Understanding Internet and Web Technologies

What is the primary characteristic that defines the internet?

• A single network with limited access

• A network of interconnected networks, spanning the world

• A private network for organisational use

• A network with no physical connections

Answer explanation

The internet is primarily defined as a network of interconnected networks, allowing global communication and access. This distinguishes it from private or limited networks, emphasizing its expansive and inclusive nature.

Which of the following is NOT a type of internet connection?

• Copper-cable

• Optical-fibre

• Satellite

• Bluetooth

Answer explanation

Bluetooth is a wireless technology for short-range communication, not a type of internet connection like Copper-cable, Optical-fibre, or Satellite, which provide internet access.

Which characteristic is NOT typically associated with internet connections?

• Speed

• Range (distance)

• Storage capacity

• Colour

Answer explanation

Colour is not a characteristic associated with internet connections. Key characteristics include speed, range (distance), and storage capacity, but colour does not apply to the functionality or performance of internet connections.

What type of network is the World Wide Web (www) primarily associated with?

• Intranet

• Extranet

• Internet

• Local Area Network (LAN)

Answer explanation

The World Wide Web (www) is primarily associated with the Internet, which is a global network of interconnected computers. Intranets and extranets are more localized, while a Local Area Network (LAN) is limited to a small geographic area.

Which type of network is described as private with closed access?

• Internet

• Intranet

• Extranet

• Virtual Private Network (VPN)

Answer explanation

An intranet is a private network accessible only to an organization's members, making it closed to outsiders. In contrast, the internet is public, and extranets and VPNs allow limited external access.

What is the main purpose of an extranet?

• To provide public access to information

• To allow private, part shared access

• To restrict access to a single organisation

• To connect devices within a home

Answer explanation

The main purpose of an extranet is to allow private, part shared access between an organization and its partners or clients, facilitating secure communication and collaboration while restricting access to unauthorized users.

Which of the following is a characteristic of a network?

• Colour

• Purpose

• Speed

Answer explanation

An extranet is a private network that allows controlled access to partners, enabling secure resource sharing. Unlike the internet, it provides a secure environment, making it the most suitable choice for companies collaborating with partners.

What is the primary purpose of a network?

• To increase the weight of data

• To facilitate communication and resource sharing

• To change the colour of data

• To decrease the speed of data transfer

Answer explanation

The primary purpose of a network is to facilitate communication and resource sharing among devices, allowing users to exchange information and access shared resources efficiently.

Which of the following is a common issue related to access to networks?

• Unlimited speed

• Restricted access

• Infinite storage

• Colourful interfaces

Answer explanation

Restricted access is a common issue related to networks, as it can limit users' ability to connect and utilize resources. In contrast, unlimited speed, infinite storage, and colorful interfaces are not typical access issues.
