History[ edit ] The first documented computer architecture was in the correspondence between Charles Babbage and Ada Lovelacedescribing the analytical engine. When building the computer Z1 inKonrad Zuse described in two patent applications for his future projects that machine instructions could be stored in the same storage used for data, i. Johnson and Frederick P. Buchholz, by writing,  Computer architecture, like other architecture, is the art of determining the needs of the user of a structure and then designing to meet those needs as effectively as possible within economic and technological constraints.
Unlike a regular printer, the plotter can draw continuous point-to-point lines directly from vector graphics files or commands. There are a number of different types of plotters: Plotters were the first type of printer that could print with color and render graphics and full-size engineering drawings.
As a rule, plotters are much more expensive than printers. Hewlett-Packard is the leading vendor of plotters worldwide. An application need not know the names of all the modules or entry points that may be called.
For example, a charting program may be written to work with a variety of plotters, each of which is driven by a different driver package. The application can learn the name of the plotter that is currently installed on the system from another process or by looking it up in a configuration file.
This allows the user of the application to install a new plotter that did not exist at the time the application was written.
It is a device that draws pictures on paper based on commands from a computer. Plotters differ from printers in that they draw lines using a pen. As a result, they can produce continuous lines, whereas printers can only simulate lines by printing a closely spaced series of dots.
Multicolor plotters use different-colored pens to draw different colors.
They are used in engineering applications where precision is mandatory. A plotter works closely with a computer's imaging software to produce a final picture or object.
The first step in using a plotter is to enter the appropriate coordinates for where you want the image to appear on the paper. Modern software allows the user to accomplish this goal very easily by drawing lines and images with the imaging software.
Once the schematics for the image are complete, the computer downloads the coordinates to the plotter, which interprets the code and calculates the most efficient path for the pen and paper.
Newer plotters use one of two programming languages: Early plotters contained two separate pens, one that moved vertically and one that moved horizontally. These plotters were limited in terms of the complexity of the images they could produce as well as the speed at which they could operate.
Modern plotters use a sliding roller, which moves the paper against a stationary pen. A plotter pen is usually a hollow fiber rod with a sharpened end. The ink supply runs through the center of the rod and dispenses through the sharpened tip. The paper moves horizontally and vertically against the pen until the drawing is complete.Developed and Maintained by: Gursharan Singh & Maninder Kaur Browsers Supported: 8+ 4+ 10+ 4+ 4+ Resolution: × In computer engineering, computer architecture is a set of rules and methods that describe the functionality, Johnson had the opportunity to write a proprietary research communication about the Stretch, short time after the brake pedal is sensed or else failure of the brake will occur.
