In addition, encryption may be needed if it’s used for communications between two devices. For example, if a language is being used to control hardware, it needs additional programs that tell it how to process data without human interaction. Other functions vary based on how they’re being used. Most programming languages share these functions as their key characteristics but differ in many ways, such as syntax or library sizes. The main functions of a programming language are to store and manipulate data, control hardware, provide security, and be an understandable medium for humans. What are a programming language’s key functions? Recommended Reading: See compile and interpreter for more information about these two methods. Regardless of what language is used, the program must eventually be converted into machine language so that the computer can understand it. 4GLs are far removed from machine languages and represent the class of computer languages closest to human languages. Lying above high-level languages are languages called fourth-generation languages (usually abbreviated 4GL). Machine languages consist of numbers only. Assembly languages are similar to machine languages, but they are much easier to program in because they allow a programmer to substitute names for numbers. Lying between machine languages and high-level languages are languages called assembly languages. Each different type of CPU has its own unique machine language. High-level programming languages, while simple compared to human languages, are more complex than the languages the computer actually understands, called machine languages.

The process is similar for websites when a user enters text into a search engine like Google, it converts the user’s query into machine code before sending it off to its servers. It then takes any information produced by those commands and translates it back into something humans can understand-usually English.
When a programmer types a command into their computer’s terminal, it sends those instructions to their computer’s processor, which translates them into machine code, so it can execute them. Machine code is a binary format that consists of ones and zeros (1 and 0) each digit represents either an instruction or data within the program.
