2.5G/3G
For popular types of mobile phone, 'G' refers to 'generation'. 2.5G phones offer voice and low-speed data. Whereas 3G models support broadband-like data transfer suitable for video calls and fast internet browsing. EDGE falls somewhere in between and HSDPA (Super 3G) is a faster extension of 3G.
24p
A video format that operates at 24 progressive scan frames per second (fps) - the speed at which feature films are shot. Offers smooth video motion.
720p/1080i/1080p
Types of HD video. The number represents the lines of vertical resolution and the 'i' or 'p' denotes interlaced or progressive scan. 1080p - or Full HD - is the crispest form of High Definition.
802.11x
The technical name for Wi-Fi networks ('x' is replaced with various other letters). Most current wireless networks are 802.11g (54Mbps) but the new standard will soon be 802.11n, which supports greater speeds and acts over greater distances. Almost all 802.11x devices work well together.
A2DP (Advanced Audio Distribution Profile)
Software that allows audio streaming over Bluetooth. Devices with A2DP support wireless headphones and can send audio to Bluetooth speakers. Often found in AVRCP, which gives you remote control of the music on a device.
Now to test if you paid attention... decipher what the caption says.
LG KE970 ShineThe Shine is available in both 2.5G and 3G versions. Not that it matters - you'll buy it for its looks and all-metal construction.
And that's all for today's class. Did I catch you dozing off?
