Resource allocation - is assigning pre-set amounts of RAM for certain functions. For example, when a computer first boots-up - it allocates a portion of the machine's RAM for Windows to use - even though the actual program doesn't occupy all the computer's memory. It simply holds some 'in reserve'.

Ubuntu is an operating system and it has all typical functions: resource allocation, filesystem and storage management, handling of input and output operations, communication between applications and the hardware.
There are a few key attributes of an operating system. The most common keys are scheduling, memory management and allocation of resources.

The operating system prevents starvation in resource allocation processes by using algorithms that prioritize fairness and ensure that all processes have a chance to access resources, rather than allowing one process to monopolize them indefinitely.

The processor time is a function of the processor. The memory allocation is a function of the operating system.
The "Operating System" or OS
A number of things will prompt efficient resource allocation in a well-functioning market system. The quantity and the price of the commodities are the main aspects.
a resource management system
The unique identifier that distinguishes each resource in an operating system is typically referred to as a "process ID" (PID) for processes or a "resource ID" for other resources. The operating system uses these identifiers to manage the lifecycle of resources, tracking their allocation, monitoring their activity, and facilitating their deallocation. This system ensures that resources are efficiently allocated and released, allowing for the smooth operation of multiple processes. Ultimately, it allows the OS to manage multiple tasks and optimize resource utilization.
In an operating system, accounting refers to the process of tracking and managing resource usage by various processes or users. This includes monitoring CPU time, memory consumption, I/O operations, and other system resources to ensure efficient allocation and utilization. Accounting information helps system administrators understand performance metrics, enforce resource limits, and facilitate billing or chargeback mechanisms for resource usage. Overall, it plays a crucial role in system management and optimization.
An operating system (OS) is an interface between hardware and user which is responsible for the management and coordination of activities and the sharing of the resources of a computer, that acts as a host for computing applications run on the machine. As a host, one of the purposes of an operating system is to handle the resource allocation and access protection of the hardware. This relieves the application programmers from having to manage these details.
