Study Notes
Core Concepts (Multiple Choice)
- Loop Purpose: A loop repeats a specific block of code.
- Data Structure for Queue: A linked list is best for implementing a queue.
- Transmission Control Protocol (TCP) Function: TCP's primary function is reliable data transfer.
Practical Coding (Programming Exercises)
- Python Even Number Sum Function: A Python function (
sum_of_evens) calculates the sum of even numbers in a list. - SQL Employee Salary Query: An SQL query retrieves employee names whose salary exceeds $50,000. The query uses
SELECT name FROM employees WHERE salary > 50000;
System Design (Essay)
- Microservices vs. Monolithic Architecture: Microservices break an application into independent services, whereas monolithic architecture bundles all components into one codebase.
- Cloud Migration Advantages/Challenges: Cloud migration advantages include scalability and cost-effectiveness. Challenges include security concerns and data transfer costs.
- Scalability Definition: Scalability is a system's ability to handle increased load.
- Scalable Application Strategies: Strategies for a scalable application include load balancing, horizontal scaling, and caching.
