6.1 The company has an online version of their magazine hosted on a website - NSC Information Technology - Question 6 - 2021 - Paper 2

The main purpose of running a CSS (Cascading Style Sheets) on a website is to separate content from design. This allows web developers to design the layout and appearance of web pages just once and automatically update the design on all web pages, enhancing consistency and saving time.

SQL (Structured Query Language) is used on a website to interact with databases. It allows for the retrieval, insertion, and deletion of data stored in a database, enabling dynamic content to be displayed based on user interactions.

Two hardware components on the motherboard that can be upgraded are the RAM (Random Access Memory) and the CPU (Central Processing Unit).

Two benefits of using desktop computers over laptops are: 1. Larger screens that enhance user experience, and 2. Easier repair and upgrade options due to modular design.

One way to improve the speed of the computers without adding hardware is to run a system cleanup to remove unnecessary files or disable specific features that may be slowing down performance.

Two ways to dispose of computers in an eco-friendly manner are: 1. Recycling the materials to prevent e-waste, and 2. Donating working parts to organizations that can use them.

Office automation refers to the use of technology to perform routine office tasks and processes that were previously done manually. It includes tasks such as data entry, scheduling, and communication, aimed at increasing efficiency and reducing human intervention.

Two advantages of office automation to workers are: 1. It saves time by handling repetitive tasks automatically, and 2. It increases accuracy in data processing, reducing the chances of human error.

Employees would be able to connect to the company’s Wi-Fi network by using a hotspot or access point equipped with a Wi-Fi modem, along with a wireless network interface card (NIC) on their devices.

Attenuation refers to the loss of signal strength as it travels through a medium. This results in a weakened signal and can lead to data transmission errors or decreased performance in network communications.

Two reasons why WiMAX technology is considered more suitable than Wi-Fi are: 1. It has a wider range of coverage, allowing for connectivity over greater distances, and 2. It offers faster speeds and higher bandwidth, making it ideal for data-intensive applications.

Microblogging is the practice of posting short messages or updates online, typically in real-time. These posts can include text, images, videos, and links, and are often limited in character count, allowing users to share thoughts quickly and efficiently with their audience.

Two potential health problems caused by excessive use of social media are: 1. Anxiety due to constant comparison with others, and 2. Eye strain from prolonged screen time.

The abbreviation IoT stands for 'Internet of Things.'

Two ways in which IoT devices connect to the internet are: 1. Through Wi-Fi or wireless connectivity, and 2. By using cellular networks.

Distributed computing is a computational model where processing tasks are distributed across multiple computing devices that work together to solve a single problem, allowing for enhanced processing power and efficiency.

One example of where distributed computing could be used is in weather modelling, where data from multiple sources is processed collectively to create accurate predictions.

Blockchain technology is a decentralized digital ledger system that securely records transactions across multiple computers in such a way that the registered information cannot be altered retroactively, ensuring transparency and security.

A multi-factor authentication system works by requiring users to provide two or more verification factors to gain access to a system or application. This could include something they know (like a password), something they have (like a smartphone for a code), or something they are (like a fingerprint).

Electronic media uses Digital Rights Management (DRM) to protect content from unauthorized access or copying. It employs encryption techniques to control access to the content and prevent illegal distribution.

Two tasks that can be performed with files in the folder with Read permissions are: 1. List the files in the folder, and 2. Open files for viewing.

The 'Full control' permission would typically be allocated to an Administrator or any person in charge of managing the files in the folder.
