What is Lea vs MOV?
LEA stands for Load Effective Address. It takes the result from address generation, and puts that result directly in a register, without accessing memory. MOV , on the other hand, will move data to or from memory at the computed offset.

LEA means Load Effective Address.27-Jun-2013
What is the difference between offset and Lea?
Also offset ar - is immediate value which is calculated during translation. And lea - is actual processor instruction "Load Effective Address" with second operand which references to memmory.04-Jun-2016
What is the purpose of LEA instruction in 8086?
LEA − Used to load the address of operand into the provided register. LES − Used to load ES register and other provided register from the memory.
Why do we use Lea?
The LEA (Load Effective Address) instruction is a way of obtaining the address which arises from any of the Intel processor's memory addressing modes. it moves the contents of the designated memory location into the target register.
What is Lea when to use it?
lea is an abbreviation of "load effective address". It loads the address of the location reference by the source operand to the destination operand. For instance, you could use it to: lea ebx, [ebx+eax*8] to move ebx pointer eax items further (in a 64-bit/element array) with a single instruction.
What is offset in assembly?
In assembly language In computer engineering and low-level programming (such as assembly language), an offset usually denotes the number of address locations added to a base address in order to get to a specific absolute address.
What is SI in assembly?
SI stands for source index. Source index is use as a pointer to the current character being read in a string instruction(LODS,MOVS, or CMPS). Source index is also available as an offset to add Bx or Bp when doing indirect addressing. example: MOV [Bx + SI] , Ax.28-Sept-2009
What offset flat?
OFFSET would have translated to a segment selector (DS) and OFFSET, whereas OFFSET FLAT translates to an absolute address of the label LC0 relative to 0 (seeing as that's the base of the DS segment in flat mode), which the linker resolves after it is assembled.03-Apr-2020

Effective Address or Offset Address: The offset for a memory operand is called the operand's effective address or EA. It is an unassigned 16 bit number that expresses the operand's distance in bytes from the beginning of the segment in which it resides.
