Document Summary
Wireless lan (wlan): a local area network that uses radio signals to transmit and receive data over distances of a few hundred feet. Wireless man (wman): a metropolitan area network that uses radio signals to transmit and receive data. Legacy system: an old system that is fast approaching or beyond the end of its useful life within an organization. Conversion: process of transferring information from legacy system to new system. Software customization: modifies software to meet specific user or business requirements. Off-the-shelf application software: supports general business processes and does not require any specific software customization to meet the organizations needs. Systems development life cycle (sdlc): overall process for developing information systems, from planning and analysis through implementation and maintenance. Planning -> analysis -> design -> development -> testing -> implementation -> maintenance. Agile methodology: (mvp) aims for customer satisfaction through early and continuous delivery of useful software components developed by an iterative process using the bare minimum requirements.
