The Memory Address Register (MAR) is a CPU register that holds the memory address of the data that needs to be accessed or manipulated. When the CPU needs to read from or write to memory, it places the memory address in the MAR.

Physical design in the context of computing typically refers to the actual hardware implementation of a system, including components like processors, memory modules, and peripheral devices, and how they are interconnected on a physical level. Logical design, on the other hand, focuses on the conceptual organization and functionality of a system, often represented through diagrams or models, without concern for the physical implementation details.

1. Flag register is a small storage area within the CPU that holds various binary flags.

2. The Memory Address Register (MAR) is a crucial component within a computer’s processor .It is a register that maintains memory locations these locations represent where the next piece of data or instruction will be read from or written to during processing cycles.

3. Logical design focuses on the conceptual and abstract aspects of a system and Physical design deals with the actual implementation of the system.

Subject

2.To stores the memory address from which data will be fetched or to which data will be stored.

3.-Logical design focuses on the conceptual structure and organization of a system or database.

-Physical design deals with the actual implementation of the system or database on physical hardware.

1.indicator CPU status

2.CPUs possess memory addresses of data that must be fetched and stored from or to the main memory.

3.Logical design is a high-level design and doesn't provide any detail. Physical design is more graphical than textual.

2.A register that holds the memory address of the data. It also help cpu to fetch instructions from memory for execution.

3. 
   

   Logical- Design for how software or system should function based on business requirement

Physical- Setting up hardware and i. nfrastructure such as computer,cooling,wire and more

1. The flags register contains the current state of a CPU. The size and meaning of the flag bits are architecture dependent.

2. The memory addrrss register is the CPU register that stores the memory address from which data will he sent and stored via system bus.

3. Logical design is a high level design and doesnt provide any details. It is more graphical than textual.

2) Memory Address Register (MAR) used to process by providing the necessary address bits to the memory location for decoding.

3)Physical design= Hardware. Encompasses all physical aspects of computer systems, etc. motherboard, keyboard, monitor

Logical design = Software. Logical aspects of system implementation as seen by the programmer, etc. data types, instructions

2. In a computer , the memory address register is the CPU register that either stores the memory address from which data will be fetched to the CPU registers, or the address to which data will be sent and stored via system bus.

3. Logical design is a high-level design and doesn't provide any detail.Physical design is more graphical than textual

1. 8 bits CPU of 8085 microprocessor.

2. In a computer, the memory address register is the CPU register that either stores the memory address from which data will be fetched to the CPU registers, or the address to which data will be sent and stored via system bus.

3. Logical design is a high-level design and doesn't provide any detail. Physical design is more graphical than textual; however, it can comprise both. Logical design can be textual, graphic, or both. A physical design focuses on specific solutions explaining how they are assembled or configured.
