Exploring Networking Concepts

What is a network topology?

• The software applications running on a network.

• Network topology is the layout or structure of a network.

• The type of hardware used in a network.

• The speed of data transfer in a network.

Name three common types of network topologies.

• Star, Bus, Ring

• Hybrid

• Tree

• Mesh

What is the main characteristic of a star topology?

• All devices are connected to a central hub or switch.

• There is no central point of connection.

• Each device connects to every other device directly.

• All devices are connected in a linear fashion.

In a bus topology, how are devices connected?

• Devices are connected to a single central cable (the bus).

• Devices are connected wirelessly without any cables.

• Devices are connected in a star configuration.

• Devices are connected in a ring topology.

What are the advantages of a mesh topology?

• High reliability, easy fault isolation, redundancy, and high traffic handling.

• Single point of failure

• Complex installation

• Low scalability

Define wireless networking.

• Wireless networking is a method of connecting devices to a network without physical cables, using radio waves or infrared signals.

• Wireless networking is a method of connecting devices using fiber optics.

• Wireless networking is only used for mobile devices.

• Wireless networking requires physical cables for connection.

What is the purpose of a wireless access point?

• To connect multiple wired devices together.

• To amplify the signal of a wired network.

• To provide wireless connectivity to devices and connect them to a wired network.

• To provide a direct internet connection without any devices.

What frequency bands are commonly used in Wi-Fi networks?

• 2.4 MHz, 5.8 MHz, and 6.2 MHz

• 2.4 GHz, 5 GHz, and 6 GHz

• 2.0 GHz, 4.0 GHz, and 8.0 GHz

• 1.2 GHz, 3.5 GHz, and 7 GHz

What is the difference between 2.4 GHz and 5 GHz in wireless networking?

• 2.4 GHz is always faster than 5 GHz.

• 2.4 GHz has a longer range and lower speeds, while 5 GHz has faster speeds and shorter range.

• 5 GHz has a longer range and lower speeds.

• 2.4 GHz and 5 GHz have the same range and speed.

What security protocols are commonly used in wireless networks?

• WEP, WPA, WPA2, WPA3

• IPSec, L2TP, PPTP

• FTP, SFTP, SCP

• SSL, TLS, HTTPS
