Support both application software and data files. ✔✔FILE SERVER Turns a user-friendly domain name, like Google.com, into an Internet Protocol (IP) address like ((( 70.42.251.42 ))) that computers use to identify each other on the network. ✔✔Domain Name Server (DNS) Uses TWO KEYS a public and private key for performing encryption and decryption ✔✔Public Key Encryption PROVING you are who you say you are which can be done by: what you know, what you have! ✔✔Authentication TIER WHERE THE USER interface for the system is developed; SHIELDS THE USER from the underlying logic of the systems as well as the underlying data structures ✔✔Presentation Tier SYSTEMS DEPLOYMENT Steps 1. System Conversion 2. Final Documentation 3. End User Training ✔✔System Deployment CONNECTS MULTIPLES networks together; can be used to directly connect computers to a network; will relay messages to computers with APPROPRIATE IP ADDRESS ✔✔ROUTER Requires that data is KEPT secure so that they are not accidentally provided or obtained by unauthorized users ✔✔Confidentiality Protecting EVERY LAYER that SURROUNDS ((( DATA ))) ✔✔Defense in Depth Can take on DIFFERENT FORMS depending on the complexity of the application; in certain instances, it is AN ACTUAL OBJECT that is an ACTUAL IMPLEMENTATION of the application ✔✔THE MODEL Creates a subset of the data by reducing the data from multiple dimensions to one dimension ✔✔Slicing Data The technology used in creating, maintaining, and making information accessible. ✔✔Information Technology In charge of all aspects of the COMPUTER NETWORKS ✔✔Network Administrator Focuses on the design, development, and support of DATABASE MANAGEMENT systems (DBMSs). ✔✔Database Administrator Installs, configures, maintains, secures, and troubleshoots web severs ✔✔Web Administrator Processed data. ✔✔Information INFORMATION THAT HAS BEEN PUT TO USE information placed into a context. Refined information such that the user of the knowledge is able to call forth only relevant portions of information when needed. ✔✔Knowledge in DIKW Provides a social setting to knowledge; AN UNDERSTANDING OF THE ((( WHY ))) Can only come by having BOTH KNOWLEDGE and EXPERIENCE ✔✔WISDOM The INPUT Processing, OUTPUT, STORAGE Cycle ✔✔I.P.O.S. Raw data is organized or structured for usefulness. ✔✔PROCESSED DATA Information is output so user can see results. ✔✔OUTPUT DATA Processed information is stored for permanent record. ✔✔STORAGE A collection of components that work together to meet the needs of the user; typically : CATEGORIZED AS EITHER HARDWARE, SOFTWARE, NETWORKS AND USERS ✔✔COMPUTER SYSTEM Physical components of a computer system which include the system unit and its components and peripheral devices; TANGIBLE ASPECTS OF THE COMPUTER ✔✔HARDWARE A collection of computers and resources CONNECTED by various media so that they can COMMUNICATE WITH EACH OTHER. ✔✔NETWORK Systems Software and Applications Software ✔✔SOFTWARE CATEGORIES RULES provided by WHICH NETWORKS communicate with each other ✔✔IP PROTOCOL STORES the programs BEING EXECUTED and the data they are using. ✔✔COMPUTER MEMORY Controls THE SPEED at which instructions are processed. ✔✔SYSTEM CLOCK Stands for Random Access Memory.
