Magnetic Bubble Memory – MBM (Definition)
The Magnetic Bubble Memory (MBM) is a serial solid state memory device used to store a large amount of data. The data bits are stored in the form of bubbles. The process of electromagnetic induction is used to produce the bubbles in a memory. The capacity of bubble memory is 100 kilo Bytes to Mega Bytes. There are two types of loops are available in the magnetic bubble memory such as Minor and Major loops. All the MCQs on Magnetic Bubble Memory (MBM) Questions and Answers are published according to the new study syllabus for the academic year 2022.
