Study Notes

Classification of Programming Languages

Categories include low-level and high-level languages.
High-level languages are hardware-independent and more portable.
Low-level languages are closer to machine code and provide less abstraction.

Differences Between Low-Level and High-Level Languages

High-Level Languages:
- Use a compiler or interpreter for translation.
- One statement corresponds to multiple machine code instructions.
- Easier to learn and more intuitive due to resemblance to natural language and mathematics.
Low-Level Languages:
- Assembly language translates one statement into one machine code instruction via an assembler.
- Machine code is executable binary, unique to each processor's instruction set.

Prevalence of High-Level Languages

Most computer programs are predominantly written in high-level languages for ease of learning and efficiency in programming.

Benefits of High-Level Languages

Facilitate readability, debugging, and maintenance.
Allow for the development of complex assignment statements that closely mirror problem-solving algorithms.
Specialized languages like SQL, HTML, CSS, and JavaScript streamline programming tasks for specific applications.

Characteristics of Low-Level Languages

Machine code is a low-level language, consisting solely of binary and tailored to specific processor types.
Assembly language, also low-level, corresponds directly to machine code and is useful for embedded systems.

Machine Code vs. Assembly Language

Machine code consists of binary numbers executed directly by processors, with unique instruction sets for each type.
Assembly language requires translation to machine code, featuring a direct 1:1 relationship with it.

Role of Processors

Processors are responsible for executing machine code instructions.

Translation Fundamentals

All programming in high-level and assembly languages must be translated into machine code for execution.
Machine code is presented in binary format and is processor-specific.

Advantages and Disadvantages of Language Types

High-Level Language Advantages:
- Simpler to learn, write, and debug.
- High-level constructs cater to specific problems, enhancing rapid development.
Low-Level Language Advantages:
- Code execution is faster and occupies less memory.
- Greater control over specific hardware components allows for detailed manipulation.

Types of Program Translators

Three common types are interpreters, compilers, and assemblers.
Interpreters: Execute code without generating machine code directly, performing operations via machine code subroutines.
Compilers and Assemblers: Translate input directly into machine code.

Appropriate Use of Translators

Understanding when to utilize each translator type (interpreter vs. compiler vs. assembler) is crucial for effective programming.
