Which of the following statements is true about the relationship between hardware and software?
Application software runs independently of any hardware.
Hardware will not function without software, and software will
not run without the appropriate hardware.
Computer hardware drives computer software by providing
the instructions that tell the software what to do.
All software runs independently of any hardware.
RATIONALE
Hardware and software cannot function without each other. Without software to provide instructions that tell the
hardware what to do, computer hardware is useless. Conversely, computer software cannot be run without the
supporting hardware.

This process describes the interaction between the and .
touchpad, hard drive
mouse, flash drive
mouse, ethernet card
touchpad, visual card
RATIONALE

Logan has limited storage space remaining on her flash drive, so she only wants to transfer the smallest file
she has from her computer to her flash drive. She has four files to choose from, each with varying sizes.
Select the file with the SMALLEST size for Logan to transfer to her flash drive. Consider rewriting
each value using the same units.
6,000 GB
3 TB
90,000 KB
2 MB
RATIONALE
If we consider the units only, the order (smallest to largest) is KB, MB, GB, and TB. However, we must also
consider the number of units. We can rewrite each example in the same unit and order, as follows:
2 MB = 0.002 GB
90,000 KB = 0.09 GB
3 TB = 3,000 GB
6,000 GB = 6,000 GB
The smallest file size is 2 MB, so Logan should transfer this file to her flash drive.

Jake has a collection of 40 movies on Blu-ray discs.
How much space will he need to store them on a hard disk?
40 gigabytes
10 gigabytes
1 terabyte
100 kilobytes
RATIONALE
Jake would need at least 1 terabyte (TB) to store 40 movies on a hard disk. Remember that the space needed to
store video content depends on the specifications of the video format you are using.

Meredith just installed a new smart security system in her home, which allows her to turn offher alarm system
from her smartphone as she’s on her way home from work.
Meredith’s home security system is an example of .
a microprocessor
an SSD
an operating system
an integrated computer system
RATIONALE
Meredith's home security system would be an example of "smart house" technology, which integrates computers
into everyday products like our homes, and connects them to other devices such as phones or tablets.
Operating systems, microprocessors, and SSDs are all examples of individual computer technology elements
rather than integrated systems.

in short periods of time.
Select the best computer for Mel.
A handheld tablet computer
A desktop computer with two screens
A desktop computer with a fast processor
A portable laptop computer
RATIONALE
Because Mel analyzes and processes large amounts of data, he needs a computer with a fast processor.

Suzi is a writer who is using her keyboard to type a story. When she saves her work, her computer
issues a command and returns the results, which she checks to ensure that her work has been saved
properly.
The in Suzi's computer is responsible for executing the operation sent to it by the software.
ROM
CPU
keyboard
RAM
RATIONALE
When Suzi clicks to save her work, this command is sent to the computer's central processing unit (CPU). The CPU
carries out the operations or instructions it receives from software programs. Random-access memory (RAM) and
read- only memory (ROM) indicate the locations where the data is stored in the computer, but do not manage
instructions sent to them by software.

Select the true statement about the CPU.
It executes commands sent by program software.
It provides a central connection for computer components.
It permits the exchange of electrical signals between
computer components.
It transfers data from the hard disk for processing.
RATIONALE
The central processing unit (CPU) is considered to be the brain of the computer. The CPU carries out the
instructions of a computer program by performing the arithmetic, logical, control, and input/output (I/O)
operations specified by the instructions, and returning the results.

RATIONALE
Sydney's keyboard and mouse are both examples of input devices as they allow Sydney to send data into the
computer.
Output devices typically send data out from the computer to the user or to another device. Data storage and
data processing devices would likely be used by the computer after Sydney provides input from her keyboard and
mouse, but the keyboard and mouse themselves are not considered data storage or processing components.
