Hardware and Software
Used to create and edit graphic images
Hardware and Software Pacakges
Graphics card
The graphics cared is used to output visuals and graphics that are received from the CPU to a VDU (Visual Display Unit) The VDU is usually Connected Directly to the graphics on the Motherboard
RAM
Referred to as main memory, primary memory, or system memory, Random Access Memory (RAM) is a hardware device that allows information to be stored and retrieved on a computer and can be opened at any time
ROM
Rom is a type of storage unlike main memory ROM retains its content when the system is turned off and can keep information stored
CPU
Sometimes referred to simply as the central processor but more commonly called processor the CPU is the brains of the computer where most calculations take place it is the brain of the computer itself and completes actions that take place
Hard drive
Hard disk drives (also called hard drives or disk drives) is the mechanism that reads and writes data on a hard disk bigger disk drives improve performance through caching
Flash cards
A small, portable card that plugs into a computer and functions as a portable hard drive USB flash drives are to easy-to-use as they are small enough to be carried in a pocket and can plug into any computer with a USB drive
CD FLASH
a type of optical disk capable of storing large amounts of data -- up to 1GB, although the most common size is 650MB a single CD-ROM has the storage capacity of 700 floppy disk , enough memory to store about 300,000 text pages
Input Devices
Mouse
A mouse is a input device that allows a user to scroll over pages and click links to other pages it is the main device what helps you navigate around the web
Keyboard
A keyboard is a input device that allows the users to type the size of the paper size they would like to use when creating a project
Vector & Bitmap
Vector images are made up of objects. The objects are small in file size so that a computer does not need a lot of memory for the detail object. Because of this when you re-size vector images they do not blur or lose their quality.
Lossless and lossy
Lossless and lossy compression are terms that describe whether or not, in the compression of a file, all original data can be recovered when the file is uncompressed. With lossless compression, every single bit of data that was originally in the file remains after the file is uncompressed.
File Types
JPEG
relatively small file sizes
supported by a wide range of software programs
does not support transparency
does not preserve layers
SVG
Short for scalable vector graphics, a vector graphics file format that enables two-dimensional images to be displayed in XML pages on the Web
BMP
Bit mapped graphics are often referred to as raster graphics. The other method for representing images is known as vector graphics or object oriented graphics. With vector graphics, images are represented as mathematical formulas that define all the shapes in the image. Vector graphics are more flexible than bit-mapped graphics because they look the same even when you scale them to different sizes. In contrast, bit-mapped graphics become ragged when you shrink or enlarge them.
GIF
Stands for graphic interchange format it is a bit map used by the world web GIF supports colors and various resolutions it also includes data compression because it is limited to certain amount of colors more effective for scanned images
PNG
portable network graphics ping is a new bit mapped graphics format similar to gif png is the third most standard graphics supported by the web allows you to control transparency also known as opacity on images themselves also png does not like animation like gif does
PSD
once not finished a file in Photoshop it will become a PSD file you can not upload PSD files on the web as they would be to big until finished and compressed
TIFF
TIFF is a computer file format for storing raster graphics images, popular among graphic artists, the publishing industry, and photographers. The TIFF format is widely supported by image-manipulation applications
