Terms in this set (70)MIS Infrastructure Includes the plans for how a firm will build, deploy, use, and share its data, processes, and MIS assets. Hardware Consists of the physical devices associated with a computer system Software The set of instructions the hardware executes to carry out specific tasks. Network A communications system created by linking two or more devices and establishing a standard methodology in which they can communicate. Client A computer designed to request information from a server. Server A computer dedicated to providing information in response to requests. Information MIS infrastructure Identifies where and how important information, such as customer records, is maintained and secured. Agile MIS infrastructure Includes the hardware, software, and telecommunications equipment that, when combined, provides the underlying foundation to support the organization's needs. Sustainable MIS infrastructure Identifies ways that a company can grow in terms of computing resources while simultaneously becoming less dependent on hardware and energy consumption. Backup An exact copy of a system's information. Recovery The ability to get a system up and running in the event of a system crash or failure that includes restoring the information backup. Fault tolerance The ability for a system to respond to unexpected failures or system crashes as the backup system immediately and automatically takes over with no loss of service. Failover A specific type of fault tolerance that occurs when a redundant storage server offers an exact replica of the real-time data. Failback Occurs when the primary machine recovers and resumes operations, taking over from the secondary server. Disaster recovery plan A detailed process for recovering information or a system in the event of a catastrophic disaster. Hot site A separate and fully equipped facility where the company can move immediately after a disaster and resume business. Cold site A separate facility that does not have any computer equipment but is a place where employees can move after a disaster. Warm site A separate facility with computer equipment that requires installation and configuration. Disaster recovery cost curve Charts (1) the cost to the company of the unavailability of information and technology and (2) the cost to the company of recovering from a disaster over time. Emergency A sudden, unexpected event requiring immediate action due to potential threat to health and safety, the environment, or property. Emergency preparedness Ensures a company is ready to respond to an emergency in an organized, timely, and effective manner. Business continuity planning (BCP) Details how a company recovers and restores critical business operations and systems after a disaster or extended disruption. Business impact analysis Identifies all critical business functions and the effect that a specific disaster may have upon them. Emergency notification service An infrastructure built for notifying people in the event of an emergency. Technology failure Occurs when the ability of a company to operate is impaired because of a hardware, software, or data outage. Incident management The process responsible for managing how incidents are identified and corrected. Technology recovery strategies Focus specifically on prioritizing the order for restoring hardware, software, and data across the organization that best meets business recovery requirements. Accessibility The varying levels that define what a user can access, view, or perform when operating a system. Administry access Unrestricted access to the entire system. Web accessibility People with disabilities, including visual, auditory, physical, speech, cognitive, and neurological disabilities, can use the web. Web accessibility initiative (WAI) Brings people together from industry, disability, organizations, government, and research labs from around the world to develop guidelines and resources to help make the web accessible to people with disabilities. Availability The time frames when the system is operational. Unavailable Not operating and cannot be used. High availability Occurs when a system is continuously operational at all times. Maintainability (flexibility) Refers to how quickly a system can transform to support environmental changes. Portability The ability of an application to operate on different devices or software platforms, such as different operating systems. Reliability (accuracy) Ensures a system is functioning correctly and providing accurate information. Vulnerability A system weakness that can be exploited by a threat. Scalability Describes how well a system can scale up, or adapt to the increased demands of growth. Performance Measures how quickly a system performs a process or a transaction. Capacity The maximum throughput a system can deliver; for example, the capacity of a hard drive represents its size or volume. Capacity planning Determines future environmental infrastructure requirements to ensure high-quality system performance. Usability The degree to which a system is easy to learn and efficient and satisfying to use. Serviceability How quickly a third party can change a system to ensure it meets user needs and the terms of any contracts, including agreed levels of reliability, maintainability, or availability. Moore's Law Refers to the computer chip performance per dollar doubles every 18 months. Sustainable (green) MIS Describes the production, management, use, and disposal of technology in a way that minimizes damage to the environment. Corporate social responsibility Companies' acknowledged responsibility to society. Ewaste Refers to discarded, obsolete, or broken electronic devices. Sustainable MIS disposal Refers to the safe disposal of MIS assets at the end of their life cycle. Energy consumption The amount of energy consumed by business processes and systems. Carbon emissions Carbon dioxide and carbon monoxide produced by business processes and systems. Grid computing A collection of computers, often geographically dispersed, that are coordinated to solve a common problem. Smart grid Delivers electricity using 2-way digital technology. Virtualization Creates multiple "virtual" machines on a single computing device. Data center A facility used to house management information systems and associated components, such as telecommunications and storage systems. Cloud computing A model for enabling ubiquitous, convenient, on-demand network access to a shared pool of configurable computing resources. Multi-tenancy In the cloud means that a single instance of a system serves multiple customers. Single-tenency Each customer or tenant must purchase and maintain an individual system. Cloud fabric The software that makes possible the benefits of cloud computing, such as multi-tenancy. Cloud fabric controller An individual who monitors and provisions cloud resources, similar to service administrator at an individual company. Utility computing Offers a pay-per-use revenue model similar to a metered service such as gas or electricity. Infrastructure as a service (IaaS) Delivers hardware networking capabilities, including the use of servers, networking, and storage, over the cloud using a pay-per-use revenue model. Dynamic scaling Which means the MIS infrastructure can be automatically scaled up or down based on needed requirements. Software as a Service (SaaS) Delivers applications over the cloud using a pay-per-use revenue model. Platform as a Service (PaaS) Supports the deployment of entire systems including hardware, networking, and applications using a pay-per-use revenue model. Public cloud Promotes massive, global, and industrywide applications offered to the general public. Private cloud Serves only one customer or organization and can be located on the customer's premises or off the customer's premises. Community cloud Serves a specific community with common business models, security requirements, and compliance considerations. Hybrid cloud Includes 2 or more private, public, or community clouds, but each cloud remains separate and is linked by technology that enables data and application portability. Cloud bursting When a company uses its own computing infrastructure for normal usage and accesses the cloud when it needs to scale for peak load requirements, ensuring a sudden spike in usage does not result in poor performance or system crashes.
