It manages all the resources that any accessing software element requires from the hardware. Every operating system has one and the most known could be Linux Kernel, which was on the latest updates on Windows 10 in 2020. It is the heart of every operating system and is responsible for making it work. Kernel is a software program that provides communication between the computer hardware and software. We can see how busy the CPU is operating, how fast our hard drives are retrieving data, and many things so we can monitor if everything is working properly internally and how it handles multiple tasks. The operating system also controls how well the CPU performs all the activities. But it not only takes care of external problems. It is the first barrier against hackers, malware, or any malicious threat that could infect your computer systems. It will protect your data and personal information. Also, it manages memory space for the system for better resource allocation. The operating system provides the structure for you to make changes to files and manipulate them, such as moving them to any specific folders, deleting the file, renaming it, or something more specific. It provides the Input and Output control (known as I/O controller, too), and communication with them through drivers without which any of the Input and Output instructions couldn’t be executed. It will work on storage and memory management too for better performance.Īn operating system coordinates all the hardware components and every device that you connect to your PC. It tracks all the activity, so you can execute your work systematically and be processed when needed. The operating system also will know which software is running and interconnect them. The operating system processes many tasks at the same time, and it decides how and where to allocate “the power” of your computer system to perform it. Every hardware and software component needs its operating software to coordinate and work optimally. It ensures the connection between hardware and software, as it is one of the crucial functions that the operating system provides until the system is shut down. That could be visual and interactable with the Graphical User Interface (GUI) or used in a Command Line Interface (CLI), where you can write lines of commands to tell the operating system to execute a task. It provides the interface in different ways for the user to execute programs, applications, or any kind of software.
