[Case] recruitment and testing problems the human resources department of a company wants to recruit several engineers in a certain professional field. There are 10 multiple-choice questions, and each question has four alternative answers. Only one of them is correct. Or, the correct ratio is only 0.25. How many correct answers should be given before admission can be considered? (1) If I have five questions, do I have to consider admission? (2) If I h

To say clear Systemd, you have to start with the Linux operating system started speaking. The startup of the Linux operating system starts with the BIOS, then the boot Loader loads into the kernel and initializes the kernel. The final step in kernel initialization is to start the init process. This process is the first process of the system, PID 1, also known as the super process, called the root process. It is responsible for generating all other use

of virtual machines"1 , can simulate the real operating system, do a variety of operating system experiments (such as: Build a domain server, build a Web server, build FTP server, build a DHCP server, build a DNS server, etc.);2 , the snapshot capabilities of virtual machines are comparable to the Ghost tool backup feature, and you can quickly create restore points or recover restore points quickly;3 , can bridge to the real computer on the Interne

variable. If core 1 has ownership, the cache subsystem will invalidate the corresponding cache row in Core 2. When Core 2 acquires ownership and performs the update operation, core 1 will invalidate its corresponding cache row. This will go back and forth through the L3 cache, greatly affecting the performance. If the competing core is located in different slots, an extra cross-slot connection is required,
