Cache memory levels are determined by ________.

the chip’s proximity to the CPU

Running the Disk Defragmenter utility will ________.

Make the hard drive work more efficiently

A ________ performs the same kind of computational work that a CPU performs but is specialized to handle 3-D graphics and image and video processing.


Cache memory is a form of ROM.


Notebook and desktop processors are basically the same and therefore interchangeable.


Notebooks are often equipped with a(n) ________ slot that allows you to read flash memory cards such as CompactFlash, Memory Sticks, and Secure Digital cards.


When referring to hard drives, access time is measured in ________.


3D sound is the same as surround sound.


A(n) ________ uses the same kind of memory that flash drives use and have no spinning platters or motors.


The amount of RAM recommended for most systems today is measured in ________.


Moore’s Law is a rule that predicts ________.

An expansion card that translates binary data into images is a(n) ________.

video card

External hard drives are an ideal solution when you need more storage than a flash drive can provide.


When referring to hard drives, seek time and latency are the two factors that make up ________.

Access time

Upgrading your CPU can increase how quickly data can move to or from the CPU.


The video subsystem is made up of the video card and speakers.


The number of bits the video card uses to represent each pixel on the monitor is called ________.

bit depth

The amount of memory your video card needs depends on what you want to display on your monitor.


RAM is your computer’s permanent storage space for data that is entered from the keyboard.


A computer’s memory subsystem is made up only of RAM.


Which of the following activities is carried out by the ALU?

completion of all arithmetic calculations
