Problem: Given the question: Question: "What do superscalar computers contain?"  Context: "Superscalar computers may contain multiple ALUs, allowing them to process several instructions simultaneously. Graphics processors and computers with SIMD and MIMD features often contain ALUs that can perform arithmetic on vectors and matrices."  Answer:
++++++++++++++++++++++++++++++++
The answer is:
processors


Problem: Given the question: Question: "Which of the following is not an alternative to rotary stepper motors: linear stepper motors, servomotors, or optical scanners?"  Context: "Stepper motors were and still are often used in computer printers, optical scanners, and digital photocopiers to move the optical scanning element, the print head carriage (of dot matrix and inkjet printers), and the platen or feed rollers. Likewise, many computer plotters (which since the early 1990s have been replaced with large-format inkjet and laser printers) used rotary stepper motors for pen and platen movement; the typical alternatives here were either linear stepper motors or servomotors with closed-loop analog control systems."  Answer:
++++++++++++++++++++++++++++++++
The answer is:
optical scanners


Problem: Given the question: Question: "what is the memory viewing a bunch of at the end?"  Context: "A computer's memory can be viewed as a list of cells into which numbers can be placed or read. Each cell has a numbered "address" and can store a single number. The computer can be instructed to "put the number 123 into the cell numbered 1357" or to "add the number that is in cell 1357 to the number that is in cell 2468 and put the answer into cell 1595." The information stored in memory may represent practically anything. Letters, numbers, even computer instructions can be placed into memory with equal ease. Since the CPU does not differentiate between different types of information, it is the software's responsibility to give significance to what the memory sees as nothing but a series of numbers."  Answer:
++++++++++++++++++++++++++++++++
The answer is:

numbers
