RANCHI: In the era of the new technologies where every one is indulging in developing new technologies how Indians can stay behind. India has also come up with its new invention which is neither smartphones nor any other gadgets but with a extraordinary invention in the form of world’s smallest antenna. Indian researchers claimed that they invented the world’s smallest super compact ultra-wideband (UWB) planar antenna. This special smallest antenna can find application in homes and the military among other domains. [Read more…]
Domain Name System
Introduction to Domain Name
You may have heard this term, but many of you do not know it properly. Let us start studying this topic. Domain name is an identification string that defines a realm of administrative autonomy, authority, or control on the Internet. In simple words, it is the name of the website. It is difficult for a user to memorize the numeric values (IP) for accessing a website like 174.12.14.10 so we give it an English name which is easy to memorize like catchupdates.com or google.com. Here both catchupdates.com and google.com are domain names. [Read more…]
What Are Honeypots? Various Types Of HoneyPots
Honeypots are an information system resource whose value lies in the unauthorized or illicit use of that resources.
In other words, “A server that is configured to detect an intruder by mirroring a real production system. It appears as an ordinary server doing work, but all the data and transactions are phony. Located either in or outside the firewall, these are used to learn about an intruder’s techniques as well as determine vulnerabilities in the real system.” [Read more…]
Tele-Immersion
Tele-immersion is designed and developed to allow users in geographically distributed sites to collaborate in real-time in a shared simulated environment. This enterprise has engaged the skills of researchers in a variety of disciplines, including computer vision, graphics and network communications.
Tele-Immersion (TI) is defined as the integration of audio and video conferencing, via image-based modeling, with collaborative virtual reality (CVR) in the context of data-mining & significant computation. [Read more…]
What is 3 Dimensional Printing?
3 Dimensional printing is the process of making three-dimensional solid objects from a digital model. 3 Dimensional Printing is a process under development at MIT for the rapid and flexible production of prototype parts, end-use parts, and tools directly from a CAD model. 3D printing is achieved using additive processes, where an object is created by laying down successive layers of material. 3D printing is different from traditional machining techniques as they mostly rely on the removal of material by drilling, cutting, etc.
What is Thin Client Computing?
This concept is widely accepted on a very large scale. In a traditional or fat-client environment, applications are stored locally, and data is stored centrally. Whenever we have to open a file, the entire file is transferred to the local PC, with the results being saved back across the LAN/WAN to the central storage area. Server/client architecture handle this process slightly differently, but processing still takes place at the local PC. [Read more…]
Cluster computing
During the past decade, many different computer systems supporting high-performance computing have emerged. Cluster computing is a form of computing in which a group of computers is linked together so that they can act like a single entity. Clusters are usually deployed to improve performance and availability over that of a single computer while typically [Read more…]
What is Ethical hacking? What are different Types of Hackers
Before talking about Ethical Hacking, let’s discuss what hacking is. Hacking can be defined as the practice of modifying the features of a system, in order to accomplish a goal outside of the creator’s original purpose. In general words, hacking is the unauthorized use of computer and network resources. Some other specialists refer it to the hobby or profession of working with computers. [Read more…]
