Then it's not using a modem. The definition of which is a device that converts digital data into a format that can be sent over an analog transmission medium.
You might have been trained to call it a modem, but a "cable modem" is a marketing term. It's not actually a modem, but closer to a network bridge or router.
Modems don't really exist anymore, they are all routers. A modem is a MODulator DEModulater, and converts digital to analog and back again for sending data over the old analog phone lines. ADSL is using the excess capacity using a digital signal over those same copper lines, so unless you use dial up internet you don't use a modem.
I don't know if it works on iPhone but i just connect my phone to windows via Bluetooth and get full screen mirroring on the PC. I can then setup alerts and features like auto lock and can attach a sound file to that action, so use that as an alert.
Not by using a scroll wheel on a mouse that's for damn sure.
Is that actually the problem you are having? Because you describe scroll wheel direction not swiping on touchscreen, which is a different setting in windows.
If you have to ask if somewhere is legit it most likely isn't fact is that unless they are an official reseller of licenses then it is not legit and you may as well pirate because that's what you will be doing if you use grey market keys anyway. (cheap keys usually come from bulk licensing deals that you are not a part of so effectively you are not licensed). If you don't want to pay the real price for the software license then don't use the software. MS offer online versions of the office suite for free, Libre office exists for people not wanting to pay for MS licenses.
Just for clarity that website is apparently offering you the full 2021 pro plus license for 40 times less than MS charges....how legit do you think that is? I mean they are claiming a one time fee of a single monthly payment for office 365 for unlimited access to the software...it's bullshit.
I went with a 3600x because at the time it was a decent cpu and came with a stock cooler, so overall was slightly cheaper. These days they don't come with a cooler, so you may as well go intel because it's cheaper AND performs better.
2 laptops 1 cup...it's possible, but it doesn't take long to make it spew out complete shit.
In other words there is software that will do what you want it to (actually a lot is built into windows due to surface tables having this feature OTB) but i have never seen it work flawlessly on anything but day 1 initial testing. Startup lag is an issue, but it's the things like changing where you are in a video or document that really grind on you to the point you end up never using it...and your no longer friendly CFO starts whining about wasted hardware purchases.
Your search terms suck. I went to amazon, searched "2 port usb charger"...boom first result.
Dual has way to many variants over what it can mean 2 port is very specific.
For a start, you refer to your potential customers as "the local nerds" stop that. Next you bought multiple limited offers meaning that those same "local nerds" missed out on the deal. Lastly the "local nerds" know what they are buying and who they are buing from, they will not pay more than $20-$50 over what you paid for the parts because that's what most shops charge for assembly...without warranty.
Either offer a warranty though a legit business you setup or suck up the fact that you didn't do your research before jumping in with both feet. Honestly it sounds like you have a bad attitude and I wouldn't want to buy from you because of that alone. Local nerds indeed.
