Weak references allow an object to be referenced without preventing its garbage collection, which is useful for caching and avoiding memory leaks in programming. They are particularly valuable in scenarios where you want the object to be eligible for garbage collection when there are no strong references pointing to it, thus optimizing memory usage.

Garbage collection is an automatic memory management feature that reclaims memory occupied by objects no longer in use by a program, preventing memory leaks and optimizing resource utilization. It abstracts the complexity of manual memory management, allowing developers to focus on core functionality rather than memory allocation and deallocation.

Caching is a technique used to store frequently accessed data in a temporary storage location to improve data retrieval speeds and reduce latency. It optimizes performance by minimizing the need to access slower, more resource-intensive storage layers, thereby enhancing overall system efficiency.

Memory leaks occur when a computer program incorrectly manages memory allocations, leading to a situation where memory that is no longer needed is not released. This can cause a program to consume increasing amounts of memory, potentially degrading system performance or causing the program to crash.

Programming is the process of designing and building executable computer software to accomplish a specific task or solve a particular problem. It involves writing code in various programming languages, understanding algorithms, and applying logical thinking to create efficient and effective solutions.

Strong references are a type of reference in programming that prevent the garbage collector from reclaiming the memory of an object, ensuring the object remains accessible as long as the reference exists. This is crucial for managing memory efficiently in applications, as it directly influences the lifecycle and availability of objects.

Memory usage refers to the amount of memory a program or system consumes during its execution, impacting performance and resource availability. Efficient memory management is crucial for optimizing system performance, preventing memory leaks, and ensuring applications run smoothly without exhausting system resources.
