Types of database architectures

A Database Architecture represents the Database Management System’s (DBMS) design (schema). The DBMS architecture makes it easy to understand the components involved in the database system and their relations. The DBMS architecture may vary based on the system on which it runs. Some systems contain both client and server machines whereas some run only on a server machine. Based on the architecture, the system can be classified as centralized, decentralized, or hierarchical.

Question

A certain processor deploys a single-level cache.
The cache block size is 16 words and the word
size is 4 bytes. The memory system uses a 100-
MHz clock. To service a cache miss, the
memory controller first takes 1 cycle to accept
the starting address of the block, it then takes 5
cycles to fetch all the sixteen words of the block,
and finally transmits the words of the requested
block at the rate of 2 cycle per word. The
maximum bandwidth for the memory system
when the program running on the processor
issues a series of read operations is
107 bytes/sec.
