High-Level Languages (HLLs) are programming languages that provide a strong abstraction from the details of the computer's hardware. They are designed to be easy for humans to read and write, allowing developers to focus on problem-solving rather than low-level machine code. Examples of HLLs include Python, Java, and C++. These languages often come with powerful features such as automatic memory management and rich libraries, which help streamline the development process. By using HLLs, programmers can create complex applications more efficiently, making them essential tools in modern software development and computer science education.
