user state to the kernel state switching operation, the key steps involved are completely consistent, no difference, is equivalent to the execution of an interrupt response process, because the system call is actually finally the interrupt mechanism implementation, The exception and interrupt processing mechanisms are basically consistent, and the specific differences about them are not mentioned here. Details and steps about the interrupt handling m

Inter-process Communication-mmap#include The essence of mmap is to synchronize the memory with the files on the hard disk. The contents of a block of memory are synced to the hard disk file, which maps the files to memory. Therefore, the communication between processes is achieved through the reading and writing of the same file.Parameter explanation:Addr: Specifies where to map the block of memory. A null

generally 3, factory settings are as follows: Net.ipv4.tcp_tw_recycle = 1 Net.ipv4.tcp_tw_reuse = 1 Net.ipv4.tcp_fin_timeout = 30 Net.ipv4.tcp_fin_timeout, default 60s, reduces fin_timeout, reduces the number of time_wait connections. Net.ipv4.tcp_tw_reuse = 1 means to turn on reuse. Allows time-wait sockets to be re used for a new TCP connection, which defaults to 0, indicating shutdown; Net.ipv4.tcp_tw_recycle = 1 is a quick recycle of time-wait sockets on a TCP connection, and the default

The mechanism of inter-process communication-the semaphore. Note: Please do not confuse it with the previously mentioned signal, the signal and the semaphore are different two kinds of things. A lot of other things about the signal, to be able to read one of my articles:Linux interprocess communication-Uses signals . The following is an explanation of the signal volume. first, what is the signal volumeto pr

We have previously investigated and summarized the usage of the Unified Communication System. The investigation shows that enterprises do not fully understand the situation. Now, let's summarize the meaning of Unified Communication and the scope of service they focus on. Let's imagine that we can communicate with each other at any time, anywhere, or any device, i
