Not only do collectors differ in whether they are moving or non-moving, they can also be categorized by how they treat the white, grey and black object sets during a collection cycle. The most straightforward approach is the semi-space collector, which dates to 1969. In this moving collector, memory is partitioned into an equally sized "from ...
In computer science, manual memory management refers to the usage of manual instructions by the programmer to identify and deallocate unused objects, or garbage.Up until the mid-1990s, the majority of programming languages used in industry supported manual memory management, though garbage collection has existed since 1959, when it was introduced with Lisp.
Stop-and-copy garbage collection in a Lisp architecture: [1] Memory is divided into working and free memory; new objects are allocated in the former.

In many contexts, including C++, C# and Java, an object is created via special syntax like new typename(). In C++, that provides manual memory management, an object is destroyed via the delete keyword. In C# and Java, with no explicit destruction syntax, the garbage collector destroys unused objects automatically and non-deterministically.

The Boehm–Demers–Weiser garbage collector, often simply known as the Boehm GC or Boehm collector, is a conservative garbage collector for C and C++ [1] developed by Hans Boehm, Alan Demers, and Mark Weiser. [2] [3] Boehm GC is free software distributed under a permissive free software licence similar to the X11 license. The first paper ...
