What is device?
A device is any piece of hardware that performs a specific function or set of functions, like a phone, computer, printer, or smartwatch. It’s a physical object you can touch, and it usually contains electronic components that process data or interact with the world.
Let's break it down
- Hardware: The tangible parts (screen, buttons, chips).
- Software: The instructions that tell the hardware what to do.
- Input: How you give the device information (typing, tapping, voice).
- Output: How the device shows results (display, sound, vibration).
- Power: What makes it run (battery or plug).
Why does it matter?
Devices are the tools we use to communicate, work, learn, and entertain ourselves. Understanding them helps you choose the right tool for a task, troubleshoot problems, and stay safe online.
Where is it used?
- Home: TVs, smart speakers, thermostats.
- Work: Laptops, monitors, printers.
- Travel: Smartphones, GPS units, portable chargers.
- Industry: Sensors, robots, control panels.
- Healthcare: Wearable monitors, diagnostic machines.
