2. About WiFi
Wi-Fi is a trademark of the Wi-Fi Alliance,
•
founded in 1999 as WECA. The organisation
comprises more than 300 companies, whose
products are certified by the Wi-Fi Alliance,
based on the IEEE 802.11 standards. This
certification warrants interoperability between
different wireless devices.

3. About PVR
Short for personal video recorder, a generic term
•
for a device that is similar to a VCR but records
television data in digital format as opposed to the
VCR s analog format. VCRs utilize analog
tapes to record and play programs broadcast over
television, but PVRs encode video data in
MPEG-1 or MPEG-2 formats and store the data
in a hard drive. PVRs have all of the same
functionality of VCRs (recording, playback, fast
forwarding, rewinding, pausing) plus the ability
to instantly jump to any part of the program
without having to rewind or fast forward the data
stream.

4. About Digital audio player
A digital audio player, more commonly referred
•
to as an MP3 player, is a consumer electronics
device that stores, organizes and plays audio files.
Some DAPs are also referred to as portable media
players as they have image-viewing and/or
video-playing support. MP3 players are now
regularly built into mobile phones, making them
the most common form of digital audio player.

5. About USB
In information technology, Universal Serial Bus
•
(USB) is a serial bus standard to interface devices
to a host computer. USB was designed to allow
many peripherals to be connected using a single
standardized interface socket and to improve the
Plug and play capabilities by allowing hot
swapping, that is, by allowing devices to be
connected and disconnected without rebooting
the computer or turning off the device. Other
convenient features include providing power to
low-consumption devices without the need for an
external power supply and allowing many devices
to be used without requiring manufacturer
specific, individual device drivers to be installed.
