Here are the answers to five questions from the exam paper: Q1: Define the following terms: (i) Graphics: Visual images or designs on a surface, such as a wall, canvas, screen, or paper, to inform, illustrate, or entertain.* (ii) Computer Graphics: The art of drawing pictures, lines, charts, etc., using a computer with the aid of programming. It involves creating and manipulating images using computational methods.* (iii) Application packages: A group of programs designed for end-users to perform specific tasks or functions, such as word processing, spreadsheets, or presentations. Examples include Microsoft Office Suite.* (iv) Desktop publishing (DTP): The creation of documents using page layout software on a personal computer. It is used to produce high-quality printed materials like brochures, magazines, and books.* (v) Computer Aided Design (CAD): The use of computer systems to assist in the creation, modification, analysis, or optimization of a design. CAD software is used to increase productivity, improve design quality, and create a database for manufacturing.* (vi) Raster Graphics: Images represented by a grid of pixels, where each pixel contains color information. When scaled up, raster images can appear pixelated or blurry. Examples include photographs.* (vii) Vector Graphics: Images represented by mathematical equations that define points, lines, curves, and shapes. Vector graphics can be scaled to any size without loss of quality. Examples include logos and illustrations.* Q2a: Define Database Management System, and state a procedure for opening a new blank database reference to the Microsoft Access Database System. Q2b: Define the following Microsoft Access Database parts: Q2a: Database Management System (DBMS): A software system designed to create, manage, and retrieve data from a database. It allows users to store, organize, and access information efficiently and securely.* Procedure for opening a new blank database in Microsoft Access: Step 1: Open Microsoft Access. Step 2: Select File from the menu, then click on New. Step 3: Choose Blank database. Step 4: Enter a File Name for your database and click Create. Q2b: (i) Tables: The fundamental building blocks of a database, used to store data in an organized format of rows (records) and columns (fields).* (ii) Forms: User-friendly interfaces for entering, viewing, and editing data in tables. They provide a structured way to interact with the database.* (iii) Reports: Tools used to present data from tables or queries in a formatted, printable layout. They are used for summarizing and analyzing data.* (iv) Queries: Requests for data or information from a database. They allow users to retrieve, filter, and manipulate specific data sets.* (v) Macros: Automated sequences of actions or commands that perform a series of tasks with a single trigger. They simplify repetitive operations.* (vi) Modules: Collections of Visual Basic for Applications (VBA) code that allow users to create custom functions, subroutines, and event procedures for advanced database functionality.* Q3: List eight (8) tools in the Microsoft PowerPoint application package, and explain their functions. 1. Normal View: The primary editing view for designing slides, adding text, images, and other content.* 2. Slide Sorter View: Displays all slides as thumbnails, allowing for easy reordering, deletion, or duplication of slides.* 3. Design Tab: Provides options to apply themes, color schemes, and background styles to slides, ensuring a consistent visual appearance.* 4. Transitions Tab: Offers various visual effects that occur when moving from one slide to the next during a presentation.* 5. Animations Tab: Allows users to apply motion effects to objects (text, images, shapes) on a slide, controlling how they appear, disappear, or move.* 6. Insert Tab: Contains tools to add various elements to slides, such as pictures, shapes, charts, text boxes, videos, and audio.* 7. Review Tab: Includes tools for spell-checking, grammar checking, adding comments, and comparing presentations.* 8. Slide Show Tab: Manages presentation settings, such as starting the show from the beginning or current slide, and setting up custom shows.* Q4: State the formal procedure for performing the following activities, with reference to the Corel Draw application package: i. Starting the Corel Draw package: Step 1: Click on the Start button (Windows logo). Step 2: Navigate to All Programs or All Apps. Step 3: Find and click on the CorelDRAW Graphics Suite folder. Step 4: Click on CorelDRAW to launch the application. ii. Creating a new file in Corel Draw: Step 1: Once CorelDRAW is open, go to the File menu. Step 2: Select New (or press Ctrl+N). Step 3: In the Create a New Document dialog box, specify document settings like name, size, and color mode. Step 4: Click OK. iii. Drawing joining Freehand Lines in Corel Draw: Step 1: From the Toolbox, select the Freehand tool. Step 2: Click and drag on the drawing page to draw the first segment of the line. Step 3: Release the mouse button, then click on the end node of the previously drawn line. Step 4: Drag again to draw the next segment, which will automatically join the previous one. iv. Saving the File in Corel Draw: Step 1: Go to the File menu. Step 2: Select Save (or press Ctrl+S) for the first time, or Save As to save with a new name or location. Step 3: In the Save Drawing dialog box, choose the desired location and enter a File name. Step 4: Select the desired Save as type (e.g., .cdr for CorelDRAW file). Step 5: Click Save. v. Exiting the Corel Draw package: Step 1: Go to the File menu. Step 2: Select Exit (or press Alt+F4). Step 3: If there are unsaved changes, a prompt will appear asking if you want to save them. Choose Save, Don't Save, or Cancel. Q6a: State the advantages of AutoCAD. Q6b: State five (5) major disciplines that use AutoCAD. Q6c: State five (5) features of AutoCAD.
