Study Notes

Importance of Programming Languages

Programming languages serve as a formal set of instructions for computers, acting as a bridge between human language and binary code.

Early Programming Languages (1940s-1950s)

Machine Code: The lowest-level language, consisting of binary code directly executed by the CPU, essential for software operation.
Assembly Language (1949): A low-level language using mnemonic codes; still relevant in certain applications like flight simulators.
FORTRAN (1957): Developed by John Backus and IBM, it's the first official programming language, used in NASA's Voyager probes.
COBOL (1959): Created by Dr. Grace Hopper, it became widely used in business, with 80% of US businesses relying on it by 1997.
ALGOL: A family of imperative programming languages established in the late 1950s by a European-American committee.
BASIC (1964): Designed by John G. Kemeny and Thomas E. Kurtz to simplify programming education, aiming to democratize computing.

The Rise of Structured Programming (1960s)

Pascal (1970): Developed by Niklaus Wirth primarily for teaching programming and promoting good practices.
C (1972): Created by Dennis Ritchie, fundamental for operating systems and web development, deemed the mother of high-level languages.

Object-Oriented Programming (1980s)

Smalltalk (1980): An early object-oriented language developed at Xerox PARC under Alan Kay's leadership.
C++ (1985): An object-oriented extension of C, known for speed; coincided with the birth of the internet in 1983.

The Internet and Scripting Languages (1990s)

Python (1991): A popular, easy-to-learn language utilized in web development, machine learning, and IoT.
Java (1995): Developed by James Gosling at Sun Microsystems, a high-level language with minimal implementation dependencies.
JavaScript (1995): Created by Brendan Eich in 10 days, it initially had different names; it is dynamic and high-level but unrelated to Java.
PHP (1995): An open-source server-side scripting language suited for web development, emerged from Rasmus Lerdorf's work in 1994.

Modern Languages and Frameworks (2000s)

C# (2000): Developed by Microsoft, combines elements from C, C++, and Java for versatile applications.
Ruby on Rails (2005): A framework for web applications created by David Heinemeier Hansson to simplify and speed up development.

Modern Trends (2010s)

Swift (2014): Developed by Apple for iOS and macOS applications, focuses on cross-platform mobile development.
Kotlin (2011): Statically typed language that runs on JVM, created by JetBrains, also applicable for JavaScript and native code.

Current Trends and Future Directions

Functional Programming: Rise of languages like Haskell and Scala, emphasizing immutable data and first-class functions.
Languages for Data Science: Python, R, and Julia feature libraries for data analysis and manipulation.
Quantum Computing Languages: Q# by Microsoft and Qiskit by IBM handle quantum algorithms effectively.

Types of Programming Languages

Low-Level Languages:
- Machine Language: Directly understood by the CPU, it's tedious and not portable.
- Assembly Language: Uses mnemonics to simplify machine language; still specific to certain architectures.
High-Level Languages: More user-friendly and closer to natural language, they facilitate easier programming.
- Procedural Languages: Follow a sequence of steps for problem-solving.
- Object-Oriented Languages: Focus on interactions between objects, aiding in data security and modeling real-world concepts (e.g., Java, C#).
