Bluetooth: A wireless technology for exchanging data over short distances from fixed and mobile devices.
Chassis: The laptop's casing, which can affect weight and durability. Common materials include plastic, aluminum, and carbon fiber.
Cloud Storage: Storing data on remote servers accessed from the internet rather than on the laptop's hard drive.
CPU (Central Processing Unit): Often referred to as the computer's brain, it processes instructions from software and hardware.
Data Encryption: The process of converting data into another form, or code, to prevent unauthorized access.
Display Panel Types:
IPS (In-Plane Switching): Offers good viewing angles and color reproduction.
TN (Twisted Nematic): Common in budget laptops, it has faster response times but poorer viewing angles.
OLED (Organic Light Emitting Diodes): High contrast ratio, true blacks, and vibrant colors, often found in high-end models.
DisplayPort: A digital display interface primarily connects a video source to a display device.
Docking Station: A device that allows a laptop to connect to multiple devices simultaneously, essentially turning it into a desktop setup.
DLNA (Digital Living Network Alliance): A standard to share media over a network between computers, TVs, and other devices.
Drivers: Software that allows the operating system to communicate with hardware devices.
Ergonomics: The study of people's efficiency in their working environment. With laptops, it often refers to keyboard, touchpad, and screen design for user comfort.
Ethernet Port: A port for connecting to wired networks, offering more stable internet connections than Wi-Fi.
Fan: An active cooling component that moves air over heat sinks to help regulate the temperature of internal components.
Firewall: A network security system that monitors and controls incoming and outgoing network traffic based on predetermined security rules.
Form Factor: The size, shape, and style of the laptop. Examples include traditional clamshell, 2-in-1, and convertible designs.
Frame Rate: The frequency at which consecutive images (frames) appear on a display.
GPU (Graphics Processing Unit): Handles rendering of images, videos, and animations. Essential for gaming and graphic-intensive tasks.
Hard Drive: The primary storage device it stores all data, including the operating system, applications, and files. It comes in two types:
HDD (Hard Disk Drive): Older, mechanical storage device.
SSD (Solid State Drive): Faster, more reliable, and uses flash memory.
HDR (High Dynamic Range): A technology for displaying a wider range of colors and contrasts.
Heat Sink: A passive cooling component used to dissipate heat from critical components like the CPU and GPU.
HDMI (High-Definition Multimedia Interface): A port for transmitting high-definition video and audio to an external display or TV.
Keyboard: The set of keys used to input data. Can be backlit or have varying key travel and actuation points.
Liquid Cooling: A cooling method that uses a liquid coolant to transfer heat away from components, more efficient than air cooling.
Machine Learning/Artificial Intelligence Capabilities: Some modern laptops have specialized hardware for AI and machine learning tasks.
M.2 Slot: A slot on the motherboard for an M.2 form factor SSD, which is smaller and faster than traditional SATA SSDs.
Miracast: A standard for wireless connections from devices to displays, allows for screen mirroring.
Motherboard: The main circuit board that connects all components of the laptop, including CPU, GPU, RAM, and hard drives.
NFC (Near Field Communication): Allows two devices to communicate when they are close together, used for wireless payments and quick pairing.
Operating System (OS): The software that manages all other software and hardware. Common examples include Windows, macOS, and Linux.
Overclocking: The process of increasing the clock speed of a CPU or GPU beyond the manufacturer's specifications for improved performance.
Pixel: The smallest unit of a digital image or graphic that can be displayed and edited on a digital display.
Ports: Connectors for external devices. Common types include USB, HDMI, and Thunderbolt.
Power Adapter: The external device that provides power to the laptop and charges the battery.
RAM (Random Access Memory): Short-term memory where data is stored for quick access. Higher RAM means better multitasking and performance.
Refresh Rate: Measured in Hertz (Hz), it's the number of times the screen refreshes its image per second. Higher rates offer smoother motion.
Refresh Rate vs. Frame Rate:
Refresh Rate: The number of times the display updates with new images each second.
Frame Rate: The frequency at which consecutive images (frames) appear on a display.
Resolution: The number of pixels on the screen. Common resolutions include HD (1280x720), Full HD (1920x1080), and 4K (3840x2160).
SD Card Reader: A slot that allows you to read from and write to SD cards, commonly used in cameras.
Screen Coating:
Matte: Reduces glare and reflections, better for use in well-lit environments.
Glossy: Offers more vibrant colors and contrast but is prone to glare.
Single Sign-On (SSO): A property of access control that allows a user to log in once and gain access to multiple systems without being prompted to log in again.
SSD (Solid State Drive): A modern type of storage device that uses flash memory. Faster and more reliable than traditional HDDs.
Thunderbolt: A hardware interface developed by Intel that provides high-speed connections for data and video.
Touchpad: A touch-sensitive pad used to control the cursor.
Touchscreen: A display that also acts as an input device, responding to touch gestures.
TrackPoint: A pointing stick mainly found on Lenovo ThinkPads, used as a mouse.
USB-C: A type of USB connector that is reversible and supports faster data transfer and power delivery.
