Answer Q1.
It is important to explore the traffic behaviour when designing the network because
• Behaviour of existing networks can be characterized by traffic behaviour.
• It is useful in selecting the technologies
• Network performance is quantified through it
• It imputes the usage of network to its users and applications.
During network upgrade or building a new network if designer fails to understand the traffic behaviour, following problems can emerge later in network.
• Traffic load could increase if designer is not fully aware of the traffic behaviour of network.
• Go slow or decrease in performance of system.
• Designer may fail to select the appropriate technologies for the network, which fails to meet customer requirements or

Distributed computing
Distributed systems are studied in this field of computer science. A distributed system is a system in which problem is divided into many tasks, each of the problem is solved by communication and coordination of network computers by passing messages
Characteristics of distributed systems are
1. Component concurrency.
2. Independent failure of components.
Applications,
1. telecommunication networks.
2. peer-to-peer network and world wide web.
3. computer networks like interne.
4. wireless sensor networks, routing algorithms.
5. virtual reality communities and massively multiplayer online games.
6. cellular and telephone networks.
7. distributed database and distributed database management system network application.
Distributed database management system.
It is a network of two or more than two oracle databases that reside on one or more than one machine. Consider a distributed system that connects three databases as an example, these are mfg, hq and sales. An application has ability to modify the data in several databases within a single distributed environment.
For example, a query from a manufacturing client on local database can recover joined data from the Department table on the remote HQ database and the products table on the local database.
The location and platform of the database are usually transparent for a client application. In the distributed system, you can create a synonym for remote objects so that users can access
Whether you’re stuck on the 405 freeway during rush hour, on the 15 freeway heading back from a long-weekend vacation, or driving through the busy streets of Hollywood, traffic on the highways and streets of Los Angeles can often be a hassle. In Dagoberto Gilb’s short story Love in L.A., first published in 1986, the troubles of traffic are experienced first hand by our main character Jake. Jake is a common fellow with a steady occupation who is merely trying to make his way to work through the busy streets of Hollywood. As he is working his way through the piled traffic, not paying complete attention to the road in front of him, Jake crashes into the back of a Toyota. In the midst of exchanging information with the driver of the Toyota,
A successful IT system is something that is composed of several different functional components to make it a whole. It takes each component to efficiently work so that the entire system runs smoothly. When one or more parts of the system are not properly working it can affect the entire IT system as a whole and render it completely vulnerable to people with malicious intentions. In this paper I will discuss the role of each component in it and shed some light as to why each is needed.
a. Mainframes or minicomputer system: In a mainframe or minicomputer system the resources to be taken care of are :
Late 20th century Los Angeles, California was a bustling, diverse, and segregated city. Both El Norte (1983) and Falling Down (1993) depict Los Angeles in revealing ways. Falling Down in particular has many shots of the city itself; in fact, the first scene in the film takes place in a classic LA traffic jam on the highway. It shows cars lined up and not moving on the highway as far as the eye can see, with construction going on around them. It is also very hot in LA. The people are sweating, it’s sunny outside, bugs are flying around, and there are palm trees around the highway. Similarly, one of the last shots in El Norte shows a busy highway with the LA skyline in the background. That shot with the skyscrapers, cars driving quickly by, and palm trees is one of the most iconic images of LA in either film.
The distributed system defines, how the processes to communicate and gives data access for end client to the APIs which are used to manage the distributed data. Every distributed system have identified by communication protocol and address information.
For instance if a database software programmer wants to make changes and edit the data in different Databases then he should open all the Databases which he wants to make changes and do the required alterations and then again has to log out from all the Database explorers after work is completed. Multiple database management system application, can be used by the same person who is interested to make changes at once in all the different Databases.
Monitored the network congestion in order to achieve the optimal performance out of a network infrastructure.
Understand why a certain link or network is not functioning as per performance specifications and will be able to successfully resolve them.
Some of them are to careful initialization of network parameters, early stopping etc. But most effective solution was to
In a distributed database system, all the databases or the storage devices are not connected to a single common processing unit like CPU. The various data may be stored at different physical locations in multiple computers that are located in the same physical location; or they may be inter-connected over a network. In other words, distributed database system consists of various data locations but they do not share any physical components.
First off to start the assignment only requires writing about four different types of failures that can happen on a distributed system, however there are many more than just four types of failures that can happen and they are all important to learn about if you are going to work with a distributed system so that you know how to deal with and handle each one of them.
In local area networks (LANs) computers compete for the use of telecommunication paths all the time. If too many computers are trying to send data
This is because, to implement any change to the network policies, the network engineers have to reconfigure each device individually to ensure a consistent set of access, security and QoS parameters.
Formulating a network diagram, likewise alluded to as a logic diagram, in order to comprehend and envision how each task will continue is an extraordinary path to begin. It is a basic idea within project management planning that is effectively utilising as a part of application, commonly used as a part of assembling commercial enterprises, and also to outline and comprehend work processes are what service industries requires. It distinctively shows the rational rules for influencing tasks. (Holland, 2014) The development of the network diagram by incorporating the project team acquires an agreement of comprehension of how the undertaking ought to be accomplished. Nonetheless, giving a discussion to testing acknowledged
This being the case it is important for the engineer to consider the application to which the design will be used as well as how and to what extent it will be handled. In the instance that risks and dangers are present they must immediately be brought to the attention of the consumer, and if effected as a whole, the public.
