What primary storage was used in the first generation computers?
Many different types of memory were used in first generation computers, a few of the most commonly used were:electrostatic cathode ray tubes (DRAM)sonic delay lines (DSAM)electrostatic selectron tubes (SRAM)magnetic drums (NVSSAM)magnetic disks (NVSSAM)magnetic core stacks (NVSRAM)Magnetic core memory eventually became dominate.Second and third generation computers continued to use sonic delay line memory, magnetic disk memory, and magnetic core memory (with magnetic core memory still dominating).Late in the third generation computers solid state memory chips replaced all other types of memory.Fourth generation computers used only solid state memory chips.
