B)groups make most of the routine and easy decisions in organizations.
C)organizational decision making is difficult when team members are geographically spread out and working in different time zones.
D)nearly 87 percent of employees around the world work in remote offices.

Accepted Answer

While people working together and sharing documents, difficulties in geographically dispersed decision-making, and a large portion of employees working in remote offices are all driving factors for messaging and collaboration, the statement "groups make most of the routine and easy decisions in organizations" is not a driving factor for messaging and collaboration.

Question 3

Transmission of a signal over a series of networks is made possible by switches and routers,which are hardware devices,and nodes on the network.

Accepted Answer

Switches and routers are hardware devices that enable signal transmission over networks, and nodes are the endpoints of the network.

Question 5

According to the Cellular Telecommunications Industry Association,__________ is "a way of measuring the quantity of radio frequency energy that is absorbed by the body."
A)RF rate
B)carbon footprint
C)radiation rate
D)specific absorption rate (SAR)

Accepted Answer

The statement describes specific absorption rate (SAR), which is a measure of the amount of radio frequency energy absorbed by the body when using a mobile device. The other options are not directly related to this concept.

Question 6

The 802.11b standard improves upon other 802.11 Wi-Fi standards by adding multiple-input multiple-output (MIMO)and many other newer features.

Accepted Answer

The 802.11b standard is actually an older Wi-Fi standard and does not include multiple-input multiple-output (MIMO) or other newer features.

Question 7

A centralized organization is more responsive to opportunities and problems than a decentralized organization where senior managers,who are less involved in daily operations than lower-level managers,make decisions.

Accepted Answer

In a decentralized organization, lower-level managers have more autonomy and are closer to daily operations, so they can respond more quickly and effectively to opportunities and problems. Centralized organizations tend to have a more rigid decision-making process that can slow down responsiveness.

Question 8

Pressures to deliver secure service to customers and business partners at reduced costs,to be environmentally responsible,and to support the 24/7 data needs of mobile and remote workers have all increased the demands on corporate networks.

Accepted Answer

The statement is true.

Question 9

An enterprise's network capability will be unreliable or deteriorate without proper planning,maintenance,management,upgrades,and bandwidth of the network to insure that it has sufficient capacity and connectivity to link people,locations,and data.

Accepted Answer

Proper planning, maintenance, management, upgrades, and bandwidth are essential for ensuring the reliability and efficiency of an enterprise's network capability. Without these factors, the network may experience downtime, slow performance, and other issues that can negatively impact productivity and profitability.

Question 10

TCP/IP was created by the U.S.Department of Defense to ensure and preserve data security and control communications in the event of catastrophic war.

Accepted Answer

The answer of TCP/IP was created by the U.S.Department of...

Question 11

Messaging and collaboration tools include older communications media such as e-mail,videoconferencing,fax,and IM-and Web 2.0 media such as blogs,podcasts,RSS,wikis,and VoIP.

Accepted Answer

The statement is true, as it correctly lists both older and newer forms of messaging and collaboration tools.

Question 12

Apple's first 4G phone,the HTC EVO 4G was released in summer 2010 with speeds 10 times greater than 3G phones.

Accepted Answer

The HTC EVO 4G was actually released by HTC, not Apple.

Question 13

Users can get 4G wireless connectivity through one of two standards: WiMAX or LTE.

Accepted Answer

WiMAX and LTE are both capable of providing 4G wireless connectivity.

Question 14

Wireless networks use packet switching and wireless routers to forward packets from one network to another network.

Accepted Answer

Wireless networks do use packet switching and wireless routers to forward packets between networks.

Question 15

The distinguishing characteristic of packet switching is that once a connection is made between the source and destination,the path of the signal along the nodes is dedicated and exclusive.

Accepted Answer

The distinguishing characteristic of packet switching is that the data is broken up into packets, which can take different paths and be interleaved with packets from other connections, allowing for more efficient use of network resources.

Question 16

__________ shows the power of the individual in the connected age-a better research tool than major corporations had in the 1990s.
A)Facebook
B)Google
C)Microsoft
D)eBay

Accepted Answer

Google is a powerful research tool that allows individuals to access vast amounts of information quickly and easily. In the 1990s, major corporations had expensive and limited access to information databases, while now individuals can perform searches for free. Facebook and eBay are not specifically research-oriented and Microsoft, while a major player in technology, does not have the same search capabilities as Google.

Question 17

IP networks form the backbone of worldwide digital networking and enable the convergence of voice,data,and video.

Accepted Answer

IP networks allow different types of communication (voice, data, video) to be transmitted over a single network, enabling seamless connectivity and convergence.

Question 18

Which of the following is a dysfunction of the group process?
A)Social pressures of conformity can lead to groupthink.
B)A group may produce synergy during problem solving.
C)Group members may have their egos embedded in the decision,and so they may be committed to the solution.
D)Groups are better than individuals at understanding problems.

Accepted Answer

Groupthink is a dysfunction of the group process where individual members prioritize conformity and harmony over critical evaluation of ideas, leading to flawed decision-making. The other options are examples of positive group processes.

Question 19

Bandwidth is the throughput capacity,or speed,of a network,which depends on what protocol is used.

Accepted Answer

Bandwidth is indeed the throughput capacity or speed of a network, which is affected by various factors including the protocol used.

Question 20

Network performance is measured by its data transfer capacity.

Accepted Answer

Network performance is typically measured by metrics such as throughput, latency, packet loss, and bandwidth, all of which are related to the data transfer capacity of the network. Therefore, the statement is true.
