Study Notes
Programming Concepts
- Abstraction in Programming: This involves simplifying complex systems by reducing details and focusing on high-level functionalities. An example includes using functions to encapsulate specific tasks rather than detailing every operation internally.
Software Testing
- Purpose of Acceptance Testing: It validates whether a system meets the specified requirements and is ready for deployment. This testing often involves stakeholder involvement to ensure the software aligns with business needs.
Computer Architecture
- ALU Definition: ALU stands for Arithmetic Logic Unit. It is a fundamental component of a computer that performs arithmetic operations (like addition and subtraction) and logic operations (such as AND, OR, and NOT).
Data Management
- Purpose of a Backup: Backups are crucial for data recovery, ensuring that information can be restored in case of loss due to hardware failures, cyberattacks, or accidental deletions.
Formal Language Theory
- Backus-Naur Form Usage: Backus-Naur Form (BNF) is employed to describe the syntax of programming languages through formal notation. It specifies the structure and rules of a language by defining its grammar.
