Building a Simple CPU Simulator: Implementing the Fetch-Decode-Execute Cycle
Implement a functional CPU simulator in Python that demonstrates the fetch-decode-execute cycle, register file, ALU operations, and memory access.
Deadlock & Starvation
Deadlock conditions (Coffman), prevention strategies, detection & recovery
Device Drivers Architecture
Explore character vs block devices, driver layers, and kernel vs user mode drivers in modern operating systems.
Directory Implementation
How file systems implement directories through linear search, hash tables, and B-trees, enabling efficient path resolution and file lookup operations.
Disk Structure & Layout
Exploring how physical storage is organized through CHS addressing, LBA, disk geometry, and partition schemes like MBR and GPT.
Distributed Operating Systems
Explore distributed file systems, RPC mechanisms, cluster scheduling, and the fundamental concepts behind modern distributed operating systems.
DMA (Direct Memory Access)
Learn how DMA bypasses the CPU for device-memory transfers, DMA buffers, scatter-gather I/O, and IOMMU security.
File Allocation Methods
Understanding how file systems allocate disk space through contiguous, linked, and indexed allocation strategies, and how modern file systems like FAT, ext2/3/4, and NTFS implement these methods.
File System Abstraction
Understanding how operating systems organize and manage files through abstraction layers, from physical storage to logical file operations.
