Today, I suddenly have an idea, why so long 5,000 years, mankind has not been defeated by various diseases, the previous years of SARS, now the pig flow. Because people are sick and someone cares, there is no sick person to help you to give the strongest counterattack, so we can ice, but has not fallen. These two days I am not comfortable, bao son to buy me the first day of the flu capsule exclamation, the next day to buy me a liquid cough medicine,

Specific to the optimization of the logical execution plan, users can choose the appropriate optimization rules according to their own situation (also can be understood as the optimization of this piece has great potential to dig).

Differences between registers and memory Both registers and memory can be used for reading and writing, but register operations have side effects) Reading a register may change the content in the register. For example, in some device interrupt status registers, the registers are autom

Introduction to an IO modelTo better understand the IO model, we need to review it in advance: synchronous, asynchronous, blocking, non-blockingWhat is the difference between synchronous (synchronous) IO and asynchronous (asynchronous) Io, what is blocking (blocking) IO and

I. I/O portA port is the address of a register in an interface circuit that can be accessed directly by the CPU. Almost every peripheral is made from a register on a read-write device. The CPU sends commands to the registers in the interface circuit through these addresses, namely ports, to read the status and transmit the data. Peripheral registers, also known as "I/O ports", typically include: control registers, status registers, and data registers, and the registers of a peripheral are usuall

What is the difference between synchronous IO and asynchronous Io, what is blocking IO and non-blocking IO respectively? The answers given by different people in different contexts are different. So first limit the context of this article.本文讨论的背景是Linux环境下的network IO。A concep

Question: I am studying windows SDK programming recently. I plan to share my learning summary and experiences with you, for more information, see Asynchronous Io is an essential feature of modern operating systems. It makes valuable CPU computing resources not wasted waiting for slow Io. Its behavior is intuitive. after sending an IO request, the user thread do

each block device or partition of a block device has its own request queue (request_queue), and each request queue can select an I/O Scheduler to coordinate the request submitted . The basic purpose of the I/O Scheduler is to arrange requests according to the sector code they correspond to on the block device to reduce the movement of the heads and improve efficiency. Requests in the request queue for each device are responded to in order. In fact, in addition to this queue, each scheduler itse

A. Almost every peripheral is done by reading and writing registers on the device. Peripheral registers are also known as "I/O ports, usually includes: control registers, State registers and data registers three categories, and a peripheral register is usually continuously address. There are two ways for the CPU to address the physical addresses of peripheral IO ports: One is I/O mapping (i/o-mapped) and the other is the memory-mapped method (memory-m

Java (java io-File class), io-1. In the entire io package, the only class that indicates the File itself is the File class. You can use the File class to create or delete files. To use the File class, first observe the construction method of the File class. The common construction methods of this class are as follows: public File (String pathname)-> when instanti

Management of I/O Ports and I/O memory in Linux Port is the address of the register that can be directly accessed by the CPU in the interface circuit. Almost every type of peripherals is performed by reading and writing registers on the device. The CPU sends commands to registers in the interface circuit through these addresses to read the status and transmit data. A peripheral register, also known as an "I/O port", usually includes three categories: control registers, status registers, and data
