Accepted Answer

The most important parts of a Web page are the content, layout, and functionality. While graphics, photographs, and small programs can enhance the user experience, they are not the most important elements.

Question 3

_____ 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 by encapsulating the data packets and sending them through a virtual private network (VPN) tunnel. Circuit switching is a type of communication in which a dedicated physical path is established for the duration of the transmission. Encapsulation is the process of adding a header and trailer to the data packets to provide information about the source, destination, and type of data. Subnetting is the division of a single network into multiple smaller networks to improve network performance and efficiency.

Question 4

Files and e-mail messages sent over the Internet are broken down into small pieces called _____.
A) messages
B) switches
C) circuits
D) packets

Accepted Answer

Files and e-mail messages are broken down into packets so that they can be transmitted efficiently over the Internet. Each packet is sent individually and can take different paths to reach its final destination, where it is reassembled into the original message or file.

Question 5

IPv6 uses a _____ number for addresses.
A) 32-bit
B) 56-bit
C) 128-bit
D) 48-bit

Accepted Answer

Question 6

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

Accepted Answer

This is because higher bandwidth allows for more data to be transmitted at once, resulting in faster speeds.

Question 7

The combination of telephone lines and the closed switches that connect them to each other is called a _____.
A) LAN
B) WAN
C) circuit
D) pathway

Accepted Answer

The term "circuit" refers to a complete path that allows for the flow of electricity or, in this case, communication signals. Therefore, the combination of telephone lines and the closed switches that connect them to each other is called a circuit. Choices A and B are not applicable as they refer to different types of networks, and choice D is too general and does not specifically relate to the telephone lines and switches.

Question 8

_____ specifies the format of a mail message and describes how mail is to be administered on the e-mail server and transmitted on the Internet.
A) Multipurpose Internet Mail Extensions (MIME)
B) Simple Mail Transfer Protocol (SMTP)
C) Interactive Mail Access Protocol (IMAP)
D) Post Office Protocol (POP)

Accepted Answer

SMTP is the protocol used for transmitting email messages over the Internet. It specifies the format of a mail message and the rules for how mail is to be administered on the email server. MIME is used for encoding attachments and multimedia content within a message, while IMAP and POP are protocols used for accessing email messages stored on a server.

Question 9

In subnetting, a computer called a _____ device converts private IP addresses into normal IP addresses when it forwards packets from those computers to the Internet.
A) Network Address Translation (NAT)
B) Network Interface Controller (NIC)
C) Generic Routing Encapsulation (GRE)
D) Data Circuit-Terminating (DCE)

Accepted Answer

Network Address Translation (NAT) is the device that converts private IP addresses into normal IP addresses when packets are forwarded from computers to the Internet. NAT is also responsible for translating the normal IP addresses of incoming packets into the private IP addresses of the appropriate computers on the local network.

Question 10

The combination of a protocol name and a domain name is called a(n) _____.
A) Uniform Resource Locator (URL)
B) Internationalized Resource Identifier (IRI)
C) Extensible Resource Descriptor Sequence (XRDS)
D) Extensible Resource Identifier (XRI)

Accepted Answer

A Uniform Resource Locator (URL) is the combination of a protocol name and a domain name. An IRI is a more advanced form of a URL that can include non-Latin characters, but it includes the protocol name and domain name. XRDS and XRI are not commonly used terms in the context of URLs.

Question 11

The computers that decide how best to forward each packet from one network to another are called _____.
A) switches
B) bridges
C) routers
D) repeaters

Accepted Answer

Routers are specifically designed to forward packets between networks based on the best possible path, using complex algorithms and protocols to make decisions about how to send packets to their destination. Switches and bridges are more commonly used to connect devices within a single network, while repeaters are used to boost the strength of a signal over a long distance.

Question 12

A _____ is a collection of rules for formatting, ordering, and error checking data sent across a network.
A) style sheet
B) semantic
C) protocol
D) packet

Accepted Answer

A protocol is a set of rules that governs the communication between devices on a network. It specifies the format, timing, sequencing, and error checking requirements for data exchange. Examples of network protocols include TCP/IP, HTTP, FTP, and SMTP.

Question 13

_____ is a connection that uses public networks and their protocols to send data using a technology called IP tunneling.
A) A personal area network
B) The Internet
C) A virtual private network
D) The World Wide Web

Accepted Answer

A virtual private network (VPN) is a connection that uses public networks, such as the Internet, and their protocols to create a secure and private connection between two or more devices. This is done using a technology called IP tunneling, which encapsulates and encrypts data to ensure privacy and security as it travels over the public network.

Question 14

SGML offers a system of marking up documents that is independent of any software application.

Accepted Answer

SGML (Standard Generalized Markup Language) is a markup language that provides a system of marking up documents. It is independent of any software application and can be used with a variety of document creation and management tools.

Question 15

A hierarchical hyperlink structure resembles conventional paper documents in that the reader begins on the first page and clicks the Next button to move to the next page in a serial fashion.

Accepted Answer

A hierarchical hyperlink structure allows users to navigate through information in a non-linear way, unlike conventional paper documents which are read in a linear fashion from the first page to the last.

Question 16

The purpose of a(n) _____ is to respond to requests for Web pages from Web clients.
A) DNS server
B) e-mail server
C) Web server
D) database server

Accepted Answer

A Web server is specifically designed to respond to requests for Web pages from Web clients. DNS servers handle domain name resolution, e-mail servers handle sending and receiving e-mails, and database servers handle storing and retrieving data from databases.

A) IP address
B) NSAP address
C) MAC address
D) OUI address

Accepted Answer

The 32-bit number used to identify computers connected to the Internet is known as an IP address. NSAP address is used in OSI networks, MAC address is a hardware address used to identify network devices, and OUI address is the first three bytes of a MAC address that identifies the manufacturer of a network device.

A) Routers
B) Semantics
C) Protocols
D) Switches

Accepted Answer

Protocols determine the rules and procedures for communication between devices on a network, including how a sending device signals the end of a message and how a receiving device acknowledges receipt of the message.

Question 20

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

The term "cascading" refers to the way style rules cascade down from one style sheet to another, allowing designers to apply multiple style sheets to the same Web page.
