Network media devices Flashcards
Which network component is responsible for managing the wireless connection?
Access Point
Access Points connect wireless devices to a wired network.
Which network component manages the flow of data between buildings connected by underground fiber-optic cables?
Router
Routers direct data packets between different networks.
What function does a firewall serve in a network?
Traffic filtration in accordance with rule sets
Firewalls help protect networks by controlling incoming and outgoing traffic.
For Wireless LAN connectivity, which device is typically used?
Wireless Access Point (WAP)
WAPs provide connectivity for wireless devices in a local area network.
A router’s primary purpose in a network is?
To route data packets between multiple networks
Routers determine the best path for data transmission.
Which hardware device forwards a signal out all connected ports without examining the frame or packet contents?
Hub
Hubs are basic devices that do not filter data traffic.
A switch forwards data only to the port that is connected to the destination device. It knows which port to forward it to based on which value?
MAC Address
Switches operate at Layer 2 of the OSI model, using MAC addresses for data forwarding.
Which type of router would be most appropriate for managing internal network connections in an office?
Core Router
Core routers handle data traffic within a network.
Which device is responsible for amplifying or regenerating signals to extend a network?
Repeater
Repeaters strengthen weak signals to maintain network integrity.
Which network device connects internal networks to external networks like the internet?
Edge Router
Edge routers serve as gateways between internal networks and external networks.
What is the primary function of a modem in a network?
Sending and receiving data; allows computers to transport digital information over analog lines such as phone or cable lines
Modems modulate and demodulate signals for data transmission.
Which network device is responsible for forwarding data packets to all connected ports without filtering?
Hub
Hubs do not distinguish between data packets; they broadcast to all ports.
What network device joins two separate network segments together?
Bridge
Bridges connect and filter traffic between different network segments.
Which device manages wireless connections by providing connectivity between wireless devices and a wired network?
Access Point
Access Points facilitate communication between wired and wireless networks.
Which network component is used to extend the coverage of a wireless network?
Wireless Range Extender (WRE)
WREs amplify wireless signals to cover larger areas.
Which router is responsible for routing data within a large network such as the internet backbone?
Core Router
Core routers are critical for managing large-scale data traffic.
What device connects individual subscribers to the wider telecom infrastructure?
Subscriber Edge Router
Subscriber Edge Routers enable customer access to broader networks.
Which network device functions at both Layer 3 and Layer 4 and serves as a primary security device?
Firewall
Firewalls can monitor and control traffic at multiple layers of the OSI model.
Which device is used by ISPs to connect to other ISPs and is considered the backbone of the internet?
Inter-Provider Border Router
These routers facilitate data exchange between different networks.
Which network device connects devices within a specific network and allows efficient communication using MAC addresses?
Switch
Switches improve network efficiency by directing data to specific devices.
What determines the best path for data transmission between multiple networks?
Router
Routers analyze network conditions to select optimal routes for data packets.
