1. What is the main goal of performance testing? → To measure responsiveness, speed, and stability under various load conditions
2. Which of the following best describes the concept of a 'closure' in programming? → A function that captures and retains variables from its enclosing lexical scope
3. What does CI/CD stand for in modern software development? → Continuous Integration / Continuous Delivery or Deployment
4. What is the time complexity of binary search? → O(log n)
5. What is a transaction in database systems? → A logical unit of work that must be completed entirely or not at all
6. What is normalization in database design? → Organizing data to reduce redundancy and improve integrity
7. What is Inter-Process Communication (IPC)? → Mechanisms that allow processes to exchange data and synchronize actions
8. What is 'cohesion' in software design? → How well elements within a module belong together
9. Which protocol is used to automatically assign IP addresses to devices on a network? → DHCP
10. What is the TCP/IP transport layer responsible for? → End-to-end communication and reliability between applications
11. Which SQL command removes a table and all its data permanently? → DROP
12. Analysis and design document generation is the process of _______. → Reverse engineering
13. What is paging in memory management? → Dividing memory into fixed-size frames and mapping process pages to them
14. What is a linked list? → A linear data structure where each node contains data and a pointer to the next node
