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

The x86 includes the following instruction:
IMUL op1, op2, immediate
This instruction multiplies op2, which may be either register or memory, by the im-
mediate operand value, and places the result in op1, which must be a register. There is
no other three-operand instruction of this sort in the instruction set. What is the pos-
sible use of such an instruction? (Hint: Consider indexing.)

Write the assembly code to perform the functionality of a "ret" instruction without using return. 1. Write the first instruction required to perform the functionality of a return instruction. Hint: Do not use a 'pop' instruction as that would modify a register or memory which return does not do, but consider what a pop does besides that. 2. Write the second instruction required to perform the functionality of a return instruction. Hint: jmp
This question assumes the machine architecture at the right. Note the stack pointer register, SP, is not part of the register file. SEL is a multiplexor used to select one of the inputs to the ALU.
