Computer expert, please come in and help me explain N nouns

1. I will take a look at it all in combination with the second floor.

Turn off the power: It is to disconnect the power supply in a certain way. The way you do this may be by manually pressing the power switch, or you can turn off the power through the system power. It's what we usually call a soft shutdown!

Shut down the system: In fact, the system here can be a system of multiple applications with different attributes on a single computer. Because there is a lot of application software, and most of these systems may have power controls.

If you're talking about Windows, and if you have both W7 and XP on your computer. In fact, there are two meanings of shutting down the system, one is to change the system, Biqiang changes from W7 to XP, but it must be achieved by restarting. The other is shutting down, which is to turn off the system power to achieve the purpose of shutting down the computer.

In fact, the meaning of the two depends on what you think! Usually no one tries to separate them so clearly. Because there is no special meaning!

Module, is a memory module, refers to the memory module, that is, DDR or DDR2SATA, serial bus hard disk protocol, a little faster than PATA hard disk, support hot-swappable IDE, PATA hard disk, optical drive interface form.

Jumper is the switch to select different functions.

RAID, which is composed of whole columns of disks.

Dual-machine hot standby, two machines are turned on at the same time, and one machine is a real-time backup of the other machine.

It is one of the windows directory""file, which is constantly expanding and shrinking automatically. Virtual memory is like the L1 and L2 cache of the CPU and the 512K-2M cache of the hard disk. If the computer only has 64M physical memory, when reading a 100M executable file, it is necessary to use a relatively large virtual memory, the file will be read by the memory first, and then stored in the virtual memory, and then the memory will store all the files in the virtual memory, and then the virtual internal storage and search files will be released to the original installation directory.

When the system starts, it must occupy some memory resources. Your computer is physically intrinsic to more than 79%, stating that there are still more than 79% physical intrinsic available. win/nt：

Because the lost files on the computer can be repaired with the original disk, the reinstallation can not have anything to do with the loss of the file on the computer. If you have some knowledge of ghost, you can use the ghost method to reinstall the system. As long as the disc is fine, the system can be reinstalled.

Of course, the CD-ROM drive should also have a good ability to read discs. I hope it inspires you. api ：

It's the Application Programming Interface. It is a set of functions that can be used to manipulate a component, application, or operating system. Typically, an API consists of one or more DLLs that provide some kind of special functionality.

A DLL is a file that contains functions that can be called by any application running under Microsoft 0 3 Windows 0 3. At runtime, a function in the DLL is dynamically linked to the application that calls it. No matter how many applications call a function in a DLL, only one file on disk contains the function, and the DLL is created only when it is called into memory.

Probably the API you'll hear the most about is the Windows API, which includes the various DLLs that make up the Windows operating system. Every Windows application interacts directly or indirectly with the Windows APIs. The Windows API guarantees that all applications running under Windows behave consistently.

That's all I know, and I hope it can help you!!

I only know a part of the explanation of the delay! Others need to come to the rest. Physical Memory:

It refers to the capacity of the memory module on the motherboard in the brain. I 0 port: refers to the input and output device interface (such as mouse, keyboard and other device interfaces) win32 platform:

Refers to your joke and clean up system processing techniques.

Electronic computer (electronic computer), commonly known as computer, is a modern electronic computer machine used for high-speed computing, which can carry out numerical calculations and logical calculations, have storage and memory functions, and can run according to the program, and automatically and high-speed processing of massive data.

It consists of a hard delivery system and a software system, and the computer without any software is called bare metal. Computers are used as control systems for a variety of industrial and consumer equipment, including simple purpose-built equipment, industrial equipment, and general-purpose equipment.
