In Linux, there are many compression commands. Using these compression commands, you can easily download large files from the network. At the same time, we know that the Linux File Extension has no special significance. However, because there are

In general C Programming, bit operations are not frequently used, so they are often forgotten. the day before yesterday, I did a Data Structure assignment in the school. I had to ask for the power of 2 n. I just moved it to the left and right for

Several RAID Modes 1. RAID0 That is, Data Stripping Data sharding technology. RAID 0 can connect multiple hard disks into a larger hard disk group to improve disk performance and throughput. RAID 0 has no redundancy or error repair capability. It is

If you want to buy a car and your primary goal is performance or, more specifically, primitive power, then the answer is clear if you choose between a 4-cylinder engine and an 8-cylinder engine, because the larger the value, the better. Generally,

I was reading an interview question last night and found that some people were not particularly clear about the priority of CSS styles. In addition, I have been summing up this knowledge point, today, I will take some time to write down what I know

When I was in a company, it looked very bad, that is, the state of an object is represented by Int. Personal perception mainly has the following shortcomings. Advantages of enumeration: 1. Although int is a strong type in C #, Int Is not a strong

I found a lot of good information when studying the stm32 serial port to receive sending interruptions, and now the backup is here. For your reference and convenience. TC === txe By the way, I will write a post about serial port data processing

Usage and technology of compressed files Using Compression Technology for Large files can reduce the size of large files. Some compression programs can also split large files into several small files! Currently, the computer systems we use are

The encryption is too complex.AlgorithmImplementation is very difficult, so in the past, many applicationsProgramOnly simple encryption technologies can be used. The result is that the encrypted data is easily decrypted. However, you can use the

Serial Port is short for serial port, also known as serial communication interface or COM interface. Serial communication refers to the communication mode that uses the serial communication protocol (Serial Communication) to transmit data from one
