A) Non-volatile memory that holds its contents even during power outages.
B) Memory used for high-speed transfer of data.
C) Volatile memory that loses its contents during power outages.
D) Special memory used in portable devices.

Answer 1

Cache memory is a volatile type of memory that loses its contents during power outages and is used to quickly access frequently used data and instructions to improve computer performance.

Step-by-step explanation:

The best description of cache memory is C) Volatile memory that loses its contents during power outages. Cache memory is a type of memory used in computers to enable quick access to data by storing frequently used instructions and data. It is considered volatile because like other types of RAM, it requires power to maintain the information it holds; once power is lost, so is the information. Cache memory is much faster than main memory (RAM), and it improves the efficiency and performance of the computer by reducing the time it takes to access data from the main memory.
