Compare and contrast packet and circuit switching in 250 to 300 words. Which is more commonly used? What are the advantages and disadvantages of each? Packet-switched networks move data in separate‚ small data blocks‚ or packets as they are more commonly known‚ based on the destination address in each packet. When received‚ the packets are reassembled in the proper sequence to make up the message. The packets are not dependent on any one path or connection‚ and can take as many paths as necessary

the cost and also require complicated interfacing circuitry around it. But this smoke alarm circuit uses readily available photon-coupled interrupter module as smoke detector. The functioning of this smoke alarm is to continuously detect smoke and automatically activate the alarm in case of dense smoke. Loud sound is heard continuously indicating the presence of smoke till smoke clears. After this‚ the circuit is automatically reset for further detection of smoke provided it is kept in power ON condition

wireless networks is expected to positively impact the global industry. The use of FPGA in medical imaging applications is expected to be a growth opportunity‚ since they are reprogrammable and reusable. The presence of Application-Specific Integrated Circuits (ASICs) as viable FPGA substitutes may hamper market growth over the next six years.

FIELD-PROGRAMMABLE GATE ARRAY A field-programmable gate array (FPGA) is an integrated circuit designed to be configured by a customer or a designer after manufacturing—hence "field-programmable". The FPGA configuration is generally specified using a hardware description language (HDL)‚ similar to that used for an application-specific integrated circuit (ASIC) (circuit diagrams were previously used to specify the configuration‚ as they were for ASICs‚ but this is increasingly rare). Contemporary

With the development of Computers and information technology came talk of a new environmentally friendly era. The need to create and store documents on paper would be gone‚ along with the need to travel from city to city to conduct business meetings. The developers of computers sold Government Originations and Corporate America on these cost saving concepts. The promises made by computer developers proved to be somewhat true‚ especially given the wide spread deployment and use of Internet and email

Installation of surveillance camera systems as a way to deter crimes or criminal acts has gained traction in recent years. In some countries‚ surveillance camera systems – also known as closed circuit television (CCTV) cameras – have also installed in educational institutions as a security measure to address fears for the safety of the students (Hope‚ 2004; Corpuz‚ 2011). The trend‚ however‚ did not stop. From halls and corridors‚ some education institutions have started to install cameras inside

our world today‚ cellphones‚ and laptops are widely used. For some‚ these things are so important especially for students and employers who work from office. These devices are usually operated with battery. A DC to DC converter is an electronic circuit which converts a source of direct current (DC) from one voltage level to another. DC is not easily being stepped up or down. One of the applications of this DC to DC converter is stepping down the voltage. In this experiment a Step down DC to DC
