What was the channel factor that Nisbett described that increased the percentage of students who got a shot from 3 to 29%?

【判断题】把程序按段分对程序员是友好的,但是如果物理存储也按段存,则会导致大块的内存碎片,例如现在需要分个10M的段但是连续的存储空间只有8M/9M/5M三个。解决办法: (将段打散不存到页中)不要对内存进行连续的分配,将内存划分成1页1页,按页分配,1页4kb大小,最多浪费的也就4KB。这样不会有内存碎片,也不会出现没有符合要求大小的内存可以申请的情况,因为可以打散了分散到一页一页中。
