Xerox‚ during this time‚ was a power house of innovation‚ many aspects of the modern computer; the mouse‚ laser printers‚ Ethernet‚ and color graphics were all founded. In 1974 an employee of Xerox‚ Nicholas K. Sheridon invented the basis for modern electronic paper technology‚ the Gyricon. The Gyricon has many of the same properties as paper; it is flexible‚ contains an image‚ but it can also by erased and rewritten thousands of times. In the nineties‚ as the personal computer became more popular more

1. Introduction to Network Devices All networks are made up of basic hardware building blocks to interconnect network nodes‚ such as Network Interface Cards (NICs)‚ Bridges‚ Hubs‚ Switches‚ and Routers. In addition‚ some method of connecting these building blocks is required‚ usually in the form of galvanic cable (most commonly Category 5 cable). Less common are microwave links (as in IEEE 802.12) or optical cable ("optical fiber"). An ethernet card may also be required. Network interface cards

INTRODUCTION Electronic Media Electronic media are that utilize electronics or electromechanical energy for the end user (audience) to access the content. This is in contrast to static media (mainly print media)‚ which are most often created electronically‚ but don’t require electronics to be accessed by the end user in the printed form. The primary electronic media sources familiar to the general public are better known as video recordings‚ audio recordings‚ multimedia presentations‚ slide

Electronics engineering‚ [1] also referred to as electronic engineering[2][3] is an engineering discipline which uses the scientific knowledge of the behavior and effects of electrons to develop components‚ devices‚ systems‚ or equipment (as in electron tubes‚ transistors‚ integrated circuits‚ and printed circuit boards) that uses electricity as part of its driving force. Both terms denote a broad engineering field that encompasses many subfields including those that deal with power‚ instrumentation

ELECTRONIC WARFARE INTRODUCTION 1. The advent of World War 1 saw two new dimensions being added to warfare one of air and other of under water. But probably the most important element to be put to use for war in the 20th century was the use of radio waves and the associated electronics. They were used first in radio communication and later on in the fields of radar. Under the stimulus of war‚ technology advanced rapidly and new systems provided greater ranges‚ greater precision and greater capacity

Assignment no. 2 Ujjwal Dahiya Electronic sensors Sensors are sophisticated devices that are frequently used to detect and respond to electrical or optical signals. A Sensor converts the physical parameter (for example: temperature‚ blood pressure‚ humidity‚ speed‚ etc.) into a signal which can be measured electrically. Classification based on property is as given below: Temperature - Thermistors‚ thermocouples‚ RTD’s‚ IC

Page 1 of 4 Expansion Devices I. Introduction Expansion devices are basic components of a refrigeration system which carry out two major purposes: (1) the pressure reduction from the condenser to evaporator pressure and (2) the regulation of refrigerant flow into the evaporator. These expansion devices can be generally classified into two types which are namely the fixed opening type (flow area is fixed) and the variable opening type (flow area changes correspondingly with a change in mass
