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.

Please help me with my AlgorithmDesign problem. From the following list of bus rapid transit system (one way): Name Route Vacation A->B->C->D Work 1 E->B->F->G->H Work 2 B->N->E Work 3 H->D->N The problem: ➢ Task: Design an algorithm (C/C++/Java/Phyton) to read the bus rapid transit system routes list and print the number of tickets we need to purchase if we want to visit all places minimal twice. The complexity of the algorithm must be O(V+E). V is the number of places. E-> is the number of transits. ➢ PS: Use Tarjan’s or Kosaraju’s strongly connected component algorithm. **In order for A to be visited twice, we must order 2 "Vacation" tickets (multiply by 2)
Write a code in sim8085 for the following problem: The pressure of two boilers is monitored and controlled by a microcomputer works based on microprocessor programming. A set of 6 readings of first boiler, recorded by six pressure sensors, which are stored in the memory location starting from 2050H. A corresponding set of 6 reading from the second boiler is stored at the memory location starting from 2060H. Each reading from the first set is expected to be higher than the corresponding position in the second set of readings. Write an 8085 sequence to check whether the first set of reading is higher than the second one or not. If all the readings of first set is higher than the second set, store 00 in the ‘D’ register. If any one of the readings is lower than the corresponding reading of second set, stop the process and store FF in the register ‘D’. Data (H): First set: 78, 89, 6A, 80, 90, 85 Second Set:71, 78, 65, 89, 56, 75
Question 3 Multiple Choice: We have been assigned the task of selecting an interface language for a device controller. Two proposals have been made. Method C uses C++ while Method R uses regular expressions. Based on your knowledge of CSE 355, a primary benefit of Method C over Method R is Method C can compute everything that Method R can, and more. O There is an algorithm to analyze Method C to detect infinite loops, but no algorithm for method R. Method C can be represented as a Finite Automaton while Method R cannot. Method C always terminates in fewer computation steps than Method R on the same input.

Example: The Problem Input File Using C programming language write a program that simulates a variant of the Tiny Machine Architecture. In this implementation memory (RAM) is split into Instruction Memory (IM) and Data Memory (DM). Your code must implement the basic instruction set architecture (ISA) of the Tiny Machine Architecture: //IN 5 //OUT 7 //STORE O //IN 5 //OUT 7 //STORE 1 //LOAD O //SUB 1 55 67 30 55 67 1 LOAD 2- ADD 3> STORE 4> SUB 5> IN 6> OUT 7> END 8> JMP 9> SKIPZ 31 10 41 30 //STORE O 67 //OUT 7 11 /LOAD 1 //OUT 7 //END 67 70 Output Specifications Each piece of the architecture must be accurately represented in your code (Instruction Register, Program Counter, Memory Address Registers, Instruction Memory, Data Memory, Memory Data Registers, and Accumulator). Data Memory will be represented by an integer array. Your Program Counter will begin pointing to the first instruction of the program. Your simulator should provide output according to the input file. Along with…
Write a C code which consists of a parent process with two child processes. The parent process will control the execution of both child processes giving them alternatively a specific time after which the executing process will be stopped by the parent and resume the execution of the second child. The body of both children processes consist of print their pids in an infinite loop. Hint use fork and signals.
The hierarchical structure of a computer system is usually divided into a microprogramme machine layer, a machine language layer, an operating system layer, an assembly language machine layer, and a high-level language machine layer. The relationship between levels is ( ).A, the upper and lower levels are irrelevant B, the upper layer to achieve the next layer of functional expansion, and the next layer has nothing to do with the previous layerC. The upper layer realizes the function expansion to the next layer, and the next layer is the foundation of the upper layer. D. The upper layer has nothing to do with the next layer, and the next layer is the foundation of the upper layer.
