A computing device is
a group of computers working together for a common purpose
a machine that can run a program
a sequence of direct connections
a bunch of hardware put together
a computing network is
a sequence of direct connections
a machine that can run a program
a group of connected computers that can send or receive data
a group of computers working together for a common purpose
Which of the following best describes the protocols used on the Internet?
The protocols of the Internet are designed by government agencies to ensure they remain free to use
The protocols of the Internet are secret to maintain the privacy and security of people using them
Each device connected to the Internet will use a protocol designed by the company that manufactured it
The protocols of the Internet are open and used by all devices connected to the network
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?
Both devices are using the same shared and open protocols
A single direct connection is established between any two devices connected to the Internet
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 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 were designed to scale as new devices are added
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 is true of how packets are sent through the Internet?
Packet metadata is only included on important packets to indicate they should get access to faster paths through the network
Packet metadata is used to route and reassemble information travelling through the Internet
Information sent through the internet is only encapsulated in packets if the message is too large to be sent as a datastream
Information sent through the internet is split into two packets, one which contains the message and another which contains the metadata
Answer
Two devices are connected to the Internet and communicating with one another. A squirrel chews through one of the wires in the network that is currently being used by the devices to communicate. The network immediately begins using a different path through the network and communication continues as normal.
This situation best exemplifies which principle?
fault-tolerance
scalability
protocol
pathing
An Internet Service Provider (ISP) is a company that builds the routers and wired connections that allow individuals to access the Internet.
An ISP is considering adding additional redundant connections to its network. Which of the following best describes why the company would choose to do so?
It costs less to design a network that is redundant
The protocols of the Internet only work on networks that are redundant
Redundant networks are more reliable
Adding additional connections reduces the fault-tolerance of the network

Which of the following best describes how computing devices represent information?
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 data as bits which is either a 0 or a 1
A computer represents information as bits which contain 8 bytes.
Convert the binary (base-2) number 1001 to decimal (base-10).

Which of the following is true of lossy and lossless compression algorithms?
Lossy compression algorithms are used when perfect reconstruction of the original data is important.
Lossy compression algorithms are typically better than lossless compression algorithms at reducing the number of bits needed to represent a piece of data.
Lossless compression algorithms are only used to compress text data.
Lossless compression algorithms only allow for an approximate reconstruction of the original data.
A school is developing a program to keep track of information about students and their class schedules. In which of the following instances would a data abstraction be most helpful?
The program includes individual variables to store the names of each student rather than a single list of students.
A program includes multiple comments that could be combined into a single comment
A program includes repeated programming statements that could be moved inside a loop
A program includes repeated code that could be moved inside a function.

All Hackers are bad
True
False
phishing is
A technique that attempts to trick a user into providing personal information. That personal information can then be used to access sensitive online resources, such as bank accounts and emails.
Information about an individual that identifies, links, relates, or describes them.
Software intended to damage a computing system or to take partial control over its operation.
The use of a program to record every keystroke made by a computer user in order to gain fraudulent access to passwords and other confidential information.
Malware is
The use of a program to record every keystroke made by a computer user in order to gain fraudulent access to passwords and other confidential information.
Software intended to damage a computing system or to take partial control over its operation.
a red flag
A technique that attempts to trick a user into providing personal information. That personal information can then be used to access sensitive online resources, such as bank accounts and emails.
public key encryption is
Pairs a public key for encryption and a private key for decryption. The sender does not need the receiver's private key to encrypt a message, but the receiver's private key is required to decrypt the message.
Involves one key for both encryption and decryption.
A process that reverses encryption, taking a secret message and reproducing the original plain text.
A process of encoding messages to keep them secret, so only "authorized" parties can read it.
