address to the physical address is done by the hardware Device (memory management Unit, MMU). Users generate only logical addresses that must be mapped to physical addresses before they are used. The user program never sees a real physical address. 2. Dynamic Loading and DLL If the entire program and data of a process must be in physical memory, the size of the process is limited by the size of the physical memory. You can use dynamic loading, and the subroutine is loaded only when it is calle

Although he was excited about the operating system, Mark Shuttleworth, the creator of Ubuntu Linux, said he knew there was still a lot of competition in the enterprise market. "We must maintain a modest attitude to the outside," Shuttleworth said. "We know that we are new members of this game and there is a long way to go ." Shuttleworth a

partition size and position are not fixed, but the partition size is allocated according to the master inventory required by the job. 1. Primary storage allocation and de-configuration (recovery) During system initialization, in addition to the portion occupied by the operating system, the entire user zone is a large idle zone, which can be allocated in sequ

This code is used to sort out the FIFO buffer from the 30-day self-made operating system p135. Well written, so record it (added a function named fifo8_free to query the remaining capacity, which is useful ). The author implements a char buffer, but can replace it with any struct you want to transmit ~~~ Fifo8.h /* Overflow flag: 0-normal, -1-overflow */# define flags_overrun 0x0001/* Buf-buffer address siz
