The Architecture of Computing: An Analysis of Operating Systems (E107)

The following essay explores the core concepts typically covered in such a module, focusing on how operating systems act as the bridge between hardware and the user. The Architecture of Computing: An Analysis of Operating

At the heart of any OS is the . This is the first program loaded on startup and remains in memory to manage communication between the hardware (CPU, RAM, and Disk) and the software applications. The E107 curriculum typically highlights how the kernel handles "system calls," which are requests from programs to use hardware resources. This abstraction allows developers to write code without needing to know the specific electrical signals required by every different brand of hard drive or monitor. 2. Process and Memory Management The E107 curriculum typically highlights how the kernel

Through techniques like Virtual Memory , the OS can trick software into thinking it has more RAM than it actually does by using space on the hard drive. This ensures that heavy tasks, like editing a 720p video (similar to the file in question), can run smoothly even on modest hardware. 3. The User Interface and File System The User Interface and File System
