A network is a system of interconnected devices that share resources and exchange data. Networks can be computer networks, professional networks, or social networks. 

Computer networks

How they work: Devices in a computer network use protocols to send and receive data over physical or wireless connections. 

Types of networks: Networks can be local area networks (LANs) or wide area networks (WANs). LANs connect devices within a short distance, like in an office, while WANs connect devices across continents. 

Purpose: Networks allow devices to communicate, share resources, and use services. 

Examples: Networks are used in businesses, homes, and schools. 

Professional networks 

Purpose

Networking helps professionals develop relationships with people and companies in their field.

Examples

Networking opportunities can be found at trade shows, seminars, conferences, college alumni groups, and private clubs
