What are network devices?

• Hardware or software components used to connect computers or other devices together to form a network.

• Hardware or software components used to connect computers to the internet

• Components used to connect printers or scanners together

• Devices used to connect televisions or radios together

Name three network protocols.

• SMTP

• POP3

• TCP/IP, HTTP, FTP

• SSH

What are network standards?

• Guidelines and protocols that define how computers and devices communicate in a network.

• The software used to manage and monitor network traffic.

• The physical components of a network, such as routers and switches.

• Rules and regulations that govern the use of network devices.

What are the different types of network components?

• servers, firewalls, repeaters, wireless access points

• printers, scanners, keyboards, monitors

• routers, switches, hubs, modems, network cables, and network interface cards (NICs)

• microphones, speakers, headphones, webcams

What are network services?

• Software applications or processes that run on a network and provide specific functionality or features.

• The process of setting up and configuring a network.

• Physical cables and connectors used to connect devices in a network.

• Hardware devices that connect computers and other devices to a network.

What is the purpose of a router in a network?

• The purpose of a router in a network is to forward data packets between computer networks.

• The purpose of a router in a network is to amplify data packets between computer networks.

What is the difference between a hub and a switch?

• A hub is a simple networking device that connects multiple devices in a network, while a switch is a more advanced networking device that connects multiple devices and intelligently routes network traffic.

• A hub is more expensive than a switch.

• A hub and a switch are the same thing.

• A switch can only connect two devices at a time.

What is the role of TCP/IP in network communication?

• TCP/IP is responsible for reliable, connection-oriented communication and handling addressing, routing, and error detection in network communication.

• TCP/IP is responsible for unreliable, connectionless communication and does not handle addressing, routing, and error detection in network communication.

• TCP/IP is only used for local network communication and cannot be used for communication over the internet.

• TCP/IP is a hardware component that is responsible for transmitting data over a network.

What is the difference between LAN and WAN?

• LAN is a wide network while WAN is a local network.

• LAN and WAN are the same thing.

• LAN is used for personal use while WAN is used for business purposes.

• LAN is a local network while WAN is a wide network.
