• What is Network :-

A network consists of two or more computers that are linked in order to share resources(such as printers and CDs), exchange files, or allow electronic communications. The computers on a network may be linked through cables, telephone lines, radio waves, satellites, or infrared light beams 

 

Types of Network

    LAN (Local Area Network)

    WAN (Wide Area Network)

    MAN(Metropolitan Area Network)

    PAN (Personal Area Network)  

    CAN( Campus Area Network) 

 

  LAN (Local Area Network) :- A LAN is a computer network that consists of and Access points, 

cables, routers, and switches that enable devices to connect to web servers internal servers

within a single building, campus, or home network,

LAN

WAN(Wide Area Network ) :- A wide area network (also known as WAN), is a large network of information that is not tied to a single location. WAN can facilitate communication, the sharing of information and much more between devices from around the world through a WAN provider.

Switch :- 
स्विच कंप्यूटर नेटवर्क में एक उपकरण है जो अन्य उपकरणों को एक साथ जोड़ता है। ... स्विच पोर्ट 

से जुड़ा प्रत्येक उपकरण किसी भी समय किसी भी अन्य पोर्ट में डेटा स्थानांतरित कर सकता है और
