#TIME CLOCK SYSTEMS HARDWARE WINDOWS#

To check the system clock cycle in windows computer opens system properties or system information. In modern computers, the cycles are in billion cycles per second (GHz). In a computer, single or multiple instructions can be executed within a single cycle depending on how the CPU is designed. The clock cycle measures the number of cycles that a processor executes per second. When improving your system performance by overclocking the CPU this is the clock speed that is changed. Clock help to synchronize between fast and slow components so that they can operate in harmony. The kernel itself can set that bit if it determines that time isn’t synchronised, but it never clears it on its own.

Control the speed of BUSes and all other input-output components: different computer peripherals operate at different speeds depending on how and the type of data they consume. On Linux, the kernel expects time synchonisation services to report whether time is synchronised that is done by clearing or setting the STAUNSYNC status bit using the adjtimex system call.

It also can be used on the system log to identify who logged into the system and at what time. Without a synchronized clock this is not possible.

It gives the timestamps of activities done on the computer: when a user creates a document or a task it is given the time that it was created.

The scheduled activities include tasks like scanning for viruses, doing system backup, and system alarm among other tasks.

Handling the scheduled activities: user can schedule activities that will be triggered when a specific time is reached.

The activities can include the execution of processes or waiting for events to occur.

It is used to account for the CPU time: the clock enables the CPU to account for its time caring out respective activities.

For the time-sharing system, it ensures that each user uses the quantum of time allocated to them and no more. Clock ensures that each process doesn’t exceed the allocated time.

Preventing processes from running longer than they are allowed to: when processes are being executed in the CPU they are timed.

It is also used to operate the stopwatch if the computer supports that. It is given in hours minutes and seconds.

Maintaining the time of the day: the clock is used to give the date and time of the day.

Functions of the system clock in computers

#TIME CLOCK SYSTEMS HARDWARE SOFTWARE#

It synchronizes both the software and hardware components of the computer. It is used to synchronize all other operations within the computer system. This system clock is located on the computer motherboard. It is a hardware component within the computer. On computers, it is powered using a CMOS battery that also powers system BIOS that ensures it is powered even when the computer is turned OFF or it is on low power mode. It is powered by a different power source from the main system power. The real-time clock (RTC) is the main clock that is used to give the time of the day for the system. What is epoch time?
