It is possible to install Windows 8 using a USB flash drive with at least 4 GB of space. The process requires creating a Windows 8 ISO, or buying Windows 8 as an ISO, and adjusting the computer's BIOS to boot up from the USB drive rather than the hard drive.
It requires 192 GB of system memory. I am assuming that you are getting this question from the Windows & Configuration textbook by Craig Zacker, as I found that exact question in there. You can find the answer on page 15 in table 1-4. Hope that helps!

An 8 GB file cannot be placed on any file system supported by Windows 98. You could put such a file on an NTFS partition and use third-party software to access it from Windows 98, but programs on Windows 98 may have trouble reading or modifying it above the 4 GB boundary.
4 GB of memory is the maximum you can use in Windows XP, with only 3.5 GB of it seen by Windows.
4 Gigabytes (Gb) is equal to 4,194,000 Kilobytes (Kb), so at a page size of 4.2 Kilobytes (Kb), a 4 Gigabyte (Gb) flash drive can hold about 998,571 pages.
USB Flash drives are generic. No specific driver is needed.
It depends. Usually USB flash drives are measured in Gigabytes, and it should have told you when you bought it (you pay for what you get). Usually, a flash drive is no less than 1 Gigabyte, and no more than 4 Gigabytes.
The capacity of flash drives is increasing all the time. 4, 8, 16 and 32 Gb are common and very cheap. 128 Gb drives are available.
4 GB
Common flash memory chips can hold anywhere from 256 MB to 16 GB. In Secure Digital (SD) cards, any size greater than 2 GB utilizes SDHC technology (Secure Digital High Capacity) to allow the file system to hold a single file of 4 GB or more. A typical USB Flash Drive at 4 GB costs about 8 or 10 USD. Common flash memory chips can hold anywhere from 256 MB to 16 GB.
