Final answer:
The main types of keyboards are standard, ergonomic, and gaming keyboards. The main types of touch screens are resistive, capacitive, and surface acoustic wave touch screens.
Step-by-step explanation:
The main types of keyboards are:
- Standard keyboards: These are the most common type of keyboards that include the QWERTY layout and are used for typing on desktop computers and laptops.
- Ergonomic keyboards: These keyboards are designed to provide a more comfortable typing experience by incorporating a split or curved layout that aligns with the natural position of the hands.
- Gaming keyboards: These keyboards are specifically designed for gaming enthusiasts and often feature additional programmable keys, backlighting, and advanced functions.
The main types of touch screens are:
- Resistive touch screens: These screens work by detecting pressure applied to the screen, typically using a stylus or finger. They are often found in ATMs and older mobile phones.
- Capacitive touch screens: These screens work by detecting changes in electrical charge when a conductive object, like a finger, comes into contact with the screen. They are commonly used in smartphones and tablets.
- Surface acoustic wave touch screens: These screens use sound waves to detect touch. They are known for their high clarity and durability, and are often used in public information kiosks and industrial applications.
