19. WHAT IS THE PURPOSE OF CACHE?
 A cache's primary purpose is to increase
data retrieval performance by reducing
the need to access the underlying slower
storage layer. Trading off capacity for
speed, a cache typically stores a subset of
data transiently, in contrast to databases
whose data is usually complete and durable

23. NVME M 2 SSD
 Short for Non-volatile Memory Express, NVMe is a new technology
utilized by some M. 2 drives. This blazing-fast new bus type uses the
PCIe data transfer lanes on the motherboard, similar to modern
graphics cards. By using the PCIe connection, M. 2 drives can reach
speeds of over 4,000MB/s read and write.
 What are M 2 drives used for?
An M. 2 SSD is a small form factor solid-state drive (SSD) tha
is used in internally mounted storage expansion cards. M. 2
SSDs conform to a computer industry specification and are
designed to enable high-performance storage in thin, power
constrained devices, such as ultrabook laptops and tablet
computers.
