1
Select the true statement about the motherboard.
It acts as a storage point for read-only memory (ROM).
It executes the commands sent to it by the application software.
It provides much of the electrical connection between dif
ferent computer parts.
It acts as the working memory of the computer by transferring data from the hard disk for processing.
RATIONALE
A motherboard is a printed circuit board that contains the principal components of a computer or other device. It includes connectors into which other circuit boards can be slotted. A motherboard provides much of the bus of the computer, and is the main circuit board where the memory, storage, and CPU connect.
CONCEPT
Which of the following statements about the relationship between hardware and software is FALSE?
Application software, which does something useful, is a main category of software.
Application software runs independently of any hardware.
Computer software drives computer hardware by providing the instructions that tell the hardware what to do.
Hardware will not function without software, and software will not run without the appropriate hardware.
RATIONALE
It is not true that application software runs independently from hardware. Hardware and software cannot function without each other. Without software, computer hardware is useless. Conversely, computer software cannot be used without supporting hardware.
CONCEPT
The Relationship Between Hardware and Software 3
Which external hardware component is shown in the given image?
Mouse
Keyboard
Touchpad
CD/DVD drive
RATIONALE
The image depicts a keyboard from a laptop computer. Keyboards are peripheral devices that enable users to input text and numbers to a computer system.
CONCEPT
Which of the following is an example of computer software?
A memory storage device
A smartphone
An antivirus program
An audio/sound card
RATIONALE
Computer software is intangible. Unlike computer hardware, It cannot be touched.
An antivirus program is an example of computer software because it is a set of written instructions for computer hardware. Memory storage devices, sound cards, and smartphones are not examples of software. They are examples of tangible computer hardware.
CONCEPT
5

operating system
utility software
application software
productivity software
RATIONALE
When she downloads new software, Talia must ensure that it is compatible with her smartphone’s operating system.
CONCEPT

Jessica is a freelance writer who only uses a computer when she works in her home office. She typically writes for four to six hours a day.
Select the best computer for Jessica.
A laptop computer with multimedia content
A desktop computer with a large screen
A laptop computer that connects to āthe cloudā
A portable tablet computer
RATIONALE
Jessica can use a desktop computer because she does not need mobility. She also needs a large screen because she works for long periods of time.
CONCEPT
7
James is a college student who is writing a research paper. Because he clicked the command to save his work, he knows that after he turns his computer off, his work will be there for when he turns it on again.
James saves his work in a type of computer storage known as the ______.
microchip
CPU
RAM
hard drive
RATIONALE
James saves his work in a type of computer storage known as a hard drive. Hard drives are data storage devices that store and retrieve digital information (data). They are made up of one or more rigid, rapidly-rotating disks that are coated with magnetic material.
CONCEPT
The Primary Functions of a Computer 8
Select the true statement about a printer.
It is an input device that captures an image and converts it into digital information.
It is an output device that generates a hard copy of work created on a computer.
It is an input device that moves a pointer on screen and provides buttons for users to click.
It is an output device that displays video, images, or text on a screen.
RATIONALE
All of the answer choices describe peripheral devices, which can be categorized as output, input, or storage. A printer is an output device that generates a hard copy (e.g., printed paper) of work that has been created on a computer.
CONCEPT
All of the following are examples of integrated computer systems, EXCEPT:
Taking a self-driving car to work
Re-setting a home security system using a tablet computer
Storing a group project on “the cloud”
Using a watch to get directions during a morning run
RATIONALE
Smart homes, self-driving cars, and smart watches are all examples of the integration of computer technology into everyday products.
Storing a project on “the cloud” is an example of the growing prevalence of “cloud computing”ā the storage and transfer of data via the World Wide Web.
CONCEPT
Select the image of the CPU.
1
2
3
4
RATIONALE
A CPU is usually located on one silicon chip, and can perform a variety of functions. It carries out the instructions of a computer program by performing the arithmetic, logical, control and input/output (I/O) operations specified by the instructions.
CONCEPT
Kate saves her work on a secondary storage device that is fairly new, and uses flash technology instead of disks.
Kate is using a(n) ______ drive.
CD/DVD-ROM
optical disk
hard disk
SSD
RATIONALE
Kate is using a solid-state drive (SSD). An SSD is a storage device that uses integrated circuit assemblies as memory to store data persistently.
CONCEPT
Computer Components and Roles 12
Select the file size that is the SMALLEST.
3 TB
6 ,000 GB
2 MB
,000 KB
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:
- MB = 0.002 GB
90,000 KB = 0.09 GB
- TB = 3,000 GB
6 ,000 GB = 6,000 GB
The smallest file size is 2 MB.
CONCEPT
Approximately how much storage is needed to save a single digital picture in a 4-megapixel resolution?
1 gigabyte
1 byte
1 megabyte
1 kilobyte
RATIONALE
The amount of storage space needed to save a single digital picture in a 4-megapixel resolution is 1 megabyte.
CONCEPT
Data Storage 14
Which of the following components is used for data processing?
Scanner
USB flash drive
Solid-state drive (SSD)
Network interface card (NIC)
RATIONALE
A network interface card (NIC) is used for data processing because it enables computers to connect to a network.
Flash drives and solid-state drives are used for data storage. A scanner is a peripheral input device.
CONCEPT
Computer Components and Roles 15
Select the statement that best describes the a mainframe computer.
It could run programs and store data on a single silicon chip, which increased computing speeds and efficiency.
It enabled corporations and universities to store enormous amounts of data, sometimes on devices which occupied an entire room.
It enabled users to organize information through word processing and database programs from their desktop.
It enabled people to connect to a central server and share data with friends, business partners, and collaborators.
RATIONALE
Mainframe computers enabled organizations to store large amounts of data, and their microprocessors enabled rapid computation speed. Personal computers (PCs), including the Apple II, were much smaller than mainframe computers.
During the 1980s, a number of companies sold PCs that fit on a desk and enabled users to manage information themselves with a variety of programs. During the 1990s, personal computers in a workplace were connected to a central computer, known as a server. Together, these connected computers formed local area networks (LANs).
CONCEPT
Using his smartphone, Jeremy taps his finger to select a song to listen to on his headphones.
