Your friends are planning a trip to the Cango Caves - NSC Computer Application Technology - Question 10 - 2017 - Paper 2

You can book a car on a mobile device by using a dedicated mobile application (app) provided by the rental agency. These apps offer an intuitive interface for searching and booking vehicles.

1. Record GPS coordinates of the locations you visit, which can be later accessed through mapping applications.
2. Use geo-tagging features on your photos; when you take a picture, your device can store the location data, which can be viewed on a map later.

You could use online translation tools or apps to translate your destination into the taxi driver's language. Alternatively, you could show the driver a mapped destination on your mobile device, facilitating communication.

1. Reviews may be biased or misleading, as some might be posted by individuals with a vested interest or genuine preferences differing from yours.
2. Relying solely on online information might ignore local favorites, leading to missed opportunities for discovering quality shops.

1. There may be a hardware failure on the mobile device, rendering it unable to process transactions.
2. The user may lack internet access or have insufficient data allocated for the transaction, preventing payment from being completed.

1. Ensure that no one is watching you as you enter your PIN when making payments to prevent card cloning.
2. Use payment service apps on your mobile device instead of entering your bank card information directly, enhancing security.

1. Smartphone cameras often have smaller sensors, which can limit their ability to perform in low light situations compared to DSLRs with larger sensors.
2. Professional cameras usually have better lenses providing greater optical zoom and manual control settings that contribute to superior image quality.

Your friends might not have GPS or internet connectivity in the caves, which would prevent the map app from providing real-time turn-by-turn directions.

1. Use the cropping tool to cut out unnecessary sections of the photograph, focusing on the desired subject.
2. Utilize image editing software, such as Paint, to erase or cover unwanted elements in the image.

1. Using Wi-Fi hotspots can save on data costs associated with mobile network usage for VoIP calls.
2. Wi-Fi generally provides a more stable connection with lower latency, improving call quality.

1. A public Wi-Fi network can be hacked, putting your personal information at risk if the network is compromised.
2. There may be rogue Wi-Fi hotspots set up by malicious actors to capture private data transmitted over the network.

1. Satellite broadband is usually much slower than other forms of internet connection, which can limit functionality.
2. Line of sight might be a limitation, as poor weather conditions can significantly degrade signal quality.

Poor video quality of a Skype call could stem from low bandwidth availability, which limits data transmission speed, causing video lag and pixelation, or from unstable connectivity that disrupts the signal.

You could share the photographs stored in your friend's cloud account by asking them to grant you access or by providing you with a password for the account, allowing you to view and download the pictures.
