Question 1

A network is fundamentally a communication system.

Accepted Answer

A network is designed to facilitate communication between devices, allowing them to exchange data and resources.

Question 2

When you talk to someone, the transmission medium is your voice.

Accepted Answer

The transmission medium is the air through which the sound waves of your voice travel.

Question 3

A faster frequency means a slower data transmission rate.

Accepted Answer

A faster frequency typically means a higher data transmission rate, as more data can be transmitted in a given amount of time.

Question 4

The FCC has defined broadband as faster than 200 Kbps. Almost everyone today would consider 200 Kbps to be an extremely fast connection.

Accepted Answer

The FCC currently defines broadband as having a minimum download speed of 25 Mbps, and 200 Kbps is considered very slow by today's standards.

Question 5

Coaxial cable is slower than Cat 1 and 2 twisted pair copper cables.

Accepted Answer

Coaxial cables generally have higher bandwidth and can support faster data transmission speeds compared to Cat 1 and 2 twisted pair copper cables, which are older and designed for lower-speed applications.

Question 6

Wireless phone conversations, wireless computer networks, global positioning systems, police and emergency communications, satellite communications, and wireless clock systems all make use of radio waves.

Accepted Answer

Radio waves are a type of electromagnetic radiation used for various forms of wireless communication, including those mentioned.

Question 7

Microwave signals are used for high-speed, high-capacity communication links and satellite communications.

Accepted Answer

Microwave signals have high frequencies that allow them to carry large amounts of data over long distances, making them suitable for high-speed communication and satellite links.

Question 8

Hubs and switches are seldom combined.

Accepted Answer

Hubs and switches are often combined in network setups to optimize performance and connectivity, with switches providing more efficient data handling and hubs offering basic connectivity.

Question 9

Microwave transmission is also called orbital microwave.

Accepted Answer

Microwave transmission is not referred to as orbital microwave; it typically involves the transmission of signals via microwave frequencies through the atmosphere, not involving orbital paths.

Question 10

A microwave link can carry a large percentage of the capacity of a fiber-optic strand.

Accepted Answer

Fiber-optic strands have a much higher capacity for data transmission compared to microwave links, which are limited by bandwidth and environmental factors.

Question 11

T3 lines carry 72 signals on one line and are used by telecommunications companies.

Accepted Answer

The answer of T3 lines carry 72 signals on one...

Question 12

A large organization might employ dozens of network administrators.

Accepted Answer

Large organizations often have complex and extensive networks that require multiple network administrators to manage and maintain them effectively.

Question 13

A network operating system performs the same types of functions for the network as operating system software performs for a computer.

Accepted Answer

A network operating system manages network resources and provides services such as file sharing, printer access, and network security, similar to how an operating system manages resources and services on a single computer.

Question 14

A token ring is compatible with Ethernet.

Accepted Answer

Token ring and Ethernet are two different network protocols with distinct architectures and are not directly compatible without specific bridging or conversion equipment.

Question 15

Each cell tower has a transmission and receiving range of 3-15 miles depending on geography and environment.

Accepted Answer

Cell towers typically have a range that can vary from 3 to 15 miles, influenced by factors such as terrain, urban density, and environmental conditions.

Question 16

Today's cell phone networks are nearly all digital.

Accepted Answer

Most modern cell phone networks use digital technology for communication, as it allows for more efficient use of bandwidth and provides better quality and security compared to analog systems.

Question 17

Areas around access points where users can connect to the Internet are often called warmspots.

Accepted Answer

Areas around access points where users can connect to the Internet are commonly referred to as "hotspots," not "warmspots."

Question 18

There are more wide area networks than any other network type.

Accepted Answer

Local area networks (LANs) are more common than wide area networks (WANs) because they are used in smaller, localized settings like homes, schools, and businesses.

Question 19

A wide area network (WAN) connects LANs and MANs between cities, across country, and around the world using microwave and satellite transmission or telephone lines.

Accepted Answer

A WAN connects multiple LANs and MANs over large geographical areas using various transmission methods like microwave, satellite, and telephone lines.

Question 20

Governments and companies can avoid their own country's laws by processing data within the boundaries of other countries, sometimes called data havens, that have few restrictions on telecommunications or databases.

Accepted Answer

Some countries have lax data protection laws, allowing governments and companies to process data there to circumvent stricter regulations in their own countries.
