All of the choices are examples of 3G technologies. EDGE (Enhanced Data rates for GSM Evolution) is a technology used in GSM mobile networks to increase data transfer rates. EV-DO (Evolution-Data Optimized) is a technology used in CDMA mobile networks for high-speed wireless data transfer. HSUPA (High-Speed Uplink Packet Access) is a technology used in the UMTS mobile network to increase data transmission speeds.

Question 9

Satellite data transport is subject to ____ delays of one second or more,which occur as your data is routed between your computer and a satellite that orbits 22,200 miles above the Earth.
A) latency
B) conditional
C) frequency
D) concatenation

Accepted Answer

The term for delays in satellite data transport is latency, which can be one second or more due to the distance between the satellite and Earth. Conditional, frequency, and concatenation are not relevant to this concept.

Question 14

Cable Internet service needs ____.
A) circuitry to handle Ethernet protocols and a cable modem
B) a cable modem and router
C) Internet protocols and a cable modem
D) a cable modem and phone lines

Accepted Answer

Cable Internet service requires circuitry to handle Ethernet protocols and a cable modem to connect to the network. A router may also be necessary to distribute the Internet connection to multiple devices. Internet protocols are not needed as they are part of the standard Internet infrastructure. Phone lines are not used for Cable Internet service.

Question 15

____ wireless Internet service is designed to offer Internet access to homes and businesses by broadcasting data signals over areas large enough to cover most cities and outlying areas.
A) Mobile
B) Cellular
C) WiFi
D) Fixed

Accepted Answer

Fixed wireless Internet service typically uses radio waves to provide high-speed Internet access to a fixed location. It is more reliable and offers faster speeds than mobile or cellular networks, making it a better choice for homes and businesses where a consistent and stable Internet connection is required. WiFi, on the other hand, is a local wireless network that provides Internet access only within a limited range, such as a home or office, and requires a wired broadband connection.

Question 16

____ is an up-and-coming standard destined to be deployed by ISPs and cell phone carriers to allow seamless handoff between one tower and another.
A) WiMAX
B) Mobile WiMAX
C) Portable WiMAX
D) Mobile WiFi

Accepted Answer

Mobile WiMAX is designed to support mobile internet access and allow seamless handoff between one tower and another while in motion, making it the best option for the given scenario. WiMAX and Portable WiMAX are stationary technologies, while Mobile WiFi refers to the ability to create a personal Wi-Fi hotspot using a mobile device.

A) WAP
B) WIP
C) HAP
D) HIP

Accepted Answer

WAP (Wireless Application Protocol) is a communications protocol that provides Internet access from handheld devices, such as mobile phones or PDAs. WIP, HAP, and HIP are not established protocols for Internet access from handheld devices.

Question 20

With ____ you can easily assemble a small network just about anywhere.
A) RF
B) MiFi
C) EVDO
D) All of the above

Accepted Answer

MiFi is a portable wireless hotspot that allows multiple devices to connect to the internet through cellular data. It is convenient for assembling a small network in remote locations or areas without access to traditional Wi-Fi. RF refers to radio frequency, which is a type of wireless communication that can also be used for networking but would require additional equipment and configuration. EVDO is a type of cellular data network that could be used for internet access, but again, would require additional equipment and may not be as convenient as the MiFi hotspot. Therefore, B is the best choice for easily assembling a small network anywhere.
