What's the difference between restart and shutting down completely consequently rebooting?

When your computer is completely rotten, and you turn it on, it first goes through POST (Power On System Test) and loads information from the BIOS (Basic Input/Output System). This allows the computer to authorize the processor, memory, and any drives (hard drive, floppy, CD). It will then determine which drive have the information for booting your OS (operating system - usually Windows) and load it.



When you do a "restart" the computer does not repeat the POST and BIOS. It begins at the point where on earth it knows the location of the OS and reloads it.



Most of the time, a "restart" is adjectives that is necessitate to fix an issue with a PC or complete the installation of a unusual software, driver, etc. However, there are times when the computer wants to load the POST and BIOS (such as during the installation of a latest hardware device). If that is the covering, the instructions will clearly state to Shut Down and then repower the PC.
Technically nought.
Nothing. Rebooting is just a moment or two quicker, with smaller number physical interaction from the user.
They are physically different. Reboot takes one doings. The other takes two engagements. The result is the same.



Add: dewcoons is upright, but not completely correct. Maybe he talks nearly soft reboot (?). Each time my computer is rebooted it does the POST and bios and check everything (hardware). Opps, I am using Linux.
