While we can simply watch the amount of memory used by a script by turning the system monitor on, it will not tell us anything more useful than the status of the entire system memory.
虽然我们可以通过启用系统监视器来简单观察内存的使用量,但是它不会告诉我们比整个系统内存状态更有用的任何内容。
System check shows current memory, required memory, space requirements, and whether operating system is at supported level.
系统检查显示当前内存、需要内存、空间需求以及操作系统是否支持。
If you set the buffer pool size too high, then system memory usage will exceed the available physical memory, causing the operating system to spend more time paging the memory.
如果缓冲池大小过大,那么内存使用会超过可用的物理内存,从而导致操作花费更多时间对内存进行分页。
I can certainly try to write the number 13 there, but bam, my program very likely will crash if this chunk of memory was not given to me previously by the operating system and maybe it is owned by the operating system.
我当然可以在那里写下数字13,但是“嘣“,如果这块内存不是系统预先给我的,我的程序很可能会崩溃,可能这块内存,是系统本身使用的。
Only the operating system has controlling of byte zero NULL in the computer's RAM and so if a function ever returns null, aka zero, well, something must have gone wrong because that can't possibly belong to me that memory because by human convention zero is owned by the operating system; not by a program I wrote.
只用操作系统在内存中能够控制,字节0,并且如果一个函数返回,或者说0,好的,可能出错了,因为那可能是不属于我的内存,因为惯例上,0是由操作系统拥有的,而不是由我的程序拥有的。
So, these memory cells are a way that your immune system keeps track of antigens that it's been exposed to for even if maybe the plasma cells that were producing antibody in response to the initial exposure have died and disappeared.
所以,这些记忆细胞,是人体免疫系统记忆抗原的一种方法,即使由浆细胞产生的抗体,在初次免疫应答中全部被消灭,记忆细胞仍然能迅速分化为抗体分泌细胞
