3.1 When setting up a small office network, some possible essential pieces of equipment could include cables and routers - NSC Information Technology - Question 3 - 2019 - Paper 2

The purpose of a router is to direct data packets between different networks. It connects multiple devices and ensures that data is sent to the correct destination by determining the best path for the data to travel.

1. Wireless networks are easy to set up and allow for the addition of new devices without the need for extensive cabling.
2. They provide flexibility, enabling users to connect from various locations within the coverage area.

An access point is a device that allows wireless devices to connect to a wired network using Wi-Fi. It functions as a sender and receiver, transmitting data over radio signals.

Piggybacking refers to the unauthorized use of someone else's wireless network without permission. This can occur when users connect to an unsecured network, potentially leading to data breaches.

1. Change the default password of the network to a strong, original password.
2. Implement a good password policy by regularly updating the password and limiting access to authorized users only.

A dynamic website generates content tailored to individual users, enhancing the user experience. It is interactive, allows for easy updates based on user preferences, and can provide personalized experiences for each visitor.

To ensure your website appears in search results, you should utilize search engine optimization (SEO) techniques. This includes optimizing your website's content, using relevant keywords, and ensuring it is indexed by search engines.

A protocol is a set of rules governing the exchange of data between devices. It ensures that data is transmitted accurately and efficiently.

Using HTTPS is advisable because it provides a secure connection by encrypting data transmitted between the user and the web server. This protects sensitive information from eavesdropping and man-in-the-middle attacks.

A PAN (Personal Area Network) has a limited range and is designed for small connections, making it unsuitable for accessing business files from various locations over the internet.

1. A VPN (Virtual Private Network) offers a secure connection over public networks, protecting data from unauthorized access.
2. It provides remote access to network resources, enabling users to access business files from any location.

RIA (Rich Internet Application) refers to web applications that provide the functionalities and features of traditional applications, enhancing user engagement and interactivity.

An example of a RIA is Google Docs, which allows users to create and edit documents in real-time online.

1. An app increases convenience for users, allowing them to access services directly from their mobile devices.
2. An app can enhance marketing efforts by utilizing app stores for better visibility and promotion.

Location-based computing uses the physical location of devices to provide relevant information and services to users based on their geographical location.

Technologies such as GPS (Global Positioning System) and geolocation services are used to implement location-based computing.

A podcast is a digital audio file or recording that is available for streaming or download, often organized into episodes or series.

Streaming is a method of transmitting media content in real-time over the internet, allowing users to listen or watch without having to download the entire file first.
