100
This standard connector for wired LANs contains eight pins arranged in four twisted pairs.
What is an Ethernet connector (or RJ45)?
100
This set of standards, also known as 802.11X, is used to connect devices over a wireless LAN.
What is Wi-Fi?
100
These devices are automatically recognized and configured by an Operating System without needing manual driver installation.
What are Plug-and-Play (PnP) devices?
100
This modern, reversible connector can handle data, video, and power, and is used by both Thunderbolt and modern phones.
What is USB-C
100
This digital interface is the most common for consumer electronics like TVs and laptops because it carries both audio and video.
What is High-Definition Media Interface (HDMI)?
200
These interfaces are immune to electromagnetic interference (EMI), which protects against eavesdropping and improves security.
What are Small Form-Factor Pluggable (SFP) connectors?
200
This short-range technology is commonly used for contactless payments and quick data exchanges between very close devices.
What is Near-Field Communication (NFC)?
200
This type of peripheral connects to a user’s network rather than directly to their computer.
What is an IP-based peripheral?
200
This proprietary Apple connector is used for charging and data transfer on iPhones and iPads.
What is Lightning?
200
This legacy analog video standard uses a bulky connector and is susceptible to signal degradation.
What is Video Graphics Array (VGA)?
300
This tool is used to attach connectors to the end of network cables to allow for custom lengths.
What is a crimper?
300
Unlike Bluetooth, this broader wireless category includes Wi-Fi and NFC and uses radio waves to communicate.
What is Radio Frequency (RF)?
300
This device provides temporary backup power to a computer if the main power goes out.
What is an Uninterruptable Power Supply (UPS)?
300
This high-speed interface supports data transfer rates up to 40 Gbps and uses the USB-C connector.
What is Thunderbolt?
300
This process duplicates the entire screen of a source device onto a target device.
What is mirroring?
400
These are the two wiring standards used for Ethernet connectors where the color order of the pairs differs.
What are EIA/TIA-568A and EIA/TIA-568B?
400
This technology is specifically designed for battery-operated devices and relatively short distances but has slower transfer rates than most wired options.
What is Bluetooth?
400
To access a modern peripheral's web-based interface for setup, a user must first obtain this specific address.
What is an IP Address?
400
This type of USB port is most commonly found on the back of printers and scanners.
What is USB-B?
400
Unlike mirroring, this process sends only specific content to a display, allowing the source device to be used for other tasks.
What is casting?
500
This device is used to check the functionality and integrity of cables, identifying issues like wiring faults or short circuits.
What is a cable tester
500
This is a primary security concern for Wi-Fi because it is susceptible to physical obstructions and this specific type of disruption from other devices.
What is interference?
500
This specific maintenance step may be required for printers or scanners to ensure they operate with optimal accuracy.
What is calibration?
500
This 3.5mm interface is the standard connection for these three types of audio peripherals.
What are headphones, microphones, and speakers?
500
This digital interface supports high-end performance, such as 8K resolution and 240 Hz refresh rates.
What is DisplayPort?
