Illegal File Sharing Controversy The controversial act of illegal file sharing copyrighted content through the use of the internet has questioned computer ethics. There have been a number of cases involving this supposed illegal act but I will discuss a couple of these cases in detail and explain their significance to the ethical standards of computing machinery. In addition, I will provide statistical data that favors my position and discuss the flaws of security behind the use of peer-to-peer...
Satellite Digital Radio concept involves broadcasting of radio data and services through a satellite link to be received by receivers that can be both fixed or mobile. The aim is to provide high quality audio transmission and seamless usage for this the European Telecommunications Standard Institute (ETSI) has developed a guide and in its standards has given outlines of a structure that could be followed to ensure high quality of service and implementation of radio services. The ETSI...
This paper describes an Internet security threat that could endanger the privacy of World Wide Web users and the integrity of their data. The attacker resort to social engineering to fraudulently acquire sensitive information, such as credit card details, passwords, and social security numbers. The targeted victim is given the impression that the attacker is a trustworthy person or business, and the victim confidently hands over the requested information. In this article we will look at the...
I met some with simulation of networks designing scenarios according to my time schedule. Again my designing scenarios were getting long time to simulation. So I reduced some application traffic. When I was designing more network scenarios, OPNET drive space was full. Then I sent a mail to my supervisor to increase that space. Then I more enough space regards my supervisor.Key word during next periodNext work is focusing; the simulation of designing networks scenarios and gets the statistical...
Ans. The satellite communication is the one by which we can cover the maximum range, but still there some major problems which make satellite communication unfit for day to day use. These are as under: Cost: All aspects of satellite systems are expensive by comparison to terrestrial systems. To survive the environment of space all components need to be of very high grade. Additionally all systems need to have significant redundancy due to the inability to effect repairs after launch. As well as...
According to Hunton(1998),a computer virus is a programming code which infiltrates a Computer system .Once inside, it waits to be executed and then performs the work that it was programmed to do. That could include duplicating, erasing data from the hard disk and producing undesirable side-affects. Computer virus are similar to Parasites, it exploits other cells to stay alive. One of the significant properties of a Computer virus is to spread from the host system to other system in a very...
Desktop user interface design has evolved on the basis that users are stationary (i.e. - sitting at a desk) and can normally devote most of their visual and physical resource to the application with which they are interacting. In contrast, users of mobile and wearable devices are typically in motion whilst using their device which means that they cannot devote all or any of their visual resource to interaction with the mobile application - it must remain with the primary task, often for safety...
The increased use of mobile computing and availability of networked applications has resulted in demand for "sandboxes", which provide environments that impose irrevocable restrictions on resource usage [7]. There are several approaches for creating these environments, which include kernel modification and using operating system provided performance counters etc… Sandbox approach has become one of most efficient way of creating secure, private environments within shared environment....
Considered one of the first security mechanisms introduced by manufactures Wired Equivalent Privacy (WEP), it's considered as a part of 802.11 standard for encrypting WLAN traffic. Wired equivalent privacy is a shared-secret key encryption system used to encrypt packets transmitted between a station and an AP. The WEP algorithm is intended to protect wireless communication from eavesdropping. A secondary function of WEP is to prevent unauthorized access to a wireless network. WEP encrypts the...
There are total 15 or 1 billion people of the proportion which are identified as disability among the total population. Compared to the year of 2008, the total proportion of the disability has increase significantly which from 400 million to 1 billion [2]. The disabled people can be identifying as many types of disabilities. Mobile and physical impairments, spinal cord disability, other medical issues and etc are the example types of the disability. Most of them are facing difficulty when using...
