Why Use Threads?
Explore why using threads enhances program performance by enabling parallel processing on multiple CPUs and avoiding blocking during slow I/O operations. Learn how threads help share data efficiently within a single address space and improve responsiveness in multi-threaded applications.
We'll cover the following...
Before getting into the details of threads and some of the problems you might have in writing multi-threaded programs, let’s first answer a more simple question. Why should you use threads at all?
As it turns out, there are at least two major reasons you should use threads.
Parallelism
The first is simple: parallelism. Imagine you are writing a program that performs operations on very large arrays, for example, adding two large arrays together, or incrementing the value of each ...
