Polling in the context of the 8085 microprocessor refers to the method of checking the status of an external device or peripheral by the CPU at regular intervals. Instead of waiting for an interrupt signal from the device, the CPU actively queries the device to determine if it requires attention or has data to send. This method can lead to inefficient CPU usage, as it consumes processor cycles while checking devices that may not need servicing. Polling is often contrasted with interrupt-driven I/O, where the device signals the CPU when it needs to communicate.

What is mean by polling delay?
That is the day you vote.
What does polling mean in email?
"Polling" is simply the gathering of information from the public by means of randomly questioning a sample of people.
What is the instruction for exit in 8085 microprocessors?
There is no exit instruction in the 8085. Do you mean return, as in from a function or interrupt? If so, the instruction is RET.
What is polling in microcontrollers?
mean that the processor of mcu will check spesfic registers in loop way while (1) { if (PINA = ... ) then >>>>> if(PINB = ... ) then >>>>>>>> if(PINC = .....) then >>>>>>>. } here the processor polling polling for this register
What does polling frequency mean?
Polling frequency refers to how often a system or device checks for new information or updates. A higher polling frequency means it checks more frequently, while a lower frequency means it checks less often. Adjusting the polling frequency can impact performance and efficiency of the system.
Why the name 8085 Why the name 8085 for microprocessor?
8085 is a microprocessor designed by Intel
Can 8085 CPU replace 8086 CPU?
No. The 8086 has instructions not present in the 8085. The 8086 was marketed as "source compatible" with the 8085, meaning that there was a translator program which could convert assembly language code for the 8085 into assembly language code for the 8086. However, this does not mean that the compiled 8086 assembly code would then run on an 8085; among other things, the 8086 was a true 16-bit processor, as opposed to the 8085 which was an 8-bit processor that supported a few 16-bit operations.
Why the 16 bit 8085 microprocessor is not possible?
The 8085 was replaced with the 8086/8088. As such, there is no 16 bit version of the 8085.
What does ppp mean on a caller ID on your phone?
When you get a call and you see PPP on the caller ID it means Public Policy Polling. The calls are coming from a polling company wanting you to complete a survey.
Difference between 8080 and 8085?
The 8085 has a single +5V power supplyThe 8085 has a multiplexed low order address busThe 8085 has extra single pin interrupts, TRAP, RST7.5, RST6.5, and RST5.5The 8085 has serial I/O pins SID and SODThe 8085 has maskable interrupts and the RIM/SIM instructionThe 8085 includes the functionality of the 8224 clock genereator and 8228 system controllerThe 8085 added several 16 bit operations
What is a sentence for polling booth?
The polling booth was hacked during the elections.We need to be at the polling both by midday.
When 8085 processor was invented?
The 8085 was introduced by Intel in 1977.
