Answer:
A page that gets a Didn't Load flag
Pages with an obvious problem with functionality or errors in displaying content
Explanation:
The main reason why a page gets Page Quality rating Low/Lowest is if it can't be shown for one reason or another.
A page with mismatch between the location of the page and the rating location, does have a mismatch but some form of a page is shown.
A file type other than a webpage displays that specific file type in a page framework, so page is shown
Other two do not show a page, so they will get a PQ rating Low/Lowest
Wait. What? What does that even mean?
<em>The answer is Crimper.
</em>
<em>
</em>
<em>Crimper is a networking device that would allow RJ-45 pins to get attached to UTP(Unshielded Twister Pair), CATs (Category Ns) and STPs (Shielded Twisted Pair) Cables. These are common type of cables used in computer networking. A crimper looks like a pliers only it has narrow ends with a hole where you would put RJ-45 devices together with the cables. In order to make the cable hold on to the RJ-45, the two hands must be squeezed together with an exact force (not too much force). Once the crimper made a sound, that means, your RJ-45 is now locked with the cables inside. </em>

<em>You must be very careful when using this device. Sometimes crimpers has blades that could peel off cables or cut them for alignment and proper attachments. A pair of gloves and googles are also advisable to wear when you use this device for safety measures.</em>
