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.

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: 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: Data flows in both directions in a ring network.
Question 24Select one:
True
False
Assistant: False

In a traditional ring network, data flows in one direction around the ring to each device until it reaches its destination. However, there are variations, such as dual-ring networks, where data can flow in both directions to provide redundancy and increased reliability. But in the basic form of a ring network, data typically flows in a single direction.
