Hardware
A web camera, also known as a webcam, is a digital camera that connects to a computer and can transmit images or video over the internet.
- Function: Webcams capture still images or motion video, and can stream live video to a website, computer network, or other devices.
- Connectivity: They typically connect via USB, but can also be built into laptops or other devices.
- Uses: Common uses include video conferencing, online streaming, surveillance, and capturing images/videos for personal use.

The terms "AC" and "non-AC" typically refer to air-conditioned and non-air-conditioned spaces or vehicles.
AC (Air Conditioned):
- Indicates that a space or vehicle is equipped with an air conditioning system.
- Air conditioning cools the air, reducing temperature and often humidity.
- Examples include AC rooms, AC buses, AC trains, and AC cars.
Non-AC (Non-Air Conditioned):
- Indicates that a space or vehicle does not have an air conditioning system.
- Relies on natural ventilation (windows, fans) for cooling.
- Examples include non-AC rooms, non-AC buses, and non-AC trains.

The physical components of a computer are collectively known as hardware.
This encompasses all the tangible parts you can physically touch, such as:
-
Central Processing Unit (CPU): Often referred to as the "brain" of the computer, responsible for executing instructions. Source
-
Random Access Memory (RAM): Used for short-term data storage that the CPU accesses quickly. Source
-
Hard Disk Drive (HDD) or Solid State Drive (SSD): Used for long-term data storage. Source
-
Motherboard: The main circuit board that connects all the components. Source
-
Graphics Card (GPU): Processes and outputs images to the display. Source
-
Power Supply Unit (PSU): Provides power to all the components. Source
-
Input Devices: Devices used to input data into the computer (e.g., keyboard, mouse). Source
-
Output Devices: Devices used to output data from the computer (e.g., monitor, printer). Source
