First, Operating System HistoryWikipedia search operating systemOperating System(English:Operating System,Abbreviations:OS) is the managementComputerHardwarewith theSoftwareof ResourcesComputer Programs, but also the core and cornerstone of computer systems.

The resource management functions of the operating system include: Processor management, storage management, input/output management and file system four functions.1. Processor ManagementThe most important resource in a computer system is a central processor, and any computation must be run on the CPU. The most importa

the lowest performance state when the processor is idle, it is recommended to turn off (enabled by default)C States (c State), allows you to enable or disable the processor to operate in all available power states, recommended off (enabled by default) CPU priority selection of high frequency (computing power), followed by the choice of more than the number of cores (can be multi-threaded concurrent processing, using multi-instance).Note: since MySQL is a single process, multi-threaded working m

PXE (Pre-Boot execution Environment) is an Intel-designed protocol that enables a computer to boot over a network rather than from a local hard disk, optical drive, and so on.Modern NICs, typically embedded with PXE-enabled ROM chips. When the computer boots, the BIOS puts the PXE client into memory execution and displays the Command menu,After the user chooses, the PXE client will be placed on the remote operating

R (n (1-r) 2) 2Analysis: First you can see that this system is composed of two parallel subsystems and a subsystem to form a series system:First parallel subsystem: N (1-r) (1-r) = N (1-r)2Second subsystem: RThird Parallel subsystem: N (1-r) (1-r) = N (1-r)2The three are concatenated together to get the result: R (1-R) 2) 2Four, die redundancy systemM-mode redundancy

Distributed System The fundamental starting point and purpose of the distributed system: the pursuit of multi-level cooperation and strong. Compared with computer networks, distributed systems: 1. multi-machine cooperation: Automatic task allocation and coordination; 2. Strong: when one or more computers or networks in the system fail, the rest of the
