Total Cost of Ownership (TCO) - Helps establish feasibility. Platform as a Service (PaaS) - service provider provides server space, the server, virtualization, operating system, database, and development environment in a platform that can be used for application development. An example would be Amazon Web Services. Infrastructure as a Service (IaaS) - A service provider provides a cloud fabric, or pooled services, including server space, servers, storage, and all other aspects of the computing platform, with the exception of the operating system and applications, which the client organization would install and manage. Analytics as a Service (AaaS) - A cloud software service Software as a Service (SaaS) - Software licensed and hosted on centralized or distributed servers that belong to a service provider. Users access this software using a connection to the Internet and a web browser. Agile software development methodology - an operational method by which software developers iteratively gather requirements, plan, design, develop, test, and implement software. Information Technology Infrastructure Library (ITIL) - common set of best practices widely used by businesses to give guidance to companies on how to use IT as a tool for implementing change Pseudocode - an informal high-level description of the operating principle of a computer program or other algorithm. Used for human reading, rather than machine reading, and it can be used to translate into any programming language. Input - components include devices that provide input into the processing unit. These include peripherals, such as the keyboard, mouse, microphone (audio input), sensors, and document or visual scanners. Central Processing Unit (CPU) - the brain/microprocessor of the computer. Output - Components include internal storage devices or processes, as well as external peripherals such as monitor screens (visual output), speakers (audio output), and printers (physical output). system bus - connection between the CPU, memory, storage, expansion slots, and other motherboard components primary storage - flash memory chips, such as shown below, plugged into memory slots on the motherboard. Secondary storage - accessed only through a system's input/output bus and is generally several orders of magnitude slower than primary storage technologies Removable media, such as magnetic floppy disks, optical discs (CDs & DVDs), and USB flash drives Tertiary storage - consists of an automated robotic mechanism to mount and dismount magnetic tape or optical discs.
