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.

The answer is true, even if the time it takes to execute pipeline instructions is not spread uniformly. Where have the problems in this situation been identified?
For example, suppose an instruction is not accepted and VA page 30 is generated. For the following use cases, a TLB controlled by software might be preferable than one handled by hardware:
Using the diagram, what would be the paths.
Because of this, the means by which one instruction acquires its input data are independent of the means by which another acquires its data. When used with a(n): A Combining sets of data with sets of instructions B An example of "multiple data, multiple instruction" C D is for "data alone," meaning there is just one instruction. One order, several results
For example, suppose an instruction is not accepted and VA page 30 is generated. For the following use cases, a TLB controlled by software might be preferable than one handled by hardware:
Fill in the following table showing the results of the indicated instructions, using the register values shown. Also, show the OF and CF values AFTER the instruction executes. Show all results in hexadecimal. Show OF and CF as 0 or 1.

An 'instruction fetch/read' results in three sets of numbers that go to the Registers Block as studied in class. These three numbers in the instruction represent bits 25-21 for 'Read Register 1', bits 20-16 for 'Read Register 2', and bits 15-11 for the 'Write Register'. What does the 5 bits width of each of these indicate? a. That the word is 15 bits long in this architecture b. That each word is 32 bits long c. That there are 32 registers that can be addressed in this architecture d. That there are 15 registers that can be addressed in this architecture
