Compression
Data compression is a set of rules for packaging data into a smaller slot. While allowing the original data to be seen again. Compression is a two-way process: a compression algorithm can be used to make a data package not as large, but can also be run the opposite way to decompress the package into its original form. Data compression is useful in computing because it helps save a lot of disk space, or to reduce the bandwidth used when sending data via the internet.
Image Capture
Image capture is the process of getting a digital image from a vision sensor, such as a camera. Usually this entails a hardware interface known as a frame grabber, which captures single frames of a video and converts the analogue values to a digital, and feeds the result into the computer memory.
Optimising
Optimising in imagery is where you reduce the picture file size too as small as possible whilst also making sure it maintains the graphics it needs to serve a certain purpose. Through this method it ultimately reduces the download time and the size making it easier to display on the browser. It also reduces the bandwidth.
Storage of image assets
A storage of image assets is where you would give things name so that you do not get mixed up. You would save the documents as a PSD so that they remain open and able to edit if you are working with other people and send them the files. You would name them something obvious relating to what they are such as if it was a bin you would call it "bin" then save and send it using the PSD file. You also need to make sure that your computer is up too date enough so that you can edit or create the game as well as making sure you have enough storage on your memory stick or hard drive since all of the files would take up a lot of room.
