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.
How Computers Work
Understanding the fundamental hardware architecture of computers — CPU, memory, I/O devices, and the bus architecture that connects them.
Instruction Set Architecture: The Bridge Between Hardware and Software
Explore RISC vs CISC, x86 vs ARM, opcodes, operands, and instruction formats that define how CPUs understand your code.
