Parallel processing Parallel processing is the simultaneous processing of the same task on two or moremicroprocessors in order to obtain faster results. The computer resources can include a single computer with multiple processors, or a number of computers connected by a network, or a combination of both. The processors access data through shared memory. Somesupercomputer parallel processing systems have hundreds of thousands of microprocessors.
Vector processing
"A vector processor, or array processor, is a CPU design wherein the instruction set includes operations that can perform mathematical operations on multiple data elements simultaneously. This is in contrast to a scalar processor, which handles one element at a time using multiple instructions. The vast majority of CPUs are scalar (or close to it). Vector processors were common in the scientific computing area, where they formed the basis of most supercomputers through the 1980s and into the 1990s, but general increases in performance and processor design saw the near-disappearance of the vector processor as a general-purpose CPU.

A vector of magnitude 3 cannot be added to a vector of magnitude 4 so the magnitude of the resultant is?
7
How will you multiply a vector by positive number?
A positive scalar multiplied by a vector, will only change the vector's magnitude, not the direction. A negative scalar multiplied by the vector will reverse the direction by 180°.
What is the differeance between Rasta and vector?
Raster images are defined in pixels. ie At every x,y location, whether it is black or white. Vector images are defined by lines. eg From x,y to X,Y. Any pixel that lies between these points on a white background becomes black. It is easier to convert Vector images to Raster images, rather than the other way. Vector images are sometimes smaller (in data size). eg If the image contains one line, then the amount of data needed to store this is smaller than having to define every pixel in the image regardless of whether it is relevant. Vector images can be scaled smaller and larger without any significant loss of detail. Raster images that have been made smaller lose clarity and cannot then be made larger to improve the quality.
Is Photoshop a raster or vector based program?
raster
What is the difference between a Bitmap and a Vector image?
Bitmap graphics are made up of pixels of different colours whereas vector graphics are made up of objects. Bitmap graphics can be edited by individual pixels whereas vector graphics can be edited by individual objects.
