2. Compact Keyboards (e.g., 87-key, 88-key, or 89-key):
· These keyboards have fewer keys, omitting the numeric keypad, and are usually more compact for portability.
3. Laptop Keyboards:
· Laptops typically have between 75 and 85 keys, depending on the model and whether they have a numeric keypad.
4. Tenkeyless Keyboards:
· These are similar to the full-size keyboard but do not have the numeric keypad, so they usually have about 87 keys.
The key count can vary by layout and region, but the most common "full-size" keyboard has 104 keys.
