Study Notes
Phone and Tablet Connectivity
- Various wired and wireless options exist for connecting phones and tablets.
- Connectivity facilitates internet access, email, browsing, backups, identification, and system synchronization.
- USB (Universal Serial Bus) is a common wired connection type.
- USB types include Type-A, mini-B, micro-B, and USB-C.
- USB-C is a versatile connector for both data and video transfer (e.g., DisplayPort, HDMI, Thunderbolt).
- Apple devices often use Lightning connectors, which offer faster charging and are reversible.
- Numerous cables for different connector types (USB, mini-USB, micro-USB, Lightning) are necessary for technicians.
Older Connection Types
- Before USB, serial communication (e.g., DB-9/DE-9) was used for various functions.
- DB-9 is a 9-pin connector for RS232 signals.
- DB-9 connectors are still found on networking equipment (switches, routers).
- Conversion cables from USB to DB-9 are needed for older devices.
Wireless Connection Types
- NFC (Near Field Communication) allows data transfer between devices in close proximity.
- NFC is used for payments, data transfer, and electronic access.
- Bluetooth is a popular wireless method for connecting to headsets, earbuds, and car audio systems.
Wi-Fi Hotspots
- Mobile phones can be used as Wi-Fi hotspots.
- Users can share their mobile internet connection with other devices.
- Hotspot functionality is sometimes dependent on additional charges or phone support.
- This is a technique to enable devices with 802.11 capability to access internet where it is not directly available.
