A global network of interconnected computers and devices. It allows these
devices to communicate and share information with each other.
4. TYPES OF INTERNET
Wireless Internet: Wireless internet enables connectivity without physical cables. This includes
Wi-Fi, which is commonly used in homes, offices, and public spaces, as well as cellular data
networks provided by mobile carriers.
Mobile Internet: Mobile internet allows access to the internet via smartphones, tablets, and
other mobile devices using cellular data networks.
Cable Internet: Cable internet utilizes coaxial cables to provide internet access. It's often
provided by cable television companies and offers high-speed internet service.
Ethernet: Ethernet is a wired network technology commonly used for local area networks
(LANs) in homes, offices, and institutions. It provides high-speed, reliable internet connectivity
through physical cables.
5. Basic Components
• Devices: Devices such as computers, smartphones, tablets, and servers are
connected to the internet.
• Network Infrastructure: This includes physical hardware like routers, switches, and
cables that transmit data between devices.
• Protocols: These are rules and conventions that govern how data is transmitted and
received over the internet. Examples include TCP/IP, HTTP, and DNS.

Internet Protocols(IP)
• TCP/IP: Transmission Control Protocol/Internet Protocol is the foundational
protocol suite of the internet. It breaks data into smaller packets, routes them across
the network, and reassembles them at the destination.
• HTTP/HTTPS: Hypertext Transfer Protocol and its secure variant HTTPS are
protocols used for transmitting web pages and other web content.
• DNS: Domain Name System translates domain names (e.g., www.example.com) into
IP addresses (e.g., 192.0.2.1), allowing computers to locate resources on the internet.
8. To connect to the internet, you need an Internet Service Provider
(ISP). ISPs provide access to the internet through various means
such as DSL, cable, fiber optic, or wireless connections.
Your device (e.g., computer or smartphone) connects to the ISP's
network, which in turn connects to the broader internet.
