What is a network?

• A single computer used for personal tasks

• A group of computers linked to transmit data

• A device for storing files

• A type of software for managing tasks

Answer explanation

A network is defined as a group of computers linked together to transmit data. This allows for communication and resource sharing, making the second option the correct choice, while the others describe different concepts.

Which of the following is an example of a network?

• A smartphone

• The internet

• A printer

• A keyboard

Answer explanation

The internet is a vast network that connects millions of devices globally, allowing them to communicate. In contrast, a smartphone, printer, and keyboard are individual devices, not networks.

What does LAN stand for?

• Large Area Network

• Local Area Network

• Long Area Network

• Linked Area Network

Answer explanation

LAN stands for Local Area Network, which refers to a network that connects computers and devices in a limited area, such as a home, school, or office. The other options are incorrect definitions.

What is the main difference between a LAN and a WLAN?

• LANs use wireless connections, WLANs use cables

• LANs are used in homes, WLANs in businesses

• LANs use cables, WLANs use wireless connections

• LANs are faster than WLANs

Answer explanation

The main difference is that LANs (Local Area Networks) typically use cables for connections, while WLANs (Wireless Local Area Networks) use wireless technology. This distinction is crucial for understanding network setups.

What is a benefit of using a WLAN over a LAN?

• Increased range and speed

• No trailing cables

• Easier to secure

• More reliable connections

Answer explanation

A key benefit of using a WLAN over a LAN is that it eliminates trailing cables, allowing for greater mobility and flexibility in device placement. This makes WLANs more convenient in environments where cable management is challenging.

What is a Storage Area Network (SAN)?

• A type of WLAN

• A type of LAN

• A type of PAN

• A type of WAN

Answer explanation

A Storage Area Network (SAN) is a specialized network designed to provide access to consolidated block-level storage. It operates at the LAN level, connecting servers to storage devices, making 'A type of LAN' the correct choice.

What is a SAN primarily used for?

• Data transfer

• Storage

• Networking

• Communication

Answer explanation

A SAN (Storage Area Network) is primarily used for storage, providing a dedicated network that connects storage devices to servers, allowing for efficient data management and access.

What does a WAN typically cover?

• A single room

• A building

• A large geographical area

• A small office

Answer explanation

A WAN (Wide Area Network) typically covers a large geographical area, connecting multiple locations over long distances, unlike local networks that are limited to smaller spaces like a room or building.

What is an example of a Personal Area Network (PAN)?

• Connecting a smartphone to a laptop

• Connecting multiple offices

• Connecting a city-wide network

• Connecting a country-wide network

Answer explanation

A Personal Area Network (PAN) is a small network used for connecting devices within a close range, such as connecting a smartphone to a laptop. The other options involve larger networks, which do not qualify as PANs.

Why might businesses use a WAN?

• To connect devices within a single room

• To connect LANs across different locations

• To store data locally

• To enhance personal device connectivity

Answer explanation

Businesses use a WAN to connect LANs across different locations, enabling communication and data sharing between geographically dispersed offices, which is essential for operational efficiency.
