Computer Networks Does anyone really know what networking is? “In the world of computers‚ networking is the practice of linking two or more computing devices together for the purpose of sharing data” (Networking Fundamentals). Now this is a great explanation but does this really help us understand? Networking has grown over many years. Where did networking come from? Lets go back to the beginning and find out how far we have come. Network research can be traced back to around the 1960’s.

Computers are not only needed to do homework‚ but they have also become essential tools for work‚ social life‚ and everyday tasks. With the help of technology‚ computers now allow us to share information (emails‚ documents‚ etc.)‚ resources and software applications in just seconds. This sharing often occurs through

Software Metric Software metric is a measure of some property of a piece of software or its specifications. Since quantitative measurements are essential in all sciences‚ there is a continuous effort by computer science practitioners and theoreticians to bring similar approaches to software development. The goal is obtaining objective‚ reproducible and quantifiable measurements‚ which may have numerous valuable applications in schedule and budget planning‚ cost estimation‚ quality assurance testing

Windows end-users and Internet routing technology have both become more frequent targets of intruder activity. The control mechanisms for DDoS attack networks are changing to make greater use of Internet Relay Chat (IRC) technology. The impacts of DoS attacks are causing greater collateral damage‚ and widespread automated propagation itself has become a vehicle for causing denial of service. While DoS

External entities are sources and destinations of the system’s inputs and outputs. 1.b) ENTITY RELATIONSHIP DIAGRAM Entity–relationship model (ER model) in software engineering is an abstract way to describe a database. This article refers to the techniques proposed in Peter Chen’s 1976 paper.An ER model is an abstract way to describe a database. There are three basic elements in ER models: Entities are

states that “Errors are most frequent during the requirements and design activities and are the more expensive the later they are removed”. Generally errors made while collecting the requirements and developing a project. Questions arise when analysing those errors‚ these questions leads to put in an extra work in checking each and every phases of the project. Most errors occur in early phase of the project (i.e.) the requirements and design errors. If the developer does not know the actual domain then
