A tool used to test and debug programs, allowing the programmer to execute and inspect the code in a controlled environment.

"Debuggers help identify and correct errors in the code by allowing step-by-step execution and examination of variable values."

a type of cyber attack where multiple compromised computer systems attack a target, such as a server, website, or other network resource, causing a denial of service for users of the targeted resource.

"A DDoS attack can overwhelm the targeted server with requests, making the website or service unavailable to legitimate users."

"The semaphore prevented multiple threads from accessing the critical section simultaneously."

The operation of accessing the data referred to by a pointer or reference.

"Dereferencing a null pointer in C or C++ results in undefined behavior, often leading to a program crash."

In programming, the process of breaking down a complex problem or function into smaller, more manageable parts, often to improve readability or reusability.

"Refactoring code by factoring out common functionality into separate functions can make the code cleaner and less prone to errors."
