Process-Scheduling

Behind the Scenes of Operating Systems: From Kernels to Interfaces Operating systems sit between programs and hardware. They manage memory, schedule tasks, handle input and output, and present a practical interface to software. Think of an OS as a city: the kernel acts as the central planner and service hub, while applications run in their own neighborhoods in user space. The result is a stable, responsive environment for many programs at once. ...

Process Scheduling and Memory Management Think of the operating system as a traffic manager for a computer. It must decide which program runs now and how much memory each program can keep. Two core tasks help the system work well: process scheduling and memory management. Together, they keep programs responsive and safe. Process scheduling focuses on the order and duration of CPU use. The goals are to keep the CPU busy, respond quickly to user actions, and treat programs fairly. The system watches simple ideas like how long a task waits in the ready queue and how often the CPU is idle. ...

From Boot to User Space: A Practical tour of Operating Systems When you turn on a computer, you see a short sequence before applications appear. This path from power on to a usable desktop is called the boot process. It starts with firmware (BIOS or UEFI) that checks hardware and finds a bootloader on storage. The bootloader then loads the kernel into memory and hands control to it. From this moment, the operating system begins its careful dance with hardware. ...
