Typically each development platform consists of the following components except compilers and assemblers
The platform development simply means the development of the fundamental software which is vital in making hardware work.
Operating system: This refers to the low-level software that communicates with the hardware so that other programs can be able to run.
System software: This is the software that's designed in order to provide a platform for the other software. Examples include search engines, Microsoft Windows, etc.
Compilers and assemblers:Compliers are sued in converting source code to a machine-level language. Assembler is used in converting assembly code to machine code.
Hardware platform: This is a set of hardware where the software applications are run.
In conclusion, the correct option is Compilers and assemblers.
Entropy is an extensive property of the system entropy change that value of entropy change can be determined for any process between the states whether reversible or not. i have attached the formula to calculate entropy change which is independent of whether the system is reversible or not and can be determined for any process.
