geheugenkern
A geheugenkern, also known as a memory core, is a type of non-volatile memory used in early computers. It was developed by Jay Forrester at MIT in the late 1940s and was one of the first forms of random-access memory (RAM). Memory cores are made of a small ferrite toroid, which can be magnetized in one of two directions to represent a binary 0 or 1. This makes them non-volatile, meaning they retain their state even when power is removed.
The basic structure of a memory core consists of a doughnut-shaped ferrite ring with a wire wound
Memory cores were widely used in mainframe computers and minicomputers in the 1950s and 1960s. They were
