Output Device can produce the final product of machine processing into a form usable by humans. It provides man to machine communication. Keyboard is most common input device is used today. The data and instructions are input by typing on the keyboard. The message typed on the keyboard reaches the memory unit of a computer. Apart from alphabet and numeral keys, it has other function keys for performing different functions. The mouse is rolled over the mouse pad, which in turn controls the movement of the cursor in the screen.

Choose the correct option and mark your choice against the corresponding question number in the given answer sheet by darkening the corresponding circle with a lead pencil. Now they are also used with nonportable desktop computer systems because they occupy less table space. Non-impact printers. Can print many special characters, different sizes of print, and graphics such as charts and graphs Are non-impact printers Most laser printers are monochrome, but color laser printers are also available Low speed laser printers can print 4 to 12 pages per minute. Produce audio output by selecting an appropriate audio output from a set of pre-recorded audio responses Applications include audio help for guiding how to operate a system, automatic answering machines, video games, etc.

A peripheral device is generally defined as any auxiliary device such as a computer mouse or keyboard, that connects to and works with the computer in some way. RAM—random access memory—straddles the line between peripheral and primary component; it is technically a storage peripheral, but is required for every major function of a modern computer and removing the RAM will effectively disable any modern machine. Many new devices such as digital watches, smartphones and tablet computers have interfaces which allow them to be used as a peripheral by a full computer, though they are not host-dependent as other peripheral devices are. According to the most technical definition, the only pieces of a computer not considered to be peripherals are the central processing unit, power supply, motherboard, and computer case.

An input device sends information to a computer system for processing , and an output device reproduces or displays the results of that processing. Input devices only allow for input of data to a computer and output devices only receive the output of data from another device. Most devices are only input devices or output devices, as they can only accept data input from a user or output data generated by a computer. For example, as shown in the top half of the image, a keyboard sends electrical signals, which are received as input. Those signals are then interpreted by the computer and displayed, or output , on the monitor as text or images.

Meeting the every-citizen interface ECI criteria described in Chapter 2 will require advances in a number of technology areas. Some involve advances in basic underlying display and interface technologies higher-resolution visual displays, three-dimensional displays, better voice recognition, better tactile displays, and so on.

Сьюзан наклонилась и подняла. Это было письмо. Дорогие друзья, сегодня я свожу счеты с жизнью, не в силах вынести тяжести своих грехов… Не веря своим глазам, Сьюзан медленно читала предсмертную записку. Все это было так неестественно, так непохоже на Хейла, а список преступлений больше напоминал перечень сданного в прачечную белья. Он признался во всем - в том, как понял, что Северная Дакота всего лишь призрак, в том, что нанял людей, чтобы те убили Энсея Танкадо и забрали у него кольцо, в том, что столкнул вниз Фила Чатрукьяна, потому что рассчитывал продать ключ от Цифровой крепости.
