positive impact that information tecnology have on the society

That make possible to connect 6 billion peoples all overr the world regardless the religion, nationality, color and language.

Information technology has evolved over time through the contributions of many individuals and organizations. It does not have a single inventor, but rather has been built upon the work of various innovators including Ada Lovelace, Charles Babbage, Alan Turing, and many others who have made significant contributions to the field.

Information plays a crucial role in today's careers by enabling decision-making, problem-solving, and innovation. It helps professionals stay up-to-date with industry trends, make strategic business choices, and communicate effectively with colleagues and clients. Access to accurate and relevant information can give individuals a competitive edge in their respective fields.

Some disadvantages of educational technology include potential distractions for students, increased screen time leading to health concerns, and the possibility of unequal access to technology resources among students. Additionally, there may be challenges in effectively integrating technology into the curriculum and ensuring that it enhances learning outcomes.

Excessive use of ICT can lead to decreased face-to-face interactions, social isolation, and reduced physical activity. It may also contribute to feelings of loneliness and anxiety due to over-reliance on virtual communication.

Because everything has been advance, too much quick and fast. For example if you want to search or read books then you can use internet and find a lot of digital libraries in a fraction of seconds.

The information age refers to a period characterized by the widespread availability and use of information and communication technologies, whereas the digital age specifically focuses on the impact and integration of digital technologies in various aspects of society. In essence, the digital age is a subset of the larger information age, emphasizing the role of digital technologies in shaping modern society.

Absolutely Yes. Today information technology provide commutation facilities to contact each other like they in a single room. as an example using video conferencing , teleconferencing are famous example to them. Today Google (maps.google.com)map , street view etc are provide facilities to visit the earth as we are in the places that we want to visit. Within few seconds you can visit different countries as well as communicate with persons are living in different countries. hence we can accept the answer "Yes" for the above Save question.

Knowledge-Based Systems

A knowledge-based system is a computer program that reasons and uses knowledge to solve complex problems. Traditionally, computers have solved complex problems using arithmetic algorithms created by programmers. With knowledge-based systems, human knowledge is captured and embedded explicitly within a program in a symbolic format.

Expressing knowledge as rules and heuristics has two particular advantages over previous software development technology. Not only can explicit knowledge be trapped in the computer, but so can implicit knowledge, which is useful and potentially very profitable. The other advantage is that knowledge that exists in the form of rules can be captured in that form, without having to be converted by teams of analysts and programmers into data definitions and procedures.
Types of Systems

One way that knowledge-based systems can be classified is by the kind of conclusions they produce. Some interpret the available evidence and produce diagnoses-for example, to explain the reason for a machine breakdown. Others interpret the available evidence but offer a prediction, such as the likelihood of a particular applicant for a loan becoming a slow-payer or a defaulter. Some systems address design questions, proposing the form or layout of a product or the configuration of components. Some are related to industrial engineering matters such as the procedure for assembling the components.

However, not all knowledge-based systems are so ambitious. Many merely use the captured rules to determine to which class a particular example belongs. For example, a system might determine whether a particular person is, or is not, entitled to a particular government benefit, an entry visa, or permanent residence.
Development Techniques

During the development of a knowledge-based system, knowledge is extracted from one or more domain specialists, or people who have specialized knowledge in the relevant domain. The knowledge is commonly expressed in the form of antecedent-consequent (IF THEN) rules. In some cases it may be possible for the domain specialist to feed the knowledge directly into the system, but usually an intermediary knowledge engineer captures it using supporting software.

Once the system is developed, a user consults it to find information about some event or situation within a problem domain. The software draws inferences by applying the explicit rules elicited by the expert and the more general implicit rules derived by the system. A result is provided to the user in the form of a diagnosis, prognosis, recommendation, or decision, depending on the nature of the application. In addition, the user may request an explanation of the argument the software used to reach its conclusion.

