Human computer interaction is a discipline concerned with the design, evaluation and implementation of interactive computing systems for human use. If the interface is well designed, it will allow the systems functionality to support the user’s task. This unit tracks the development path of human computer interaction from the command line mode to hyperlinks, hypermedia, voice user interface etc. Here we have discussed about different perspectives of communication with computer. Humans communicate with computers in many ways, and the interface between humans and the computers they use is crucial to facilitating this interaction. Different perspectives of human computer interface are human perspective, computer’s persona, user interface and interactions etc. To communicate with computers, we require different kind of input and output devices are available. Controls are the software elements, usually shown on a display, which you use to set preferences and make choices. Some familiar cont...

Embedded systems are basic electronic devices used to control, monitor or assist the operation of equipment, machinery or a plant. The choice of word “embedded” reflects the fact that these are integral part of the system. Uses of embedded system in our real life are increasing day by day. Children need such systems to play video games and to operate chocolate vending machine, Housewives need embedded systems for microwave, TV, music system, and other system appliances. Here we will discuss about basics of embedded system: its uses, its components, its basic requirements in terms of Hardware and Software and support of Programming Languages. We will also highlight some application of embedded system in our real life scenario at the end of this unit. Embedded system is a kind of computer system or computing device that performs a dedicated function and/or is intended for use with a specific embedded software application. It has been found that such systems are not usable as a commercial...

Here we introduces some of the Information Technology (IT) projects as well as those projects which use IT in India. It describes some of the projects that are completed as well as under implementation by National Informatics Centre (NIC). Similar topics are dealt with in the case of ERNET also. The impact of Broadband is significant across the Country. The projects that are using Broadband are introduced in one of the sections. Finally, SWAN is introduced and the list of projects that are completed/under implementation across various states are listed. There are a large number of IT projects across India. Organizations like NIC, ERNET are playing major role in implementing IT projects. Broadband has created a major impact across the Country. Large number of people in the Country have access to Internet through different ways. SWAN is implemented aggressively across different states and it computerizes most of the activities of the State so that the citizens across the concerned state ...

In today’s technical era, revolution in business takes place with the foreword of Internet technologies. These Internet technologies are necessary parts for the screen of today’s networked management. Therefore, there is a growing need for all those interested in doing business, management and computerized accountancy to understand the concept and scope of this technology and the way it is used to provide information for various functions in business. When computer technology turns out to be further extensively obtainable in the late 1950s and early 1960s, there was an increased eagerness for information systems to augment management decision processes. Which later converted into a nomenclature known as MIS (Management Information System). MIS is viewed and used at many levels by management and has turned out to be the favourite software engine for the development of IT in most recent years. This module throws some light on Management Information System, its application, and experience...

 An integrated set of components for collecting, storing, processing, and communicating information is called information system. Business firms, other organizations, and individuals in contemporary society rely on information systems to manage their operations, compete in the marketplace, supply services, and augment personal lives. For instance, modern corporations rely on computerized information systems to process financial accounts and manage human resources; municipal governments rely on information systems to provide basic services to its citizens; and individuals use information systems to study, shop, bank, and invest. As major new technologies for recording and processing new capabilities have appeared, the invention of movable type in the mid15th century and the creation of the portable typewriter at the end of the 19th century are but two examples. Each of these inventions led to a profound revolution in the ability to record and disseminates information. The first larg...

 Earlier we had discussed the concept of E-Governance which includes the computerization of records, right to information, availability of information on the web complaint handling etc.. Now we will define the online educational System and its features. Education is one of the main keys to economic development and improvements in human welfare. As global economic competition grows sharper, education becomes an important source of competitive advantage, closely linked to economic growth, and a way for countries to attract jobs and investment. In addition, education appears to be one of the key determinants of lifetime earnings. Countries therefore frequently see raising educational attainment as a way of tackling poverty and deprivation. In developing countries, education is also linked to a whole batch of indicators of human development. Education of women influences the health of children and family size. The experience of Asian economies in particular in the past two decades has ...
