. Internaltional Morse code
. For comunication
. Usede in telegraph, Light house
. COmination of DOts and Bars
. Used in navy.
. Printers
. O/p device
. Laser:
. bulk amount of print
. 15-100 pages/ min
. Use powder >> heat >> Prints
. Maintaince is easy
. not good for clolor images
. Inkjet:
. most useful for color prints, 16 pages/min
. maintance is heigt compared to laser
. uses ink
. Thermal:
. slow
. used for Barcode labels
. prints will not stay long (10 years max)
. no sound
. Dot matrix
. Sounds
. Railway, banks
. Slow compared to thermal
. Processors
. I/O devices
. Monitors
. CAD File Format
. 2D (X and Y axis) and 3D (X, Y and Z axis)
. 2D >> DXF, DWG (Nutral Formats)
. 3D >> STP, IGS (Nutral Formats)
. DXF
. Drawing xChange Format
. OPen source
. Previously using ASCII for number format, now using ASCII and Binary
. Zoom upto 16 decimals after dot
. 256 colors use for display
. DWG
. Drawing
. File size DWG < DXF
. Dynamic bocks
. Need permissions from autodesk
. SIP
. Created based on the loopholes of IGS
. Upgraded to solids
. Usage SIP >> IGS
. IGS
. US Airforce created
. Still continues surfaces
. File Sizes
. Uses in bits and bytes
. Images, Audio, Video
. bits,bytes,KB,MB,GB,TB,PB
. Image File Formats
. Vectors and Raseters
. Rasters
. JPEG, GIFF, PNG, BMP, TIFF
. Pixel oriented images
. JPEG is better to use compared to others
. JPEG(Joint Photograpic expert group) is lossy compression, other are lossless compression
. GIF( Graphic image format) is like animation type
. PNG (Portable N/w Graphics) minly used as tranparent
. BMP Consumes more data bcoz more clarity and no loss in data
. Vectors
. SVG, AI, PDF
. By using formulas(lines and shapes) it will create the images
. Scallable - Full clarity if zoom also
. Create by using XML
. Proximity
. Grouping related items together
. Eg. Vegitable Market, Bus stop - busses will stop depends on location to go, Google page - All, images, videos,maps.
====== Need to Check ======
. Morse code is stil using?
. On what bases prits pages/min varies in differnet lasers?
. is there any posibility to print large pages in thermal
. Check DXF Format Structure
. How to create a Vector images
