All configuration data about the computer including information about device drivers and devices used at startup is contained in the registry. Errors in the registry are often the cause of degraded computer performance.
it is used to contain the dynamic settings for any plug and play devices in your computer
The Registry is a database that stores your computer hardware,software,security,user settings or profiles,and property settings for folders and programs. When you perform a normal full boot of your computer,Windows process the information in the Registry to properly configure your computer. For example,the Registry contains information on hardware devices and resources (such as IRQs,I/O addresses, and DMA channels)assigned to both Plug and Play and legacy devices. During booting Windows uses this information to identify and configure hardware devices,reconfigure hardware devices (if necessary), and update the Registry. Microsoft recommends that you use tools, such as Device Manager, the Control Panel, and property sheets, to make configuration changes, rather than opening and editing the Registry. If you open the Registry and make a mistake while you are changing a configuration setting, you might not even be able to use your computer, or you might introduce errors in its hardware and software configuration so that it does not function properly. It's also important to note that if you open and make a change to the Registry, Windows does not warn you if the change you made in incorrect.
The registry key that contains Plug and Play information about the hardware configuration used by the computer at startup is located at HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum. This key stores details about all detected hardware devices, including their configuration and status. It is essential for the operating system to manage hardware resources effectively during the boot process.
Actually, when we do a lot of work in our computer like installation/uninstallation of program & devices, surfing and download something from web, all this create a registry entry in the windows registry. These sluggish entries in windows registry make windows speed slower or sometimes stop doing work. Registry cleaner is the right solution to clean these unwanted registry entries.
It is neither. In addition to input devices and output devices, there are devices called storage devices. The hard drive of a computer is a storage device: it contains the operating system and any data or program files used by the computer.
The "tower" part of a computer contains most of the computer. It is the cabinet that contains input and output devices, as well as storage devices. However, collectively speaking, the label of "processing device" would be more accurate. Or you can say it is an I/O and processing device with storage.
used to store much of the information and settings for software programs, hardware devices, user preferences, operating system configurations, and much more.
That would be the BIOS chip it finds all of your hardware.
To manage simple devices (system BIOS)To start the computer (startup BIOS)To change settings on the motherboard (CMOS setup).
Neither. A computer contains both input and output devices. Many modern input and output devices contain embedded computers, that interface between the main computer and the actual input or output hardware of the device.
You simply change the settings of your iPod to "Manual". iPod default settings are set to "Sync", which causes music to be deleted automatically from your iPod when connected to a different computer. Plug your iPod into a computer. Under the "Devices" section, you will see the settings of your iPod. Click on "Music" and change the setting to Manual.
