Exploring Data Communication Concepts

What are the main types of networks?

• Internet, Intranet, Extranet, Cloud

• VPN, VLAN, WLAN, SAN

• Bluetooth, Ethernet, Fiber, DSL

• LAN, WAN, MAN, PAN

Define a Local Area Network (LAN).

• 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 within a limited geographical area.

• 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 over the internet.

What is a Wide Area Network (WAN)?

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

• A Wide Area Network (WAN) is a network that connects only computers within the same city.

• A Wide Area Network (WAN) is a type of wireless network only used for mobile devices.

• A Wide Area Network (WAN) is a local network for a single building.

Explain the concept of a Metropolitan Area Network (MAN).

• A MAN connects devices within a single building only.

• A MAN is a type of wireless network that covers a small area.

• A Metropolitan Area Network (MAN) connects multiple LANs within a city or large campus, facilitating high-speed data transfer.

• A MAN is primarily used for connecting personal devices like smartphones.

What is the difference between a peer-to-peer and a client-server network?

• In a peer-to-peer network, devices share resources directly; in a client-server network, clients request services from a central server.

• In a peer-to-peer network, a central server manages all resources.

• Client-server networks allow direct sharing of files between devices.

• Peer-to-peer networks require a dedicated server for resource management.

What is a star topology?

• A star topology is a network layout where all nodes are connected in a ring.

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

• A star topology is a type of wireless network without any central device.

• A star topology connects all nodes directly to each other without a central hub.

Describe a bus topology.

• A bus topology requires multiple communication lines for each device.

• A bus topology connects devices in a circular manner.

• A bus topology is a wireless network configuration.

• A bus topology is a network layout where all devices share a single communication line (the bus) for data transmission.

What are the advantages of a ring topology?

• Complexity in troubleshooting

• Limited scalability options

• Advantages of ring topology include simplicity, predictable data transmission, ease of adding/removing devices, and efficient bandwidth usage.

• High cost of implementation

What is a hybrid topology?

• A hybrid topology is a type of software application.

• A hybrid topology is a network topology that combines characteristics of multiple topologies.

• A hybrid topology is a single, fixed network structure.

• A hybrid topology only uses wireless connections.

What is the OSI model in data communication?

• The OSI model is a three-layer framework for application development.

• The OSI model is a seven-layer framework for network communication.

• The OSI model is a five-layer framework for network communication.

• The OSI model is a ten-layer framework for data storage.
