Can I store a program on a USB Ethernet/WIFI adapter and auto-run the program when the usb wifi adapter is plugged in? Is it scenario where it may be possible on some but not other USB wifi adapters?
Rees-pek!
In short, no.
However, most of the Huawei 3G/4G devices have a virtual CD-ROM drive built-in.
And yes, you can modify the firmware to run your own code (It's an ISO image).
On a regular WiFi USB adapter, best chance would be to add an USB hub chip and a Arduino Teensy to send commands, yet, would be very big to fit in the original casing.
Or, just plant some regular USB flash drive inside the USB Wifi plastic casing.
Out of curiosity, why would you want this ?

I searched for a solution to reboot raspberry pi 4 after shutting down but only I can find that you wire a switch to reboot it. Is there a program or a script to remotly start up raspberry pi by pressing some button on the keyboard. Because I am using mine a smart tv replacement and want to know is it possible to reboot remotly without getting out of bed? :D
a good solution, which I tested is to directly connect the raspberry pi to the tv via usb, so when you turn on the television as the command the rasp also turns on :)

For an ethernet connection between 2 points which will be used as point to point communication (for embedded devices). Is internet connection, hubs or switches are really necessary? Or can we still send and receive data from one MCU to another one by using ethernet without using any internet connection, hubs or switches?
There's certainly no need for an Internet connection.
If you want to connect two computers together directly, then you will need to use a crossover cable rather than a patch cable unless the devices you are using support auto MDI-X.
Putting a cheap hub between them will probably be simpler.
No, they are not necessary. We ofen do this between either two of "product board", "FPGA board", and "PC" when debugging ethernet Tx/Rx issues.

I would like to know if it is possible to configure Raspberry pi to work as Wifi AP and client simultaneously. I googled and found the following link
Link
This link is not clear but it makes a reference to this Link-2
Link-2 has something mentioned like this: It seems likely, given the chipset, that the Raspberry Pi should be able to operate in both Access Point mode and client mode simultaneously. In other words, it can get its internet connection by joining on a wireless network, while simultaneously providing a second network as an access point to a ‘cloud’ of sensors. Which is what i'am looking for. I tried googling more, but could find setting up Raspberry pi as a Wifi AP only but not both simultaneously.
My question is: Is it really possible to set up Raspberry pi in with such a configuration mentioned in link-2. And if so can someone please tell me step-by-step to do it.
I have Raspberry Pi 3B with Raspbian Stretch.
You can't have multiple wifi services with single wifi-interface(built in interface).This is common to all devices not only raspberry pi.
What you could do is to have a separate USB wifi interface(adapter) for that.There are good external USB wifi adapters to purchase in very cheap prices as well.
Try one...

my virtual machine (VMware macOS) doesn't see my iPhone when I connect my iPhone to the computer. Anyone knows how to handle this ? I want to connect just for using my iPhone as simulator.
I think that your iPhone with the lightning connector would be perceived by VMWare as a USB Device, so you could refer to their USB Device documentation. The TL;DR is essentially:
Add the physical usb port to what the vm can "see".
Choose VM > Removable Devices to connect specific USB devices to your virtual machine.
Find the menu item for the usb port the iPhone is plugged into and mouse over it to see the iPhone, then click its name.
I found some additional instructions here which may provide more useful, granular details on how to do this. Pleas note that you will have to take into account the OS of both the host and the guest when following the documentation. Additionally, you may need specific drivers to let the guest addition recognize the iOS device.
Good luck!

I bought a Raspberry PI and connected to one of my Sony Bravia's HDMI port. I got unsupported signal, check your device output error. I have another TV, another model of Sony Bravia, that TV can display Raspberry PI's output. My first TV support video signals of 1080i, 720p, 1080p and display resolution is 1366 x 768. I looked for the similar problems and some people complain HDMI cable problem. But not sure, it is cable problem. I think it is setting problem. Is there any setting in Raspberry PI for HDMI output.
I had the same issue and resolved it with another hdmi cable ! The new cable was quite a bit shorter but worked fine .
