Explain in detail the advantages and disadvantages of Machine language and Assembly language. Elaborate explanation required.

Machine language is a primitive language. It's a link between computer science and electronics engineering. It's as easy as working a multiplexer and demultiplexer. Any combination of 0s and 1s is created by the instruction and  used for a particular job / event. 
In a simple example, suppose your house's electrical panel has three switches, one for a fan, one for a dim light, and one for a tube light.  0 represents the off state of the switch and vice versa. You can then make 2 ^ 3 = 8 possible states.
000 -> means every thing is off.
001 -> everything off except tubelite.
.

.

100-> everything off except fan.
.

.

.

.

111 -> everything is on.

like wise in computer processors every sequence of 1 & 0 enables or disables many switches to make the job done.

as these codes are directly understandable by circuit itself there is not over head delay of compiler or interpreter or OS.

Advantages:

1. Machine language is light weight.
2. Machine language is faster.
3. Small footprint
4. Low hardware requirements.
5. Battery friendly.
6. Ideal choice for embedded and IoT systems.

Disadvantages:

1. Not human friendly. difficult to understand not human readable.
2. Higher abstraction cannot be achieved.
3. very hard to debug.
4. Not suitable for complex problem solving or making complex programming solutions.

Assembly language:

Assembly language is a low-level programming language. Helps you understand machine language programming languages. Your computer has an assembler that helps you convert assembly code into executable machine code. Assembly language is designed to be used in machine language to understand and further process instructions. Whether it is an operating system or a computer architecture depends primarily on the architecture of the system.

 Assembly language consists primarily of mnemonic processor instructions or data and other instructions or instructions. It is created by compiling the source code of a high-level language such as C or C ++. Assembly language helps you fine-tune your program.

The assembly language helps programmers write human-readable code that is similar to machine language. Machine language is just a series of numbers and is difficult to understand and read. Assembly language helps you have complete control over the tasks your computer performs.

to print "Hello world" in Windows
global  _main
extern  _printf
section .text
_main:
push    message
call    _printf
add     esp, 4
ret
message:
db  'Hello, World!', 10, 0

The advantages are: 

You can run complex jobs more easily. 

Memory efficiency is high because it uses less memory. 

The execution time is short, so the speed is high. 

This is primarily hardware oriented. Fewer instructions are needed to get results.

 Used for important work. No need to track the location. It is a low-level embedded system. 

Disadvantages The drawbacks are:

 It takes a lot of time and effort to write code. 

It's very complicated and difficult to understand. 

It's hard to remember the syntax.

 There is a lack of program portability between different computer architectures.

 Running a long program written in assembly language requires more computer size or memory.
