Videoconferencing is a highly useful technology for real time telemedicine and telenursing applications, such as diagnosis, consulting, prevention, treatment, and transmission of medical images.[65] With videoconferencing, patients may contact nurses and physicians in emergency or routine situations; physicians and other paramedical professionals can discuss cases across large distances. Rural areas can use this technology for diagnostic purposes, thus saving lives and making more efficient use of health care money. For example, a rural medical center in Ohio used videoconferencing to successfully cut the number of transfers of sick infants to a hospital 70 miles (110 km) away. This had previously cost nearly $10,000 per transfer.[66] Special peripherals such as microscopes fitted with digital cameras, videoendoscopes, medical ultrasound imaging devices, otoscopes, etc., can be used in conjunction with videoconferencing equipment to transmit data about a patient. Recent developments in mobile collaboration on hand-held mobile devices have also extended video-conferencing capabilities to locations previously unreachable, such as a remote community, long-term care facility, or a patient's home.[67]
Business
Videoconferencing can enable individuals in distant locations to participate in meetings on short notice, with time and money savings. Technology such as VoIP can be used in conjunction with desktop videoconferencing to enable low-cost face-to-face business meetings without leaving the desk, especially for businesses with widespread offices. The technology is also used for remote work. One research report based on a sampling of 1,800 corporate employees showed that, as of June 2010, 54% of the respondents with access to videoconferencing used it "all of the time" or "frequently".[68][69] Intel Corporation have used videoconferencing to reduce both costs and environmental impacts of its business operations.[70] Videoconferencing is also currently being introduced on online networking websites, in order to help businesses form profitable relationships quickly and efficiently without leaving their place of work. This has been leveraged by banks to connect busy banking professionals with customers in various locations using video banking technology.
Videoconferencing on hand-held mobile devices (mobile collaboration technology) is being used in industries such as manufacturing, energy, healthcare, insurance, government, and public safety. Live, visual interaction removes traditional restrictions of distance and time, often in locations previously unreachable, such as a manufacturing plant floor thousands of miles away.[71] In the increasingly globalized film industry, videoconferencing has become useful as a method by which creative talent in many different locations can collaborate closely on the complex details of film production. For example, for the 2013 award-winning animated film Frozen, Burbank-based Walt Disney Animation Studios hired the New York City-based husband-and-wife songwriting team of Robert Lopez and Kristen Anderson-Lopez to write the songs, which required two-hour-long transcontinental videoconferences nearly every weekday for about 14 months.[72][73][74][75] With the development of lower-cost endpoints, the integration of video cameras into personal computers and mobile devices, and software applications such as FaceTime, Skype, Teams and Zoom, videoconferencing has changed from just a business-to-business offering to include business-to-consumer (and consumer-to-consumer) use.
Although videoconferencing has frequently proven its value, research has shown that some non-managerial employees prefer not to use it due to several factors, including anxiety.[76] Some such anxieties can often be avoided if managers use the technology as part of the normal course of business. Remote workers can also adopt certain behaviors and best practices to stay connected with their co-workers and company.[77][better source needed] Researchers also find that attendees of business and medical videoconferences must work harder to interpret information delivered during a conference than they would if they attended face-to-face.[78] They recommend that those coordinating videoconferences make adjustments to their conferencing procedures and equipment.

A computer ( English : computer — "calculate") is an automatic device that works according to a predetermined program . Electronic calculator(EHM) is the same term. However, in addition to performing computer calculations, its function is much wider. Several generations of computers can be shown in the development of EHMs. These generations differ from each other in terms of types of elements, constructive-technological features, logical structure, software support, technical details, ease of use of equipment. In the first generation of computers (Ural-1, Minsk-2, BSEM-2), the main element was an electronic lamp, so it occupied a very large space. Then a computer using transistors instead of this lamp (Razdan-2, M-220, Minsk-22, etc.), a computer using integrated circuits (IBM-360, 1BM-370, ( USA ), YESEVM ( Russia) and others, personal computers with integrated circuits with a high level of integration appeared. The concept of a personal computer (micro and micro EHM) began to spread widely from the end of the 70s of the 20th century. Later generations of the personal computer used microelectronics and biocircuits; their size has shrunk to the size of a book, and their mass has decreased to 3.5 kg. In 1981, the IBM company began to develop more advanced models of the personal computer. Later, other companies introduced the PC with IBM, and Apple introduced the Macintosh (pronounced: "Macintosh") or simply called "maki" created the computer. At the beginning of the 21st century, there were tens of millions of personal computers, about 1 million EHMs (including several tens of super EVMs) in the world. Computers differ from each other in the composition and description of the components used to solve problems. A computer with powerful devices is used to solve complex problems, and a computer with a typewriter is used to print documents. From any computer system unit, monitor and keyboardwill consist of Other devices are connected as needed.
