Short Note on Disk drive and CD-Writer

Short Note on Disk drive and CD-Writer Points : short note on disk drive and cd-writer, write a short note on disk drive and cd-writer Disk Drive: Disk drive is a peripheral device that reads or writes the disks (hard disks, floppy disks, etc) that store information. Disk derives are called “Storage devices” because they store information on portable or permanent disks. The drive contains a motor to rotate the disk at a constant rate and one or more read/write heads, which are positioned over the desired track.

Plotters and types of Plotters

Plotters and types of Plotters Points : plotters and types of plotters, types of plotters, pen plotters, electrostatic plotters Plotters Plotter is a special kind of output device that prints graphics on papers, which includes drawing, graphs, making maps, plotting engineering drawings and machine component. Plotters differ from printer in that they draw lines using a pen. As a result, they can produce continuous lines, where as printers can only simulate lines by printing a closely spaced series of dots.

Printer and its Types

Printer and its Types? Points : define printer and its types, printer, impact printers, non-impact printers, difference between impact and non-impact printer, impact vs non-impact printer, comparison between impact and non-impact printer, discuss some examples of impact printer, daisywheel, dot matrix, line printer, discuss some examples of non-impact printer, ink-jet, laser, lcd and led, thermal printer Printer Printer is a device that accepts text and graphic output from a computer and transfers the information to paper, usually to standard size sheets of paper. Printers are sometimes sold with computers, but more frequently are purchased separately. Printers vary in size, speed, sophistication, and cost.

There are many different types of printers. In terms of the technology utilized printers fall into basic two categories.
Impact Printers Impact printers include all printers that work by striking an ink ribbon. Daisy wheel, dot matrix and line printers are impact printers. Impact printers are much nosier than other printers.

Why Monitor is Called CRT

Why Monitor is Called CRT Points : why monitor is called crt, why monitor is called crt? and discuss its types, monitor, basic types of monitor, types of monitor (colourwise, monochrome, gray-scale, colour Monitor To display results or output from computer, a T.V like device is used and called Monitor. Monitor assists during input from the keyboard. it also displays all normal and error messages. The displayed output is called a “Soft Copy” of information. The monitor and the VDU is also known a CRT(Cathode Rays Tube) because it has an electronic tube. The electronic guns send beam of electronic to trace regular pattern horizontal lines or data on the phosphor that coat the screens surface.
