Detailed explanation-1: -Storage Capacity A ROM chip can store several megabytes (MB) of data, ranging from 4 to 8 MB per chip. A RAM chip, however, can store much more data, ranging from 1 to 256 gigabytes (GB) per chip.
Detailed explanation-2: -RAM has a large size with even higher capacity, whereas ROM is smaller in size and even with lesser capacity. RAM is a high-speed memory with reading-write operations, which happen at a fast pace, whereas ROM is slower speed memory, which is less prone to modification and can be done via an external program.
Detailed explanation-3: -A binary digit is logical 0 and 1 representing a passive or an active state of a component in an electric circuit. A group of 4 bits is called nibble. A group of 8 bits is called byte. A byte is the smallest unit, which can represent a data item or a character.
