A suoritussäie, often translated as execution thread or simply thread, is a fundamental concept in computer science related to multitasking and concurrency. It represents a single sequence of execution within a process. A process can have multiple threads, allowing it to perform several tasks seemingly simultaneously. Each thread within a process shares the same memory space and resources, such as open files and network connections. This sharing of resources makes threads more lightweight and efficient than separate processes, which have their own independent memory spaces.

Threads are essential for modern software applications that need to remain responsive while performing background operations. For example, a web browser uses multiple threads to download web pages, render content, and handle user input concurrently. Similarly, a word processor might use one thread to handle user typing and another to perform spell checking in the background. Operating systems manage the scheduling of these threads, allocating processor time to them in a way that creates the illusion of simultaneous execution. This allows users to interact with applications without experiencing delays or freezes. The concept of threading is crucial for improving performance and user experience in a wide range of software.
