In many cases, soft interrupts and "signals" are somewhat similar, while soft interrupts are also corresponding to hard interrupts, " har

The following is my personal learning Linux/unix environment programming summed up the difference between soft links and hard links, for reference only
Soft links can be cross file systems, hard links are not available.
Hard links and source files share an inode, which means that it is essentially the same file, and the soft links have their own inode with the
classes. Because garbage collection has a specific nature, the reference classes may not be as useful as you originally thought. However, they are useful for specific problems. Soft reference, weak reference, and phantom reference objects provide three different methods to reference heap objects without interfering with collection. Each referenced object has different behaviors, and their interaction with the garbage collector is also different. In a
A glimpse of Linux's distinction between hard connection and soft connection I. Two connection files in Linux and their creation methods. There are two connection files in Linux mdash; although both soft connection and hard connection are connected files, there is a big difference between the two.
