memory
Most ____ bottlenecks occur when the applications you are running require more memory than is physically available in the computer.
processor
A ____ bottleneck occurs when there is too much work for a processor to do.
Disk

COMPUTER SCIENCE
A two-dimensional finite automaton (2DIM-DFA) is defined as follows. The input is an $m \times n$ rectangle, for any m, $n \geq 2$. The squares along the boundary of the rectangle contain the symbol # and the internal squares contain symbols over the input alphabet $\sum$. The transition function $\delta: Q \times(\Sigma \cup\{\#\}) \longrightarrow Q \times\{\mathrm{L}, \mathrm{R}, \mathrm{U}, \mathrm{D}\}$ indicates the next state and the new head position (Left, Right, Up, Down). The machine accepts when it enters one of the designated accept states. It rejects if it tries to move off the input rectangle or if it never halts. Two such machines are equivalent if they accept the same rectangles. Consider the problem of determining whether two of these machines are equivalent. Formulate this problem as a language and show that it is undecidable.
