This device connects all segments of a network in a star topology Ethernet network.
What is a hub?
This is the maximum number of characters an SSID can have.
What is 32?
This device connects multiple devices on a network and uses MAC addresses to forward data to the correct destination.

The group was responsible for developing the OSI Model
What is the ISO?
The purpose of NTP
What is making sure all the clocks on the same network are synchronized.
This accepts wireless clients through an analog wireless signal.
What is an access point?
This type of antenna sends and receives signals equally from all directions.
What is an omnidirectional antenna?
The term for a unique identifier assigned to a network interface for communication on the physical network segment.
What is a MAC address?
This address is used by devices on the same network to communicate without using a router.
What is a Private IP Address?
The layer that defines the electrical and physical specifications for devices
What is the Physical layer?
The port reserved for HTTP
What is port 80?
This device modulates an analog carrier signal to encode digital information and demodulates the signal to decode transmitted information.
What is a modem?
This replaced WEP due to cryptographic weaknesses.
What is WPA?
This model standardizes network communication into seven layers, including the Application and Transport layers.
What is the OSI Model?
A unique number that identifies a specific process or service on a networked device.
What is a Port Number?
The ______ layer provides the functional and procedural means to transfer data between network entities and to detect and possibly correct errors that may occur in the ______ layer.
data link/physical, network/transfer, physical/presentation, session/transport
What is the data link/physical layer?
A protocol that allows for secure tunneling where many different types of protocols can be used inside this tunnel
What is IPSec?
This network device operates on Layer 2 of the OSI model.
What is a switch?
This cellular technology assigns a unique code to every call or transmission and spreads the data across the spectrum.
What is CDMA?
The layer responsible for end-to-end communication and error checking in the OSI Model.
What is the Transport Layer?
The encryption protocol often used to secure communication over Wi-Fi networks.
What is WPA2?
The layer which provides transparent data transfer between end users
What is the Transport layer?
Adding information to a packet
What is encapsulation?
This can convert one type of cabling to another.
What is a media converter?
These are all standards for 5G technology.
What are OFDM, MIMO, and nm Waves?
A network topology where every device is connected to every other device directly.
What is Mesh topology?
The process of dividing a network into smaller, manageable segments to improve performance and security.
What is subnetting?
