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.
