1. In your perspective, is there a possible relationship between the processor and the display quality of your device? Rationalize your answer
2. Operating System, RAM, or Processor. Which among the three would you upgrade first and why?
3. Search for another example of an operating system (aside from the operating systems that are already included in the handout) and examine its architecture and specifications. Then, answer the following items:
   1. What is the name of the operating system? 
   2. What is the latest version of the operating system? 
   3. Who developed the operating system?
   4. Cite your reference(s). 

                                   5. Describe the internal architecture of the operating system.

Plug-and-play manager - This determines which drivers are required to support a particular device and loads those drivers. Power manager - This coordinates the power consumption among various devices. It can be configured to reduce power by shutting down idle devices or the entire system, or setting the processor to sleep. Security reference monitor - This enforces the access validation and audit-generation rules for all protected objects including files, processes, address spaces, and I/O devices. Virtual memory manager - This manages virtual addresses, physical memory, and paging files on a disk. Process/thread manager mana This creates, manages, and deletes processe processes and thread objects. Configuration manager - This is responsible for implementing and managing the system registry, which serves as the repository for both system-wide and per-user settings of various parameters. Advanced local procedure call (ALPC) facility This implements an efficient cross-process call mechanism for communication between local processes implementing services. and subsystems. Windows Kernel - This is considered the core software the OS. It controls the execution of the processors. This manages thread scheduling, process switching, exception and interrupt handling, and multiprocessor synchronization. Note that the Kernel's own code does not run in threads. Hardware abstraction layer (HAL) This isolates the OS from platform-specific hardware variances. It makes each computer's system bus, direct memory access (DMA) controller, interrupt controller, system timers, and memory controller look the same to the Windows Executive and Kernel components. Device drivers - These are dynamic libraries that extend the functionality of the Windows Executive. These include hardware device drivers that translate user I/O function calls into specific hardware device I/O request, and software components for IT2105 implementing file systems, network protocols, and any other system extensions that need to run in kernel-mode. Windowing and graphing system - This implements the graphical user interface (GUI), such as the user interface controls and illustrations.

Special system processes: These include user-mode services such as the session manager, the authentication subsystem, the service manager, and the log-on process. 2. Service processes: These involve services used by both Microsoft and other external software developers to extend system functionality and run background user-mode activity on a Windows system. 3. Environment subsystems: These provide different operating system environments and support Portable Operating System Interface (POSIX) and Win32 subsystems. Each environment subsystem contains processes shared among all applications. 01 Handout 1 student.feedback@sti.edu *Property of STI Page 3 of 5 STI IT2105 User applications: These include executable (EXE) programs and The classic LINLY is equipped with number of user services and 27C Cloudy 4 ENG 11:07 AM 10/5/2021
