In software systems, because IO is slower than memory, I/O reading and writing can become a bottleneck in many situations. Increasing the I/O speed has great benefits for improving the overall performance of the system.In Java's standard I/O, stream-based I/O implementations, InputStream and OutputStream, are provided. This stream-based implementation processes data in bytes and makes it very easy to set up various filters.NIO is the abbreviation for

The most common problems in front-end interviews are page optimization and caching (which seems to be page optimization too). After being asked several times, you may not be able to use it, however, it is difficult to tell me what I know. Page optimization is obviously not a sentence or two. In the past two days, I have summarized CSS-related optimization knowledge, written a blog, and hope you can give me more advice. CSS optimization mainly starts from two aspects. Network
