Even before it was installed‚ officers were already upset that their input was not asked about the design of the interface; nobody asked their opinion and suggestions for the creation of the new system. The software itself had way too many complications. Officers were not satisfied at all with it. Some of the

MOLETRONICS-“an invisible technology” ABSTRACT As a scientific pursuit‚ the search for a viable successor to silicon computer technology has garnered considerable curiosity in the last decade. The latest idea‚ and one of the most intriguing‚ is known as molecular computers‚ or moletronics‚ in which single molecules serve as switches‚ "quantum wires" a few atoms thick serve as wiring‚ and the hardware is synthesized chemically from the bottom up. The central thesis of moletronics

Describe in detail any five multimedia input devices ? Multimedia is a mixture of different media -- such as text‚ video‚ audio‚ graphics and data -- that work together to provide you with all of the computing functions you need. To use multimedia‚ you rely on a team of input and output devices that are responsible for both transmitting and receiving information between you and the computer. Monitor Your monitor is either a separate component of your computer‚ like with a desktop version‚ or is

well-established techniques. A few examples of these include stereoscopic imaging via shutter or polarized glasses‚ as well as auto-stereoscopic technologies composed of lenticular screens directing light from a conventional display‚ or real-imaging devices utilizing concave mirror arrangements. All of these technologies suffer convergence and accommodation limitations. In order to resolve this visual limitation‚ the image and its perceived location must coincide spatially.

decode four binary-coded inputs into one of sixteen mutually exclusive outputs when both the strobe inputs‚ G1 and G2‚ are LOW. The demultiplexing function is performed by using the 4 input lines to address the output line‚ passing data from one of the strobe inputs with the other strobe input LOW. When either strobe input is HIGH‚ all outputs are HIGH. These demultiplexers are ideally suited for implementing high-performance memory decoders. All inputs are buffered and input clamping diodes are provided
