When two numbers a and b are XOR, the result is a number with all bits set to 1 wherever a and b’s bits vary. Example: In binary, 4 is denoted by 100 and 5, by 101. 5 and 4 can be XORed to produce 001, or 1. DecimalBinary Number 5 101 Number 4 100 Bitwise XOR 1 001...

Linux中的swap(交换空间)是一种内存管理技术,它允许操作系统将部分内存中的数据暂时移动到硬盘上的一个特定区域,以释放物理内存供其他进程使用。当系统内存不足时,swap空间可以作为额外的内存资源。 基础概念 Swap空间:通常位于硬盘上,用于模拟额外的内存。
