Study Notes
Compiled Language
- Compiled languages are converted directly into machine code that the processor executes.
- Compiled languages tend to be faster and more efficient than interpreted ones.
- Compiled languages give the developer more control over hardware aspects, such as memory management and CPU usage.
- A "build" step is needed.
- Compiled languages must be manually compiled first.
- Programs must be rebuilt every time a change is made.
Interpreted Language
- Interpreters run through a program line by line, executing each command.
- Interpreted languages were once significantly slower than compiled ones.
- The gap between interpreted and compiled languages speed is shrinking due to just-in-time compilation.
- Examples of common interpreted languages include PHP, Ruby, Python, and JavaScript.
Compiled Programs: Advantages and Disadvantages
- Advantage: Compiled code generally runs faster than interpreted code.
- Disadvantage: Compilation adds time before program testing.
- Disadvantage: Generated binary code is platform-dependent.
Interpreted Language: Advantages and Disadvantages
- Advantage: Tends to be more flexible, often offering features like dynamic typing and smaller program sizes.
- Advantage: Code is platform-independent, as interpreters execute the source program code directly.
- Disadvantage: Execution speed is typically slower compared to compiled languages.
Scripting Languages
- Scripting languages are programming languages where instructions are interpreted individually at runtime.
- Conventional programming languages like C and C++ are compiled in advance and in their entirety.
- Scripting languages are simpler, easier to learn, and quicker to code, but they're not as robust or efficient as conventional languages.
- Scripting languages are a subset of programming languages; therefore, all scripting languages are programming languages, but not all programming languages are scripting languages.
- Scripting languages do not require a compilation step and are interpreted.
- A C program needs compiling before it runs, whereas JavaScript or PHP does not.
- Scripting languages are used for smaller tasks
- Programming languages are generally used to build large and complex software applications, operating systems, and enterprise-level software.
Applications of Scripting Languages
- Automate tasks within a program.
- Extract information from a data set.
- Less code-intensive compared to traditional programming languages.
Programming Language
- This is a computer language used by programmers/developers to communicate with computers.
- A set of instructions written in a specific language (e.g., C, C++, Java, Python) to perform a task.
Applications of Programming Languages
- They typically run inside a parent program like scripts.
- More compatible while integrating code with mathematical models.
- Languages like Java can be compiled and used on any platform.
Scripting Languages: Advantages
- Interactivity: Code can be developed and tested very rapidly due to the nature of the language.
- Accessibility: Scripting languages focus on making common tasks straightforward and intuitive.
- Dynamic Behavior: Scripting languages have dynamic typing, the type of a variable can change at runtime.
Programming Languages: Advantages
- Performance: Compiled code leads to faster execution and efficient resource use.
- Type Safety: Static typing requires variables to be declared with a specific type, catching compile-time errors.
- Scalability: Designed to handle large-scale software systems, with garbage collection, efficient memory management, and optimized data structures.
How Scripting Languages Are Used
- Scripting languages are categorized as server-side or client-side.
- PHP, Ruby, and Python are examples of server-side scripting languages processed on the host server.
- JavaScript, HTML (Hypertext Markup Language), and CSS (Cascading Style Sheets) are examples of client-side scripting languages processed on the user's computer, typically in a browser.
- Client-side scripting reduces server and network loads.
- Server-side scripts are more secure and not visible to the user.
