Question 12

In grid computing, each participant is referred to as a branch.

Accepted Answer

In grid computing, each participant is referred to as a node or a grid node.

Question 13

Compared with Worldwide Interoperability for Microwave Access (WiMAX), Wireless Fidelity (Wi-Fi) theoretically has faster data transfer rates and a longer range.

Accepted Answer

This statement is false. WiMAX theoretically has faster data transfer rates and a longer range compared to Wi-Fi. WiMAX can offer speeds up to 70 Mbps and has a range of up to 50 km, while Wi-Fi typically has a range of up to 100 meters and speeds up to 1 Gbps.

Question 14

In an exocentric environment of virtual reality (VR), users can interact with objects.

Accepted Answer

The answer of In an exocentric environment of virtual reality...

Question 15

People can enter other cave automatic virtual environments (CAVEs) in other locations, no matter how far away they are geographically.

Accepted Answer

This is possible through the use of networked CAVE systems that allow users to connect and interact in virtual environments from different locations.

Question 16

With _____, a Web server delivers information to users, who have signed up for the service, instead of waiting for them to request the information be sent to them.
A) push technology
B) pull technology
C) virtual reality technology
D) radio frequency identification technology

Accepted Answer

Push technology involves a Web server delivering information directly to users who have signed up for the service, without them having to actively request it. This differs from pull technology, where users actively request the information themselves. Virtual reality technology and radio frequency identification technology are unrelated to this concept.

Question 17

Nanomaterials have been applied as coatings on eyewear for increased comfort.

Accepted Answer

Nanomaterials have been used as coatings on eyewear to improve comfort, durability, and performance. These coatings can provide benefits such as scratch resistance, anti-fog properties, and UV protection.

Question 18

With the _____, users do not need to be concerned with new software versions and compatibility problems because the application service providers (ASPs) offer the most recent version of the software.
A) software distribution model
B) software as a service model
C) radio frequency identification model
D) automatic virtual environment model

Accepted Answer

The statement is describing the software as a service (SaaS) model, where the software is hosted and provided by application service providers (ASPs) and users access it through the internet. With this model, ASPs ensure that users have access to the most recent version of the software without having to deal with compatibility issues or software updates.

Question 19

In virtual environment (VR) terminology, the everyday physical world is referred to as a "micro environment."

Accepted Answer

In VR terminology, the everyday physical world is referred to as the "real world" or "physical environment." The term "micro environment" is not commonly used in this context.

Question 20

Ziffcorp, an IT firm, uses a technology that automatically updates the antivirus software in all the computers in the firm whenever the software becomes outdated. It is evident that Ziffcorp uses _____ for automatically updating the antivirus software.
