Download PresentationIntroduction Molecular nanotechnology or Nanotechnology is the name given to a specific sort of manufacturing technology to build things from the atom up, and to rearrange matter with atomic precision. In other words, we can say that nanotechnology is a three dimensional structural control of material and devices at molecular level. The nanoscale structures can be prepared, characterized, manipulated, and even visualized with tools. “Nanotechnology is a tool-driven field."...

Download Presentation This paper compares and contrasts two technologies for delivering broadband wireless Internet access services: "3G" vs. "WiFi". 3G refers to the collection of third generation cellular technologies that are designed to allow mobile cellular operators to offer integrated data and voice services over cellular networks. WIFI refers to the 802.11b wireless Ethernet standard that was designed to support wireless LANs. ...

Download PresentationIntroduction : - The name, General Packet Radio Service (GPRS) doesn't convey much information to the non-technical user. Describing it as providing a direct link into the Internet from a GSM phone, is much clearer. GPRS is to mobile networks what ADSL (Asymmetric Digital Subscriber Line) is to fixed telephone networks - the favoured solution for providing fast and inexpensive Internet links. GPRS will undoubtedly speed up a handset's Internet connection - but it remains...

Download Presentation Network bandwidth is also increasing concurrently with the CPU speeds. When in 1980s 10Mbs Ethernet was considered fast, we now have 100 Mbs Ethernet. The bandwidth is approaching the speed on 1 billion bits per second (1 Gbs), much due to the research in the field of fiber optic signalling. The three main fields data communications, telecommunication and computing are undergoing a period of transition. The field...

Download PresentationWhat is Bluetooth? What is it - a technology, a standard, an initiative, or a product? Bluetooth wireless technology is a de facto standard, as well as a specification for small form factor, low-cost, short range radio links between mobile PCs, mobile phones and other portable devices. The Bluetooth Special Interest Group is an industry group consisting of leaders in the telecommunications, computing, and networking industries that are driving development of the technology...

Download Presentation Internet technologies, through intranet and extranet applications, have proven themselves to be efficient and effective in streamlining existing processes from supply chain management to manufacturing logistics, from marketing to customer asset management, and by creating new value chains and businesses. Nevertheless, these changes and benefits signal only an evolutionary shift in the way we do business....

Download Presentation Many organizations utilize traditional wire-based networking technologies to establish connections among computers. These technologies fall into the following three main categories namely LAN, MAN & WAN. These traditional networking technologies offer tremendous capabilities from an office, hotel room, or home. Activities such as communicating via e-mail with someone located in a faraway town or conveniently accessing...

Global Mobile Satelite System To make a satellite phone call today from a location that does not offer terrestrial wire line or wireless coverage requires the use of a large, costly terminal, and entails very high per minute charges. Further, the quality of service is relatively poor because of annoying echoes, large transmission delays, over talk associated with satellite communications using geostationary satellites. There is a trend for mobile...

BiometricsBio-metrics is modern security system. It uses a person’s biological features to give access rights. The biological features like finger print, voice print, iris pattern, face print, signature(dynamic), retina, hand geometry, ear form , DNA, odor, keyboard stroke, finger geometry, vein structure of back of hand etc. are used. So, in this any unauthorized person cannot trap the information or assets. Today, to prevent illegal operations this technique is widely used. It is a user-friendly...

Dna Computers DNA Computer can store billions of times more information then your PC hard drive and solve complex problems in a less time. We know that computer chip manufacturers are racing to make the next microprocessor that will more faster. Microprocessors made of silicon will eventually reach their limits of speed and miniaturization. Chips makers need a new material to produce faster computing speeds. To understand DNA computing lets first...

Internet Protocol Version 6The paper discusses on the up coming trends and the technologies used in the Internet World. It will explore the topic on IPV6 i.e. Internet Protocol Version 6. We say Internet Protocol Version 6 but what is this Protocol stuff; get familiarized with what is Protocols first and then we start with the in-depth study of IPV6. Like its previous versions IPV6 is all set to make waves in the Internet World. Here we will see what IPV6 is, why IPV6 is selected and why we...
