When an OS is loaded into memory, the kernel is loaded first and remains in memory until the OS is shut down. The kernel is the core component of an operating system which acts as an interface between applications, and the data is processed at the hardware level. It serves as the primary interface between the OS and the hardware and aids in the control of devices, networking, file systems, and process and memory management. All other components of the OS rely on the core to supply them with essential services. The kernel is the core component of an operating system for a computer (OS). A shell script is a sequence of system commands that are stored in a file. Shell provides a way to communicate with the OS by either taking the input from the user or the shell script. Handling the output from the operating system.Interpreting the input for the operating system.It is the outermost layer of the OS and manages the interaction between user and operating system by: Now to perform the functions mentioned above, the operating system has two components: Handles memory management and CPU scheduling.Provides a platform for running applications.Here is a list of some important features of operating systems: Job Scheduling: In a multitasking OS where multiple programs run simultaneously, the operating system determines which applications should run in which order and how time should be allocated to each application.This process displays several alerts to the user so that the appropriate action can be taken against any damage caused to the system. It also checks the hardware for any type of damage. Error Detection: From time to time, the operating system checks the system for any external threat or malicious software activity.Displaying messages related to system vulnerabilities.Protecting the system memory against malicious access.

Protection against intrusion by keeping Firefall active.

Protection against unauthorized access through login.

Following security measures are used to protect user data:

Security: The operating system provides various techniques which assure the integrity and confidentiality of user data.

It also maintains the integrity of the data stored in these files, including the file directory structure, by protecting against unauthorized access.

File Management: An operating system keeps track of information regarding the creation, deletion, transfer, copy, and storage of files in an organized way.

It receives the requests from these devices, performs a specific task, and communicates back to the requesting process. An OS controls the working of these input-output devices.

Device Management: There are various input and output devices.

Memory Management: An operating system manages the allocation and deallocation of the memory to various processes and ensures that the other process does not consume the memory allocated to one process.

Processor Management: An operating system manages the processor’s work by allocating various jobs to it and ensuring that each process receives enough time from the processor to function properly.
