1. What is a flag register?

2. Explain about Memory address register

3. Differentiate between physical and logical design

# data[].attributes.body
A flag register is a special-purpose register within a computer's central processing unit (CPU) that stores status flags indicating the outcome of arithmetic and logic operations.

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. A flag register indicates CPU states.

2. Memory address register receives address of an instruction from program counter and puts the address on the address bus.

3. Physical design is the layout of hardware in computers, while logical design is how the hardwares work together and their functions.

1. Flag register is the status register that contains the current stage of an x86 CPU.

2. Memory Addreas Register is the CPU register that either stores the memory addreas from which data will be fetch to the CPU registers.

3. logical design is a high level design and doesn't provide any details, whereas physical design is more graphical than textual.

# data[].attributes.body
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.

1. Flag register is a special register. The flag register bits operate independently and their combined value has no meaning

2. The Memory address register is also known as the ‘MAR’ as 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 out by the system bus.

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

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.

1. Indicator of condition of microprocessor and operation.

2. The memory address register is used to handle the address transferred to the memory unit.

3. -Physical aspects of computer systems

-Logical aspects of system implementation as seen by

1. Flags register is a special register in computer processors that stores the status of the arithmetic and logical operations performed by the CPU.

2. The Memory Address Register holds memory address. When the CPU needs to read from or write to memory, it places the address of desired memory location in to memory address register.

3. Physical design refers to actual implementation of system such as hardware, software, and architectural constraints. Logical design focuses on the conceptual structure and functionality of system.

1) Flags register is a special register. Example flags: CF (Carry Flags), OF(Overflow Flags), ZF(Zero Flags).

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

1. The flag register is a special register. It is an 8-bit, 16-bit, or 32-bit register and does not make any sense as a unit.

2. In computing, a memory address is a reference to a specific memory location used at various level by software and hardware.

3. Physical CPU correlates to the actual Physical Cores present on a processor. In the above diagram there are 4 Physical Cores present on the Single Processor. Logical CPU intern refers to the ability of each core doing 2 or more tasks simultaneously.
