Understanding Computer Networks

What is a computer network?

• A computer network is a collection of unrelated devices that do not communicate.

• A computer network is a type of software used for programming.

• A computer network is a single computer that operates independently.

• A computer network is a system of interconnected computers and devices that communicate and share resources.

What is one advantage of using a computer network?

• Resource sharing

• Increased security risks

• Higher costs for maintenance

• Limited access to information

What is one disadvantage of using a computer network?

• Increased speed of data processing.

• Enhanced communication between users.

• Improved data sharing capabilities.

• Increased vulnerability to security breaches.

Name a basic component of a network.

• Modem

• Switch

• Access Point

• Router

What are the two main types of networks?

• Cloud Network and Hybrid Network

• Virtual Private Network (VPN) and Storage Area Network (SAN)

• Metropolitan Area Network (MAN) and Personal Area Network (PAN)

• Local Area Network (LAN) and Wide Area Network (WAN)

What is a local area network (LAN)?

• A LAN is a type of internet service provider.

• A LAN is a network that connects devices globally.

• A local area network (LAN) is a network that connects devices within a limited geographical area.

• A LAN is a network that only connects mobile devices.

What is a wide area network (WAN)?

• A wide area network (WAN) is a local network for a single building.

• A wide area network (WAN) is a type of wireless network only.

• A wide area network (WAN) connects devices within a single room.

• A wide area network (WAN) is a network that covers a broad area, connecting multiple smaller networks.

What does network topology refer to?

• The arrangement of elements in a computer network.

• The type of cables used in a network.

• The software applications running on network devices.

• The speed of data transmission in a network.

Name one type of network topology.

• Ethernet topology

• Star topology

• Server-client topology

• LAN topology

In a school project, Heri, Arif, and Rudi are setting up a network for their presentation. They decide to use a star topology. What does this mean for their network layout?

• A star topology connects nodes in a circular layout.

• A star topology is a type of wireless network.

• A star topology is a network layout where all nodes are connected to a central hub.

• A star topology has no central hub and connects nodes directly to each other.
