IPv7 and IPv6

C.
Wi-Fi and Bluetooth

D.
ROVER-5 and ethernet
Assistant: C. Wi-Fi and Bluetooth

Cars often have Wi-Fi and Bluetooth networks to enable connectivity for various devices, allowing features such as hands-free calling, audio streaming, internet access, and the use of various connected services.
User: A ________ enables your computer to connect to other computers or to the Internet.
Question 3Select one:

A.
controller card

B.
network interface card (NIC)

C.
sound card

D.
video card
Assistant: B. network interface card (NIC)

A network interface card (NIC) enables your computer to connect to other computers or to the Internet. It is an essential component for establishing network connections and facilitating communication between devices on a network.
User: A computer connected to the Internet that asks for data is a(n) ________.
Question 4Select one:

A.
aggregator

B.
surrogate

C.
client

D.
server
Assistant: C. client

A computer connected to the Internet that asks for data is a client. In a client-server architecture, the client requests services or resources from another computer, known as the server, which provides or hosts the data.
User: A ________ sends information between two networks.
Question 5Select one:

A.
repeater

B.
bridge

C.
switch

D.
router
Assistant: D. router

A router sends information between two networks. It directs data packets between devices and networks, determining the best path for the data to travel across the network, and is essential for connecting different networks, such as a home network to the Internet.
User: Wireless access points can provide coverage wherever employees are working with portable devices, such as in conference rooms.
Question 6Select one:
True
False
Assistant: True

Wireless access points can indeed provide coverage wherever employees are working with portable devices, such as in conference rooms. They extend the range of a wired network wirelessly, allowing devices to connect to the network without requiring a direct wired connection, which is particularly useful in environments where mobility and flexibility are important.
User: In a client/server network, each network node communicates directly with every other node on the network.
Question 7Select one:
True
False
Assistant: False

In a client/server network, each network node does not communicate directly with every other node. Instead, clients communicate with a central server that provides resources or services. The server manages network resources, and clients make requests to the server rather than directly to each other, which is the main characteristic of a client/server network as opposed to a peer-to-peer network where nodes communicate directly with each other.
User: In an Ethernet network, the signal that is sent to indicate a signal collision is called a ________ signal.
Question 8Select one:

A.
jam

B.
crash

C.
hit

D.
stop
Assistant: A. jam

In an Ethernet network, the signal that is sent to indicate a signal collision is called a jam signal. When a collision is detected, devices send this signal to inform all nodes that a collision has occurred, which stops transmission until a retransmission opportunity arises.
User: E-mails are completely private.
Question 9Select one:
True
False
Assistant: False

E-mails are not completely private. They can potentially be accessed by unauthorized parties through various means such as hacking, interception while in transit, or by being stored on servers. Moreover, email administrators and service providers may have access to the contents of emails. Therefore, it's important to use encryption and other security measures to enhance the privacy of email communications.
User: Which of the following is NOT a social networking site?
Question 10Select one:

A.
iTunes

B.
LinkedIn

C.
Facebook

D.
YouTube
Assistant: A. iTunes

iTunes is not a social networking site. It is a media player and media library application developed by Apple Inc., used for playing, downloading, and organizing digital multimedia, such as music and videos. In contrast, LinkedIn, Facebook, and YouTube all involve social networking or community engagement functionalities.
User: A bridge sends information between two networks.
Question 11Select one:
True
False
Assistant: True

A bridge connects two or more networks and forwards data between them. It operates at the data link layer (Layer 2) and is used to divide larger networks into smaller segments, helping to reduce network traffic and improve performance by filtering and forwarding traffic based on MAC addresses. However, unlike routers, bridges do not determine optimal paths for data across networks.
User: MAC addresses and IP addresses are the same thing.
Question 12Select one:
True
False
Assistant: False

MAC addresses and IP addresses are not the same thing. A MAC (Media Access Control) address is a unique identifier assigned to a network interface card (NIC) for communication on the physical network segment. It operates at the data link layer of the OSI model. An IP (Internet Protocol) address, on the other hand, is used to identify a device on a network at the network layer, allowing for routing and communication over interconnected networks such as the internet. While MAC addresses are hardware-specific and typically remain constant, IP addresses can change and are assigned logically depending on the network configuration.
User: Which of the following is the most commonly used client/server network topology?
Question 13Select one:

A.
Ring

B.
Star

C.
Cluster

D.
Hierarchical
Assistant: B. Star

The star topology is the most commonly used client/server network topology. In a star network, all nodes are connected to a central hub or switch, which facilitates communication between them. This topology is favored for its simplicity, ease of management, and scalability. It also allows for easy isolation of devices without affecting the rest of the network.
User: Which of the following is NOT a factor to consider when selecting network cabling?
Question 14Select one:

A.
Interference

B.
Bandwidth

C.
Cable diameter

D.
Maximum run length
Assistant:
