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.
Memory management (also dynamic memory management, dynamic storage allocation, or dynamic memory allocation) is a form of resource management applied to computer memory.The essential requirement of memory management is to provide ways to dynamically allocate portions of memory to programs at their request, and free it for reuse when no longer needed.
This is a category of articles relating to software which can be freely used, copied, studied, modified, and redistributed by everyone that obtains a copy: "free software" or "open source software". Typically, this means software which is distributed with a free software license , and whose source code is available to anyone who receives a copy ...
Other languages, such as C and C++, were designed for use with manual memory management, but have garbage-collected implementations available. Some languages, like Ada, Modula-3, and C++/CLI, allow both garbage collection and manual memory management to co-exist in the same application by using separate heaps for collected and manually managed ...
It competed with Quarterdeck's QEMM memory manager. It was manufactured by Qualitas. BlueMax was a special version designed for the IBM PS/2 with ROM compression to get the most of the Upper Memory Blocks. In 2022, the source code was made available on GitHub, and released under the GNU GPL v3 license by Bob Smith of Sudley Place Software. [2]
This category covers software which manages the access and allocation of main memory. This includes real memory and the subcategory for virtual memory . The main article for this category is Memory management .
Software that provides special memory management services for an application, especially for high performance, debugging, or to add garbage collection. Typically a library or part of a language run-time.
