exekveringsprocess

The term *exekveringsprocess* (Dutch for "execution process") refers to the systematic procedure through which a computer or operating system carries out a program or script. This process involves several key stages, beginning with the loading of the program into memory and ending with its termination or completion.

At the start of the execution process, the operating system locates the program in storage, such as a hard drive or SSD, and loads its executable file into the central processing unit’s (CPU) memory. The CPU then fetches and decodes instructions from the program, executing them step-by-step. During this phase, the operating system manages resources like memory allocation, input/output operations, and system calls, ensuring the program runs efficiently without conflicts with other processes.

The execution process may involve dynamic linking, where external libraries or modules are loaded as needed, or static linking, where all required components are bundled into the executable file. Additionally, the operating system handles interruptions, such as user input or hardware signals, to maintain smooth execution.

Once the program reaches its final instruction, the operating system cleans up resources, such as releasing allocated memory and closing files, before terminating the process. Error handling may also occur if the program encounters exceptions or crashes, prompting the system to log errors or terminate the process abruptly.

In modern computing, the execution process is optimized through techniques like multitasking, where multiple programs share CPU time, and virtual memory, which extends available RAM by using disk storage. This ensures efficient resource utilization and responsive system performance. The precise details of the execution process vary depending on the operating system, architecture, and programming language used.
