How to quickly obtain computer hardware information

Computer hardware information can be quickly obtained through Windows Built-in Device Manager or other hardware information detection tools.

Device Manager: Right-click the My Computer icon on the desktop, select Device Manager (or Manage, and select Device Manager on the left side of the Computer Management window).

Master Lu: <>

Other software, such as Driver Wizard and Driver Life, can also quickly and correctly obtain the hardware information in the machine.

LAN information collection software can collect information about monitors, motherboards, CPUs, memory, graphics cards, hard disks, MAC addresses, IP addresses, computer names, and operating systems.

The information is more comprehensive and can identify the details of multiple memory, graphics card, hard disk.

The new version adds software list reading and asset counting, asset filtering functions!

There are four main types: round-robin test IO mode (polling mode), interrupt handling mode, direct memory access (DMA) mode, and channel mode.

Round-robin test IO (polling method).

Take advantage of the Io test instructions to test the idle of the equipment. If the device is not busy, the input or output command is executed; If the device is busy, the test command continuously tests the device until the device is idle. This way makes the CPU spend a lot of time in the loop test of whether the IO is completed or not, which is a huge waste!

How the outage is handled.

When an interrupt is introduced, the CPU is notified with an interrupt request whenever the device completes an IO operation, and then it is processed accordingly. However, since the CPU directly controls the input and output operations, an interrupt occurs every time a unit of information is communicated, so it still consumes a lot of CPU time.

Direct memory access (DMA) mode.

DMA (Direct Memory Access) is used to transfer batch data between high-speed external devices and memory. It uses a special DMA control device, using the method of stealing control of the total thread, and the DMA controller sends the memory address and sends the control signal of memory read, device write, or device read and memory write to complete the direct data transmission between the memory and the device, without CPU intervention. When all the data transmitted by DMA is completed, an interrupt is generated, and the CPU is requested to end the processing.

Channel mode. Channel Kaizhi is a hardware mechanism used to control the operation of external devices, which is equivalent to a simple processing machine. The channel is a processor independent of the CPU, which is responsible for the input and output transmission of data, which manages the external devices in a unified manner, and controls the IO operation instead of the CPU, so that the IO operation can work in parallel with the CPU. Channels are the basis for realizing the parallelism of computers and transmissions to improve the efficiency of the whole system.

Do you know how to query the hardware information of the computer, the following is the content I brought to the computer hardware information query method, welcome to read!

Computer hardware information query method:

Open the desktop My Computer - right-click - Properties - General, here we can see the following information:

Operating system name, version number, patch number, registration information, CPU information, memory size;

Here are the basic computer configurations;

If you want to know the detailed information.

In"Hardware"Choose below"Device Manager", you can open all the physical hardware system information of the computer, as shown in the figure; Of course, it is usually very important for people who are new to computers to understand basic system information, so that at least others can't coax you to pull;

How do I configure my computer?

Configuring a PC is a DIY process; Let's first understand the hardware part of the computer;

Power supply, chassis, motherboard, CPU, memory, hard disk, optical drive, monitor, keyboard, mouse, and graphics card (some are integrated into the motherboard);

This is the basic building block of the computer, and of course you have to buy it from these parts to configure the computer;

DIY a computer, I give a picture of Bi Huang liquid show:

This is a DIY computer configuration, not very simple, not very difficult, the key is to take into account the compatibility of the parts and **;

If you want to know the hardware configuration of your computer system, there are two ways to do it:

1. Understand through the system's built-in program: The operating system itself provides a lot of applications to detect the configuration of computer hardware and software, and the commonly used ones can be operated by running the cmd window command.

1. SystemInfo: Click the desktop to start - run, enter "cmd", enter the cmd window, and then enter "systeminfo" and press enter, you can detect and display the computer software and hardware configuration information.

2. DXDIAG: Click the desktop to start-run, enter "DXDIAG" and press enter, then the computer software and hardware configuration information can be detected and displayed.

3. Device Manager): Click the desktop to start - run, enter "and press enter", you can detect and display the computer software and hardware configuration information.

How do I check the hardware information and system information of my computer? How many ways do you do without the help of third-party software?

To view the hardware information of a computer, there are many commonly used tools.

General information, you can use tools such as Master J, Elf, etc., which is completely sufficient for ordinary users.

Professional users, if you need detailed hardware information, you can use AIDA64, which is very old and professional, and can view extremely detailed hardware information.

LAN information collection software can collect information about monitors, motherboards, CPUs, memory, graphics cards, hard disks, buried bridge MAC addresses, IP addresses, computer names, and operating systems.

The letter is more comprehensive and can identify the details of multiple memory, graphics card, and hard disk. Curl sharply.
