Computer Engineering (& Problem Space) Focuses on design of hardware systems & software that makes them work (MOUNTAIN) Computer Science (& Problem Space) Addresses design & implementation of software with emphasis on developing effective ways to solve computing problems & created new ways to use computers (WORM) Software Engineering Focuses on development & maintenance of reliable & efficient software systems (OVAL) Information Systems Integrate IT solutions meant to meet organizational business goals (DRIP Information Technology Focuses on more technology supporting information systems in an organization rather than information residing on the systems of being communicated with them (THUMB ON PAPER) Data Pyramid It is a concept that visualizes the data-information-knowledge-wisdom hierarchy. Information A collection of data from a variety of sources. Data is continually aggregating and is not useful until it has been processed and is presented in a usable form. Can be unstructured or structured, and the key term associated with it is meaning Data Includes raw facts or observations. Knowledge It is a dynamic combination of experience, values, and contextual information. The key term associated with knowledge is "context" Wisdom it is knowing the right thing to do. Connectedness Wisdom is essentially "the path to connected understanding" when interpreting data. It is that human element leveraging an intelligent technology component when attempting to make fact-based decisions. Smart Data/Big Data Trusted source for business decisions, connections we may not imagined existed Structured Data Coded in a way that makes it easy to convert into a form usable for analysis. E.g. first name, last name, email, phone # Unstructured Data More complex & stored in a format that is not easy decoded. E.g. data stored in video/text format Information Systems Collections of data and information used to support decision-making in organizations Data Architectire Infrastructure used to manage data 3 Core Variations of Cloud-Based Systems IaaS, PaaS, SaaS Infrastructure as a Service (IaaS) Provides access in virtualized environment & computing resources are composed of virtual hardware (client responsible) Platform as a Service (PaaS) Customers have access to a platform that supports the development & management of web applications (cloud service provider responsible) Software as a Service (SaaS) Software is licensed to customers with subscriptions & central hosting. E.g. Microsoft Office 365 Analyzing Business Processes Collecting data from multiple platforms & portals, integrating for better overall view 3 Steps for Transforming Institutional Knowledge into Implementing Data Solutions Capturing, Analyzing, Using Types of Bad Data Duplicate data, conflicting data, incomplete data, invalid data, unsynchronized data IPOS (Input-Process-Output-Storage) The IPOS model explains what computer systems are used for. They take input, process it, and provide an output while using storage to keep intermediate and final results of the transformation of data. Individual hardware components support the function of computer systems. Middleware Allows software & hardware to communicate 3 Major Hardware Components CPU, storage, and peripheral devices CPU (Central Processing Unit) Supports data processing, electronic circuit responsible for executing computer program introductions. What is the term of the speed of processor processing information? Gigahertz Computer Memory Stores ephemeral programs and data in use temporarily for quick access, hardware in memory slots of motherboard, RAM Graphics Processor Unit Processes huge batches of graphic data, important for 3D rendering Hard Drive Storage device that stores digitally encoded data on rapidly rotating rigid disks with magnetic surfaces. The device is either permanently installed within the computer case or can be portable Power Supply Unit (PSU) Provides power to the internal components of the computer Peripheral Devices It supports the input and output operations of the system. Three parts of CPU ALU (Arithmetic Logic Unit), Control Unit, and Processor Register Arithmetic Logic Unit (ALU) It contains circuitry that performs on data. Such as addition and subtraction Control Unit It contains circuitry coordinating the machine's activities Processor Register It contains data storage cells (registers) Registers They serve as temporary holding places for data being manipulated by the CPU. It holds the inputs to the ALU and stores the results.
