The smallest addressable unit of memory is
Explanation
In computer architecture, the byte is considered the smallest addressable unit of memory. While a bit is the most fundamental unit of information (representing a 0 or a 1), most computer systems are "byte-addressable," meaning the hardware assigns a unique memory address to every 8-bit group (byte) rather than to individual bits.
- Bit: The smallest unit of data, but generally not directly addressable by the CPU.
- Nibble: Consists of 4 bits (half a byte); it is not a standard addressable unit.
- Word: The natural size of data handled by a processor (e.g., 32-bit or 64-bit), which is larger than a byte.
According to standard computer science definitions (and NCERT textbooks), because the CPU accesses memory locations starting at the byte level, the byte is the correct answer.
