It will also discuss the increasingly powerful methods of machine learning and artificial intelligence to permit more advanced interactions between the user and the system. Finally, it will explore the implications of understanding how an operating system is able to listen and respond to the commands it is issued. By the end of this article, you will have a better understanding of the role of language processing in operating systems.


An operating system (OS) is the most important program that runs on a computer. It manages the hardware and provides services for other programs. Its main job is to provide a platform or environment for other software to run on top of it. It enables applications to interact with the hardware, process data, and manage memory and other resources.
Operating System: A software program that manages the resources of a computer, including memory, processes, and hardware devices. It also provides an interface for users and application programs to interact with the computer.
Platform: The underlying hardware and software environment that allows other programs to function. This includes the processor, memory, and motherboard of a computer.
Services: These are services that an OS provides to programs in order to make it easier for them to interact with the hardware of the computer. Examples of services include the file system, device drivers, networking, and memory management.
Programs: Programs are instructions given to a computer in order to perform a specific task. An operating system is a program that is essential for other software programs to run.
User Interface: A user interface is the graphical and/or command line interface through which the user interacts with the computer. This can be either a graphical user interface (GUI) or a command line interface (CLI).
Memory Management: Memory management is the process of managing available memory, so programs can use the most efficient amount of memory possible. It attempts to meet the needs of all running programs, while not overusing the limited amount of installed RAM.
Hardware Devices: Any type of device connected to a computer that is used to provide input or receive output from the computer. Examples of hardware devices include keyboards, printers, monitors, scanners, and USB devices.

1. Overview of Operating Systems

An operating system understands a language through the use of a compiler, interpretor or translator. Compilers translate programming code, written in a high-level language, into low-level machine language that a computer can execute directly. An interpretor reads each line of code in a program and translates it into instructions that the computer can execute. Finally, translators are tools that can convert one programming language into code in another language.


A compiler is a program that translates source code written in a programming language into machine code that will be used by a computer to execute instructions. A compiler reads in the source code and produces an assembly language, object, or executable code as output. The output can then be executed by the computer, allowing the programmer to use the language on the operating system. The compiler also performs other tasks, such as error-checking and checking for compatibility with the operating system.


An interpretor is a type of software that reads a line of code written in a programming language and translates it into instructions that the computer can execute. Unlike compilers, interpretors don’t translate the entire program at once; they run the code line-by-line, translating it as it goes. As such, it can be used to debug and modify code more quickly than a compiler, but the interpreted code can be slower and require more memory than code compiled by a compiler.


A translator is a type of tool used to convert source code written in one programming language into another programming language. This is useful when a program needs to be run on an operating system that is not compatible with the language in which the program was originally written. Translators can be used to convert popular languages such as Java and C++ into language that can be used on a different operating system.

  • Compilers translate programming code into low-level machine language
  • Interpretors read each line of code and translate it into instructions for a computer
  • Translators are tools which convert one programming language into another

2. Understanding Natural Languages

Do not use any borrowed information
Natural language processing (NLP) is an area of computer science and artificial intelligence concerned with enabling machines to understand and process natural language, or speech spoken by humans in everyday life. The ultimate goal of NLP is to enable machines to interpret and interact in natural language as a human-level intelligence, or “conversational AI”.
NLP typically combines natural language understanding, natural language generation, and natural language interaction — popularly referred to as dialogue systems — in order to create a sense of “understanding” between machines and humans. This understanding is called natural language understanding, or NLU.
In order to enable machines to understand a human language, the language is first broken down into its component parts. This process is called parsing. Parsing involves identifying the parts of speech (nouns, verbs, adjectives, adverbs, etc.) and the relationships between them. This enables machines to determine the meaning of each word or phrase and understand the context in which they appear.
Once the language has been parsed, machines are then able to process the information and generate a response. This response is generated by using natural language generation, or NLG. NLG involves determining the appropriate words and phrases to use in order to create a response that is appropriate for the given situation. NLG employs techniques such as machine learning, decision trees, and rule-based systems to generate the most appropriate response.
Finally, natural language interaction, or NLI, allows machines to interact with humans in natural language. NLI involves understanding a human’s conversation and providing a meaningful response. NLI combines the use of machine learning and natural language understanding to create a dialogue between machines and humans. By combining NLU, NLG, and NLI, machines can begin to understand and respond to human conversations.

3. Comparing Natural Languages and Operating Systems

Language is a fascinating concept; the way we communicate with each other and how we interpret others’ meanings can be complex and often confusing. Understanding how an operating system interacts with languages posed a unique challenge to the scientific community. Despite their differences, operating systems share many of the same concepts with natural languages.

Lexicons and Structure

Initial understanding of an unknown language is broken into pieces like pronunciation, structure, and components. Natural language follows a “lexical approach”, containing words that are built upon each other in structure. For example, ‘running’ made up of ‘run’ + ‘ing’. The same occurs in many programming languages, keywords and clauses which form a robust and secure structure without confusion.

Control Flow

Language is used to control everything around us. We use commands to start computer processes and algorithms to detect mistakes. Much like a purpose-oriented language, such as English, the same grammar rules apply. Much like an operating system, our language interprets commands, translating them into something our brains comprehend. Similarly, a computer reads what it is told and follows that instructions, ensuring the commands are coded correctly.
Natural language and operating systems also have their differences. For example, grammatical rules and punctuation which tell one sentence from another, are not needed in operating systems. Furthermore, the instructions are not controlled by a single command, but by multiple strands of code validating and controlling each element.
Overall, natural language and operating systems have many correlations; we use them in our everyday life to work, communicate and understand each other. As the industry advances, more understanding of how languages interact with each other is made. With that understanding, we become better equipped to create user-friendly operating systems, which can interpret and understand the nuances of communication, from both sides.
