the program counter, also known as the instruction pointer or simply pc, is a fundamental component of a computer's central processing unit (cpu). it is a special register that keeps track of the memory address of the next instruction to be executed in a program. why is the program ...
A program counter is a register in the CPU (Central Processing Unit) containing the address of the next instruction to be executed from memory. For example, when your computer is turned on, a signal places the decimal number F000 into the CPU. This action tells the computer to look at ...
The Central Processing Unit (CPU) is the main component in a computing device responsible for executing instructions and performing calculations. Often described as the "brain" of the computer, the CPU handles several critical tasks:Instruction Execution: The CPU processes instructions from software ...
A program counter is a specialregisterin a computerprocessorthat contains the memory address (location) of the next program instruction to be executed. Before the CPU fetches an instruction frommemory, it references the program counter for the correct memory address. After the CPU fetches the instr...

1 Post Your Answer Jul, 200615 Program counter holds the address of either the first byte of the next instruction to be fetched for execution or the address of the next byte of a multi byte instruction, which has not been completely fetched. In both the cases it gets incremented automaticall...
People frequently describe a computer's CPU in terms of the human brain. This is an apt analogy since the CPU (central processing unit) controls computer operation. It does this by executing instructions provided by computer programs on data that come fr
Running the input through the PLC’s program logic will result in output values that it can pass to other devices. Output signals transfer through the I/O terminal to external devices such as conveyors, valves or actuators. Once the output stage is complete, the PLC will repeat the entire ...
A CPU bottleneck occurs when the CPU is the limiting component within a computer system limiting its overall performance.
