Data transmission

Data transmission and data reception or, more broadly, data communication or digital communications is the transfer and reception of data a digital bitstream or a digitized analog signal [1] over a point-to-point or point-to-multipoint communication channel. Examples of such channels are copper wires , optical fibers , wireless communication channels, storage media and computer buses. The data are represented as an electromagnetic signal , such as an electrical voltage , radiowave , microwave , or infrared signal. Analog or analogue transmission is a transmission method of conveying voice, data, image, signal or video information using a continuous signal which varies in amplitude, phase, or some other property in proportion to that of a variable. The messages are either represented by a sequence of pulses by means of a line code baseband transmission , or by a limited set of continuously varying waveforms passband transmission , using a digital modulation method. The passband modulation and corresponding demodulation also known as detection is carried out by modem equipment.

This is the capacity of a network communications link to transmit the maximum amount of data from one point to another in a given amount of time. A1: A computer network is a group of computers linked to each other that enables the computer to communicate with another computer and share their resources, data, and applications. Wireless networks are rapidly rendering a wide range of personalized communications services as portable as cellular phones.

The approach adopted is rather straightforward; define a data network as a computer communication network that could be best understood with the help of the.

 - Она улыбнулась и села напротив шефа. Стратмор был крупным кряжистым мужчиной, чье невыразительное лицо скрывало присущие ему решительность, настойчивость и неизменное стремление к совершенству. Серые глаза светились уверенностью, с которой сочеталась профессиональная скрытность, но сегодня в них проглядывали беспокойство и нерешительность. - У вас испуганный вид, - сказала Сьюзан. - Настали не лучшие времена, - вздохнул Стратмор. Не сомневаюсь, - подумала .

 Да, конечно, - подтвердил лейтенант. Беккер постоял минуту, уперев руки в бока. Затем поднял коробку, поставил ее на стол и вытряхнул содержимое. Аккуратно, предмет за предметом, перетряхнул одежду. Затем взял ботинки и постучал каблуками по столу, точно вытряхивая камешек. Просмотрев все еще раз, он отступил на шаг и нахмурился.
