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 presentation. It allows developers to define the layout and appearance of web pages once, which can then be automatically updated across all pages. This ensures a consistent look and feel while making it easier to maintain and update the design.

SQL (Structured Query Language) is used on a website primarily to interact with the database. It allows for storing, retrieving, and manipulating data, making the website more dynamic and interactive by retrieving specific information based on user inputs.

This indicates that the website potentially uses location-based services to customize and provide relevant content to users, enhancing the overall user experience.

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

Two benefits of using desktop computers over laptops are:

1. Larger screens, which can enhance productivity and user experience.
2. Easily expandable/upgradable hardware, allowing for better customization according to user needs.

One way to improve the speed of the computers is to disable specific features or applications that are not in use, which will free up system resources and enhance performance.

Two eco-friendly ways to dispose of computers are:

1. Recycle the material to recover useful components.
2. Donate functioning equipment to organizations or individuals in need.

Office automation refers to the process of using technology to create, store, manipulate, and relay office information needed for accomplishing basic tasks and goals. It involves the use of computers and software to streamline and automate routine office tasks.

Two advantages of office automation to workers are:

1. Saves time by automating repetitive tasks, allowing workers to focus on more critical activities.
2. Increases accuracy in routine tasks, reducing human error.

Employees can connect to the company’s Wi-Fi network by using a hotspot or access point, which would allow them to establish a wireless connection using their devices.

Attenuation in a network refers to the reduction of signal strength as it travels through a transmission medium, which can limit the distance over which data can be transmitted effectively.

A fiber optic cable can be used as a communication medium to limit attenuation, as it allows signals to travel longer distances with minimal loss.

Two reasons why WiMAX technology is considered to be more suitable than Wi-Fi technology are:

1. Wider range of coverage, allowing it to reach greater distances than standard Wi-Fi.
2. Faster speed and higher bandwidth, enabling more data transfer at once.

Microblogging is a form of blogging that enables users to post short updates, known as 'micro-posts,' such as text, images, and videos to a public or semi-public web space. It focuses on brevity and instantaneous communication, often used on platforms like Twitter.

Two potential health problems caused by extensive use of social media are:

1. Anxiety, stemming from the pressure to maintain a certain online presence or appearance.
2. Eye strain, resulting from prolonged screen time and reduced blink rates.

The abbreviation IoT stands for Internet of Things, which refers to the network of interconnected devices that can communicate and share data with one another.

Two ways in which IoT devices connect to the internet are:

1. Wi-Fi/Wirelessly, utilizing wireless communication protocols.
2. Cellular, using mobile network connections to access the internet.

Distributed computing refers to a computing model in which processing tasks are divided among multiple computers that work together to solve a single problem. This allows for greater efficiency and effective resource sharing.

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

Blockchain technology is a decentralized digital ledger system that records transactions across many computers in such a way that the recorded transactions cannot be altered retroactively. This ensures transparency, security, and trust, making it suitable for applications like cryptocurrencies and contract management.

A multi-factor authentication system works by requiring users to provide two or more independent credentials to verify their identity before gaining access. This could include something they know (a password), something they have (a mobile device for OTP), or something they are (biometrics), thereby enhancing security.

Electronic media uses DRM (Digital Rights Management) to protect content from unauthorized access and distribution. It prevents illegal copying and ensures that content creators are compensated for their work.

Two tasks that can be performed with files in the folder with Read permissions are:

1. Open files to view their contents.
2. Download files to a local device.

The ‘Full control’ permission is usually allocated to the Administrator, who manages file and folder permissions and can perform all operations on the files.
