Explain the term "data security".

(a) Utility softwares and system softwares. Step 1: Utility softwares are programs designed to maintain, configure, analyse and optimise a computer system. Examples include antivirus software, disk defragmenter, backup utility and compression software. Step 2: System softwares are programs that act as an interface between the application softwares and the hardware. Examples include operating systems (e.g. Windows, Linux) and utility softwares. (b) Operating system is a set of programs that manages all the hardware in a computer system. (c) Utility programs are softwares that maintain and configure the hardware in a computer. (d) Two reasons to partition a computer hard disk drive: Step 1: To separate the operating system files from user files for easier backup and recovery. Step 2: To allow installation of multiple operating systems on the same hard disk drive. (e) Steps to duplicate a diskette in a diskette type drive: Step 1: Insert the source diskette into the floppy disk drive. Step 2: Select the 'copy disk' or 'diskcopy' command from the utility or DOS prompt (e.g. DISKCOPY A: B:). Step 3: When prompted, remove the source diskette and insert the target (blank) diskette into the drive. Step 4: Confirm the copy process and wait for completion. Step 5: Verify the copy, eject both diskettes and label the target diskette. (f) Three desktop options in a word processor (e.g. MS Word view options), explained with description of illustrations: Step 1: Print Layout view - Shows the document as it will appear when printed, with margins, headers and page breaks. (Illustration: Page with ruler, margins visible, text flowing between pages.) Step 2: Normal view - Simplified view for editing, without full page formatting, faster for large documents. (Illustration: Continuous text without page breaks, wider workspace.) Step 3: Outline view - Hierarchical view showing document structure with headings levels. (Illustration: Headings collapsible, numbered levels like 1., 1.1, bullets.) (g) Difference between copy and cut: Copy: Duplicates the selected text/data to the clipboard, leaving the original intact. Cut: Removes the selected text/data from its location and places it in the clipboard. (h) Two advantages of using database management system (DBMS): Step 1: Reduces data redundancy by storing data in a centralised location. Step 2: Provides data security through user access controls and encryption. (i) Cisco Packet Tracer (or Microsoft Visio for network diagrams). (j) Two utility softwares for maintenance of a diskette: Step 1: Scandisk - Checks and repairs disk errors. Step 2: Defragmenter - Rearranges files for faster access.
