the video won't be all that good. Bluetooth works for audio because the data rates of compressed audio are very low.
See Bluetooth rates here (under "uses"): https://en.wikipedia.org/wiki/Bluetooth[^]
In contrast, WiFi rates are significantly better... so system design question to you might be, you can use Bluetooth, but why would you? What are the benefits from such a system?

Check.
Bluetooth is out for this gig.
The reasons you enumerate are exactly what went through my head.
Obviously, you're a smart guy.

I hope this is the correct forum for such questions..
Is an adapter (the wrapper, that is) really needed in order to put a nano SIM into a micro SIM slot? I tried without one and there doesn't seem any problems. So, my question is, if I continue like this, apart from trivial "non-detection of the SIM card case", what is the worst that could happen? Agreed, those adapters are so cheap to buy, but just wondering...
Thanks in advance.
You have just been Sharapova'd.

You can short the voltage/ground leads that are going to the card. That could potentially mess up your phone since the source that would burn out would be in the phone and not the SIM.

Why are you stressing on sim adapter

What questions should I ask about surge protection and Uninterrupted Power Supplies ?
What's important ? What's marketing mulch ?
At the moment, I don't really have the vocabulary to know how to read the ads.
What numbers are real stuff, and what numbers are so what ?
Thanks for any education you might care to offer. It'll help a lot.

Just a small hint: You might want to watch out for idle cooler noise if you plan to use it in your office. I once bought one where the description said nothing about it and even in idle it was many times louder than my PC
