Restarting a computer also is called rebooting, which can be "hard", e.g. after electrical power to the CPU is switched from off to on, or "soft", where the power is not cut. On some systems, a soft boot may optionally clear RAM to zero. Both hard and soft booting can be initiated by hardware such as a button press or by a software command.
On reboot, everything in tmpfs will be lost. The memory used by tmpfs grows and shrinks to accommodate the files it contains. Many Unix distributions enable and use tmpfs by default for the /tmp branch of the file system or for shared memory. This can be observed with df as in this example:
At the end of the hardware initialization, the boot ROM will try to load a bootloader from external peripheral(s) (such as a hard disk drive or solid-state drive, an eMMC or eUFS card, a microSD card, an external EEPROM, and so on) or through specific protocol(s) on a communications port (such as a serial port or Ethernet, etc.).
AccessData's FTK Imager 2.5.3.14 was validated by the National Institute of Justice (NIJ) in June 2008. Their findings indicated that "If a physical acquisition is made of a drive with hidden sectors in either a Host Protected Area or a Device Configuration Overlay, the tool does not remove either an HPA or a DCO.
This makes it impossible to restart parts of the program without having to reload it all. However, if a program ends with the system call INT 27h or INT 21h/31h, the operating system does not reuse a certain specified part of its memory. The original call, INT 27h, is called "terminate but stay resident", hence the name "TSR". Using this call ...
Microsoft provides a tool called the "SDI File Manager" (sdimgr.exe) which can be used for the purpose of manipulating SDI files. Some of the tasks which this tool facilitates are: The creation of an SDI image file. The creation of an SDI image file from an existing hard disk partition. The verification of an existing SDI image.
Many memory-capable digital circuits (flip-flops, registers, counters and so on) accept the reset signal that sets them to the pre-determined state. This signal is often applied after powering on but may also be applied under other circumstances. After a hard reset, the register states of many hardware have been cleared.
Windows 2000 is a major release of the Windows NT operating system developed by Microsoft and oriented towards businesses. It is the direct successor to Windows NT 4.0, and was released to manufacturing on December 15, 1999, [2] officially released to retail on February 17, 2000 for all versions, and on September 26, 2000 for Windows 2000 Datacenter Server.
