The Internet is a global public network of interconnected computers using TCP/IP, providing services like WWW and email.

Write a short note on Internet / Intranet.
Internet
The Internet is a worldwide public network of interconnected computer networks that use the TCP/IP protocol suite. It allows users anywhere to exchange information through services such as the World Wide Web (HTTP), e-mail (SMTP), file transfer (FTP), social media and video calls. It has no single owner, and its networks are linked through ISPs, backbone routers, optical fiber and satellite links.
Intranet
An intranet is a private network within one organization (a college, a bank, a company) that uses the same technology as the Internet (TCP/IP, web browsers, web servers) but is accessible only to authorised members. A firewall protects it from outside access.
| Point | Internet | Intranet |
|---|---|---|
| Access | Public, open to everyone | Private, only authorised users |
| Ownership | No single owner | One organization |
| Scope | Global | Within the organization |
| Security | Lower | Higher (firewall, login) |
| Content | General information | Internal documents, mail, databases |
Uses of an intranet: internal e-mail, file sharing, student or employee records, notices and resource sharing. An extranet extends an intranet to selected outsiders, such as customers and suppliers.
