Multitasking vs. Multithreading: What's the Difference?

Edited by Sawaira Riaz || By Sumera Saeed || Updated on October 15, 2023
Multitasking involves running multiple tasks or processes concurrently, while multithreading splits a single task into smaller threads running in parallel.

Key Differences

Multitasking and multithreading are both techniques used in computing to optimize the execution of tasks. While both deal with concurrent execution, their fundamental principles and applications differ. Multitasking allows multiple tasks or processes to share system resources, enabling the computer to appear as if it's doing several operations simultaneously.

In contrast, multithreading specifically refers to the concurrent execution of multiple threads within a single process. A thread is the smallest unit of CPU execution. Multithreading enhances the efficiency of a program by dividing a process into multiple threads that can run concurrently, leveraging the capabilities of modern multi-core processors.

While multitasking focuses on maximizing the utilization of CPU by switching between different tasks, multithreading aims to improve the throughput and performance of a single application. Multitasking can involve several unrelated applications, such as running a web browser and a word processor at the same time. Multithreading, on the other hand, is about splitting a single application into smaller threads to achieve parallelism within the application itself.

Both multitasking and multithreading have their challenges. With multitasking, there can be resource contention as multiple processes vie for system resources. In multithreading, challenges like thread synchronization, race conditions, and deadlocks can arise. Despite these challenges, both concepts significantly contribute to the efficiency and speed of modern computing systems.
