Final answer:
true, Raster refers to digital images composed of pixels, which does include formats like JPEG and TIFF, and refers to data stored as pixels or cells; therefore, the statement is true.
Step-by-step explanation:
The term raster refers to digital images that are composed of a grid of pixels, where each pixel represents a single point in the image. This contrasts with vector graphics, which use geometric shapes and paths to represent images.
Formats such as JPEG, TIFF, and various grid formats do indeed represent raster data, where the image is stored in a pixel-by-pixel manner. This means that the statement is true: raster does include a variety of formats that store data as cells or pixels.
To visualize raster data, imagine a close-up of a flat screen where each pixel can be seen. Each pixel would typically be composed of red, green, and blue colors which, when combined in different intensities, create the full color range that the human eye perceives on the screen.
The statement is mostly true. The term "raster" generally refers to a data representation format where information is stored as a grid of cells or pixels. This format includes various file types like JPEG and TIFF, which are commonly used for storing raster graphics, where an image is composed of a grid of pixels.
However, the term "grid" may be more commonly associated with raster data formats used in geographic information systems (GIS), where raster grids represent spatial information, and formats like GeoTIFF are prevalent. So, while the statement is generally accurate, the term "grid" may have a specific context in GIS.
