SD/Media card slot
SD (Secure Digital) cards are a type of memory card used for portable devices, such as mobile phones, digital cameras, GPS navigation devices and tablet computers. SD cars are used for storing digital media (e.g. audio, video and picture files).
Meanwhile, a media card is a small cardlike information storage device that holds data in flash memory.
An optical fiber cable is a cable that contains one or more optical fibers. The optical fiber elements are individually coated with plastic layers and contained in a protective tube suitable for the environment where the cable will be arranged. They are used to transfer digital data between digital components using bursts of light that is carried over glass or plastic fibers. Optical fibers are able to transmit large amounts of information at the speed of light.
HDMI (High-Definition Multimedia Interface) is a digital way of transferring uncompressed audio and digital data from a HDMI-compliant device to a compatible digital audio device, computer, video projector or digital television. It is also able to send and receive signals for compatible device control and it has a built in content protection.
Bluetooth is a standard for the short-range wireless interconnection of cellular phones, computers and other electronic devices.
Bluetooth is a proprietary open wireless technology standard for exchanging data over short distances (using short-wavelength radio transmissions in the ISM band from 2400–2480 MHz) from fixed and mobile devices, creating personal area networks (PANs) with high levels of security. Created by telecoms vendor Ericsson in 1994, it was originally conceived as a wireless alternative to RS-232 data cables. It can connect several devices, overcoming problems of synchronization.
