Computer Network Basics

What is a network topology?

• A network topology is a type of cloud computing service.

• A network topology is a type of computer virus.

• A network topology is the layout pattern of interconnections between nodes in a network.

• A network topology is a musical instrument.

Explain the difference between physical and logical topologies.

• Physical topology deals with network security, while logical topology deals with network performance.

• Physical topology refers to the speed of data transmission, while logical topology refers to the physical connections.

• Physical topology focuses on software configurations, while logical topology focuses on hardware setups.

• Physical topology deals with the physical layout of the network components, whereas logical topology deals with how data flows within the network.

What are the different types of network topologies?

• Bus, Star, Ring, Mesh, Tree, Hybrid

• Circle

• Line

• Starfish

What is data transmission in computer networks?

• Data transmission is the process of converting data into physical signals for transmission.

• Data transmission refers to the process of encrypting data for secure storage.

• Data transmission in computer networks is the process of sending data from one device to another over a network.

• Data transmission involves storing data on a computer's hard drive.

Describe the process of data transmission through a network.

• The process of data transmission through a network involves singing, dancing, and magic tricks.

• Data transmission through a network is achieved by sending messages via carrier pigeons.

• Network data transmission is completed by telepathically transferring information between devices.

• The process of data transmission through a network includes packetization, addressing, routing, transmission, reception, and delivery.

What are the different network devices commonly used in computer networks?

• repeaters

• routers, switches, hubs, modems, access points, firewalls

• printers

• servers

Explain the function of a router in a network.

• A router functions by forwarding data packets between computer networks based on routing tables.

• A router functions by blocking all incoming data packets.

• A router functions by broadcasting data packets to all devices on the network.

• A router functions by encrypting all data passing through the network.

What is the purpose of a switch in a network?

• The purpose of a switch in a network is to make coffee for users

• The purpose of a switch in a network is to connect multiple devices within a LAN and manage traffic by forwarding data to the intended recipient.

• The purpose of a switch in a network is to play music for connected devices

• The purpose of a switch in a network is to provide weather updates to users

How does a hub differ from a switch?

• A hub forwards data only to the intended recipient, while a switch broadcasts data to all devices.

• A hub is more secure than a switch.

• A hub broadcasts data to all devices, while a switch forwards data only to the intended recipient.

• A hub and a switch perform the same function.

What is the role of a modem in a computer network?

• The role of a modem is to amplify network signals.

• A modem is responsible for encrypting data in a computer network.

• Modems are used to provide power to the network devices.

• The role of a modem in a computer network is to modulate and demodulate signals for data transmission.
