1 raw format format for capturing maximum continuous-tone color information. It preserves all information when photograph was taken. psd files (photoshop default) layered photoshop continuous-tone (photograph) file format for photoshop editing only, saved in RGB. tiff files (tagged image file format) flattened uneditable photoshop continuous-tone file format for print application, saved in CMYK. pdf files (portable document format) portable format for and printing. It embeds all the necessary font and graphic files. eps files (encapsulated postscript) file format for finished Illustrator files and duotones for print application, saved in CMYK.
2 jpeg files (joint photographic experts group) continuous-tone file format for screen application, saved in RGB. gif files (graphic interchange format) file format for line art or vector images for screen application, saved in RGB. png files (portable network graphics) multiple levels of transparency file format for screen application, saved in RGB. Not too popular.
3 line art image drawn with lines, no shading. vectors image composed of paths, resolution independent. bitmaps or rasters image composed of pixels. Rasterizing converts vectors to bitmaps, resolution dependent. bit depth the number of available colors in a document. Bit depth refers to the amount of information stored within each pixel. 1-bit: Bitmap (Line Art) 16-bit: Color (usually for video) 8-bit: Grayscale/Index Color 24-bit: Color (usually for print) illustrator illustration and drawing, uses vectors. indesign page layout, uses vectors. photoshop photographic correction, uses pixels.
4 duotone two color image, two channels, two color job. continuous tone images (photographs) in which colors and shades of gray smoothly merge into the neighboring colors or shades, instead of producing distinct, sharply-outlined areas of color or shade. half tone images made from a series of dots that simulate the look of a continuous-tone image. A photograph reproduced in a newspaper or printed on a laserprinter. Because printers cannot print continuous-tones you must convert these images to halftones. Scanning converts a continuous-tone image (a photograph) into a halftone.
5 Byte there are 8 bits in 1 byte, and it is abbreviated as the letter B. One text character on a page is approximately one byte. Kilobyte Kilo means a thousand in Greek. There are approximately 1000 bytes in a kilobyte, which is abbreviated as KB. One typed out page is about 1 KB. Megabyte Mega means great in Greek. There are 1024 kilobytes in a megabyte, which is abbreviated as MB. A high-resolution photograph is approximately 2 to 3 MB. Gigabyte Giga comes from Latin meaning giant. There are 1024 Megabytes in a gigabyte, abbreviated GB. An hour of standard video is approximately 1 GB. One hour of high-definition video is closer to 4 GB. Terabyte Tera means monster in Greek. There are 1024 Gigabytes in a Terabyte, which is abbreviated TB. 1 TB is equal to 250,000 MP3 songs.
6 speed of processor is listed in hertz. Measures how quickly your computer can read and execute the instructions it receives. RAM (random access memory) the more ram the more space for programs to run off. Allows you to have many programs open at once. size of hard drive indicates how much data it can hold. operating system controls the user interface. It manages the mouse, monitor, keyboard, printer, etc... and controls how they work together. It tells your computer where to store and organize files. It is a platform on which software runs.
