What does counter mean in computer terms?
A program counter is a register in a computer processor that contains the address (location) of the instruction being executed at the current time. Some engineers refer to a program counter as an instruction address register or an address pointer.
What is program counter used for?
PROGRAM COUNTER. The program counter, PC, is a special-purpose register that is used by the processor to hold the address of the next instruction to be executed.
What are counters in microprocessor?
The Program Counter (PC) is a register structure that contains the address pointer value of the current instruction. Each cycle, the value at the pointer is read into the instruction decoder and the program counter is updated to point to the next instruction.
What does program counter contain?
A program counter contains the memory location of the next instruction. We can view a program counter as a modern digital counter. It facilitates faster execution of the instructions. Furthermore, it provides tracking of the execution points while the CPU executes the instructions.
What is counter and types of counter?
A digital circuit which is used for a counting pulses is known counter. Counter is the widest application of flip-flops. It is a group of flip-flops with a clock signal applied. Counters are of two types. Asynchronous or ripple counters.
Where is program counter stored?
Program Counter is a register in the CPU hardware. Effectively it’s a digital counter so consists of binary latches where each latch represents a binary bit. Number of latches,ie the size of the PC depends on the processor architecture.
Why is program counter needed in CPU?
A program counter (PC) is a CPU register in the computer processor which has the address of the next instruction to be executed from memory. It is a digital counter needed for faster execution of tasks as well as for tracking the current execution point.
What is counter in electronic?
In digital logic and computing, a counter is a device which stores (and sometimes displays) the number of times a particular event or process has occurred, often in relationship to a clock. The most common type is a sequential digital logic circuit with an input line called the clock and multiple output lines.
What is counter and delay?
COUNTERS ARE USED TO KEEP TRACK OF EVENTS. TIME DELAYS ARE IMPORTANT IN SETTING UP REASONABLY ACCURATE TIMING BETWEEN TWO EVENTS. COUNTERS A Counter is designed simply by loading an appropriate number into one of the registers and using the INR (Increment by one) or the DCR (Decrement by one) instructions.
What is counter in Java?
A counter variable in Java is a special type of variable which is used in the loop to count the repetitions or to know about in which repetition we are in. In simple words, a counter variable is a variable that keeps track of the number of times a specific piece of code is executed.

What is the function of counter in digital electronics?
According to Wikipedia, in digital logic and computing, a Counter is a device which stores (and sometimes displays) the number of times a particular event or process has occurred, often in relationship to a clock signal. Counters are used in digital electronics for counting purpose, they can count specific event happening in the circuit.
