2.2 Networking Hardware Flashcards
What is the primary function of a network switch?
To connect devices in a LAN and manage data traffic between them.
What is the difference between a hub and a switch?
A hub broadcasts data to all ports, while a switch sends data only to the intended device.
What is the purpose of a router?
To connect multiple networks and direct data packets between them.
What is the function of a modem?
To convert digital signals to analog for transmission over telephone lines and vice versa.
What is the role of a wireless access point (WAP)?
To extend a wired network and allow wireless devices to connect.
What is the difference between a managed and unmanaged switch?
Managed switches support configuration, monitoring, and VLANs, while unmanaged switches do not.
What is a firewall used for?
To monitor and control incoming and outgoing network traffic based on security rules.
What is a network bridge?
A device that connects two network segments and reduces traffic by filtering data.
What is a repeater in networking?
A device that amplifies signals to extend the distance of a network connection.
What is the purpose of a patch panel?
To organize and connect network cables in a central location.
What is a PoE switch?
A switch that provides Power over Ethernet to devices like IP cameras and WAPs.
What is the role of a gateway in a network?
To connect two different networks and translate communication protocols.
What is a NIC?
Network Interface Card, a hardware component that connects a device to a network.
What is the purpose of a media converter?
To convert network signals between different media types, like fiber and copper.
What is a load balancer?
A device that distributes network traffic across multiple servers to improve performance.
What is the function of a proxy server?
To act as an intermediary between clients and servers, enhancing security and performance.
What is a Layer 3 switch?
A switch with routing capabilities, allowing it to direct traffic between VLANs.
What is the difference between single-mode and multimode fiber?
Single-mode fiber is used for long-distance communication, while multimode fiber is for shorter distances.
What is the purpose of a wireless range extender?
To boost and extend the coverage of a wireless network.
What is the function of a NAS device?
Network-Attached Storage provides file storage and sharing over a network.
What is a print server?
A device or software that manages print jobs on a network.
What is the purpose of a VoIP gateway?
To convert voice data between traditional phone lines and VoIP networks.
What is a CSU/DSU?
Channel Service Unit/Data Service Unit, a device that connects a router to a digital circuit.
What is the function of a demarcation point?
The point where the service provider’s network ends and the customer’s network begins.
What is a patch cable?
A short cable used to connect devices to a switch, router, or patch panel.
What is an SFP module?
Small Form-factor Pluggable, a transceiver used for network connections like fiber or copper.
What is the role of a content filter?
To block or restrict access to specific websites or content based on policies.
What is the difference between a wired and wireless router?
A wired router connects devices using Ethernet cables, while a wireless router also provides Wi-Fi connectivity.
What is the purpose of a KVM switch?
To allow control of multiple computers using a single keyboard, video display, and mouse.
What is the difference between a firewall and an IDS?
A firewall blocks or allows traffic, while an Intrusion Detection System monitors for malicious activity.
What is a load balancer’s primary purpose?
To distribute network or application traffic across multiple servers to ensure reliability.
What is the difference between a modem and a router?
A modem connects to the internet, while a router distributes that connection to devices in a network.
What is an unmanaged switch?
A plug-and-play device that does not allow configuration or management.
What is the purpose of an access point controller?
To manage and configure multiple wireless access points in a network.
What is a power injector in PoE?
A device that adds power to an Ethernet cable for devices that require Power over Ethernet.
What is a transceiver?
A device that transmits and receives signals in networking hardware.
What is the purpose of a media access unit (MAU)?
To provide connectivity in Token Ring networks.
What is the difference between a hardware and software firewall?
A hardware firewall is a standalone device, while a software firewall runs on a computer or server.
What is a network appliance?
A dedicated hardware device designed for specific network functions, like firewalls or proxies.
What is the purpose of a multilayer switch?
To operate at multiple OSI layers, providing both switching and routing functions.
What is an intrusion prevention system (IPS)?
A system that actively blocks detected threats in a network.
What is a network tap?
A device that provides a way to monitor network traffic for analysis or troubleshooting.
What is a VPN concentrator?
A device that manages multiple VPN connections for secure remote access.
What is the purpose of a wireless bridge?
To connect two separate wired networks using a wireless link.
What is the function of a DSL modem?
To connect a network to the internet using a Digital Subscriber Line connection.
What is the purpose of a network analyzer?
To capture and analyze network traffic for troubleshooting or security purposes.
What is an edge device in networking?
A device at the boundary of a network that connects internal devices to external networks.
What is the difference between a core and distribution switch?
A core switch handles high-speed traffic in the backbone, while a distribution switch connects access switches to the core.
What is the purpose of a network hub?
To connect multiple devices in a network, but it broadcasts data to all devices.
What is a virtual switch?
A software-based switch that connects virtual machines in a virtualized environment.
What is a UTM appliance?
Unified Threat Management, a device that combines firewall, antivirus, and intrusion prevention functions.
