Exploring Computer Networks

What is a network topology?

• Network topology describes the software applications in a network.

• Network topology refers to the speed of data transmission.

• Network topology is the arrangement of elements in a computer network.

• Network topology is the type of hardware used in a network.

Name three common types of network topologies.

• Tree

• Star, Bus, Ring

• Hybrid

• Mesh

What is the main function of a router in a network?

• To connect devices within the same network.

• The main function of a router in a network is to route data between different networks.

• To store data for backup purposes.

• To provide internet access to devices.

Differentiate between a switch and a hub.

• A hub connects devices using IP addresses, while a switch uses MAC addresses.

• A switch can only connect devices wirelessly, whereas a hub requires wired connections.

• A hub is faster than a switch because it can handle more data at once.

• A switch is more efficient and intelligent than a hub, as it directs data to specific devices rather than broadcasting to all.

What device is used to connect different networks?

• Hub

• Modem

• Switch

• Router

What are the characteristics of a star topology?

• All devices are connected in a linear fashion

• Each device has equal control over the network

• Characteristics of a star topology include a central hub, easy device addition/removal, isolation of devices, and potential single point of failure at the hub.

• Devices are directly connected to each other without a hub

Explain the concept of a mesh topology.

• A mesh topology is a network configuration where devices are connected in a linear fashion.

• A mesh topology is a network configuration where each device is interconnected, allowing for multiple pathways for data transmission.

• A mesh topology requires a central hub to manage data transmission between devices.

• A mesh topology is characterized by a single point of failure in the network.

What type of network is typically used in a home environment?

• Local Area Network (LAN)

• Personal Area Network (PAN)

• Metropolitan Area Network (MAN)

• Wide Area Network (WAN)

Define a Local Area Network (LAN).

• A Local Area Network (LAN) is a type of network that only connects wireless devices.

• A Local Area Network (LAN) is a network that connects devices across multiple cities.

• A Local Area Network (LAN) is a network that connects devices over the internet.

• A Local Area Network (LAN) is a network that connects devices within a small geographic area.

What is the purpose of a firewall in a network?

• To provide internet access to all devices

• To store data securely in the cloud

• The purpose of a firewall in a network is to protect the network by controlling traffic and preventing unauthorized access.

• To increase the speed of the network
