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.

Determine which bits in a 32-bit address are used for selecting the byte (B), selecting the word (W), indexing the cache (I), and the cache tag (T), for each of the following caches: B. 256-line, fully-associative, write back, 16 byte line
How many total bits are required for a direct-mapped cache with 64 KiB of data and 4-word blocks, assuming a 32-bit address? (Note: KiB means 21° Bytes, 1 word is 4 Bytes). Show your whi A work.
i need the answer quickly
A cache is organized as a 4 way set associative cache Each set's cache line consists of 4 words (meaning there are 16 bytes per line, for each set of the cache). Each set individually has one Valid bit, and one Dirty bit, for each line. The tag field of this cache is 8 bits wide. The address is 32 bits wide. Question 1a) What is the number of cache lines? Question 1b) What is the total number of 'memory bitcells' that are needed to design this cache (note, this includes the bitcells required for the tags, valid and dirty bits).
