Rendszerórák

Rendszerórák, a Hungarian term, translates to "system clocks" in English. This refers to the internal timekeeping mechanisms within electronic devices, particularly computers and embedded systems. These clocks are crucial for synchronizing operations, scheduling tasks, and providing accurate timestamps for events.

In a computer, the system clock is typically managed by a hardware component called a Real-Time Clock (RTC), often powered by a small battery to maintain time even when the main power is off. The operating system then interacts with the RTC to set and retrieve the current time. This time is used for a wide range of functions, from logging system events to managing file modification dates.

Beyond general-purpose computers, system clocks are fundamental in embedded systems, such as those found in microcontrollers. These clocks dictate the pace at which the microcontroller executes instructions and controls peripheral devices. The accuracy and stability of these clocks are paramount for the reliable operation of devices ranging from simple appliances to complex industrial control systems. Synchronization between multiple system clocks, often achieved through network protocols like Network Time Protocol (NTP), is also a common requirement in distributed systems to ensure consistent timekeeping across different devices.
