Glossary of Terms for “Personal Electronics (Gadgets)”
Bluetooth — a wireless technology standard that allows devices like smartphones, headphones, and speakers to communicate and transfer data over short distances.
Wi-Fi — a technology that allows electronic devices to connect to the internet or communicate wirelessly within a specific range. Wi-Fi is typically faster and has a broader range than Bluetooth.
NFC (Near Field Communication) — a wireless communication technology that enables devices to exchange data over very short distances, often used for contactless payments (e.g., mobile payment apps).
Wearable — any electronic device designed to be worn on the body, such as smartwatches, fitness trackers, and smart glasses.
AMOLED (Active Matrix Organic Light Emitting Diode) — a type of display technology used in smartphones, smartwatches, and other gadgets. AMOLED screens are known for their vibrant colors, deep blacks, and energy efficiency.
Battery Capacity (mAh) — the amount of energy a battery can store, measured in milliamp hours (mAh). Higher capacity generally means longer battery life for devices like smartphones and wireless earbuds.
Fast Charging — a feature that allows devices to recharge their batteries at a faster rate than standard chargers, reducing the time needed to fully charge a gadget.
IP Rating (Ingress Protection) — a rating system that indicates a device’s resistance to dust and water. For example, IP68-rated devices are dust-tight and can be submerged in water for a specified time without damage.
5G — the fifth-generation mobile network technology that offers faster internet speeds and lower latency compared to previous generations (like 4G), improving the performance of smartphones and other connected devices.
Biometric Authentication — security features that use personal physical characteristics, such as fingerprints, facial recognition, or iris scans, to unlock a device or verify identity.
Touchscreen — a display that allows users to interact with the device by touching the screen with their fingers. It is commonly found in smartphones, tablets, and smartwatches.
Wireless Charging — a feature that allows electronic devices to charge without being plugged in, using electromagnetic fields to transfer power from a charging pad to the device.
USB-C — a universal port and connector type used for charging and data transfer on many modern electronic devices, known for its speed and versatility.
Refresh Rate (Hz) — the number of times per second that a screen refreshes its image, measured in Hertz (Hz). Higher refresh rates (e.g., 90Hz or 120Hz) result in smoother scrolling and more fluid video playback.
TWS (True Wireless Stereo) — a type of wireless audio technology used in earbuds and headphones that allows two separate earbuds to connect to a device without any wires, offering stereo sound.
Smart Assistant — a digital assistant that uses artificial intelligence (AI) to respond to voice commands and help with tasks like setting reminders, sending messages, or controlling smart home devices (e.g., Siri, Google Assistant, Alexa).
Bezel-less Display — a type of screen design that minimizes the borders around the display, providing a larger viewing area on devices like smartphones and tablets.
OLED Display — a display technology similar to AMOLED, where each pixel emits its own light, providing superior color accuracy and contrast, especially in dark scenes.
Gorilla Glass — a type of durable, scratch-resistant glass used to protect the screens of smartphones, tablets, and other gadgets from everyday wear and tear.
Processor (CPU) — the central processing unit of a device, responsible for executing instructions and performing tasks. More powerful processors lead to faster performance and better multitasking in gadgets.
RAM (Random Access Memory) — a type of memory that a device uses to store temporary data while performing tasks. More RAM allows a gadget to run multiple apps and processes smoothly at the same time.
Storage Capacity (GB, TB) — the amount of data a device can store, typically measured in gigabytes (GB) or terabytes (TB). This includes apps, photos, videos, and other files.
VR (Virtual Reality) — a technology that creates an immersive, computer-generated environment that users can interact with, typically through a headset or goggles.
AI (Artificial Intelligence) — software technology that enables devices to perform tasks typically requiring human intelligence, such as voice recognition, camera enhancements, and personalized recommendations.
Gyroscope — a sensor in gadgets that detects rotational movement, allowing for more precise motion control in applications like gaming or fitness tracking.
Haptic Feedback — a tactile response technology that uses vibrations or small motions to simulate touch interaction, enhancing the user experience in devices like smartphones and game controllers.
