What else can I help you with?
If a computer has a maximum of 2N memory cells then each address field in a machine language instruction must be how meany bits wide to enable us to address every cell?
If there are 2^n cells then you need at least n bits to address each cell individually. For example, if there 2^32 cells then you need at least 32 bits to address each of the cells. 2^32 = 4,294,967,296 cells The cells are numbered the range 0 to 4,294,967,295 (inclusive). In hexadecimal notation this range becomes 0h to FFFFFFFFh. The upper bound has exactly 8 hex digits. Each hex digit represents the 4-bit binary value 1111. 8 x 4 bits = 32 bits. QED.
Does 3EO and 3Eo means the same in hexadecimal notation?
Hexadecimal uses the digits 0-9 and the letters a-f (in either upper case A-F, or lower case a-f). You appear to have used a letter O in upper case and lower case (o). Neither is a valid [standard] hexadecimal digit; so 3EO and 3Eo both mean the same in hexadecimal: a non-valid number. 3E0 and 3e0 are both valid hexadecimal numbers that mean the same (as the decimal number 992). In C, to signify a hexadecimal number it is preceded by 0X or 0x (that is zero-letter X), as in 0x3E0, etc.
What are the memory addresses from 0 to 640kb known as?
The memory addresses from 0 to 640 KB are known as conventional memory. This range was primarily used in early personal computers, specifically in the context of the x86 architecture. It was the area of RAM available for use by MS-DOS and older operating systems, where most applications and programs would operate. Beyond this range, from 640 KB to 1 MB, is known as upper memory.

Why is it desirable to load device drivers into upper memory rather tnan conventional memory?
Most DOS applications utilize conventional memory. Many DOS applications can not utilize extended or expanded memory without special software. When you load device drivers into upper memory, you leave more conventional memory free for other applications to use.
