The Evolution of Operating Systems
During my research, I stumbled across three key features that I found paramount to the success of modern operating systems: Graphical User Interface (GUI), Virtual Memory Management, and Cloud Integration.
Graphical user interfaces have created a seamless way for users to interact with their devices without having to type instructions directly into a command line. GUIs use icons, windows, and buttons so that users with little to no technical experience can easily navigate through different applications, greatly increasing productivity and user satisfaction.
Virtual memory management allows the ability to interchange data from RAM to the hard disk drive in order to create a perception of a larger memory space. This feature allows the capability to execute bigger programs and multiple tasks at the same time, eliminating the worry of crashing due to low memory capacity.
Cloud integration creates the freedom to link our files across various devices. With applications like Dropbox, Google Drive, and OneDrive files can be synced, allowing anyone to create and edit documents on any connected device at any given time. Using this feature grants users the opportunity to become more efficient and productive without the need for upgraded software.

Internet of Things (IoT) devices typically rely on minimal operating systems to function effectively on limited hardware. Devices such as smart thermostats, environmental sensors, and wearable fitness trackers, usually have small amounts of RAM and storage, which makes lightweight OSes like Contiki-NG ideal. Minimal operating systems are designed to handle essential tasks, like real-time data processing and wireless communication, without the need for large overhead. By prioritizing low power consumption, IoT devices are capable of running on small batteries for months or even years. The design of these devices and their OSes allows for quick boot times, improved stability, and a reduced risk of software bugs. These minimalistic designs make the devices cost effective, energy efficient, and reliable.
Network devices like routers, switches, and firewalls also use minimal operating systems in order to ensure optimal performance. These devices will typically use watered down OS versions of Linux like OpenWrt and VyOs or commercial OSes like VxWorks. The primary focus of these OSes include stability, speed, and security, making the components specialized in network routing, packet filtering, and VPN services. This streamlined approach allows network devices to be faster to boot, maintain high uptimes, and create a smaller attack surface, improving the cybersecurity of a network. These compact OSes make network devices reliable, efficient, and secure.
