The Bitcoin was designed to be the perfect virtual currency. Bitcoin is completely anonymous, cryptographically secure, and friction-less. It is also invisible to law enforcement as well as the taxman. It can be seen as the holy grail of payments for anyone trying to avoid bank fees while spending money domestically or abroad. On another note it is the perfect trading grounds for members of the underground economy, attempting to avoid law enforcement and prosecution. Although there are many pros in the use of Bitcoins, there are always cons. Nothing is perfect. The strengths of Bit coin can also be considered its weaknesses. Once the money is sent, it is sent, it was designed so that there is no trust required between buyer and seller, payment was guaranteed, as soon as it enters the account, it cannot be taken back unless the seller refunds it. Not many people are willing Continue reading

Global Impact of Information and Communication Technology (ICT)
In recent years, the evolution of the concept of training has been dazzled by the emergence and consolidation of information and communications technologies (ICT), the Internet and its implementation on the World Wide Web has facilitated access to all types of necessary information, causing a considerable increase in interactivity between people from different continents and countries of the world, providing the possibility of developing their skills and abilities for teleworking, multicultural interaction, access to information, knowledge and education with the objective of reducing the digital divide, this being the subject addressed in this article. Globalization consists of the increasing communication between the different countries of the world unifying their societies, societies and cultures markets, through a series of transformations at a global level. Communications and computing are the engine of globalization, since that advances in computing and electronic elements used for communications have been admirable in the field of global Continue reading
What is Expert System?
An expert system is an advanced computer application that is implemented for the purpose of providing solutions to complex problems, or to clarify uncertainties through the use of non-algorithmic programs where normally human expertise will be needed. Expert systems are most common in complex problem domain and are considered as widely used alternatives in searching for solutions that requires the existence of specific human expertise. The expert system is also able to justify its provided solutions based on the knowledge and data from past users. Normally expert systems are used in making business marketing strategic decisions, analyzing the performance of real time systems, configuring computers and perform many other functions which normally would require the existence of human expertise. The difference between an expert system with a normal problem-solving system is that the latter is a system where both programs and data structures are encoded, while for expert system only Continue reading
Distributed Data Processing (DDP)
Distributed database system technology is the union of what appear to be two diametrically opposed approaches to data processing: database system and computer network technologies. Database system have taken us from a paradigm of data processing in which each application defined and maintained its own data to one in which the data is defined and administered centrally. This new orientation results in data independence , whereby the application programs are immune to changes in the logical or physical organization of the data. One of the major motivations behind the use of database systems is the desire to integration the operation data of an enterprise and to provide centralized, thus controlled access to that data. The technology of computer networks, on the other hand, promotes a mode of that work that goes against all centralization efforts. At first glance it might be difficult to understand how these two contrasting approaches can Continue reading
Introduction to Quantum Computing
Quantum computing is a branch of computing that is based on the principles of quantum mechanics. Unlike classical computers, which operate on binary digits (bits) that can be either 0 or 1, quantum computers use quantum bits, or qubits, which can exist in multiple states at once. This allows quantum computers to perform complex calculations much faster and more efficiently than classical computers. The history of quantum computing can be traced back to the early 1980s, when physicist Richard Feynman first proposed the idea of using quantum mechanics to solve mathematical problems. In 1985, mathematician David Deutsch developed a theory of quantum computing that showed how a quantum computer could perform certain calculations faster than a classical computer. Since then, the field of quantum computing has rapidly evolved, and today, researchers are developing a range of quantum algorithms and applications, including cryptography, drug discovery, machine learning, and optimization problems. Quantum Continue reading
Internet of Things (IoT) in Healthcare
Internet of Things (IoT) is a revolution in computer technology and communication that aims to connect objects together through the Internet. IoT is an idea of a worldwide distributed network, that can be fit into any environment with the aim of collect object data and sending this information for storage and analysis through the internet to some other location. Internet of Things means things interact with the Internet by employing sensors, microcontrollers, and transceivers for empowering communication and is built with suitable protocol stacks which help them interacting with each other and communicating with the users, thus becoming the constitutive part of the Internet. Nowadays, the Internet is impacting several aspects of the potential user’s everyday life. IoT is a highly dynamic distributed network composed of a very large number of objects. Human beings supply most of the contents and information found on the Internet so far, whereas in IoT, Continue reading
