In the computer system, please explain what an interruption is, and please draw an interruption processing process with a flowchart...

Interruption also refers to a single-chip microcomputer interrupt system, including interrupt devices and interrupt processors.

Analysis and exclusion: check whether the computer system is working normally; check the network configuration of this computer; check whether the network card of this computer is working normally; check whether the network card settings on this computer conflict with other resources; check whether the network cable is disconnected; check the contact of the network cable connector Whether it is normal or not.

The interrupt priority only stipulates the response of the interrupt device.The order of interruptions that occur at the same time. When the interrupt device responds to a post-interrupt interrupt handler, the interrupt device may also respond to another interrupt event.

Program direct control method: that is, the user process directly controls the information transmission between memory or CPU and peripherals. In this way, the controllers are all user processes. ( 2) Interrupt control method: It is used to control the data transmission between peripherals and memory and CPU.

Generally, the number of svchost.exe processes in Windows 2000 is 2, while the number of svchost.exe processes in Windows XP has increased to 4 and more than 4. Check the network connection. It is mainly the network card.

The input device is a device that transmits information to the computer from the outside world.In computer systems, the most commonly used input devices are keyboards and mice, as well as light pens, digitizers, digital cameras, image scanners, etc. The function of the output device is to transmit the data in the computer to an external medium and convert it into a form recognized by people.

How to install 32-bit software on a 64-bit system

1, double-click acad.msi or setup.exe to install normally. When choosing the installation location, it is best in Pro Under the folder of gram Files (x86), others can be installed in the same way as under a 32-bit system.

2. You can try to run them in compatibility mode. In WiIn the ndows operating system, you can right-click on the executable file of the software or driver, select "Properties", and then select the appropriate compatibility mode in the "Compatibility" tab.

3. The popular Android system on mobile phones is generally 64-bit systems that can be backward compatible with running 32-bit programs. In the commonly used windows operating system, if the program prompts an abnormality when running, right-click the program executable file and select the [Compatibility] tab: select "Run this program in compatibility mode".

4. In the pop-up menu, click [Properties] below the interface. Continue to click [Compatibility] above the interface. The software cannot be installed on the 64-bit operating system. Memory usage of 32-bit system: The 32-bit version of the standard version supports 93GBRAM, and the 64-bit version can support up to 32GBRAM.

What are the common file types in the Windows system?

File types are mainly divided into three categories according to content: video, audio and software. File format (or file type) refers to the special encoding method of information used by computers to store information, which is used to identify internally stored data.For example, some store pictures, some store programs, and some store text information.

Text file type: including ASCII, MIME, .txt and other formats. ( 1) The ASCII standard allows text files containing only ASCII characters to interact freely between Unix, Macintosh, Microsoft Windows, DOS and other operating systems.

Executable file: refers to a file that can be run by itself, also known as an executable program, and its extensions are mainly. EXE,. COM and so on. Double-click the executable file with the mouse, and it will run by itself. For example, double-click the mspaint.exe file in the C: WINDOWSSystem32 folder to start the "drawing" program in the Windows system.

In the windows system, the attributes of the file include

In Windows, the attributes of a file include read-only, hidden, system, archive. Archive attribute (archive) refers to an attribute that can be used to mark in the attributes of a file or folder (hereinafter referred to as the file). Common file attributes include system attributes, hidden attributes, read-only attributes and archive attributes.

In Windows, the attributes of a file include read-only, hidden, system and archive. Readonly, also known as readonly, means that documents or attributes can only be read, cannot be modified or stored.
