What is the effect of a memory leak?
A memory leak reduces the performance of the computer by reducing the amount of available memory. Eventually, in the worst case, too much of the available memory may become allocated and all or part of the system or device stops working correctly, the application fails, or the system slows down vastly due to thrashing.
What is context leak?
Context-related memory leaks in Android Hence, all widgets in an Android app receive Context as a parameter in the constructor, holding a reference to the entire activity of the application. This also includes its View hierarchy and all other resources. Hence, if you leak the context then you will leak memory.
What is the main cause of memory leaks in application?
Holding the references of the object and resources that are no longer needed is the main cause of the memory leaks in android applications. As it is known that the memory for the particular object is allocated within the heap and the object point to certain resources using some object reference.
What is the effect of a memory leak quizlet?
What is the effect of a memory leak? A process claims memory locations but never releases them, reducing the amount of memory available to other processes. This will damage performance, could prevent other processes from starting, and if left unchecked could crash the OS.
Is memory leak a security vulnerability?
There is a memory leak vulnerability in some Huawei products. An authenticated remote attacker may exploit this vulnerability by sending specific message to the affected product. Due to not release the allocated memory properly, successful exploit may cause some service abnormal.
What causes memory leak in Android?
Memory leaks occur when an application allocates memory for an object, but then fails to release the memory when the object is no longer being used. Over time, leaked memory accumulates and results in poor app performance and even crashes.
Which of the following actions can cause memory leak?
Causes of Memory Leaks Using Unwanted Object Reference: These are the object references that are no longer needed. The garbage collector is failed to reclaim the memory because another object still refers to that unwanted object. Using Long-live Static Objects: Using static objects also leads to a memory leak.
Which condition causes memory leak?
In computer science, a memory leak is a type of resource leak that occurs when a computer program incorrectly manages memory allocations in such a way that memory which is no longer needed is not released. A memory leak may also happen when an object is stored in memory but cannot be accessed by the running code.

What is memory leak in computer?
Memory leaks are a class of bugs where the application fails to release memory when no longer needed. Over time, memory leaks affect the performance of both the particular application as well as the operating system. A large leak might result in unacceptable response times due to excessive paging.
