Study Notes
Low-level Programming Languages
- Machine language consists of binary code (1s and 0s) and is machine-dependent.
- Computers can directly interpret their own machine language without conversion.
Assembly Languages
- Utilize mnemonics (English-like abbreviations) for instructions, making them clearer for humans.
- Requires translation into machine language via assemblers for computer comprehension.
- Example assembly instructions:
load salary,add bonus,store total.
High-level Programming Languages
- Instructions resemble English and mathematical notation, simplifying programming tasks.
- A single statement can accomplish substantial tasks, making it user-friendly.
- High-level languages need translation into machine language by compilers or interpreters.
- Common high-level languages include C, C++, Python, Visual Basic, and Java.
- Example high-level statement:
total = salary + bonus;.
Program Code Translation
- Translators are essential for converting code between languages.
- Assemblers convert assembly language to machine language.
- Compilers convert high-level language to machine language.
- Interpreters translate high-level language to machine language on-the-fly.
Compiling
- Compilation translates the entire source code file into machine code in one go.
- If the source code has syntax errors, the machine code file will not be created; errors must be corrected first.
Software Development Life Cycle
- Involves creating computer programs through various steps, including requirements analysis, design, implementation, and testing.
Role of Software
- Software is a set of instructions to operate a computer and produce specific results.
- Acts as a bridge between users and hardware, facilitating task management and problem-solving.
Steps in Software Design and Testing
- Desk checks and testing with known inputs help ensure algorithms produce correct outputs.
- Review and refine algorithms based on test cases, correcting errors iteratively.
History of Java
- Developed in the early 1990s by Sun Microsystems, designed for simplicity and flexibility.
- Released in 1995, it gained popularity for its cross-platform capabilities and utility in web development.
- Continues to be favored for large business applications and Android development.
How Java Works
- Java source code is written in the Java programming language.
- A Java compiler converts the source code to bytecode, which is machine-independent.
- The bytecode is processed by the Java Virtual Machine (JVM), translating it into native machine code for execution.
- This process ensures that the same Java program can run on any computer with a JVM, enhancing its versatility.
