What is the main advantage of magnetic core memory over semiconductor RAM memory?
The correct option is E Non volatile
Non volatile is the main advantage of magnetic core
memory over semiconductor RAM memory.
Non-volatile memory (NVM) or non-volatile storage is a
type of computer memory that can retrieve stored information even after having
been power cycled. In contrast, volatile memory needs constant power in order
to retain data.
Magnetic-core memory was the predominant form of
random-access computer memory for 20 years between about 1955 and 1975. Such
memory is often just called core memory, or, informally, core.
Core uses tiny magnetic toroids (rings), the cores,
through which wires are threaded to write and read information. Each core
represents one bit of information. The cores can be magnetized in two different
ways (clockwise or counterclockwise) and the bit stored in a core is zero or
one depending on that core's magnetization direction.
