The Internet

I'll like to write a short note about what I learnt from FemInstitution concerning the topic 'Internet'. The internet is a worldwide system of computer networks that allows users anywhere to circulate information. It is accessible to anyone with a computer or computer-like connected device.

The internet has two major components: network protocols and hardware protocols such as TCP/IP or a set of rules that devices must follow to complete communication tasks. Hardware includes everything from smartphones and smart devices to cell phone towers, radios, satellite, servers and cables that transmit information.

I also learnt that the the Internet is a global network of physical links, including copper telephone wires, television cables, and fiber optic cables. Even wireless technologies such as Wi-Fi and 3G/4G have physical cords to connect to the Internet.

When you go to a website, your computer makes a request to a server across these cables. Websites are kept on a server, which functions similarly to your computer's hard disk. The server retrieves the website and delivers the right data back to your computer after the request is received. What's even more astounding is that it all happens in a matter of seconds!

I also learnt about HTTP, Packets, Server, Internet Protocol, and DNS

HTTP is a protocol that is used to retrieve resources such as HTML documents. It is the foundation of all data exchange on the Internet, and it is a client-server protocol, which means that requests are initiated by the recipient, which is usually the Web browser.

A packet is a subset of a larger message. Data sent over computer networks*, such as the Internet, is broken down into packets. The computer or device that receives these packets then recombines them.

A server is a software or hardware device that accepts and processes network requests. Servers are in charge of the network's resources. A user might set up a server to regulate network access, send/receive email, manage print jobs, or host a website, for example. They're also capable of doing complex calculations.

The Internet Protocol (IP) is a collection of rules for routing and addressing data packets so that they can transit across networks and reach their intended destination.

And lastly, DNS is a system that allows you to connect to websites by matching human-readable domain names with the unique ID of the server where the website is stored.
