The basic concepts of networks are:

• Nodes and links

• Data and storage

• Hardware and software

• Users and permissions

Networks are used in sharing of resources and backups by:

• allowing multiple users to access shared files and devices

• restricting access to resources

• preventing data sharing

• isolating devices from each other

What are the common types of networks such as LAN, WAN, and Internet?

• LAN, WAN, and Internet are types of networks.

• LAN and WAN are not types of networks.

• Only LAN is a type of network.

• None of these are types of networks.

Explain server-based networks and client-server models.

• Server-based networks centralize resources and management, while client-server models distribute tasks between providers and requesters.

• Server-based networks are decentralized, while client-server models centralize resources.

• Server-based networks and client-server models are identical in function and structure.

• Server-based networks focus on peer-to-peer communication, unlike client-server models.

What is P2P in networking?

• A centralized network model

• A peer-to-peer network model

• A client-server network model

• A hierarchical network model

Network media refers to the various types of communication channels used to interconnect devices on a network. Which of the following is an example of network media?

• Ethernet cables

• USB drives

• RAM

• CPU

Wireless networks are:

• a type of network that uses cables to connect devices

• a type of network that uses radio waves to connect devices

• a type of network that uses satellites to connect devices

• a type of network that uses fiber optics to connect devices

What are the threats to networks?

• Viruses and malware

• Natural disasters

• Hardware failures

• All of the above

What is cloud and cloud computing?

• A type of weather phenomenon

• A technology for storing and accessing data over the internet

• A type of personal computer

• A programming language

A computer network is a system that allows computers to:

• communicate and share resources

• operate independently without interaction

• function without electricity

• store data permanently
