Question 1

One major obstacle to using virtual reality (VR) technology is that not enough _____ are currently available to carry out the data transmissions needed for a VR environment capable of re-creating a conference.
A) avatars
B) quick response codes
C) fiber optic cables
D) nanomaterials

Accepted Answer

Fiber optic cables are crucial for high-speed data transmission, which is necessary for creating and maintaining a seamless virtual reality environment. Avatars are virtual representations of oneself, and while they are necessary for VR interaction, they do not determine the quality of the data transmission. Quick response codes and nanomaterials are unrelated to VR technology and data transmission.

Question 2

In the context of virtual reality (VR) technology,_____ refers to giving users the sense that they are in another location,even one geographically far away,and can manipulate objects as though they are actually in that location.
A) interaction
B) simulation
C) telepresence
D) immersion

Accepted Answer

Telepresence refers to the feeling of being present in another location and being able to interact with it. It involves the use of VR technology to create a realistic and immersive experience that gives users the sensation of being in that location. Telepresence is a key component of VR technology, as it allows users to experience things that are beyond their physical reach.

Question 5

_____ radio frequency identification (RFID) tags have no internal power supply.
A) Active
B) Passive
C) Open
D) Closed

Accepted Answer

A head-mounted display (HMD) is typically used in an egocentric virtual environment to provide a first-person perspective and immerse the user in the virtual world. Nanotechnology and software as a service (SaaS) are not commonly used in this context, while 3D graphics may be used in combination with the HMD to create a more realistic virtual environment. However, the HMD is the most essential technology for an egocentric virtual environment.

Question 7

In the context of virtual reality (VR) technology,the main technology used in an exocentric environment is _____.
A) WiMAX
B) QR code
C) nanotechnology
D) 3D graphics

Accepted Answer

In the context of virtual reality technology, an exocentric environment refers to an environment where the user is an external observer rather than being part of the scene. The main technology used in exocentric VR environments is 3D graphics, which create a simulated world for the user to observe and interact with. WiMAX is a wireless communication technology, QR code is a type of barcode used for identification, and nanotechnology refers to the manipulation of matter on an atomic and molecular scale - none of which are directly related to exocentric VR environments.

Question 8

In the context of virtual reality (VR) technology,_____ refers to allowing users in different locations to interact and manipulate the same world at the same time by connecting two or more virtual worlds.
A) networked communication
B) full-body immersion
C) telepresence
D) interaction

Accepted Answer

Networked communication refers to the ability to connect users in different locations, allowing them to interact and manipulate the same virtual world simultaneously. This is key to enabling social interaction and collaboration in virtual reality.

Question 9

A(n) _____ is a matrix barcode consisting of black modules arranged in a square pattern on a white background.
A) radio frequency identification (RFID) tag
B) QR (quick response) code
C) latent image barcode
D) telepen code

Accepted Answer

The description matches that of a QR (quick response) code, which is a two-dimensional barcode consisting of black squares on a white background. The pattern can be scanned by a smartphone camera or barcode scanner to quickly access information, such as a website or product details. The other options do not fit the description given.

Question 10

Bluetooth can be used to create a _____,to communicate among computerized devices.
A) personal area network (PAN)
B) local area network (LAN)
C) wide area network (WAN)
D) metropolitan area network (MAN)

Accepted Answer

Bluetooth is a technology used to create a personal area network (PAN), which is a network of devices such as smartphones, tablets, laptops, and wearable devices connected to each other within a short distance of typically 10 meters or less. Therefore, option A is the correct answer. Options B, C, and D are not appropriate as they refer to larger networks that cover larger distances, such as local area networks (LANs), wide area networks (WANs), or metropolitan area networks (MANs).

Question 11

_____ is a small electronic device consisting of a microchip and an antenna and performs the same task as bar codes.
A) Bluetooth
B) A monitoring and surveillance agent
C) Nanomaterial
D) A radio frequency identification tag

Accepted Answer

A radio frequency identification tag, also known as an RFID tag, is a small electronic device consisting of a microchip and an antenna. It performs the same task as barcodes, which is to provide identification or tracking information, but has the added advantage of being able to be read from a distance without requiring line-of-sight scanning. Bluetooth is a wireless technology for exchanging data over short distances, Nanomaterial is a material with a structure or elements smaller than 100 nanometers, and a monitoring and surveillance agent is a type of software or hardware designed to monitor and track activities.

Question 15

Which of the following technologies could be used to prevent one coworker from checking in for another in an organization?
A) Biometrics
B) Nanotechnology
C) Bluetooth
D) Grid computing

Accepted Answer

Biometrics technology can verify the identity of an individual through their unique biological characteristics such as fingerprints, iris scans, and facial recognition. This can prevent one coworker from checking in for another as their biometric data would not match. Nanotechnology, Bluetooth, and Grid computing are not relevant technologies for this specific use case.

Question 16

A cave automatic virtual environment (CAVE) is a virtual environment consisting of a _____ room in which the walls are rear projection screens.
A) cylindrical
B) spherical
C) cube-shaped
D) honeycomb-shaped

Question 17

The _____ component of a virtual reality (VR) system is an input device that captures and records movements of a user's feet as the user turns in different directions.
A) walker
B) crawler
C) kernel
D) fuzzy logic

Accepted Answer

A VR system typically uses a walker component as an input device to capture and record movements of a user's feet as the user turns in different directions. A walker is a device that allows users to move around in a virtual environment by walking in place or taking steps, and the movements are tracked and translated into movements in the virtual environment. The other options (B) crawler, (C) kernel, and (D) fuzzy logic are not related to the input devices used in a VR system.

Question 18

_____ radio frequency identification (RFID) tags can be embedded in a sticker or under the human or animal skin.
A) Active
B) Passive
C) Open
D) Closed

Accepted Answer

Active RFID tags have their own power source and can broadcast their signal over longer distances, making them ideal for being embedded under skin or within stickers. Passive RFID tags rely on external signals and have short detection ranges, making them less suitable for these applications. Open and closed do not apply to RFID tags.

Question 19

Users interact via avatars in a(n) _____.
A) public cloud
B) virtual world
C) artificial neural network
D) knowledge acquisition facility

Accepted Answer

Avatars are typically used in virtual worlds where users interact with each other through their digital representations. Public cloud refers to a type of cloud computing infrastructure, artificial neural network refers to a machine learning technology, and knowledge acquisition facility pertains to a tool or process for gathering knowledge or data.

Question 20

An advantage of grid computing is _____,meaning that if one node on the grid fails,another node can take over.
A) improved reliability
B) parallel processing
C) scalability
D) simulation

Accepted Answer

Improved reliability is the advantage of grid computing in which if one node on the grid fails, another node can take over. This helps in ensuring continued availability and efficient use of resources. Parallel processing, scalability, and simulation are also advantages of grid computing, but they are not specific to the scenario mentioned in the question.
