attack. Disaster recovery plans focus primarily on the technical issues involved in keeping systems up and running, such as which files to back up and the maintenance of backup computer systems or disaster recovery services. Business continuity planning focuses on how the company can restore business operations after a disaster strikes. The business continuity plan identifies critical business processes and determines action plans for handling mission-critical functions if systems go down. Identify and describe the security problems posed by cloud computing. Accountability and responsibility for protection of sensitive data reside with the company owning that data even though it’s stored offsite. The company needs to make sure its data are protected at a level that meets corporate requirements. The company should stipulate to the cloud provider how its data are stored and processed in specific jurisdictions according to the privacy rules of those jurisdictions. The company needs to verify with the cloud provider how its corporate data are segregated from data belonging to other companies and ask for proof that encryption mechanisms are sound. The company needs to verify how the cloud provider will respond if a disaster strikes. Will the cloud provider be able to completely restore the company’s data and how long will that take? Will the cloud provider submit to external audits and security certifications? Describe measures for improving software quality and reliability. Using software metrics and rigorous software testing are two measure for improving software quality and reliability. Software metrics are objective assessments of the system in the form of quantified measurements. Metrics allow a information systems department and end users to jointly measure the performance of a system and identify problems as they occur. Metrics must be carefully designed, formal, objective, and used consistently. Examples of software metrics include: - Number of transactions that can be processed in a specified unit of time - Online response time - Number of known bugs per hundred lines of program code Early, regular, and thorough testing will contribute significantly to system quality. Testing can prove the correctness of work but also uncover errors that always exist in software. Testing can be accomplished through the use of: - Walkthroughs: a review of a specification or design document by a small group of people - Coding walkthroughs: once developers start writing software, these can be used to review program code. - Debugging: when errors are discovered, the source is found and eliminated

Name and describe the principal network topologies. The principal network topologies include: Star topology : all devices on the network connect to a single hub and all network traffic flows through the hub. Bus topology : one station transmits signals, which travel in both directions along a single transmission segment. All of the signals are broadcast in both directions to the entire network, with special software to identify which components receive each message. Ring topology : connects network components in a closed loop. Messages pass from computer to computer in only one direction around the loop and only one station at a time may transmit. 3. How do the Internet and Internet technology work, and how do they support communication and e-business? Define the Internet, describe how it works and explain how it provides business value. The Internet is a vast network of computers that connects millions of people all over the world. The Internet uses the client/server model of computing and the TCP/IP network reference model. Every computer on the Internet is assigned a unique numeric IP address. No one owns the Internet, and it has no formal management organization. However, worldwide Internet policies are established by organizations and government bodies, such as the Internet Architecture Board and the World Wide Web Consortium. The Internet must also conform to the laws of the sovereign nation-states in which it operates, as well as the technical infrastructure that exist within the nation-state. The Internet enables employees to gain remote access to the company’s internal systems through its Web site. They are able to better service customers and suppliers, improve operational efficiency, increase productivity, lower operational costs, have a broader market base, and reach more individual customers on a global scale by establishing a Web presence. The cost of e-mail and other Internet services tend to be far lower than equivalent voice, postal, or over night delivery costs, making the Internet a very inexpensive communication medium. It is also a very fast method of communication, with messages arriving anywhere in the world in a matter of seconds or minutes. Explain how the Domain Name System (DNS) and IP addressing system work. A domain name is the English-like name that corresponds to the unique 32-bit numeric IP address for each computer connected to the Internet. The Domain Name System (DNS) converts IP addresses to domain names so that users only need to specify a domain name to access a computer on the Internet instead of typing the numeric IP address. DNS servers maintain a database containing IP addresses mapped to their corresponding domain names.
