High Level Languages (HLL)

Overview

High-Level Languages (HLL) play a crucial role in computer programming by providing a more intuitive and readable syntax for developers, ultimately enhancing problem-solving skills. It is essential to understand the classification of HLL to effectively utilize their unique features. These languages can be categorized into various types such as Scientific, General Purpose, Business-Oriented, Procedural, Artificial Intelligence, Scripting, and more. Each classification serves specific purposes, catering to various programming needs.

The characteristics of High-Level Programming Languages set them apart from low-level languages due to their user-friendly nature. HLLs require translation into machine language through interpreters or compilers, making them portable across different platforms. Moreover, their syntax is designed to be easier to read, write, and maintain, resembling English commands. These languages incorporate data types, data structures, selection statements, logical operators, and built-in functions, simplifying the coding process for programmers.

One of the key aspects of HLL is the presence of translators, which facilitate the conversion of human-readable code into machine-understandable instructions. Translators come in two basic types: interpreters and compilers. Interpreters execute code line by line, translating and running it simultaneously, while compilers convert the entire code into machine language before execution. Understanding the role of translators is fundamental in comprehending how HLLs are processed and executed within a computing environment.

Objectives

  1. Classify High-Level Programming Languages Into
  2. Define Translators And Its Two Basic Types
  3. Explain The Characteristics Of High-Level Programmes Languages

Lesson Note

High-Level Programming Languages (HLLs) are programming languages that are designed to be easy for humans to understand and write. They enable programmers to develop complex applications efficiently. Unlike low-level programming languages, high-level languages abstract away most of the hardware-specific details, allowing developers to focus more on the logic of the solution rather than on the minutiae of the computer's operations.
