How can we tell from a WiFi card spec whether the NIC is 2.4GHzor 5GHz, or both?

I am lost on the questions and answers that you guys are posting.
I never hear of different WiFi to me all are universal speed depend
on your OS system, and the host and router if in use. as much I know
all laptops
have capability to hook to WiFi but you will need password unless system
is open.
no to many of those around but you can be lucky.

How can we tell from an HP WiFi card spec whether the NIC is 2.4GHz or

I'm trying to help my sister buy an HP laptop on the web.
My problem is that I contacted HP Support (via their chat mechanism)
because USA
phone support is not open now, and technical support isn't open tomorrow.
All I want to know is HOW to tell if a WiFi card has both 2.4GHz and 5GHz.
For $300 at Costco, plus $30 for shipping, this seems to be a decent
15.6-inch
display laptop:

The main drawback from that Costco offering is that the WiFi isn't "ac",
there's
no mention of bluetooth, and the laptop doesn't come with Office 2013.
But, we can fix that at the HP web site.
If we go to the HP site to buy it, we can customize it to add what
Costco doesn't
have (and get free shipping).

0. We start with the HP price of $350 which comes with twice as much
memory as
Costco's (4GB - 8GB) plus free shipping (worth $30), so it's only
$20 more
than the Costco price.
1. We add the Microsoft Office Home & Student 2013 from HP for an extra
$140 (either
boxed, or already installed - I suggest they get the box for easier
re-use later).

2. We add a WiFi "ac" card from HP for an extra $30 but is it dual band,
2.4GHz and
5GHz or not?
3. We add an extra wireless mouse and keyboard (no wires!) for $30
(because my sis
wants that).

The resulting price is $550 + tax (free shipping).
For that price, I see she gets a good laptop, but I chatted for half an
hour with the HP
sales chat people and they couldn't confirm if this 802.11 n/ac laptop
has both
2.4GHz and 5GHz or if it only has one of those two frequencies.
HP chat sent me this URL but it just confirms that both "ac" and "n"
don't have to be dual
band; either one can be a single band. Also, it confirmed the 1x1 or 2x2
or 4x4 just means
the number of dedicated data transmit and data receive antennas, which
says absolutely
nothing about the frequency.

My question is ...
How can we tell from the HP WiFi card spec whether the NIC is 2.4GHz or
5GHz, or both?
