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

Both disks and main memory support direct access to any desired
location (page). On average, main memory accesses are faster, of
course. What is the other important difference between the two

The disk idea helps cut down on wasted time due to rotational delay by using staggered addressing.
Because volatile RAM (Random Access Memory) already exists, what's the point of using a slower, less reliable cache memory instead?The electrical components called transistors are used in both random access memory (RAM) and cache memory. To what extent, if at all, can a computer get by with using just one kind of memory to carry out all of its functions?
Both disks and main memory support direct access to any desired location (page). On average, main memory accesses are faster, of course. What is the other important difference between the two (from the perspective of the time required to access a desired page)?
Since cache memory and RAM both use transistors as its fundamental building block, the question arises as to why we need cache memory since we already have RAM (Random Access Memory) as a volatile memory. Is it feasible to use a single kind of memory in the computer for all of its many functions?
The write buffer will return a block to main memory while the CPU submits a cache-unmet request. What may happen next?
Data that has been stored in memory may be retrieved in one of two distinct ways: either sequentially or directly. Why do essential modern devices make use of direct access, and what are the advantages of doing so? How can the data that has been written on a device that only supports the sequential access technique be translated in such a way that it can be read by a device that only supports the direct access method?
By sending a block from the write buffer to main memory, the processor initiates a cache request that is not completed. Next, do this.
Can you explain the pros and cons of storing disk writes in a cache?
The data stored in access memory may be retrieved in one of two ways: sequentially or directly. I don't understand what it is about direct access that makes it so attractive. It is difficult to replace a device that only allows sequential access with one that only allows direct access; therefore, what other possibilities are there?
When the cache cannot handle a request, the CPU sends the data back to main memory through the write buffer. So, what ought to be done here?
Before we can store (save) or retrieve (load) data in and out of the main memory, we need to provide the memory address to the memory control unit. This address uniquely identifies one single location (word or record) of the memory. Suppose this address is placed in Memory Address Register (MAR) prior to each memory access. What is the size of MAR for a 4GB RAM? (RAM is byte- addressable and each word is 2 bytes). Show all the work.
What is the purpose of having cache memory if RAM (Random Access Memory) is based on transistors? Is it even possible to run every program on the same kind of computer memory?
