In todays modern era responsibilities in network security is more complicated and plays an important role in scope from security controls management for a huge Method to prevent the unauthorised access with the help of password protection. So in particular every individual often has more than one role or various techniques .Here my entire concept is based on crypt-analysis method which is called cryptography. Symmetric encryption is a form of cryptosystem in which encryption and decryption are...
AJAX is shorthand for asynchronous javascript and XML. It is a group of interrelated web development techniques used on the client-side to create interactive web applications. With Ajax, web applications can retrieve data from the server asynchronously without prying with the display and actions of the existing page. The use of Ajax techniques has led to enhance in interactive and dynamic interfaces on web pages. Data are typically retrieved with the XMLHttpRequest object. Even though the...
Hardware and software are the main concerns that computer users put in consideration when buying or using computers. Many small businesses have failed because of the high costs of using different hardware and software. The concept that we are discussing in this report is called "Cloud Computing" which is a great solution to all hardware and software problems. Using Cloud Computing we will not need to update any software at all, in fact we will not even need to buy software anymore. As...
Eyes are the most effective means of communication. Humans share considerable information through their eyes. Internet and other digital technologies enhances the human experience of communication with others. One such thing is eye typing, which would be a tremendous technology for disabled persons. Locked- in syndrome (LIS) and cerebral palsy (CP) are severe disabilities that lead to the complete loss of control over voluntary muscles making the individual paralyzed and mute. The above...
Last year, with the expansion business of school, head of Computing department realized that manual process of Computing department no longer suitable, slow performance and error-prone rate increasing. Thus discuss with Information Technology System Department (ITSD) and confirmed a computerization era should come to cope with the shortcoming. There is a small village school, need to create a computer classroom, and students range in age from 5 to 11 years and a classroom about 21 students, has...
Video conferencing is the live chat between two or more group of people from any multimedia device. It is used to exchange the ideas and voice conversation of two groups of maybe a community. In other words ,we can do almost everything in a video conference with any distance I,e the people maybe living in different countries or city. Video conferencing may involve scanned images such as photos,3D images,and charts). High quality audio can me made in the video conferencing application with the...
Abstract- Sequences consensus problems are especially important in studying molecular evolution, protein structures, and drug target design. In this paper, we work on two of these problems, namely closest string problem and farthest string problem. These problems are NP-hard, and none of exact algorithms already proposed to solve them is in polynomial time. Many non-exact algorithms have been proposed which try to obtain 'good' solutions in acceptable time for these problems. In this paper, a...
Computed tomography (CT) is a radio graphic inspection method that generates a 3-D image of the inside of an object from a large series of 2-D images taken on a cross-sectional plane of the same object. In most clinical conditions, CT has been necessary in adjunction to conventional radiography. Generally speaking, conventional radiographs depict a 3-D object as a 2-D image, produced by an X-ray tube, which rotates around the body of the stationary patient. of Hounsfield scales that represents...
PHP stands for PHP - Hypertext Preprocessor. It is a scripting language used for developing dynamic Web pages. It is embedded within HTML codes. It is an open source Web page scripting language. PHP code is executed on the server and as a result the client cannot view the code. In this session, we will learn about the history how to write a simple PHP script, how to generate HTTP headers using PHP and how to pass variables via URL. PHP is an advanced product of PHP/FI. Rasmus Lerdorf created...
Secure Shell is a very highly successful protocol used for interactive shells as well as transport layer mechanisms which uses strong cryptographic tools to establish network connections with "privacy|", "integrity", and "mutual authentication"[1]. The original SSH 1 protocol was very renown, dispite being somewhat ad hoc; it had number of limitations. The current protocol version, SSH 2, is much better, but was slow to take off due to some...