Knowledge-based systems usually contain three components: a human-computer interface , a knowledge base, and an inference engine program. The human-computer interface is where the user formulates queries, which the knowledge-based system uses to solicit further information from the user and explain to the user the reasoning process employed to arrive at an answer. The knowledge of one or more human experts in a specific field or task is stored in the knowledge base. The knowledge base is set up as an intelligent database-it can usually manipulate the stored information in a logical, natural, or easy-to-find way. It can conduct searches based on predetermined rules of defined associations and relationships, as well as by the more traditional data search techniques.

The knowledge base is usually made up of factual knowledge, and sometimes even heuristic knowledge. Factual knowledge consists of information that is commonly shared, found in textbooks or journals, or agreed upon by humans knowledgeable in a specific field or task. Heuristic knowledge, on the other hand, is experiential knowledge of performance; it is the knowledge behind an educated guess.

The inference engine of an expert system is usually set up to mimic the reasoning, or problem-solving ability, that the human expert would use to arrive at a conclusion. The inference engine simulates the evaluation process of relating the information and rules in the knowledge base to the answers to a series of questions given by the operator. Following this model, an expert system will receive propositions, or answers to a certain line of questions, and then try to use its inference engine to process the information into rules. It will compare the propositions to the facts and rules registered in its knowledge base.
Current and Future Uses

The primary goal of knowledge-based systems is to make expertise available to decision-makers who need answers quickly. Expertise is often unavailable at the right place and the right time. Portable computers loaded with in-depth knowledge of specific subjects can bring years' worth of knowledge to a specific problem. The first knowledge-based or expert system, Dendral, was developed in 1965 by Edward Feigenbaum (1936-) and Joshua Lederberg of Stanford University in California and was used to analyze chemical compounds. Since 1965, knowledge-based systems have enhanced productivity in business, science, engineering, and the military. They also attempt to predict the weather, stock market values, and mineral deposit locations; give a medical diagnosis; dispense medication; and evaluate applications and transaction patterns.

Knowledge-based systems appear to have a great deal of potential, but they also face some challenges. These include the shortage of knowledge engineers with necessary skills; the relative immaturity of many of the available tools; and overly specific problem domains. Most knowledge-based systems deal with very specific problem domains, and therefore do not undertake or support a complete activity, but rather one or two tasks within a sequence or cluster of tasks. The benefit that such software offers is not necessarily to automate the process completely and cut costs drastically, but to assist the user to complete the activity faster, somewhat more cheaply, and probably more accurately.

The right to privacy on the internet and in real life are very important, something those numb-skull media boneheads can't get into there head! There have been celebrities that have gone mad because the media won't f-ing well go away!

Indians were more advanced than Virginia colonists in agriculture and farming techniques, as they cultivated crops like maize, beans, and squash using sustainable methods like crop rotation. They also had advanced knowledge of medicinal plants and natural resources, which the colonists learned from them.

The four attributes of communication are sender, receiver, message, and feedback. Sender is the one who initiates the communication, receiver is the intended audience, message is the information being conveyed, and feedback is the response or reaction from the receiver.

advantage is "ARPANET made possible collaborations between people who were thousands of miles apart"

disadvantage is" it was difficult to get connected to as it required "political connections'', and a large amount of money.

Self-learning is achieved through Compact discs. Also, interactive learning online or offline by the use of e-books and e-journals make this possible. Besides, Television channels and audio broadcast facilitate self-learning.

I suppose it depends on your perspective. From an IT workers perspective it's both a blessing and a curse. On the one hand, they'd have no employment without it. On the other hand, they have to deal with people who use IT on a daily basis without knowing what they're doing. As a whole, however, I'd say IT is more of a blessing for society as a whole, than a curse.

To join the CBI or CID in India, typically one needs to be a part of the Indian Police Service (IPS) or state police services. To become an IPS officer, a candidate must appear for the Civil Services Examination conducted by the Union Public Service Commission (UPSC). While a background in information technology can be beneficial, candidates need to clear the required exams and meet the eligibility criteria set by the government for the IPS.

The emergence of information technology has revolutionized communication, access to information, and the way we work. It has created new job opportunities, facilitated global connections, and increased efficiency in many industries. However, it has also raised concerns about privacy, security, and the digital divide between those who have access to technology and those who do not.
