Use Cases are not inherently object-oriented. Why then is use case modelling so important in the Object-Oriented approach? Discuss. Most projects have failed due to the problem of clarity in requirements. Requirements serve as a key part of system development since it is an input to system development and “a system” is produced as the output. Therefore if the requirement stage is wrong‚ the whole system will be wrong. Hence‚ the project fails. Input output Requirements System

Logical vs. Physical Network Design The typical Top-Down approach to network design uses a systematic method to plan‚ design‚ and implement a new network. Generally‚ the Top-Down methodology involves analysis of the business requirements and goals‚ development of the logical design based on such goals‚ development of the physical design‚ and a phase for testing‚ optimizing‚ and documenting the network design. This paper focuses on the activities performed to create a logical design of a network

Logical vs. Physical Design of a Network In the world of network design‚ there are two common design types; the logical network design and the physical network design. A logical network design can be described as how the network will be structured‚ basically all logical aspects of the network. According to Webopedia‚ "the logical topology is the way that the signals act on the network media‚ or the way that the data passes through the network from one device to the next without regard to the

Physical vs. Logical Network Design Bob Jones NTC 410 Fernando Casafranca April 11‚ 2006 How is your network designed? This is a simple question. But‚ like many things in the information technology field‚ not a question with a simple answer. The definition of network design to a customer or user can be completely different than to an information technology professional. Even inside of the information technology field‚ there are several definitions of network design. We use the words Logical

Difference between Logical Design and Physical Design NTC 410 August 8‚ 2006 Understanding network topology can tell one a great deal about installing or expanding a network. At its basic level‚ the topology of a network refers to the way in which all its pieces have been connected. That is‚ it refers to the layout of the computers‚ printers‚ and other equipment hooked to the network (TechTarget 2006). Because cables connect computing resources together for a network‚ network ’s

Network Design: Logical and Physical Design In networking terminology‚ the term network topology refers to the entire structure of the network. There are two primary parts to the topology definition: the physical design‚ which is the actual layout of the wire (media)‚ and the logical design‚ which defines how the media is accessed by the hosts. The physical designs that are commonly used in networks are the Bus‚ Ring‚ Star‚ Extended Star‚ Hierarchical‚ and Mesh. A bus topology uses a single

BAYESIAN MODELLING OF DRIVER ERROR-CAUSED TRAFFIC ACCIDENTS IN METRO MANILA ABSRACT Filipinos have been known to be one of the most reckless drivers in the world. The Philippine government has been continuously reminding the public to drive safely and avoid reckless driving but the lack of discipline and complete disregard of traffic rules have led wasted time to destruction of both property and life. This study aims to aid in formulating traffic road policies in the busiest roads in the

force is the most logical answer to snuffing out terrorists. One of the largest problems with that course of action is the loss of human life associated with it. Unfortunately that may not be the largest problem associated with terrorism. The fact of the matter is that it will never go away. What we need to ask ourselves as a society is how we can combat terror. Some solutions could

MEMORY: “Memory is the process by which we encode‚ store and retrieve information”. PROCESS OF MEMORY: Memory is built on three basic processes i.e‚ • Encoding • Storage • Retrieval ENCODING: Encoding memory processes are seen as the processes which put information into the memory store. When information comes in from the external world it then goes through a process of transformation and is transformed into a code. Information from the external world can be encoded
