If Windows recognizes it, it should show as a COM* port.

comment How to open a file in binary format.(1's & 0's)
2) Good hex editors simply don't load the whole file; they load only as much as they need at that moment. Your screen is not infinite, you can see only a few kilobytes at a time – so of course the editor just loads a few kB at a time and updates it as you scroll. (Hex editors can do that because the entire file looks the same; no separate lines, no word-wrap.) Just like video players don't need 5 GB of memory to play a 5 GB movie, and games don't need 100 GB of memory to run a 100 GB game, hex editors can easily edit even terabyte-sized files – hex vs octal vs binary makes no difference.

comment How to open a file in binary format.(1's & 0's)
Sorry, but this is garbage. 1) Editors don't "open" things in hex or binary, they don't convert the whole file to individual bits or hex digits when loading it to memory. The file is always loaded "raw", 1 byte in memory = 1 byte in the file, and only the visible area is shown in hex or binary format. So a 10 MB file would still need only 10 MB of memory, not 20 and not 80.

comment du and ls report different directory size?
blockdev reports the device's block size, which is not the same as a filesystem's cluster/sector size. For example, it's very common to use 4k or 8k clusters on a 512b disk.

comment How to find the wireless MAC address (aka BSSID) of any wireless access point
No, it isn't. Wi-Fi access points are similar to Ethernet switches – they only care about Ethernet packets and a specific device is identified by its MAC address and "Basic Service Set ID" is just a fancy name for that. (While most APs do have IP addresses for purpose of adjusting configuration, usually you cannot find that out in any way.)
