Question 1 of 16
All Questions (16)
A) A physical artifact that can run a program.
B) A group of interconnected computing devices capable of sending or receiving data.
C) A system of linked pages, programs, and files.
D) The maximum amount of data that can be sent in a fixed amount of time.
Correct Answer: B
Content point 7 explicitly states, 'A computer network is a group of interconnected computing devices capable of sending or receiving data.' Option A defines a computing device, C defines the World Wide Web, and D defines bandwidth.
A) The Internet is a system of linked pages, while the World Wide Web is a network of interconnected networks.
B) The Internet uses proprietary protocols, whereas the World Wide Web uses open protocols like HTTP.
C) The Internet is a global network of networks, while the World Wide Web is a system of information (like pages and files) that uses the Internet.
D) The Internet and the World Wide Web are two terms for the same system.
Correct Answer: C
Content point 13 defines the Internet as a 'computer network consisting of interconnected networks.' Points 24 and 26 describe the World Wide Web as a 'system of linked pages, programs, and files' that 'uses the Internet.' This shows the Web is a system that runs on top of the Internet.
A) The packets will always arrive in the correct sequence.
B) The packets are guaranteed to arrive, but may be out of order.
C) The packets may arrive out of order, or some may not arrive at all.
D) The packets are reassembled into the correct order during routing and before they reach the destination.
Correct Answer: C
Content point 22 states, 'Packets may arrive at the destination in order, out of order, or not at all.' This directly supports option C and refutes the guarantees suggested in options A and B.
A) It is the primary chunk of data being sent, such as part of an image or text.
B) It increases the bandwidth of the network for faster transmission.
C) It contains information for routing the packet and for data reassembly.
D) It is an agreed-upon set of rules that specifies the behavior of the system.
Correct Answer: C
Content point 21 specifies that packets contain 'a chunk of data and metadata used for routing the packet, as well as for data reassembly.'
A) Proprietary
B) Dynamic
C) A data stream
D) Scalable
Correct Answer: D
Content points 18 and 19 define scalability as 'the capacity for the system to change in size and scale to meet new demands' and state that 'The Internet was designed to be scalable.' This directly addresses the scenario of handling growth.
A) A sequence of directly connected computing devices.
B) A physical artifact, such as a router or server.
C) An agreed-upon set of rules that specifies the behavior of a system.
D) A group of computing devices and programs working together.
Correct Answer: C
Content point 15 provides a direct definition: 'A protocol is an agreed-upon set of rules that specify the behavior of a system.'
A) Encapsulation
B) Routing
C) Scaling
D) Bandwidthing
Correct Answer: B
Content point 10 defines routing as 'the process of finding a path from sender to receiver.' This matches the scenario described.
A) Number of computing devices on a network.
B) Physical distance between a sender and a receiver.
C) Maximum amount of data that can be sent in a fixed amount of time.
D) Total number of packets that arrive out of order.
Correct Answer: C
Content point 11 states, 'The bandwidth of a computer network is the maximum amount of data that can be sent in a fixed amount of time.'
A) All computing systems are computer networks.
B) A computer network is a specific type of computing system.
C) Computing systems and computer networks are entirely separate concepts.
D) A computer network connects devices, while a computing system is just a single device.
Correct Answer: B
Content point 6 defines a computing system as 'a group of computing devices and programs working together.' Point 7 defines a computer network as 'a group of interconnected computing devices.' Critically, point 8 clarifies the relationship: 'A computer network is a type of computing system.' This makes B the most accurate choice.
A) It guarantees that all data packets arrive in the correct order.
B) It allows users to easily connect additional computing devices to the Internet.
C) It ensures that routing paths are specified in advance for maximum efficiency.
D) It increases the bandwidth of all network connections.
Correct Answer: B
Content point 16 directly links open protocols to a specific benefit: 'The protocols used in the Internet are open, which allows users to easily connect additional computing devices to the Internet.'
A) It involves finding a path from a sender to a receiver.
B) It is usually dynamic.
C) It is typically specified in advance.
D) It determines a sequence of directly connected computing devices for data to follow.
Correct Answer: C
Content point 17 explicitly states, 'Routing on the Internet is usually dynamic; it is not specified in advance.' Therefore, being specified in advance is NOT a characteristic.
A) IP, TCP, and UDP
B) Packets, data streams, and metadata
C) Computers, tablets, and routers
D) The Internet, the World Wide Web, and HTTP
Correct Answer: C
Content point 5 defines a computing device and provides a list of examples: 'Examples include computers, tablets, servers, routers, and smart sensors.' Option C is a subset of this list.
A) The user is using the Internet, which is a system of linked pages that relies on the HTTP protocol.
B) The user is using the World Wide Web, which is a network of networks that uses protocols like TCP and IP.
C) The user is using the HTTP protocol, which is another name for the Internet's packet-switching system.
D) The user is using the World Wide Web, which uses the HTTP protocol and relies on the Internet for transmission.
Correct Answer: D
This question requires synthesizing multiple points. Point 24 defines the World Wide Web as a system of pages. Point 25 states HTTP is a protocol used by the Web. Point 26 states the Web uses the Internet. Option D correctly combines these facts.
A) As a single, unbroken electrical signal from sender to receiver.
B) As a data stream containing chunks of data encapsulated in packets.
C) As a system of linked pages and files sent all at once.
D) As a predefined path of routers that never changes.
Correct Answer: B
Content point 20 directly answers this: 'Information is passed through the Internet as a data stream. Data streams contain chunks of data, which are encapsulated in packets.'
A) Internet, World Wide Web, Router
B) Packet, Data Stream, Path
C) IP, TCP, UDP, HTTP
D) Scalability, Bandwidth, Routing
Correct Answer: C
The question asks for a list of protocols. Content point 23 lists 'IP, TCP, and UDP are common protocols used on the Internet.' Content point 25 adds another: 'HTTP is a protocol used by the World Wide Web.' Option C correctly lists these.
A) The maximum amount of data that can be sent between them.
B) A group of programs working together for a common purpose.
C) A sequence of directly connected computing devices.
D) An agreed-upon set of rules for their communication.
Correct Answer: C
Content point 9 provides the definition: 'A path between two computing devices on a computer network is a sequence of directly connected computing devices.'
