1. **Assembly Language** - It is a type of low-level programming language that is intended to communicate directly with a computer\'s hardware.  2. **Compiler** - It is also known Language processor. 3. **Compiler** - It is a translator program that transform an entire program composed of high/mid-level language statement into an object program consisting of machine language executable code. 4. **Assembler** - It is language translator programs that transform assembly language to machine language instruction. 5. **Interpreter** - It is language translator the process the source program on a statement-by-statement basis and translate high/mid-level language statement and then executes it one at a time. 6. **Linker** - A program for high, mid and low levels of programming language that completes the process by converting the object into executable machine code. 7. **Comment** - It is used throughout a program to improve readability and clarity. 8. **Directives** - These are statement that give information to the assembler. Sometimes directives are called pseudo-ops. 9. **Operators** - These are used at Assembly time to affect the value of an operand. 10. **Pre-defined symbols** - These are the symbols that returns information to your program 11. **Variables** - This is a user- defined name or variable 12. **Name** - It refers to the address of a data item 13. **Label** - It refers to the address of the Instruction or procedure 14. **Title** - Create a title up 60 characters of a source listing. 15. **Dosseg** - Tells the Assembler to ignore all other request and adopt the DOS segment sequence-stack, data and mode 16. **Model** - It specifies and initializes the memory model before defining any segment. 17. **Small** - One Code Segment and one Data Segment. 18. **Large** - One data Segment of 64k and multiple code segments 19. **Compact** - One code segment of 64k and multiple data segment 20. **Stack** - It defines the size of the stack, default stack size is 1,024 bytes 21. **DATA** - It defines and marks the beginning of the data segment 22. **Code** - It defines and marks the code segment which consists of a set of instructions. 23. **END** - It is placed at the last line of the source program 24. **DB** - 8-BIT INTEGER 25. **FWORD** - 48-bit integer 26. **String** - It is used for descriptive data such as person's name or simply a message. 27. **Numeric Constant** - It is defined with a radix specifier such as d for decimal and, b for binary and h for hexadecimal. 28. **MUL** - To multiply of a given register and AX register and store the result to AX register. If the product is greater than 16 bits, the overflow is store in DX 29. **MOV** - Copied and transfer data between to registers or between an immediate 30. **Carry Flag** - The \_\_ records whether certain instructions produced an unsigned number which was too big to be held in the specified register or memory location 31. **Data register** - Four 32-bit data register are used for arithmetic, logical, and other operations 32. **Shift-left-Instructions** - It performs a left shift on the destination's operand, filling the lowest bit with 0. 33. **SAL** - It is identical to the SHL instruction 34. **REN** - In DOS commands, let you change the name of your file. 35. **MD** - This command creates a sub directory using the name you provide preferably eight(8) characters long and must start with a letter. 36. **RD** - This DOS commands let you removes a specific subdirectory. 37. **DIR** - This DOS command let you list all the content of a directory. 38. **A** - This debug command allows you to create a program in mnemonic or symbolic code 39. **U** - This debug command list all the instructions contained in the program beginning at the given address. 40. **D** - This debug command displays the content of a portion memory in hex and ASCII forms starting with the given address 41. **R** - This debug command allows you to display all register and their values. 42. **TLINK** - It is a linker that takes object file(s), libraries etc and combines them together and emits an executable program (in this case an MS-DOS EXE program). 43. **MOV AH, 01H** - Request for character input 44. **INT 21H** - Call Interrupt Service 45. **MOV DL, 24H** - Column size 46. **MOV AH, 08h** - Character input without echo 47. **0A** - Line Feed 48. **0D** - Carriage Return 49. **ROL** - This instruction shifts each bit to the left, with the highest bit copied in the Carry flag and into the lowest bit. 50. **LEA** - This instruction places the address specified by its first operand into the register specified by its second operand.
