What is the internal storage of second computer generation?

The second generation of computers, which spanned from the late 1950s to the mid-1960s, primarily used magnetic core memory for internal storage. This type of memory allowed for faster data access compared to the vacuum tube technology of the first generation. Additionally, magnetic tapes and magnetic disks began to be used for secondary storage, enabling larger data storage capacities. Overall, the second generation marked a significant improvement in speed, reliability, and efficiency in computer memory.
