DATA
Means groups of information that represent the quality or quantitative attributes of a variable. Data is typically the results of measure meets and can be the basis oaf diagrams images or observation of a set of images.
A bit - is the basic unit of information in computer and telecommunications.
Byte is a unit of digital information in computing and telecommunications.
1024 Bytes - 1KB (kilobyte)
1024 Kilobytes - 1MB (megabytes)
1024 Megabytes - 1GB (gigabytes)
A BIT IS A PART OF A BYTE (i took a little bit from my bite)
Data compression -
Also called source coding is the process of encoding information using few than an unencoded representation would use. e.g. Zipping files.
Helps save space on hard drives. Downside - compressed data must be decompressed before anything can be done to it.
AUDIO DATA
Sampling rate - the number of samples per second measured during the recording process + to digitize a certain so
und. Measured in Hertz. Common sampling rate for stereo audio is 44,100 per second.The higher your sampling rates, the better your results.
Sample Size - The size of the audio being streamed e.g. Imb.
Digitizing - conversion of analog signals which are continuous electri
cal signals to digital signals which are non continuous to converting it to a stream of numbers to get audio onto a computer. Nearly all recorded music has been digitized.
Bit Rate - amount of information that is transferred per second (bits per second)
The higher bits taken per second the smoother the sound.

Video Data
Refers to electronically capturing, recording, precessing storing, transmitting and displaying a sequence of still images that recorded many times a second to produce scenes in motion.
It is in a format that can be presented on television (or on any video supporting device for that matter)
A video mainly consists of:
- Still images (image frames)
- Audio
Sample rate is the number of measurements taken every second.
in terms of video + audio, the more accurate "digitized" sound or video, the higher the sampling rate and thereby more data measurements to be collected.
Measured by frequency (Hz).
Sample size refers to the capacity of a video data.
It is representation of units to be sampled that holds the statistical information of video data.
Frame rate - the rate at which an imaging device produces unique consecutive images called frames.
In short, frame rate are the number of frames which are shown in a second.
Video data consists of the amin componsesnts of framwork - images being recoreded into still frames and the recording of audio through a microphone in the camer. Video data is a representation of images that move or change. This also includes the various forms of animation.

Frame rate - the rate at which an imaging device produces unique consecutive images called frames.
In short, frame rate are the number of frames which are shown in a second.
- i stands for interlaced fields, so 50i = 25 frames. (does half a television refresh each turn)
- p stands for non interlaced fields so 52p = 50 frames. (does whole television each time, in half the time)
Video data consists of the amin componsesnts of framwork - images being recoreded into still frames and the recording of audio through a microphone in the camer. Video data is a representation of images that move or change. This also includes the various forms of animation.
