Hiding the complexity with something simpler

Making a photo smaller but more pixelated

When visiting a museum Sue takes a photo of a painting with a smartphone which stores the photo as an image file. Which of the following best describes the differences between the painting itself and the photo of the painting stored on the smartphone?

The photo is a digital representation of the analog painting

Both the painting and the photo are analog

Sampling can be used to determine whether the analog image is an accurate representation of the painting

The phone can represent the photo in either digital or analog formats depending on the sampling technique that is used

Lisa takes a picture with her smartphone which she subsequently posts online. Allen finds the picture online and posts a copy of it on his website with an attached Creative Commons license. Which of the following best describes who owns the photo?

Lisa owns the photo because she was the original creator and did not license the work.

Allen owns the photo because only holders of a Creative Commons license can own works online.

Lisa owns the photo because it was granted a Creative Commons license by another person online.

Both own the photo because creating a copy makes it her intellectual property.

Ryan is designing an app that needs to quickly send low quality photos between users. Most smartphones take much higher quality photos than Ryan needs for his app. Which answer best describes the type of compression Ryan should choose and why?

Lossy compression since it typically results in smaller data sizes.

Lossless compression since it ensures perfect reconstruction of the photo.

Lossy compression since it ensures perfect reconstruction of the photo.

Lossless compression since it typically results in smaller data sizes.

Which of the following is true of lossy and lossless compression algorithms?

Lossy compression algorithms are typically better than lossless compression algorithms at reducing the number of bits needed to represent a piece of data.

Lossy compression algorithms are used when perfect reconstruction of the original data is important.

Lossless compression algorithms are only used to compress text data.

Lossless compression algorithms only allow for an approximate reconstruction of the original data.

Which of the following is true of how computers represent numbers?

With a fixed number of bits some numbers are too large to represent in a computer which will lead to overflow errors.

Using a fixed but large number of bits can eliminate the possibility of round off error when representing numbers in binary

Using a fixed but large number of bits, for example 128, eliminates the possibility of overflow errors.

With a large but fixed number of bits it is possible to eliminate either round-off errors or overflow errors, but not both.

Which of the following best describes how computing devices represent information?

A computer represents data as bits which is either a 0 or a 1

A computer will either represent information as bits or bytes but not both

A computer represents data as a byte which is either a 0 or a 1

A computer represents information as bits which contain 8 bytes.

Pick the two statements that are true about the Internet Protocol (IP):

Each device or computer on the Internet is assigned a unique IP address.

IP is the shared way that all devices and computers label their messages with the sender and receiver's addresses.

Each network on the Internet uses its own protocol to address messages.

IP is a secret protocol shared between the sender and receiver.

In order to communicate two devices on the Internet must have the same IP address

Describe how the Internet Protocol (IP) allows devices to easily connect and communicate on the Internet.

IP addresses are like phone numbers that you use to connect to devices

IP addresses don't change so you can always communicate with a device

IP addresses are given out by DNS servers and can be used to connect to various devices

What are the benefits of building redundancy into a network? (Choose all that apply)

If one path fails, the message could still be delivered

If one device fails, the message could still be delivered

If a packet is dropped, it can be resent

If a packet is received out of order, it can be placed in correct order

Which of the following is true regarding the way information is transmitted on the Internet?

Information does not travel in one piece, but rather as a datastream of packets.

Information flows on a dedicated direct connection from the sender's device to the receiver's device using binary electrical signals.

If a single packet is dropped, the entire file must be resent.

Because of the reliability of the Internet, packets always arrive in the same order they were sent.

What is a good definition for "protocol"?

How a path is chosen for a packet

An ID number for a computing device

What is the main function of a router?

Forward data from one device to another

Provide error checking for data

Give each device a unique IP address

What would make a network Fault Tolerant?

Using multiple locations for your network

Which of these are true of IPv4?

Undecillions of possible addresses

Which of these are true of IPv6?

Undecillions of possible addresses

Jesse purchases a new smartphone and is immediately able to use it to send a photo over the Internet to a friend who lives in a different country. Which of the following is NOT necessary to make this possible?

A single direct connection is established between any two devices connected to the Internet

Both devices are using the same shared and open protocols

The data of the image is routed through a sequence of directly connected devices before arriving at its destination

Both devices are directly connected to at least one part of the Internet

Which of the following is true of how the Internet has responded to the increasing number of devices now using the network?

The protocols of the Internet were designed to scale as new devices are added

The Internet protocols are changed every year to adapt to the new devices that have been connected to the network

While the number of devices connected to the Internet has grown, the network itself has not grown

The protocols of the Internet are no longer necessary thanks to the large number of devices now connected to the network

Which of the following situations is most likely to cause issues arising from the digital divide?

A state makes voter registration forms available only by visiting a government website

Two internet-connected devices located in different countries and thousands of miles apart attempt to communicate with one another

Packets sent from one router to another begin arriving in a different order than they were sent

A smartphone attempts to communicate over the Internet with another type of device, like a tablet or laptop

Any programming language that lets users create programs by manipulating “blocks” or graphical programming elements, rather than writing code using text.

Block-based programming language

Statements that should only run upon a specific user action should be placed

within an onEvent programming statement

after the first programming statement
