Resource Management[1]
A system resource is any usable part of a computer that can be controlled and assigned by the operating system so all of the hardware and software on the computer can work together as designed. System resources can be used by users, like you, when you open programs and apps, as well as by services which are usually started automatically your operating system. Note: A system resource is sometimes called hardware resource, computer resource, or just resource.[2]
What would the consequences be if we limited...[edit]
| Resource | Description | Consequence of limiting... |
|---|---|---|
| Primary memory | Please read this article about Primary memory. | foo |
| Persistent storage | Please read this article about Persistent storage | foo |
| CPU | When the OS runs a piece of software it has to find the program files on the storage drive, load them into main memory, and instruct the CPU to start executing the program from the beginning.

| Network | Bandwidth, which is the amount of data that can be transmitted in a fixed amount of time, is expressed in multiples of bits per second in digital devices. In analog devices, it is expressed in hertz. A "bus" with low bandwidth can hamper a fast hard drive. The operating system allocates bandwidth to each program, input or output method. | foo |
| Display server | A display server or window server is a program whose primary task is to coordinate the input and output of its clients to and from the rest of the operating system, the hardware, and each other[4]. The IB might call this screen resolution.

| File system | In computing, a file system or filesystem (often abbreviated to fs), controls how data is stored and retrieved. Without a file system, data placed in a storage medium would be one large body of data with no way to tell where one piece of data stops and the next begins. By separating the data into pieces and giving each piece a name, the data is easily isolated and identified. Taking its name from the way paper-based data management system is named, each group of data is called a "file". The structure and logic rules used to manage the groups of data and their names is called a "file system".[5] | foo |
| Sound server | A sound server is software that manages the use of and access to audio devices (usually a sound card). It commonly runs as a background process.[6]
