Each individual Datajack is still only a single connection to your one and only brain. Please forgive me for any smugness or pedantry that might become evident in the post to follow. My reasoning chain follows:
Thanks for the warning.
1)
So, therefore Commlinks or Cyberdecks are Required to form a PAN and possibly attain connectivity to benefit form Wireless Bonuses.
You're looking at the quote very literally. While I agree that a Commlink or Cyberdeck can create a PAN, I disagree that those are the only devices that can do so. For instance, a Rigger Control Console can control a fleet of drones via the PAN. And there's no reason to believe that it cannot be a master at all.
2)
Consequently, while everything can send data out to HOSTS for data analysis to optimise situational performance, not Every device has processing power/Device Rating to handle the data transfer to the Matrix.
Not true.
if it’s big enough for a microchip, it’s big enough to house enough computing power to be a device. And if it’s a device, it’s in the Matrix.
So everything big enough to hold a microchip is a device. And every device has a device rating (as denoted on the Device Rating table on page 234). Ergo, every device has a rating and can be connected to the Matrix.
3)
Commlink and Cyberdeck charts on page 439 of SR5.
We see clearly, and explicitly, that Commlinks and Cyberdecks have Device Ratings and thus processing Power.
Looking at the Device Ratings table on page 234, you can clearly see that all devices have a Device Rating. From the lowly toaster to the highest-end cyberdeck.
4)
A Datajack can only interface with A (singular) electronic Device.
If you feel like it, you can look through my post history and you'll see where I made the exact same argument as you did. In fact, I did it rather brusquely and the conversation got a bit heated as a result. My argument was that a datajack has to be connected via fiber optic cable to a commlink, which hosts the PAN. However, based on conversations that I've had with developers and with Bull (the Missions coordinator and employee of Catalyst), I was corrected. A datajack can host multiple devices, provided the connection is wireless.
5)
Headware chart on page 453 of SR5.
Datajacks definitely have NO Device Rating or it would be listed in the table.
Datajacks don't need a device rating on that table because it's on the Device Rating table on page 234.
Now we pair up SR terminology with some RL terminology that mot tech-heads understand to contextualize their functions. Interface (input and output hardware)/DNI, Router (center point for a small-scale network)/PAN, Processor/Device Rating, and Connectivity (benefits gained for communicating between hardware)/Wireless Bonus. So Datajacks and their forefather the electrode serve a the user's Interface, while the Commlink and their big brother the Cyberdeck serve as the PAN's Router, and the Wireless Bonus is the benefits gained from connectivity with the Matrix.
I'm what you might call a tech-head (I've got 25 years of IT experience, about 10 years of programming experience, and about 10 years of system and network administration experience), so I get the terminology. Unfortunately for this logic, none of the technology of 5th edition has any basis whatsoever in reality. In fact, at the beginning of the Matrix chapter it explicitly states as much:
The paradox of the Matrix is this: to be an ace hacker, you need to understand it—but no one really understands it.
So'ka?
I do not think that means what you think it means. What I believe you meant to ask is "wakarimasu ka?" which means "do you understand?" What you instead said was akin to "I get it?" Honestly, if anything about your post came off as belligerent, it's this because A) the phrase is not correct and B) the phrase is unnecessary. Saying it in a foreign language assumes that either I speak Japanese (which I do somewhat okay) or that I'll spend the time necessary to look it up. It's totally unnecessary and a little insulting.
