Systeemoverhead

Systeemoverhead refers to the resources used by a computer system to perform its own operations, rather than executing application tasks. This includes the memory, processing power, and time consumed by the operating system, background processes, and system services. When a system has high overhead, fewer resources are available for the user's programs, potentially leading to slower performance.

Operating systems manage hardware and software, requiring their own set of instructions and data to run. These instructions, along with the processes that manage scheduling, memory allocation, and device interaction, constitute a significant portion of system overhead. Similarly, background services that provide functionalities like networking, security, and system updates also contribute.

The impact of system overhead can be observed in various ways. For example, a computer with a demanding operating system and many running background applications might feel sluggish even when running a simple program. Users can often monitor system overhead through tools like Task Manager on Windows or Activity Monitor on macOS, which display CPU and memory usage by different processes. Optimizing system overhead often involves closing unnecessary applications, disabling non-essential startup programs, and ensuring the operating system and drivers are up to date.
