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]

Resources which needs to be managed[edit]

Resource Description
Primary memory Primary Storage is the area in the computer where data is stored for quick access by the computer's processor. RAM is often synonymous with this term.
Secondary storage foo
processor speed foo
bandwidth 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.
screen resolution Number of distinct pixels in each dimension that can be displayed. It is usually quoted as width × height for example, "1024 × 768."
disk storage Disk storage is a storage mechanism where data is recorded using various methods : Electronic, magnetic, optic or mechanical. Disk storage is stored by a computer processor and communicates within a computer with the use of input and output operations (I/O). Disk storage is managed by the operating system by determining when to read and write from a storage point.
sound processor foo
graphics processor foo
cache Cache memory is a small-sized type of volatile computer memory that provides high-speed data access to a processor and stores frequently used computer programs, applications and data. It is the fastest memory in a computer, and is typically integrated onto the motherboard and directly embedded in the processor or main random access memory (RAM).
Network connectivity foo
