Which register contains the address of the next instruction to be executed? The register that stores the address of the next instruction is called the program counter. Normally, after each instruction is executed, the program counter is incremented by one (hence the use of the word counter), so that it contains the address of the next instruction.
Which contains the address of the next command to be executed? Answer: The program counter (PC), which contains the address in memory of the next instruction to be executed.
Used to hold the statement that is being executed? A register that stores the current instruction while it is being executed is called an instruction register.
Which plant gives 24 hours oxygen?Which register always contains the top address of the stack? The stack pointer register contains the address of the top of the stack. And the program counter is a register that always contains the address of the memory location from which the next instruction needs to be fetched for execution.
Which register contains the address of the next instruction to be executed? – Related questions
What is a command register?
(1) Command Register (CR): The Command Register is used by the host processor to control the RU unit. The host processor requests the RLC to execute specific commands by writing to the command register.
What state is given as the address of the next instruction?
Answer: The program counter is a pointer to the address of the next instruction to be executed for this process. Miscellaneous CPU registers where processes need to be stored to run for operational state.
Which day born baby is lucky?When is an instruction executed?
The program to be executed is a set of instructions stored in memory. The central processing unit (CPU) executes the program’s instructions to complete a task. The main responsibility for instruction execution lies with the CPU. Instruction execution takes place in the CPU registers.
Why does RISC have more registers compared to CISC?
These “reduced RISC instructions” require fewer transistors of hardware space than the complex instructions and leave more space for general purpose registers. Because all instructions execute in a consistent amount of time (i.e., one cycle), pipelining is possible.
Which register contains the top address?
The stack register contains the address of the top of the stack in x86. In x86, the main stack register is called the stack pointer or SP. The stack register is typically used to store information about the block of main memory used during the execution of the program.
Which tennis player has the most expensive watch?What is an effective debit address?
Load Effective Address calculates its src operand in the same way as the mov instruction, but instead of loading the contents of that address into the dest operand, it loads the address itself.
What is the contact of the stack pointer?
A stack pointer is a small register that stores the address of the last program request on a stack. A stack is a specialized buffer that stores data from top to bottom. As new requests come in, they “push down” the older ones.
How do I run regsvr32?

What specifies the address of the next instruction?
The register that stores the address of the next instruction is called the program counter. Normally, after each instruction is executed, the program counter is incremented by one (hence the use of the word counter), so that it contains the address of the next instruction.
What can be stored in a register?
Registers (processor registers, CPU registers)
A processor (CPU) register is one of a small group of data storage locations that is part of the computer processor. A register can contain an instruction, a memory address, or any type of data (such as a string of bits or individual characters).
Where is the fetched statement stored?
The instruction fetched is stored in the instruction register in the CPU and the program counter is incremented to point to the next instruction in memory.
What are the three basic steps in the command execution cycle?
It consists of three main stages: the fetch stage, the decode stage, and the execute stage.
Is ROM a memory?
RAM, which stands for Random Access Memory, and ROM, which stands for Read-Only Memory, are both present in your computer. RAM is volatile memory that temporarily stores the files you are working on. ROM is non-volatile memory that permanently stores instructions for your computer.
Which register contains a copy of the executed command?
In computing, the instruction register (IR) or current instruction register (CIR) is the part of a CPU’s control unit that contains the instruction that is being executed or decoded.
What are the two main phases of command execution?
Retrieve command from memory. Decode the statement. Read the effective address from memory. Execute the statement.
What is the most basic type of machine instruction?
The most basic type of machine instruction is the data transfer instruction. The data transfer directive needs to specify several things. First, the position of the source and destination operands must be specified. Each memory location could be a memory, a register, or the top of the stack.
Is the ARM processor RISC or CISC?
An ARM processor belongs to a family of CPUs based on the Reduced Instruction Set Computer (RISC) architecture developed by Advanced RISC Machines (ARM). ARM makes 32-bit and 64-bit RISC multi-core processors.
Which contains the address of the information?
In a computer, the memory address register (MAR) is the CPU register that stores either the memory address from which data is fetched to the CPU or the address to which data is sent and stored.
Which register is used as the stack pointer?
Stack registers in x86
In 8086, the main stack register is called Stack Pointer – SP. The stack segment register (SS) is typically used to store information about the memory segment that stores the call stack of the currently executing program.
