a) <br />i. World Wide Web: The World Wide Web (WWW) is a system of interlinked hypertext documents and multimedia content that is accessed via the internet. It allows users to navigate between different web pages using hyperlinks.<br /><br />ii. Software: Software refers to the programs and applications that run on a computer. It is a collection of instructions that tell the computer how to perform specific tasks.<br /><br />iii. Internet: The Internet is a global network of interconnected computer networks that communicate with each other using standardized communication protocols. It allows for the exchange of information and communication between devices worldwide.<br /><br />iv. Web Browser: A web browser is a software application that allows users to access and navigate the World Wide Web. It retrieves and displays web pages, images, and other multimedia content.<br /><br />v. Search Engine: A search engine is a software system designed to search the internet for information based on user queries. It indexes and organizes web pages to provide relevant search results.<br /><br />b) Advantages of using Microsoft Excel:<br />1. Data Analysis: Excel provides powerful tools for data analysis, such as pivot tables, charts, and formulas, which allow users to manipulate and analyze large datasets.<br />2. Automation: Excel's macro feature enables users to automate repetitive tasks, saving time and increasing efficiency.<br />3. Collaboration: Excel allows for real-time collaboration and sharing of workbooks, making it easier for teams to work together on projects.<br /><br />c) Off-shelf software vs. Tailor-made software:<br />Off-shelf software: This type of software is pre-built and available for purchase or download from the market. Examples include Microsoft Office, Adobe Photoshop, and antivirus programs.

Tailor-made software is designed and developed to address unique requirements that off-shelf software cannot fulfill.<br /><br />d) Two reasons why a dictionary is an important tool in word processing applications:<br />1. Spell Checking: A dictionary helps the word processing application identify and correct spelling errors by comparing the words in the document with the words in the dictionary. This ensures that the text is free of spelling mistakes.<br />2. Auto-correction: The dictionary also aids in auto-correction, where the application automatically corrects misspelled words by suggesting the correct spelling based on the dictionary. This feature helps improve the overall quality of the text.<br /><br />e) Diagram explaining the composition of a computer:<br />[Insert diagram showing the main components of a computer, such as the central processing unit (CPU), memory (RAM), storage devices (hard drive, SSD), input devices (keyboard, mouse), output devices (monitor, speakers), and motherboard.]<br /><br />f) Difference between application software and system software:<br />Application software: Application software refers to programs designed to perform specific tasks for users, such as word processing, spreadsheet management, or graphic design. Examples include Microsoft Word, Adobe Photoshop, and Google Chrome.<br /><br />System software: System software refers to the programs that manage and control the computer hardware and provide a platform for running application software. Examples include operating systems like Windows, macOS, and Linux.<br /><br />g) Editing an entry in a cell:<br />To edit an entry in a cell, follow these steps:<br />1.
