Chapter 4 1. What is the difference between an image editor and an illustration program? An image editor is a program used to modify or edit bitmap (raster) image files which use thousands of dots to represent an image. While an illustrator program is used to modify or edit vector images which use geometric shapes or objects to represent images. 2.Discuss Video and Audio software and how can they be used in professional production. In professional production video editing software can be used to enhance digital video footage, reorganize footage and add effects while audio editing software can be used to create and edit audio clips and can add audio effects like filters to tracks. 3. What are web authoring programs? Please elaborate. Web authoring programs are used to create sophisticated commercial websites without the knowledge of HTML. 4. What are the four steps to create an interactivity multimedia presentation? 1) Plan and analyze: determine the objective of the project 2) Design: create a storyboard for the project A Storyboard is a design tool used to record the intended overall logic, flow, and structure of a multimedia presentation 3) Create: use an authoring tool to create interactive multimedia presentations 4) Support: evaluate effectiveness, identify errors, and revise the project as needed 5. What is Artificial Intelligence? What main types are there? What are they used for? Artificial intelligence is a field in computer science that attempts to develop computers that can mimic or simulate human senses, thought processes and actions. The three main types are: 1) Virtual Reality: is used to navigate a virtual world. 2) Knowledge based (expert) systems: are used to provide assistance to users through the use of a database that contains facts, rules to relate these facts, and user input to formulate recommendations and decisions. 3) Robotics: which is the study of robots and is used in factories, manufacturing, home security, the military, and many other fields of human endeavor and there are three types: 1) Perception System Robots: imitate some of the human senses 2) Industrial Robots: perform tasks in factories, etc. 3) Mobile Robots: can move about and perform tasks 6. Think of a profession and discuss how concepts of this Chapter can help in this profession. Desktop publishers use computers to format and create publicationready material using specialized software to design page layouts, import text and manipulate graphics. Chapter 5 7. What is an operating system? Discuss operation system functions and features. An operating system is a collection of programs that handle many of the technical details related to using a computer. Some functions include: 1) Managing resources: This coordinates all the computers resources including memory, processing, storage and devices. 2) Providing user interface: this provides users with a graphical with graphical elements such as icons and windows. 3) Running applications: operating systems let you load and run application and most operating systems supports multitasking which is the ability to switch between programs stored in the memory. Features include: 1) Icons: graphic representations for a program or function. 2) Dialog Boxes: provides information or request input. 3) Menus: provides a list of options or commands. 8. Explain the differences and similarities between Windows, Mac OS, and Linux? 9. Discuss utilities. What are the five most essential utilities? What is a utility suite? Utilities are special programs used to making computing easier The five most essential utilities are: 1) Troubleshooting or diagnostic programs 2) Antivirus programs 3) Uninstall programs 4) Backup programs 5) File compression programs A utility suite is a group of several utility programs bundled for sale and the main advantage is the price 10. What is a device driver? Explain its role. Device drivers: are programs that work with the operating system to allow communication between device(s) and the rest of the physical system 11. Describe system software. What are the four types of system programs? System software is not a single program but is a collection of programs that handles hundreds of technical details The four types of system software are: 1) Operating system 2) Utilities 3) Device drivers 4) Language translators 12. What are the three basic operating system categories? Give Examples on each category. 1) embedded operating systems; like hand-held 2) Network operating systems; like linked computers 3) Stand-alone operating systems; like desktop Chapter 12 13. What are the two different views of data, and who should be concerned with each? 1) Physical view: actual format and location Specialized computer professionals are concerned with the physical view 2) Logical view: focuses on the meaning and content of the data End users and most computer professionals are concerned with this view 14. What are the six Components of Data? Explain an example of each. 15. Discuss four main advantages of using databases. 1) Sharing – in organizations, information in one department can readily be shared with others 2) Security – Users are given passwords or access only to the kind of information they need 3) Less data redundancy – decrease of unnecessary duplication of data (or data redundancy) when several departments use the same database of information 4)Increased data integrity - Reduced likelihood of inconsistent, incomplete, or inaccurate data – data lacking integrity 16. Using examples, explain the differences between Hierarchical; Network; and Relational databases. 17. Explain the different types of Databases in terms of functionalities. 1) Individual: Integrated file collection for one person usually under the person’s direct control 2) Company or shared: May be stored on a mainframe and managed by a database administrator and Provides access to users throughout a company and there are two types: 1) Common operational database: contains details about the operations of a company and data that describes the day-to-day operations of the organization 2) Common user database: contains selected information both from the common operational database and from outside private databases. 3) Distributed: Database is located in a place or places other than where users are located. Typically database servers on a client/server network provide the link between users and the distant data 4) Proprietary: Generally an enormous database developed by an organization to cover particular subjects and access is offered to the public or selected outside individuals for a fee 5) Web: Web databases incorporate special interface programs that create input forms, accept input, and send the data to the Web database
