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.

Question 8Select one:

A.
jam

B.
crash

C.
hit

D.

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.
