comment Does disk partitioning impact performance?
"Partioining your hard drive will generate two (or more) virtual drives" -- No, they are called logical drives.

comment Use of single board computers in real world
SBCs are used in a wide variety of consumer, commercial and industrial products. But they are more likely to be custom boards based on an SoC designed specifically for that product rather than an off-the-shelf SBC that you're thinking of. BTW semiconductors and other electronic components are rated for temperature and other life expectancy factors. Industrial SBCs have better components (i.e. higher ratings) than an RPI, and are priced accordingly (e.g. 2x to 20x more).

comment What “device” represents between socket and network
The network card, or more specifically the Ethernet controller, aka EMAC.

"I cannot confirm that OS is running" -- A serial-port console would solve that. See superuser.com/questions/440857/…

comment Why does TV interfere with WiFi?
Where is all of this equipment physically in relation to the TV? I've experienced EMI from a TV's power supply disrupting 2.5GHz signals. Consider the signal path as well as proximity to the TV.

comment Is it safe to assume that a mobo of a given form factor will not be even 1/2 a inch larger than the specified form factor?
@barlop " the motherboard in that pic is not a square shape" -- Not uncommon for low-end or newer microATX mobos.. The 9.6"x9.6" spec is for the maximum size, not a required size. I have such a mobo that's "short" in the depth dimension. The manufacturers can save a bit on costs by making the boards only as large as it needs to be, rather than the "full" size. Correction to previous comment The box is for an ASRock microATX mobo, not miniITX, and it has the "short" depth.

You "measure" these mobos yourself. Get a photo of the mobo from a site such as newegg.com. Use the DIMM socket as a reference, and measure (with calipers) the board in the photo, then scale to actual size..

"I've been given the mobo dimensions, it is 10.8 * 9.4 * 2.6 in" -- Interesting, that's close to the dimensions of the box that my ASRock miniITX mobo came packaged in. The phenomenal growth of the PC industry is largely due to adherence to standards, starting with the IBM PC and PC-DOS. A motherboard spec'd as "MicroATX" should conform to the specifications, or else the manufacturer risks product returns and lost revenue. There is simply no benefit to the manufacturer to mislabel the formfactor.

comment How to determine air intake holes in pc case
"Generally fans suck the air inside and air leaves your case at the other holes" -- You seem to be contradicting yourself. Every PC PSU fan I've seen blows the air out of the case, not in. When there's only one case fan, I've only seen them blow out of the case, not in. The vents and holes are for air intake, not exhaust.

"11 x 11 x 3.5 inches" -- That's the dimensions for the package. A generic microATX mobo has a 99% of fitting into the HP case. I did something similar a while back.

comment Links and transmission rates
"why should I wait a whole second before transmitting the next?" -- You need something to send each bit at a given rate, and something on the other end to receive it. The electronics to modulate the data and then demodulate the signal have finite speed. Your conceptualization of nice square waves for digital data does not exist on transmission wires.

comment Links and transmission rates
"Ones and zeros are expressed by different voltage levels." -- You're describing amplitude modulation, which is only used on circuit boards and slow&short transmission schemes such as RS-232 and IEEE-1284. Modern high-speed communications use both phase and multi-level amplitude to modulate the digital data onto the analog carrier, e.g. QAM and PAM.
