There should be a jump over the variables/array declaration:
org 100h
jmp code
myArray dw 2, 12, 8, 52, 108
code: mov si, 0
mov ax, myArray[si]
ret
For the computer all bytes look the same, it cannot determine if it's an instruction or a variable. Here is an example of MOV AL, 5 instruction that can be coded with simple variable declarations:
org 100h
byte1 db 176
byte2 db 5
ret
When you run this program in emulator you can see that bytes 176 and 5 are actually assembled into:
MOV AL, 5
This is very typical for Von Neumann Architecture to keep data and instructions in the same memory, It's even possible to write complete program by using only DB (define byte) directive.
org 100h
db 235 ; jump...
db 6 ; 6 - six bytes forward (need to skip characters)
db 72 ; ascii code of 'H'
db 101 ; ascii code of 'e'
db 108 ; ascii code of 'l'
db 108 ; ascii code of 'l'
db 111 ; ascii code of 'o'
db 36 ; ascii code of '$' - DOS function prints until dollar.
db 186 ; mov DX, .... - DX is word = two bytes
db 2 ; 02 - little end
db 1 ; 01 - big end
db 180 ; mov AH, ....
db 9 ; 09
db 205 ; int ...
db 33 ; 21h - 33 is 21h (hexadecimal)
db 195 ; ret - stop the program.
8086 and all other Intel's microprocessors store the least significant byte at a lower address. 102h is the address of 'H' character = org 100h + 2 bytes (jmp instruction). The above assembly code produces identical machine code to this little program:
org 100h
jmp code
msg db 'Hello$'
code: mov DX, offset msg
mov AH, 9
int 21h
ret
If you open the produced ".com" file in any hex editor you can see hexadecimal values, every byte takes two hexadecimal digits, for example 235 = EB, etc... memory window of the emulator shows both hexadecimal and decimal values.

Meta-assembler is a program that accepts the syntactic and semantic description of an assembly language, and generates an assembler for that language.

Assembler However, because the computer does not understand mnemonics, we utilise Assembler to convert them into machine language. Assembler is a machine code translator that accepts assembly code as input and outputs machine code. To learn more about data science please visit- Learnbay.co
A compiler accepts computer instructions in a language people understand and converts them into a language computers understand.
A speech synthesizer is a computer-based technology that converts text input into spoken language output. It uses algorithms to generate voice sounds that mimic natural human speech, enabling text-to-speech functionality in devices such as computers, smartphones, and smart speakers.
Yes, KLM accepts air miles. Please see this website: http://airmiles.klm.com/airmiles/ KLM, Air France, Kenya Airways and Air Europa also have they own "Flying Blue" Frequent Flyer programme, please see: http://www.klm.com/travel/nl_en/flying_blue/programme/index.htm

SQL stands for Structured Query Language as it refers to the type of database query or database server which accepts the query.
question clarity
It's difficult to determine the exact number of words in any language, including the world's largest language, English. English has one of the largest vocabularies of any language, with estimates of over 1 million words, including technical terms and jargon.
The plural of "accept" is "accepts."
