The Select () system call can enable the process to dete

transmit data (for block migration), but also needs to modify the pointer values in all occupied blocks. Therefore, storage compression is also a system operation and is not required. 3. Coverage and Exchange Technology3.1 coverage technology Introduce Overwrite(Overlay)The goal of the technology is to run a large program in a small available memory. This technology is commonly used in multi-channel program systems and used in conjunction with parti

In network programs, it is common for a process to process multiple file descriptors at the same time. The Select () system call can enable the process to detect multiple I/O devices waiting for at the same time. When no device is ready, select () is blocked. When any device is ready, select (). Select () is called in the form: # Include # Include

When we need to call system commands, we should first consider the OS module. Use OS. System () and OS. popen () for operations. However, these two commands are too simple to complete complex operations, such as providing input or reading command output for running commands to determine the running status of the commands, manages parallel execution of multiple co

Zookeeper 1. The operating system assigns a virtual address ranging from 0 to 4G to each process. 2. Relationship between virtual memory and physical memory Summary: The minimum unit for memory management in program a is page (4096 bytes). If the required memory is less than 4096 bytes, it is actually 4096 bytes. B. Each program corresponds to an independent virtual memory. When calling this functi
