WGU C182 Objective Assessment Study Set 2023 with complete solution

WGU C182 Objective Assessment 2023 First users were the engineers who built and programmed computers, then employees who had received specialized training were users, and now today, anyone and everyone can be a user. - Evolution of Users Sends files over the network at the request of clients. Responds over LAN, within one location/site. Support both application software and data files. - FILE SERVER Turns a user-friendly domain name, like G, 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 IPOS - The INPUT Processing, OUTPUT, STORAGE Cycle Processed data - Raw data that is organized and structured for usefulness. output data - An information processing activity that retrieves, formats, and distributes data to users. Storage - Processed information is stored for permanent record. Computer System - A collection of components that work together to meet the needs of the user; typically : CATEGORIZED AS EITHER HARDWARE, SOFTWARE, NETWORKS AND USERS Hardware - Physical components of a computer system which include the system unit and its components and peripheral devices; TANGIBLE ASPECTS OF THE COMPUTER Network - A collection of computers and resources CONNECTED by various media so that they can COMMUNICATE WITH EACH OTHER. Software Categories - Systems Software and Applications Software IP Protocol - RULES provided by WHICH NETWORKS communicate with each other. computer memory - STORES the programs BEING EXECUTED and the data they are using. system clock - Controls THE SPEED at which instructions are processed RAM - Stands for Random Access Memory. It temporarily stores data before it is processed and sent to your screen or printer. IT IS VOLATILE (means data or information stored disappears when the computer is turned off or loses power). Second generation computers - Transistor components, magnetic core memory, smaller size, easier to program, disk drives and drums, called mainframe computers Third generation computers - Silicon chips (known as ICs - integrated circuits), reduced cost, called mini computers, networks introduced via dumb terminals low-level language - Written for a specific machine by the engineers who built and ran the computers; no need for OS since only one program could run at a time Assembly Language - Easier than machine but still required detailed, precise LOW LEVEL instructions Language Translator Programs - Function is to TRANSLATE ONE LANGUAGE TO ANOTHER; take source code and convert it to another form; source code by itself cannot be read by a computer
