Worked Solution & Example Answer:4.1 Name TWO types of users who would find the performance of a standard entry-level computer suitable to their needs - NSC Computer Application Technology - Question 4 - 2019 - Paper 2
Step 1
TWO types of users who would find the performance of a standard entry-level computer suitable to their needs
Answer
-
Home User: A typical home user may require a computer for daily tasks such as browsing the internet, checking emails, and streaming videos. A standard entry-level computer is often sufficient for these purposes.
-
Personal User: Personal users might engage in basic productivity tasks like document editing, photo viewing, and social media, which an entry-level computer can handle adequately.
Step 2
How does an open-source operating system, such as Linux, differ from an enterprise operating system, such as Windows?
Answer
-
Open-source Software Structure: Open-source operating systems like Linux typically have a less formal support structure, which means users have community-based support rather than official tech support.
-
Customization: The source code of open-source systems is available and can be modified, allowing users to customize it to their needs, unlike enterprise systems like Windows, which offer limited customization.
Step 3
TWO advantages for a student using web-based applications over installed applications
Answer
-
Accessibility: Web-based applications can be accessed from any device with an internet connection, which is particularly beneficial for students who work on multiple devices.
-
Reduced Hardware Requirements: Since web applications run on remote servers, students do not need powerful hardware on their devices to use them effectively.
Step 4
TWO practical examples of where RFID tags are used
Answer
-
Inventory Management: RFID tags are used in warehouses and retail to track inventory levels and manage stock efficiently.
-
Identification: RFID tags are implemented in access control systems, such as in keycards for secure buildings, enabling streamlined identification and access.
Step 5
TWO reasons why touch screens are commonly used in portable devices
Answer
-
Intuitive Use: Touch screens provide an intuitive interface, allowing users to interact directly with what is displayed, making navigation easier.
-
Space-saving Design: The elimination of physical buttons allows for a sleeker device design, which is especially valuable in compact portable devices.
Step 6
TWO advantages of using a micro USB port instead of the standard USB port on a smartphone
Answer
-
Compact Size: Micro USB ports are smaller, allowing for thinner and lighter smartphone designs, which is advantageous for portability.
-
Versatility: Micro USB ports can also serve dual purposes, enabling devices to share power and connect with various chargers.
Step 7
TWO reasons why it may be better to use an external hard drive instead of a DVD to backup data
Answer
-
Storage Capacity: External hard drives typically offer significantly more storage capacity than DVDs, making them suitable for backing up large files.
-
Reusability: External hard drives can be overwritten and reused multiple times, whereas DVDs generally allow for limited use before the data is permanently embedded.
Step 8
TWO ways to free up space on an external hard drive that is almost full
Answer
-
Delete Unwanted Files: Regularly removing unwanted files and using disk cleanup tools can significantly free up space on the external hard drive.
-
Data Compression: Compressing data files can reduce their size, allowing more data to be stored on the same external hard drive.
Step 9
TWO reasons why files on an external hard drive could become corrupted when making backups
Answer
-
Power Failure: Unexpected power disruptions during backup processes can lead to file corruption.
-
Faulty Cables: Using damaged USB cables can lead to data transfer errors, resulting in corrupted files on the external hard drive.
Step 10
Step 11
TWO reasons why a program fails to install
Answer
-
Compatibility Issues: The installation media may not be compatible with the operating system or the device it is being installed on.
-
Corrupt Installation File: If the downloaded installation file is corrupted or incomplete, the program will fail to install.
Step 12
Step 13
TWO possible reasons for text being cut off at the edge of a printed document
Answer
-
Printer Settings: The printer settings may not be configured correctly for the document size, leading to cropping of content.
-
Page Margins: If the document's page margins are set too wide, portions of the text may end up outside the printable area, causing them to be cut off.
