Bitcoin is a type of digital currency in which encryption techniques are used to regulate the generation of units of currency and verify the transfer. P2P network-based virtual currency that is traded online and exchanged into currencies. When paired with third-party services, allows users to mine, buy, sell, or accept bitcoins from anywhere in the world. The offer of transactions with relative anonymity is a significant financial power and brings changes to the future payment systems. Transactions are made with no banks interfering, so there are no transaction fees. More merchants are beginning to accept them. Every-one can buy services, goods but also criminals have a way to transfer very their in-come from illicit activities completely anonymously. While Bitcoin developers maintain Web sites providing guidance to the Bitcoin community, they do not have a centralized database or authority. The Future of Bitcoin Bitcoin will never be successful as a currency, Continue reading

What Is Data Strategy?
Data Strategy defines a set of choices and actions that, together, define a high-level course of action to achieve high-level goals. It involves business plans to use knowledge to a competitive advantage to support business objectives. A Data Strategy requires an understanding of the data needs inherent in the Business Strategy. Like many other terms, “data strategy” has several synonyms in data management. They include but are not limited to business data strategy, business data management strategy, information management strategy, business information management strategy, information strategic plan. All these terms refer to the same concept of a single, enterprise plan for the use of organizational data as an essential asset for strategic and operational decision-making. A data strategy defines the approach that the enterprise will take to manage and use its data and information to achieve its business and technology goals and to realize a competitive advantage using this asset. The Continue reading
An Overview of Real-Time Operating Systems (RTOS)
Real-Time Operating Systems (RTOS) are Operating Systems for systems operating in Real Time. These Operating Systems have functions dedicated to detecting and responding to tasks from the real world within their deadlines. Real-Time Operating Systems are systems that are subject to real time limitations and are expected to deliver services within strict time boundaries. The correctness of such systems depends not only on computational output, but also on the instant at which the system produces the output. Real-Time Operating Systems (RTOS) can be generally categorized into soft and hard real time systems. When a deadline is missed in a hard real time system, i.e. a service is not provided at the instant at which it is expected, the result would be catastrophic. Hence, hard real time systems are generally safety or mission critical. Examples of Hard Real Time Systems are, Air Traffic Control Systems, Pace makers for heart patients and Continue reading
An Overview of Secure Sockets Layer (SSL) Technology
SSL (Secure Sockets Layer) the most widely used and most powerful measure in security technology for creating an encrypted link between the Web Server web browsers. If the link is encrypted, they use https protocol. Secure receptacle Layer (SSL) and Transport Layer Security (TLS) is the protocol above TCP, which can protect user’s confidentiality when they sending data from a customer side to a web server; this is an important protocol due to the extension of Internet. In fact, it is a long way to make the SSL/TLS protocol fully. However there are still flaw and problems during the development of SSL/TLS, and we cannot deny that there maybe some other potential security hole in the latest version. sequential attack is fatal for both the user and the company in using these protocols to establish a safe channel to transfer information. This article will introduce three typical attacks: Cipher suite Continue reading
Bitcoin – Meaning, Transactions, Mining and Network Security
Bitcoin is a decentralized virtual cryptocurrency, launched in 2009 by an unidentified person known as Satoshi Nakamoto. It does not rely on any central services for managing the creation or flow of money. It relies on cryptographic algorithms in order to prevent abuse of the system. It is abbreviated as BTC and is powered by a peer-to-peer network in the public domain both in terms of issuing and valuation. Until Bitcoin €™s invention, online transactions always required a trusted third-party intermediary. For example, if a person A wanted to send $10 to B over the Internet, he would have had to depend on a third-party service like Paypal. Intermediaries like Paypal keep a ledger of balance of account holders. When A sends $10 to B, Paypal deducts this amount from A €™s account and credits it to B €™s account. The digital money could be spent more than once without Continue reading
Strategic Issues in Managing Technology
Due to increased competition and accelerated product development cycles, innovation and the management of technology is becoming crucial to corporate success. The importance of technology and innovation must be emphasized by people at the very top and reinforced by people throughout the corporation. Management has an obligation to not only encourage new product development, but also to develop a system to ensure that technology is being used most effectively with the consumer in mind. External Scanning: Corporations need to continually scan their external societal and task environments for new developments in technology that may have some application to their current or potential products, Stakeholders, especially customers, can be important participant in the new product development process. Technological Developments: Focusing one’s scanning efforts too closely on one’s own industry is dangerous. Most new developments that threaten existing business practices and technologies do not come from existing competitors or even from Continue reading
