What is machine language and assembly language

MACHINE LANGUAGE:-
Machine code is a computer program written in machine language instructions that can be executed directly by a computer's central processing unit (CPU). Each instruction causes the CPU to perform a very specific task, such as a load, a store, a jump, or an ALUoperation on one or more units of data in CPU registersor memory.

Machine code is a strictly numerical language which is intended to run as fast as possible, and may be regarded as the lowest-level representation of a compiled or assembled computer program or as a primitive and hardware-dependent programming language. While it is possible to write programs directly in machine code, it is tedious and error prone to manage individual bits and calculate numerical addresses and constants manually. For this reason, programs are very rarely written directly in machine code in modern contexts, but may be done for low level debugging, program patching (especially when assembler source is not available) and assembly language disassembly

ASSEMBLY LANGUAGE:-

An assembly language (or assembler language),^[1] often abbreviated asm, is any low-level programming language in which there is a very strong correspondence between the program's statements and the architecture's machine codeinstructions.^[2]

Assembly code is converted into executable machine code by a utility programreferred to as an assembler. The conversion process is referred to as assembly, or assembling the source code. Assembly language usually has one statement per machine instruction, but comments and statements that are assembler directives,^[3]macros,^[4][1] and symbolic labels of program and memory locations are often also supported.
