System Design and Scalability

~60 min · 15 stations

System Design and Scalability is a self-paced learning path in Computer Science & AI, free to read, written at General Public / 9th Grade reading level. Across 15 structured stations, you will work through the core ideas step by step, each with a short quiz to check your understanding. By the end you will be able to define the fundamental principles of system scalability; describe the basic interaction between clients and servers; differentiate between system latency and network data throughput.
