Modern surface-mount electronic components on a printed circuit board, with a large integrated circuit at the top.
The field of electronics is a branch of physics and electrical engineering that deals with the emission, behaviour and effects of electrons using electronic devices. Electronics uses active devices to control electron flow by amplification and rectification, which distinguishes it from classical electrical engineering, which only uses passive effects such as resistance, capacitance and inductance to control electric current flow.

He was one of the first inventors to apply the principles of mass production to the process of invention, and can therefore be credited with the creation of the first industrial research laboratory. Edison is considered one of the most prolific inventors in history, holding 1,097 U.S. patents, as well as many patents in the United Kingdom, France, and Germany. Related portalsSelected article
Many e-readers, devices meant to replace traditional books, utilize electronic paper for their displays in order to further resemble paper books; one such example is the Kindle series by Amazon.
Electronic paper, also sometimes electronic ink, e-ink or electrophoretic display, are display devices that mimic the appearance of ordinary ink on paper. Unlike conventional flat panel displays that emit light, an electronic paper display reflects ambient light like paper. This may make them more comfortable to read, and provide a wider viewing angle than most light-emitting displays. The contrast ratio in electronic displays available as of 2008 approaches newspaper, and newly (2008) developed displays are slightly better. An ideal e-paper display can be read in direct sunlight without the image appearing to fade. Many electronic paper technologies hold static text and images indefinitely without electricity. Flexible electronic paper uses plastic substrates and plastic electronics for the display backplane. Applications of electronic visual displays include electronic shelf labels and digital signage, time tables at bus stations, electronic billboards, smartphone displays, and e-readers able to display digital versions of books and magazines.

Consumer showcaseDell Computer's Inspiron laptop brand is a range of computers targeted at the consumer market. Current models in the range include the E1501/1501, E1405/640m, E1505/6400 and, E1705/9400. Some Inspiron machines offered in the past have been modified to become a higher or lower quality machine. An example of this is the first-generation Inspiron XPS and Inspiron 9100 (2004). Both machines shared the same options, Dell marked the XPS as an "ultimate gaming machine", while marking the 9100 as a "desktop replacement".
