Computer Science Questions - Essay Example Wilson argues that in order to determine the threat scale during computer forensic tactics preparation, one identifies the rate of spread of the malicious program (worm, virus). The other step involves determining the extent to which the malicious program has spread to other computer users and the damage that the program has inflicted on those users that have been affected (Wilson, 2002). I think that subnets are the most difficult part of IP addressing. This is because it is very hard to understand how to work with prefix length and subnet length. In addition, the determination of the host addresses and the prefix involves changing the address into binary by conducting logical (NOR and AND) operations on the subnet mask and address, before finally converting the figures into decimal points. According to White, IPv6 have a number of drawbacks such as the cost. In order to migrate to IPv6 protocols, businesses have to factor in time spent, additional personnel and monetary assets. A business has to buy new servers and basically new equipment for performing IPv6 functions that are very specific (White, 2012). Another factor is the complication of shifting to IPv6. The move entails involving all departments, which means that the day to day operations will be curtailed. In addition, all the departments have to be satisfied. Other factors include getting rid of the IPv4 inventory and handling issues relating to the legacy system. According to Mason et al., the factors to consider when deciding whether to implement a traditional zone or an integrated (AD) DNS zone include- the type of zones, database replication topologies and administrative supervision available (Mason, 2012). Halwagi argues that the main factors to consider when deciding which particular DCs host DNS include- hardware requirements, the place you will place DNS servers for traffic loads on the network, number of DNS servers and if you will exclusively use all DNS servers or a

Erp systems and integration - Essay Example This problem is overcome by ERP, which encapsulates the entire spectrum of business processes, including sales management, production management, accounting, human resources, maintenance management, quality management etc. ERP uses a single database in which information from different functional domains is stored. As a result, the information needs of different entities can be met from a single location. This integrated approach can, for instance, allow the production department located in one geographical area to send financial information to the head office and the marketing information of one location can be accessed by the production department at another location, so that the market patterns can be identified and the appropriate responses can be designed. Proper implementation of ERP ensures that the management has relevant and timely information at its disposal for effective decision-making. The effectiveness of the ERP system in business can be judged by the fact that in spite of its high cost of implementation, many organizations have adopted ERP systems. Business modeling is a precursor to business process reengineering, ERP implementation etc. A business model is a diagrammatic representation of different business systems and processes, and their interconnections and interdependencies. The purpose of business modeling is to provide a general overview of the operations of a business without going into the technical details of the processes and systems. It defines the activities performed and workflow structure in a broad manner. A good business model should be comprehensible, coherent and complete. It should define clearly the different systems and subsystems of a business system. A business model is developed on the basis of organization’s goals, objectives and strategic plans. Further, the model illustrates how
