Question 11

The Semantic Web project envisions words on Web pages being tagged with their meanings.

Accepted Answer

The Semantic Web project aims to add a layer of meaning to the content on the Web by tagging words with metadata to enable better search results and machine interpretation.

Question 12

The term "cascading" is used in cascading style sheets because designers can apply many style sheets to the same Web page, one on top of the other.

Accepted Answer

Cascading refers to the way styles are prioritized and applied in a specific order, with styles applied last taking precedence over earlier styles. This allows designers to layer different style sheets for different purposes, such as a general layout style sheet, a typography style sheet, and a layout adjustment style sheet.

Question 13

The higher the bandwidth, the faster the transmission of data through a communication medium.

Accepted Answer

A higher bandwidth allows for more data to be transmitted per unit of time, leading to faster data transmission through a communication medium.

Question 14

_____ creates a private passageway through the public Internet that provides secure transmission from one computer to another.
A) IP tunneling
B) Circuit switching
C) Encapsulation
D) Subnetting

Accepted Answer

IP tunneling creates a private passageway through the public Internet that provides secure transmission from one computer to another. It is achieved by encapsulating the original message and forwarding it through a series of routers using a pre-determined tunneling protocol. Circuit switching is a technique used by the telephone network to establish a dedicated communication path between two devices. Encapsulation is a technique used in IP tunneling to add an additional layer of headers to the original message in order to transmit it through a tunnel. Subnetting is a technique used in IP addressing to divide a network into smaller subnetworks.

Question 15

_____ determine how a sending device indicates that it has finished sending a message and how the receiving device indicates that it has received the message.
A) Routers
B) Semantics
C) Protocols
D) Switches

Accepted Answer

Protocols determine how communication devices indicate the start and end of a message transmission. They also determine how a receiving device acknowledges receipt of the message. Routers and switches are both networking devices, while semantics refer to the meaning of language and communication.
