DUSB Flash drive

Answer:

Solid State Drive (SSD) does not belong to the class of primary memory.
It is a type of secondary memory or storage.
Primary Memory (also known as main memory) is directly accessible by the computer's CPU.
It's used for temporarily holding data and program instructions that the CPU is actively using.
It is typically faster but has a lower storage capacity and is more expensive per gigabyte than secondary memory.
