What is Basic structure of low level language?

Answer 1

Most people only consider the assembly languages (and plain bytecode) to be "low level" languages. Due to this, the "structure" of a low level language is simply a sequence of instructions for the CPU.

Answer 2

the basic unit of a language is a sentence. Sentences have different structures according to their kind. A simple English sentence has the structure=

Subject+verb+object = Bano bought a book.

Answer 3

Assembly languages are low-level languages such that there is a one-to-one correspondence with the architecture's machine code instructions. Since there are no structures or procedures in assembly, code is written in a "spaghetti" style, such that whenever a decision statement is encountered, code will either continue to the next instruction or jump to another section of code entirely. This makes the code extremely difficult to read with verbose user-comments to give the code some sense of structure. The code is essentially divided into two main sections corresponding to the text and data segments of the assembled executable. The text segment contains the actual instruction code while the data segment contains all the named constants and global variables that the text segment can directly refer to (by name). All code is written in terms of the machine, thus there are no high-level abstractions such as function calls (subroutines) or structured loops. In C programming, we can use the C compiler to generate the low-level assembly code from the high-level C source. Examining this code will reveal that even the most trivial of C programs can generate many hundreds of individual assembly instructions. Compiling with the maximum optimisation will render the code virtually unreadable. Reverse engineering low-level code requires a great deal of skill and patience.
