7.Tablet Computers
Purpose: Portable devices with touchscreens for media consumption, reading, and light productivity.
Examples: iPads, Android tablets.
Characteristics: Larger than smartphones, typically more portable than laptops, and often include touchscreen interfaces.
8.Wearable Computers
Purpose : Small, portable devices worn on the body to provide various functions such as health tracking and communication.
Examples: Smartwatches, fitness trackers.
Characteristics: Compact, often connected to other devices like smartphones.
9.Gaming Consoles
Purpose: Designed primarily for playing video games but can often perform other tasks like streaming media.
Examples: PlayStation, Xbox, Nintendo Switch.
Characteristics: Optimized for graphics-intensive tasks, specialized controllers.
10.Quantum Computers
Purpose: Use quantum mechanics to solve complex problems that are currently intractable for classical computers.
Examples: Research in cryptography, drug discovery, and artificial intelligence.
Characteristics: Still in experimental stages, potentially thousands of times faster than classical computers for specific tasks.
Example systems: IBM Q, Google’s Sycamore.
