Question 1

One new improvement to videoconferencing technology to make it more closely mimic a real-time meeting environment is ____ videoconferencing.

Accepted Answer

Telepresence videoconferencing uses advanced audio and visual technology to create a more immersive and realistic experience similar to an in-person meeting. It includes features such as high-definition video, spatial audio, and life-sized screens to give the impression that remote participants are physically present in the room.

Question 2

Developed in the late 1990s, Wi-Fi (for wireless fidelity)is a family of wireless networking standards that use the IEEE standard ____.

Accepted Answer

Wi-Fi networking standards use the IEEE standard 802.11.

Question 3

With holographic storage systems, the signal beam passes through a device called a ____ light modulator (SLM), which translates the data's 0s and 1s into a hologram.

Accepted Answer

The correct term to fill in the blank is "spatial light modulator" (SLM). This device is responsible for translating the data into a hologram by modulating the intensity and phase of the signal beam at different points in space. The other answer choices (A, B, and D) do not accurately describe the device used in holographic storage systems.

Question 4

Today's holographic storage systems typically consist of a holographic drive and removable recordable holographic discs, with current capacities ranging from 300 GB to ____ GB per cartridge.

Accepted Answer

Current capacities range from 300 GB to 500 GB per cartridge.

Question 5

____ applications that exist in some form today include intelligent agents, expert systems, neural networks, and robotics.

Accepted Answer

The applications listed, such as intelligent agents, expert systems, neural networks, and robotics, are all examples of artificial intelligence (AI) technology. Therefore, the best choice is B, Artificial intelligence.

Question 6

To record data, holographic storage systems split the light from a blue laser beam into two beams-a ____ beam whose angle determines the address used to store data at that particular location on the storage medium and a signal beam that contains the data.

Accepted Answer

The description matches a reference beam, which is used to determine the address for storing data in a certain location. The other answer choices do not accurately describe this process.

Question 7

Designed initially for mobile phones and other portable devices, an IMOD screen is essentially a complex mirror that uses ____ light to display images.

Accepted Answer

An IMOD (Interferometric Modulation) screen uses external light to display images by reflecting it, similar to how a mirror works.

Question 8

A __________ usually projects the image from a mobile device to a display screen built into the glasses via a wireless connection.

Accepted Answer

A wearable display is a type of device that can project images directly onto the glasses themselves through a wireless connection. This allows the user to view their mobile devices without having to hold them in their hands, making it a convenient and hands-free option for viewing content on-the-go. The other options, integrated projector, pico projector, and 3D printer, do not accurately describe the functionality of a wearable display.

Question 9

Self-driving cars, like Google's autonomous cars, are essentially __________.

Accepted Answer

Self-driving cars are essentially robotic cars, as they are equipped with sensors, cameras, and other technologies that allow them to navigate and drive without human input. While they may utilize neural networks, expert systems, and inference engines as components of their overall operation, the primary function of self-driving cars is to act as robotic drivers.

Question 10

While some researchers are working on developing an all-optical computer, others believe that a mix of optical and electronic components, referred to as an ____ computer, may be the best bet for the future.

Accepted Answer

The correct term for a computer that uses a mix of optical and electronic components is opto-electronic. This term describes the combination of both technologies and is commonly used in the field. Choices A, B, and D are not commonly used or recognized terms for this type of computer.

Question 11

Power over Ethernet (PoE)allows both ____ power and data to be sent over standard Ethernet cables.

Accepted Answer

Power over Ethernet (PoE) allows electrical power and data to be transmitted over standard Ethernet cables.

Question 12

The speed and distance of a Wi-Fi network depends on a variety of factors, such as the particular Wi-Fi standard and ____.

Accepted Answer

All of the factors listed (number of solid objects, interference from other devices, and hardware being used) can impact the speed and distance of a Wi-Fi network.

Question 13

____ displays are transparent; the portion of the display that does not currently have an image displayed (and the entire display device when it is off)is nearly as transparent as glass, so the user can see through the screen.

Accepted Answer

TOLED stands for Transparent Organic Light-Emitting Diode, which is specifically designed to be transparent. The other options, TLED and TDOE, are not specifically designed to be transparent and may not have the same level of transparency as a TOLED display.

Question 14

The ____ Web is a predicted evolution of the current Web in which all Web content is stored in formats that are more easily read by software applications and intelligent agents.

Accepted Answer

The Semantic Web is the predicted evolution of the current Web in which all Web content is stored in formats that are more easily read by software applications and intelligent agents. The idea is to create a smarter Web that can understand the relationships between different pieces of data and use that data to deliver more relevant results to users.

Question 15

One recent development in new technology is ____ that can remove contaminants from water sources.

Accepted Answer

Nanofilters are a new technology that can remove contaminants from water sources. They are very small and can remove particles as tiny as viruses and bacteria, making them incredibly effective at purifying water.

Question 16

Most people agree that nanotechnology involves creating computer components, machines, and other structures that are less than ____ nanometers in size.

Accepted Answer

Nanotechnology typically involves structures that are less than 100 nanometers in size, as this scale allows for manipulation of individual atoms and molecules.

Question 17

In general, Wi-Fi is designed for data transfers between ____ feet indoors.

Accepted Answer

Wi-Fi is generally designed for data transfers between 100 and 300 feet indoors. This range can vary depending on factors such as interference, obstacles, and the type of Wi-Fi router or device being used, but this is the typical range for a standard Wi-Fi network. Options A and D have too small of a range, while option B is too large.

Question 18

A(n)____ computer uses light, such as from laser beams or infrared beams, to perform digital computations.

Accepted Answer

Optical computers use light to perform digital computations, unlike digital, hybrid, or solar computers.

Question 19

The wall of a single-walled carbon nanotube is only one carbon atom thick and the tube diameter is approximately ____ times smaller than a human hair.

Accepted Answer

A single-walled carbon nanotube has a diameter of about 1 nanometer, while a human hair is approximately 100,000 nanometers thick, making the nanotube about 10,000 times smaller.

Question 20

____ is one of the Wi-Fi standards most widely used today.

Accepted Answer

All of the listed standards (802.11ac, 802.11g, and 802.11n) are widely used in various devices and networks today, with 802.11ac being the most recent and fastest among them.
