Problems with the operating system win7 understand people to come

BootMGR is the system bootloader, which is the same as the NTLDR of XP (that is, it is related to the selection screen at boot).

The files that are used to save memory (the same size as your physical memory) when the system is in hibernation will be automatically deleted by the system when hibernation is turned off.

It is virtual memory (simply put, a part of the space on the hard disk is used as memory).If you think you have enough memory, you can set the virtual memory to 0 or set it to the D drive.

The reason why these three files can't be deleted is because they are all system files and there are processes that are using them.

After Windows 7 is installed by default, it will be available under the system disk.

These are a few hidden files, and they are all empty files, so if the landlord doesn't install other software, the files you delete have no effect on the system.

bootmgr.For the maintenance of the system at startup, the system hibernation is a file that disappears when the hibernation function is turned off.

Virtual memory. If you have enough space on the C disk, don't worry about the system files, don't delete the things of the landlord's C disk at will, there are restore points, just restore, but it's also useful to create before you delete it. I'm also using win7 for a long boot time.,It's not normal.。

You use Win7 Rubik's Cube. Inside there are Boot Optimization, System Security, Repair. If it doesn't work, you can reinstall the system with whatever you install in the system

Don't delete, this is a necessary system file for booting,,, and then delete you will have to reinstall the system. Ay.

The operating system can use virtual technology for file management.

Virtualization technology refers to the fact that the operating system emulates hardware resources through software, so that users can not feel the boundaries between software and hardware. The operating system uses virtualization technology to achieve file management in the following ways:

Virtual file system: The operating system can use a virtual file system for file management. A virtual file system can treat different storage devices (such as hard disks, flash drives, optical disks, etc.) as a whole, allowing users to manage files in these storage devices in a unified way.

Virtual memory: The operating system can use virtual memory for file management. Virtual memory can combine memory and hard disk, allowing users to automatically transfer a portion of memory content to the hard disk when memory is low, thus saving memory space.

Virtual machines: The operating system can use virtual machines for file management. Virtual machines can run multiple operating systems simultaneously on a single physical computer, allowing users to store files separately in different virtual machines for easy management.

Virtualization technology can abstract a computer's hardware resources, such as memory, disk, CPU, etc., into a set of virtual devices for use by the operating system. These virtual devices can be used to store files, and the operating system can use the file system to manage those files.

For example, in the Windows operating system, each disk has a corresponding virtual device, and the operating system uses the NTFS file system to manage the files on those disks. Users can use the file manager to browse, search, delete, or copy files.

In addition, the operating system can also use virtualization technology to implement virtual disks. A virtual disk is a piece of software that creates a virtual disk partition in the computer's memory where the user can store files. The advantage of virtual disks is that users can test new software or recover files without affecting the real disk.

The file is missing, you can reinstall it.

Hello, Windows 7 comes with the driver is basically OK, it is recommended to upgrade the graphics driver.

You can restore to Vista then you must have a Vista system disk quality that is not reliable, just not fully functional.

Also, install it, hurry up and patch it, update your graphics card driver, update your directx, and make up for it anyway.

There is also the compatibility of Rescue Win7.

(1) Because the main memory capacity is 1m, because 2 20 = 1m, (2 10 = 1024 = 1k,), the main memory address needs to be represented by 20 bits.

2) There are 256 blocks in total, and the block size is the same as the page size. So there are 256 pages, so the size of each page is 1m 256 = (2 20) (2 8) = 2 12, so the length of each page is 12 bits.

Main storage address = page block number * block size + page address.

So the answer to the original question: (0 pages are assigned to 2 pages, that is, the page block number is 2, and the page block number of pages 1, 2, and 3 is 3, 1, 5).

Page No. Start Address.

0 2 * (2 12) + 0 = 8192 (this number is decimal).

4) Same as the third question.

Original question: Memory address.
