Computer Hardware, Systems Software & Networking Essay

Computer Hardware, Systems Software & Networking - Essay Example U) and its associated registers that hold the data that is being operated upon and a memory area referred to as Random access memory (RAM) in which any memory location can be read or written upon. The CPU is capable of differentiating the type of content that is stored in memory i.e. whether they are instructions or data. Schematic presentation of the sequential architecture can be exhibited by the figure on the left. A raster graphic is created by combining many small points of information. An easy way to think of a raster graphic is to picture an image in a comic book that is made up of many small dots of color. Depending on the number of dots, the quality of the picture is determined. The raster graphic arrangement can also be referred to as an arrangement of an array of pixels that combine to display an image. A vector graphic is also a picture but the information is communicated in another way. To use another childish example, a vector graphic is like a dot-to-dot. It uses geometrical primitives such points, lines, curves and shapes or polygons which are all based on mathematical equations to represent images. Thus, it has important points that determine what the picture will look like. In Flash, we create vector graphics when we turn pictures into symbols. Since the computer only has to store the information about the key points in the graphic, the size of these images is much smaller than that of a raster graphic which stores information about each individual point. For conversion to Hexa decimal we have to make groups of 4 digits. For integer portion the orientation is right to left with padded zeros on the left most sides. For fractional portion the orientation of grouping is reversed ie from right to left considering point (.) as origin. The chart is given as reference. 6. Reduced instruction set computers provide a large number of general-purpose registers and very few memory access instructions. Most instructions use registers instead of
