OS, Networks and Data Structures Basics

Q: What fundamental OS, networking, and data-structure concepts should you revise before a Zomato technical round? A: OS: process vs thread, scheduling algorithms, deadlock conditions, virtual memory/paging. Networks: the OSI/TCP-IP model layers, how DNS resolution works, HTTP vs HTTPS, TCP handshake. Data Structures: time/space complexity of arrays, linked lists, trees, hash maps, and heaps, and when to choose one over another. Expect rapid-fire conceptual questions across all three areas rather than deep dives into any single topic.
