[2] It was designed to be the first minicomputer with full support for time-sharing in the hardware and the operating system, features that had mostly been limited to mainframes, or retrofitted to existing systems like Digital's PDP-11, on which Unix was implemented.
First HP graphing calculator, and introduced the Forth-like RPL, programmable keys, and symbolic equation solving, with 2 KB of user memory. Book-style design (flip-open cover) with keys on both interior halves. HP-28S: 1988 Expansion of HP-28C; 32 KB of user memory due to customers unexpectedly keeping programs in memory for extended periods ...

MemTest86 and Memtest86+ are memory test software programs designed to test and stress test an x86 architecture computer's random-access memory (RAM) for errors, by writing test patterns to most memory addresses, reading back the data, and comparing for errors. [ 5] Each tries to verify that the RAM will accept and correctly retain arbitrary ...
Memory management 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 critical to any advanced computer system where more than a single process ...
