I'm kind of confused on how ports work. So multiple things can use the same port number because they have different IP addresses?

Also, I've seen that multiple people can have the same IP address, so how exactly does a server know where to send the data?

Is using a RAID 1 configuration faster as well? Or is its main purpose so if you lose one of the drives you have a backup?

What did he mean when he said there's only a limited number or writes on a USB flash drive.

I've seen that people have used two graphics cards in a setup. How does this work exactly? I'm assuming you don't use the video outputs of both graphics cards.

How does DDR2 have a higher transfer rate than DDR if they have the same clock speed?

Why are jumpers a thing? It seems like there would be a more effective way of doing the things that they are used for.

So is the North bridge and South bridge configuration not relevant anymore? It's all integrated into the CPU?

What exactly does RAM affect in a computer? I'm assuming it has to do with speed right?

I sawn in this video that it talked about 32 bit and 64 bit connections. Does this have anything to do with wether your computer is determines as a 32 or 64 bit machine?

Does such a thing as 3rd party BIOS exist? Or is it specific BIOS to the motherboard?

I thought LoJack for Laptops was very interesting. Is this something that has to come already in your BIOS, or can it be installed?

RE: BIOS Configurations - CompTIA A+ 220-901 220-902 Video Training by Prof. Messer
Very helpful that you can run hardware diagnostics out of the BIOS, I had no idea that was possible. In the beginning of the video it talks about using fake BIOS. What exactly is fake BIOS and why would it be beneficial?

RE: BIOS and UEFI - CompTIA A+ 220-901 220-902 Video Training by Prof. Messer
I can't believe I never knew what BIOS was before this haha. Would BIOS have also been used in the early days of computers? Or is it only necessary because of operating systems.
