Introduction to ICT and its role in daily life

The governing concept is file organisation. A folder is a logical container used to group related files and, when needed, other folders in one named location. This makes documents easier to find, open, move, and manage, so option B is correct. Recording sound requires an audio application and microphone, printing requires a printer, and cleaning a monitor is a physical maintenance task; none of these describes a folder's purpose.

The governing concept is ICT-enabled access: digital content can be stored, transmitted and viewed across distance and at a flexible time. A recorded lesson lets the student learn from home rather than travelling to a classroom, and the recording can be replayed when convenient. Therefore option A demonstrates both location flexibility and time flexibility. The other choices retain fixed time, fixed place or manual delivery, so they do not show both benefits.

The governing concept is traceability: a digital transaction can serve as evidence when its essential details are preserved and can be checked. A record showing when the payment occurred, how much was sent and who received it allows the parties or an authorised service to compare claims with transaction data. Therefore option D is correct. Deleted details, an unidentified payment or only a verbal statement provides much weaker evidence.

The governing concept is prevention: public-health communication helps people avoid illness or reduce its risk before a problem occurs. A verified message about vaccination dates and safety precautions can guide people to take timely protective action, so option A is correct. Deleting records harms continuity, publishing private medical information creates a privacy risk, and an unverified cure claim is not reliable preventive health communication.

The governing concept is the economic and livelihood role of ICT. An online marketplace connects a local artisan with customers beyond the nearby area, allowing wider advertising, digital communication, and sales. Option A therefore shows ICT expanding market access and supporting income generation. Hiding information reduces visibility, while an incorrect image and unrecorded orders create confusion and do not represent a beneficial livelihood opportunity.

The governing concept is confidentiality and safe digital communication. Before sending a message or attachment, the sender should check the recipient’s address or account because a mistake can expose personal, financial, academic, or organisational information to an unauthorised person. Option B is correct. Recipient verification does not change message colour, increase internet speed, or reduce file size; those features are unrelated to privacy protection.

The governing concept is account security and privacy on shared devices. If a session remains open on a public computer, the next user may read messages, view personal files, change account settings, impersonate the owner, or misuse stored information. Option D is correct. Signing out ends the authenticated session; it does not increase battery power, organise files automatically, or shut down the internet.

The governing communication principle is clarity under time pressure. During an emergency, people may be frightened or distracted, so complicated words or vague instructions can cause delay and unsafe actions. Option B is correct because simple language helps recipients understand quickly and act properly. Message length, image size, and entertainment do not ensure correct emergency response.

The governing concept is standardisation: applying the same required fields, rules, and format to every entry. Option C is correct because a digital form makes each person provide comparable information, such as name, date, and contact details, in a consistent structure. Option A creates variation, B lacks rules, and D is difficult to record and compare reliably.

The governing concept is volatility. Random access memory, or RAM, is the computer's temporary working memory; it holds active programs and data while power is available. When the computer is switched off, its contents normally disappear, so option A is correct. ROM, an SSD, and a hard disk are non-volatile storage or memory and normally retain their contents without power.

The governing concept is non-volatile memory used for essential instructions. Read-only memory, or ROM, retains its contents when power is removed and traditionally stores firmware or start-up instructions. Therefore option B is correct. Cache and registers are fast working areas, while RAM is also temporary and loses its contents when power is switched off.

The governing concept is the difference between solid-state and mechanical storage. A solid-state drive, or SSD, stores data in flash memory and has no spinning platters or moving read head. It therefore usually provides faster access and quieter operation than a conventional hard disk, making option C correct. CDs, magnetic tape, and floppy disks use slower removable or magnetic media and do not provide this combination.

The governing concept is the two-way role of a device. A touchscreen outputs visual information to the user and also receives touch gestures as input, so option D is correct. A printer mainly produces hard-copy output, a speaker produces sound output, and a scanner mainly captures input from a physical document. Thus only the touchscreen performs both functions in this list.

A filename extension is the ending after the final dot, such as .txt, .jpg, or .pdf. It usually indicates the file format or type and helps the operating system associate the file with a suitable application. Therefore option A is correct. An extension does not describe monitor size, keyboard language, or computer price, so options B, C, and D are unrelated.

Folders provide a logical structure for organising files. Placing related documents together makes them easier to locate, open, rename, copy, and manage, so option B is correct. A folder does not automatically double computer speed, guarantee security or backup, or change the size of its contents. Organisation improves file management, while protection requires permissions, antivirus tools, or backups.

Undo reverses the most recent editing action, such as accidentally deleting selected text, so option D is correct. If the deletion is the latest undoable action, choosing Undo restores the text to the document. Print sends content to a printer, Paste inserts content that has been copied or cut, and Replace substitutes one text string for another. These commands do not directly reverse the mistaken deletion.

Replace is used to find a specified word or phrase and substitute it with another word, often throughout the document, so option C is correct. The user can review each match or choose Replace All when every occurrence should change, while checking context to avoid unintended edits. Select only highlights content, Find locates text without changing it, and Zoom changes the display size rather than the document wording.

The governing concept is the use of standard window-control commands. Maximise enlarges the active application window so that it occupies the available screen area, making option C correct. Restore returns a maximised window to its previous size, Minimise moves it to the taskbar or dock while keeping the program open, and Log out ends the current user session. These commands affect the window or session differently.

A powered computer with no displayed image should first be checked at the display path: confirm that the monitor is switched on, its power cable is connected, and the video cable is firmly attached to the correct port. Option A is therefore the sensible first step. Spelling, printer ink, and folder names cannot normally prevent a basic image from appearing on the monitor.
