Electrically Erasable Programmable Read Only Memory is erased by applying a voltage, one byte at a time, while the chip stays soldered in place, which is why it is used for settings that must survive a power cut and yet be changed occasionally, such as the configuration data of a…

The 3.5-inch high-density floppy disk, the square plastic diskette with a metal shutter, was formatted to 1.44 MB, and that figure is still asked in computer awareness papers because it anchors the small end of the capacity ladder.

An SSD is built from flash memory, itself a block-erasable form of EEPROM, which traps charge in floating-gate cells.

Dynamic RAM stores each bit as a charge on a very small capacitor, and that charge leaks away in a few milliseconds, so the memory controller has to read and rewrite every cell continuously.

A nibble is half a byte, that is four binary digits, and it matters because one nibble is written as exactly one hexadecimal digit, from 0 to F. That is why memory addresses in hexadecimal are read four bits at a time.

A register is built into the CPU itself and holds the word the arithmetic and logic unit is operating on at that instant, so it is read and written in a single clock cycle.
