Question 1

Any computer that stores hypermedia documents and makes them available to other computers on the Internet is called a _____.
A) client
B) server
C) station
D) domain

Accepted Answer

A server is a computer dedicated to storing and sharing resources with other computers on a network or on the Internet. In this case, a server is specifically designed to store hypermedia documents and make them available to other computers online. Clients, stations, and domains do not necessarily serve this purpose.

Question 2

The Internet backbone is a foundation network linked with _____ that can support very high bandwidth.
A) fiber-optic cables
B) coaxial cables
C) heliax cables
D) twisted pair cables

Accepted Answer

Fiber-optic cables are the most common type of cables used in the Internet backbone because they allow for high-speed data transmission over long distances without experiencing signal degradation. Coaxial cables and twisted pair cables, on the other hand, have lower bandwidth capacity and are more suitable for shorter distances. Heliax cables are a type of coaxial cable designed for higher frequencies but are not commonly used in the Internet backbone.

Question 3

The World Wide Web changed the Internet by introducing a graphical interface to the largely text-based Internet.

Accepted Answer

The World Wide Web (WWW) is a platform that introduced a graphical interface to the Internet, making it more user-friendly and accessible to the general public. Prior to the WWW, the Internet was largely text-based, with users accessing information through a command-line interface. The introduction of graphical web browsers such as Netscape Navigator and later, Internet Explorer, made it possible to navigate the Internet through a graphical interface with images, links, and multimedia content.

Question 4

In the context of directories on the Web, Open Directory is an example of an automated directory.

Accepted Answer

Open Directory, also known as DMOZ (Directory Mozilla), was a human-edited directory where websites were organized into categories by volunteer editors, not automatically by algorithms.

Question 5

Even if there are more than one smart object on an individual's body, they would not be aware of each other's existence.

Accepted Answer

Smart objects are not conscious and do not have the ability to communicate with each other, so an individual would not be aware of multiple smart objects on their body even if they were present.

Question 6

_____ are unique identifiers of computer or network addresses on the Internet.
A) Domain names
B) Prototypes
C) Foreign keys
D) Mirror disks

Accepted Answer

Domain names are unique identifiers of computer or network addresses on the internet. They are used in URLs to identify particular web pages or websites. Prototypes are early sample versions of a product, foreign keys are used in relational databases to establish links between different tables, and mirror disks are used for backup or redundancy purposes in computer systems.

Question 7

An intranet is an application or service that uses an organization's computer network.

Accepted Answer

An intranet is a network that is used within an organization to share information, applications or operational systems. It is not accessible to the public, and is accessed using a secure login by employees, contractors or others who have access to the system. Therefore, it is an application or service that uses an organization's computer network.

Question 8

Online degree programs adversely affect colleges and universities that are facing an enrollment decline.

Accepted Answer

Online degree programs can actually help colleges and universities facing an enrollment decline by expanding their reach to non-traditional students, those who need flexibility, and international students, potentially increasing enrollment numbers.

Question 9

Intranets are typically set up behind a firewall.

Accepted Answer

Intranets are typically set up behind a firewall to protect and secure internal company information and data. The firewall controls access to the intranet and helps prevent unauthorized access from external sources.

Question 10

The Web organizes information by using _____, meaning documents that include embedded references to audio, text, images, video, or other documents.
A) spyware
B) hypermedia
C) newsgroups
D) adware

Accepted Answer

The term that best fits the description is "hypermedia." Hypermedia refers to documents that contain embedded references to various forms of media, allowing users to easily navigate and access different types of information. Spyware and adware are types of malicious software, while newsgroups are discussion forums for specific topics.

Question 11

Client-based e-mail enables a user to access his or her e-mail account from any computer.

Accepted Answer

Client-based email requires the installation of email software on the user's computer, limiting access to the email account to computers that have the specific email client installed and configured.

Question 12

Hypermedia documents can be stored anywhere in the world.

Accepted Answer

Hypermedia documents can be stored anywhere in the world and accessed through the internet.

Question 13

James gets a job at a multinational corporation. On his first day at work, he finds out that the numerical code assigned by the Internet Corporation for Assigned Names and Numbers (ICANN) to his computer system is 115.248.178.233. This numerical code is referred to as a(n) _____.
A) Internet Protocol address
B) virtual path identifier
C) Ethernet address
D) data link connection identifier

Accepted Answer

The numerical code assigned by ICANN to James' computer system is an Internet Protocol (IP) address, which is a unique identifier assigned to devices connected to the internet. Virtual path identifier (VPI), Ethernet address, and data link connection identifier (DLCI) are all different types of network identifiers, but they do not refer to the specific numerical code assigned by ICANN to James' computer.

Question 14

A T3 line uses two pairs of copper wires to carry up to 24 simultaneous conversations and has a transmission rate of 1.544 Mbps.

Accepted Answer

A T3 line uses 28 pairs of copper wires to carry data at a rate of 45 Mbps, not 1.544 Mbps. It is primarily used for high-speed internet connections and can handle large amounts of data traffic.

Question 15

Voice over Internet Protocol (VoIP) is used to route traffic starting and ending at conventional public switched telephone network phones.

Accepted Answer

VoIP allows calls to be transmitted over the internet, enabling communication between traditional PSTN phones and other VoIP devices.

Question 16

Combinations of spaces and special characters can be used in domain names of uniform resource locators (URLs).

Accepted Answer

Spaces and special characters are generally not allowed in domain names of URLs. Only letters, numbers, and hyphens are allowed.

Question 17

Telepresence surgery allows surgeons to operate all over the world without physically traveling anywhere.

Accepted Answer

Telepresence surgery, also known as remote surgery, enables surgeons to perform surgeries on patients in remote locations using robotic technology, high-speed communication networks, and advanced computer systems. This eliminates the need for physical travel, making it a real possibility for global healthcare.

Question 18

Any computer that stores hypermedia documents and makes them available to other computers on the Internet is called a client.

Accepted Answer

The statement is incorrect. Such a computer is called a server, not a client.

Question 19

In the context of directories on the Web, a human-powered directory uses crawlers to collect data.

Accepted Answer

A human-powered directory relies on humans to categorize and organize website listings, whereas a crawler-powered directory uses automated programs to collect website data.

Question 20

The Internet is owned by the Advanced Research Projects Agency Network (ARPANET).

Accepted Answer

ARPANET was the precursor to the Internet and was developed in the late 1960s by the United States Department of Defense. The Internet is a global network of interconnected computers and is not owned by any one organization or government.
