One form of this construct exhibits optimal performance with the impossible-to-implement Bélády’s algorithm. The valgrind utility is used to debug errors with this construct. Insufficient (10[1])locality of this construct leads to thrashing, which involves pages of it constantly swapping. Calling “free” twice can lead to an incorrect access of this construct (10[1])called a segfault. Pointers are so named (10[1])for “pointing” (10[1])to this construct. A form of this construct known as a cache can be used to reduce the number (10[1])of reads (10[1])and writes to this construct’s “random-access” form. (10[1]-5[1])For 10 points, name this construct whose size is measured in gigabytes. (10[1])■END■
