Rafaassembly language is specific to a particular machine architecture. assembly languages are designed for specific make and model of a microprocessor. it mean that assembly language program written for one processor will not work on a different processor if it is architecturally different. that is why the assembly language program is not portable.
Its analogous to asking a question, what are the drawbacks of being ape?
Programming languages has evolved from machine codes, assembly etc to High level languages to make programming easier for humans. Writting assembly programs for smaller work can grow to many more pages and again, if it is to be debugged, its terrible.
So to avoid all these, high level language can be used, where compilers take care to handle assembly language drawbacks.

Why high level language is slower then assembly language?
Programs written in a high level language might be slower than ones written in Assembly language; but it is not always so, it is very easy to write un-effective programs in Assembly.
What are the examples of low level language?
It are machine code and Assembly.
What is assembly program?
An assembly program is a machine-dependent program written in a low-level symbolic code known as assembly language.
Which program translates an assembly language program into a high-level language?
A High level language is a language like C, Pascal, Fortran. To convert, the easiest way is to use a compiler. A compiler will take the instructions written in a high level language and convert them into machine code which is the specific instruction set for that type of computer. Assembly language is just a human readable form of a machine code which is how the designers of the computer instruction set made it work. A disassembler will show the assembly language from machine code. But the compiler usually includes a lot of optimisations from a the high level language and will not often generate very simple assembly.
What is the historical development of assembly language?
Assembly language was created in the 50's so that way programmers didn't have to program directly in machine code, which required looking up numerous instruction codes in a huge manual. Nowadays, most people don't program in assembly language, or any other low-level language for that matter. We use a high-level language, such as C++ or Java. However, people will program in assembly if optimization is required that a high-level language doesn't support.
