Network Devices
This device operates at Layer 2 and forwards frames based on MAC addresses.
What is a switch?
This twisted-pair cable type supports up to 100 Mbps Ethernet.
What is Cat5?
In this topology, each device connects to a central hub.
What is star topology?
A network confined to a single building or small area.
What is a LAN (Local Area Network)? What is port 443?
This 802.11 standard introduced MIMO and operates at both 2.4 and 5 GHz.
What is 802.11n?
This device connects multiple network segments and can operate at multiple OSI layers. This device connects multiple network segments and can operate at multiple OSI layers.
What is a router?
This fiber connector type resembles a push-pull mechanism and is commonly paired.
What is LC (Lucent Connector)?
This topology connects each node directly to every other node.
What is mesh topology?
A private network connecting campuses or large buildings.
What is a CAN (Campus Area Network)?
The maximum theoretical speed of 802.11ac.
What is 1.3 Gbps (or higher with Wave 2)?
This device regenerates and amplifies signals to extend cable length.
What is a repeater?
This cable type uses BNC connectors and was once popular for legacy Ethernet.
What is coaxial cable?
A failure in a single cable can bring down the whole network in this topology.
What is bus topology?
This personal-scale network typically connects devices like phones and headphones.
What is a PAN (Personal Area Network)?
WPA3 improves this aspect of wireless security over WPA2.
What is encryption and forward secrecy?
A device that combines multiple network functions, often used in SOHO setups.
What is a multi-function device or gateway?
The maximum cable length for a Cat6 Ethernet run without a repeater.
What is 100 meters?
A token-passing protocol is often associated with this physical topology.
What is ring topology?
This network type supports data center-level storage over fiber.
What is a SAN (Storage Area Network)? What is SSH (Secure Shell)?
This type of wireless authentication uses RADIUS.
What is enterprise mode (802.1X)?
Unlike switches, this older device floods all ports and operates strictly at Layer 1.
What is a hub?
This twisted-pair cable standard can support 10 Gbps over short distances and is shielded.
What is Cat6a?
This hybrid topology blends star and bus topologies for scalability and fault tolerance.
What is tree topology?
A type of network used to connect geographically dispersed sites, often via leased lines.
What is a WAN (Wide Area Network)?
The 6 GHz band is introduced in this Wi-Fi generation.
What is Wi-Fi 6E?
