What is Reboot?

What is Reboot

The term "reboot" refers to the process of restarting a working computer with hardware (such as a power button) rather than software. The most typical causes for rebooting include installing a software package, re-initializing drivers or hardware devices, or because apps are not functioning for some reason. Also, this process helps to resolve a variety of computer issues, including slow processing and freezing.

On most Windows systems, you may restart by going to the start menu and selecting "turn off computer," and then clicking "restart" in the pop-up box. Another option (and one that sometimes works when the previous one fails) is to use the Ctrl-Alt-Delete keystroke combination, which may be used to reboot a computer speedily and easily but is unlikely to be used by accident.

Rebooting a computer by hitting the computer's power button or using the keystroke combination is referred to as a warm boot, maybe because it is milder as compared to the alternative cold boot (turning the computer off and then back on by pressing the power button twice). It takes less time to restart a system from a running state than it does to restart it from a shutdown or closed state.

How to do a hard reboot

To perform a hard or cold reboot, press and hold the power button on the computer. The PC should turn off after 5-10 seconds. Wait a few seconds after turning off the computer before turning it back on.

What should happen when I reboot?

All open programs should shut when a computer is rebooted. The computer should then turn off for a few seconds before turning back on.

Why should I reboot?

A variety of computer issues, including software issues, Internet connectivity issues, slow processing, and freezing, can be resolved by rebooting a computer. In essence, it "restarts over" any code that isn't operating properly.

Reboot vs. restart

Is there a difference between restarting and rebooting? What about a computer, router, phone, or other electronic equipment that needs to be reset? It may seem silly to discriminate from each other, but they actually have completely different meanings.

The distinction between restart and reset is significant because, while sounding similar, they perform two completely different functions. One is far more destructive and long-lasting than the other, and there are numerous circumstances in which you must decide which action to take in order to finish a task.

All of this may seem confusing and difficult, especially when phrases like soft reset and hard reset are used, but keep reading to find out what these terms mean and what you should do if one of these terms comes in a troubleshooting guide or if Tech Support tells you to perform one or the other.

Restart means to Turn Something Off

The terms soft reset, power cycle, restart and reboot are all interchangeable. If you are advised to soft reset your laptop, power cycle your router, reboot your computer or restart your phone, you should turn it off, unplug it from the wall or battery, and then turn it back on.

Rebooting a device is a typical activity that you can perform on a variety of devices if they are not performing as expected. It is possible to restart a desktop computer, phone, tablet, smart device, modem, laptop, and other devices.

To put it another way, rebooting or restarting anything involves cycling the power status. The device does not receive electricity when you switch it off. It is getting power when it is turned back on. A restart or reboot is a single action that entails turning something off and then on again.

When the majority of devices (such as PCs) are switched off, all software programmes are also shut off. This includes any movies you're watching, websites you're surfing, documents you're editing, and so on. After the device is turned back on, the programmes and files must be reopened.

Despite the fact that both the operating software and the electricity are turned off, neither the software nor the open programmes are erased. When the power goes out, the applications are simply turned off. You can then open the same software programmes, games, files, and so on once the power is restored.

Note: A regular shutdown differs from putting a computer into hibernation mode and then completely shutting it down. This is because the contents of the RAM are written to the hard drive and then restored when the computer is restarted, rather than flushed away.

You can restart a gadget by yanking the power line from the wall, disconnecting the battery, or using software buttons, but these aren't always the best options.

Reset means to Erase and Restore

Because phrases like soft reset, restart, reboot are occasionally used interchangeably despite having two completely distinct meanings, understanding what "reset" implies can be perplexing.

The most straightforward explanation is that resetting is the same as erasing. A restoration, often known as a factory reset, is the process of restoring a device to its original condition (also a hard reset). Because the only way to do a real reset is to uninstall all of the current software, it's effectively a wipe-and-reinstall of a machine.

Consider the case when you have forgotten your router's password. You will be in the same scenario if you merely reboot the router: you don't know the password and have no way of signing in.

However, the original software that came with the router will replace the software that was operating on it before the reset if you reset the router. Any changes you made after purchasing the program, such as generating a new password (which you forgot) or setting up a Wi-Fi network, will be wiped when the new/original software takes over.

Note: Remember that the words "reset," "hard reset," "factory reset," and "restore" all refer to the same thing: erasing software.

Here's why it's important to know the difference

We discussed this earlier, but it's crucial to grasp the repercussions of mixing up these two terms:

For instance, if you are advised to "reset the computer after you install the application, you're being forced to remove all of the software on the computer just to install a new program. This is certainly an error, and rebooting the computer after the installation would have been preferable.

Same as merely restarting your smartphone before selling, it is probably not the greatest option. Instead of resetting or reinstalling the OS, which would destroy all of your customized apps and any remaining personal information, rebooting the device will just turn it off and on.

If you are still facing a problem remembering the differences, consider the following: The terms restart and reset refer to redoing a startup and setting up a new system, respectively.

Simulated reboot

Software running on any operating system can simulate a reboot. The Sysinternals BlueScreen program, for example, may be used for pranking, and the BSOD XScreenSaver "hack" can be used for fun in certain modes. Malware has the ability to replicate a reboot in order to deceive a computer user for malicious purposes.

In order to create a virtualized software bundle for clients, the Microsoft App-V sequencing tool records all of an installer's file system operations. When an installer detects that a reboot is required as part of the installation process, it will stop the advised reboot and instead simulate it by restarting services and loading/unloading libraries.


Operating systems now have more control over hardware power management features thanks to advanced power management. Because newer operating systems can handle varied power levels, you can use Advanced Configuration and Power Interface to sleep and/or hibernate. Hibernation is similar to rebooting in that it includes turning a system off and then on again. However, the operating system does not restart from the beginning.
