Name Description
802.11n: 802.11n is a wireless or Wi Fi standard that was introduced in 2007. It supports longer range and high wireless transfer rates compared to its predecessors 802.11802.11. supports Multiple In and Multiple Out (MIMO) data transfers, which transmits multiple streams of data at once. This doubles the range of a wireless device.

802.11n also supports data transfer speeds of over 100Mbps, compared to the older versions which was up to 54 Mbps.
720p: 720p represents 1,280 pixels displayed across the screen horizontally and 720 pixels down the screen vertically. This arrangement yields 720 horizontal lines (pixel rows) on the screen, which are, in turn, displayed progressively, or each line displayed following another. This means that all 720 pixel rows are displayed at all times. Although 720p is high-definition, it takes up less bandwidth than 1080i or 1080p.
4k: 4K refers to one of two high definition resolutions: 3840 x 2160 pixels or 4096 x 2160 pixels. 4K is four times the pixel resolution, or twice the line resolution (2160p), of 1080p (1920 x 1080 pixels) that is one of main current consumer high definition resolution standards. The other high definition resolutions currently is use are 720p, 1080i or 1080p. 4K is now officially designated for consumer products as Ultra HD or UHD, but is also referred to at times, such as in professional or commercial settings as Ultra High Definition, 4K x 2K, or Quad High Definition.
480p: 480p represents 480 lines of resolution scanned progressively. 480p is similar to the same resolution of standard broadcast TV (and is referred to as SDTV or Standard Definition Television), but the image is scanned progressively, rather than in alternate fields.
480i: 480i represents 480 lines of resolution scanned alternately - with all odd lines scanned first, then all even lines. 480i is also commonly referred to as standard video resolution.
3.5mm Plug/Jack: Also referred to as a 1/8 inch, auxillary input, mini stereo, and mini phono. These are commonly found on portable devices like newer smartphones, tablets, laptops and computer sound cards. They are used to transmit audio.
16x9 6x9 represents a screen aspect ratio of 1.78 units of horizontal width to 1 unit of vertical height, which is usually expressed in terms of 16 units x 9 units. 16x9 is the standard aspect ratio for originally produced HDTV content, thus all TVs now sold have this aspect ratio. TV programming or video content transmitted or fed to a TV that is not in the 16x9 aspect ratio will appear on a 16x9 aspect ratio screen with black bars on the top and bottom of the image or black bars on either side of the image.
1080p 1080p represents 1,920 pixels displayed across a screen horizontally and 1,080 pixels down a screen vertically. However, unlike 1080i all pixel rows or lines are displayed progressively, providing the most detailed high definition video image that is currently available to consumers.
1080i 1080i represents 1,920 pixels displayed across a screen horizontally and 1,080 pixels down a screen vertically. This arrangement yields 1,080 horizontal lines (pixel rows), which are, in turn, displayed alternately. In other words, all the odd lines are displayed, followed by all the even lines. This means that only 1/2 the resolution (540 lines or pixel rows) is displayed on the screen at any given time - in other words, only 540 pixel rows are displayed at any given time.
