Many programs use wait functions to run, whether they check something every second or store the duration of an action. Other functions may need to run a pin high for a certain length of time. All of these require an accurate and consistent time keeping mechanism to run off of.
Remember, the microcontroller will not be connected to a computer while it is running, so it will not be able to access the computer's clock. It needs its own.

What is the relationship between clock rate and clock cycle time in a computer system?
The clock rate and clock cycle time in a computer system are inversely related. A higher clock rate means a shorter clock cycle time, allowing the system to process instructions faster. Conversely, a lower clock rate results in a longer clock cycle time, slowing down the processing speed of the system.
What and how a quartz clock mechanism works?
A quartz clock is a clock that uses an electronic oscillator that is regulated by a quartz crystal to keep time. This crystal oscillator creates a signal with very precise frequency, so that quartz clocks are at least an order of magnitude more accurate than good mechanical clocks. Generally, some form of digital logiccounts the cycles of this signal and provides anumeric time display, usually in units of hours,minutes, and seconds. Since the 1970s, they have become the most widely used timekeeping technology.
What is the pace of the system clock called?
The pace of the system clock, called the clock speed, is measured by the number of ticks per second. The faster the clock speed, the more instruction the processor can execute per second.
What is the relationship between clock cycle time and clock rate in a computer system?
The clock cycle time and clock rate in a computer system are inversely related. A shorter clock cycle time allows for a higher clock rate, which means the computer can process instructions faster. Conversely, a longer clock cycle time limits the maximum clock rate that can be achieved.
What is the clock cycle time for the processor in this system?
The clock cycle time for the processor in this system is the duration it takes for one complete cycle of the clock signal, determining the speed at which the processor can execute instructions.
Why crystal oscillator used for microcontrollers?
Oscillators are connected externally with the microcontroller to provide high frequency signal to the oscillator circuit in the microcontroller. The oscillator circuit provides the clock signal to the micro controller. Usually "PIEZO CRYSTAL OSCILLATORS" are used in micro controllers.
What is the purpose of an oscillator crystal?
"A circuit within a computer that creates a series of pulses that pace the computer's electronic system. The oscillator clock synchronizes, paces and coordinates the operations of the computer's circuit." -- webopedia
Oscillator on the board usually measured in MHz is the?
Oscillator on the board typically measured in MHz is the clock oscillator, which generates clock signals for synchronizing the operations of various components on the board. This frequency determines the operating speed of the system and is crucial for maintaining proper timing and synchronization within the circuit.
What is a pulse rate of a clock measured in?
frequency of an oscillator crystal
What is the Maximum clock frequency of 8086 microprocessor?
that depends on the microcontroller. check the datasheet.
What is a purpose of time card clock?
The purpose of a time card clock is to accurately know hourly employee's time in the office. This system is being replaced by employees clocking in on the computer.
Do 8086 have in built clock?
The 8086/8088 has a clock oscillator circuit. You provide a crystal, and it will generate a clock signal that controls the speed of the processor. In that respect, it has a clock.The 8086/8088, however, does not have a time of day or date clock. You can build a software entity that keeps day/date time using interrupts from a divider off of the clock oscillator but, that is not the same thing as a non-volatile clock chip such as provided in the PC, but which is not part of the 8086/8088.
What is pipelining in pic microcontroller?
In PIC Microcontroller , During the Fatching of instruction no. 1it needs of one clock cycle, then after for the exicution of instruction no. 1 it reqires one extra clock cycle , but at the same time it fatches inst. no. 2 . Similarly, during the execution time of inst. no. 2 , it fatches inst. no. 3 and so on.In other words we can say that, PIC Microcontroller requires 2 clock cycle at starting the after it requires only one clock pulse. In this way we can say that instruction pipelining is done in PIC microcontroller.
What regulates the cpu machine cycle?
the clock oscillator and machine cycle state machine, it may take multiple clock cycles per machine cycle.
What reason an oscillator may be used to keep time is the?
If you divide the number of oscillations since you synchronized your clock (with an external source) by the frequency of the oscillator, you will get the number of seconds that have passed since you performed the synchronization...
What is avr microcontroller?
it is a programmable logic device which has a inbuilt memory, clock etc and is required to perform a specific task.
How do you connet clock signal?
To connect a clock signal, first identify the clock output pin on the source device (like a microcontroller or oscillator) and the corresponding clock input pin on the target device (like a digital circuit or FPGA). Use a suitable wire to make the connection, ensuring it is as short as possible to minimize signal degradation. Additionally, if necessary, include pull-up or pull-down resistors to stabilize the signal and prevent floating states. Finally, ensure that both devices share a common ground to avoid issues with signal integrity.
