An Internet Standard is a documented agreement that outlines procedures, protocols, or formats, typically developed by the Internet Engineering Task Force (IETF). Its purpose is to ensure that all devices on the internet communicate in the same way, helping to provide a consistent and unified online experience for users worldwide.
Internet Standard Examples
1. HTTP (Hypertext Transfer Protocol)
HTTP, which stands for Hypertext Transfer Protocol, is a foundation of any data exchange on the World Wide Web. It’s a protocol – a set of rules that networked computers follow to “talk to” one another. When you enter a URL in your web browser, it’s HTTP that goes to work, fetching the web page and all its resources, delivering everything to you just as you requested.

HTTP has been in use by the World Wide Web since 1990, providing a standard for web browsers and servers to communicate. It works based on a request-response process: you make a request by clicking a link or typing an URL in your browser, and the server responds by sending you the content of the webpage you’re looking for.
This protocol has gone through several revisions over the years to improve speed, security, and efficiency. The most recent version, known as HTTP/2, was published in 2015 and brought with it more advanced features designed for the modern web.
2. IP (Internet Protocol)
The Internet Protocol, often known as IP, primarily serves two functions. It addresses and labels each packet of data with the sender and receiver’s information, ensuring the information reaches its destination. It also routes the data packets between networks. IP is fundamental to the way the Internet works, helping to ensure messages are sent and received correctly.
In more technical terms, IP works by encapsulating data into packets, then sending them on the best path towards their destination. It’s akin to a postal service for the Internet, assigning addresses to each packet and then deciding on the most efficient route to their destination based on network conditions.
The most common versions of IP in use today are IPv4 and IPv6. IPv4, the older version, uses 32-bit addresses and is gradually being replaced by IPv6, which uses 128-bit addresses, resulting in a significantly larger address space that can accommodate the rapidly growing number of devices accessing the Internet.
3. FTP (File Transfer Protocol)
FTP, an acronym for File Transfer Protocol, is a standard procedure for transferring files from one host to another over a network. It’s commonly used to upload files to a server or download files from a server. It has been a cornerstone of file sharing on the internet since its inception.
In a basic sense, FTP is like a courier for files on the internet. It establishes a connection between host computers so that they can interchange data smoothly. This protocol is particularly beneficial when managing large files or data sets, which could be too big to send by email.
While FTP is an older protocol and there are now more robust and secure options available for file transfer (like SFTP and FTPS), it is still widely utilised for server-to-server transfers. It’s an essential part of maintaining websites, downloading software, or even sharing files in an office network.
Conclusion
HTTP, IP, and FTP are three fundamental Internet Standards that have shaped how we navigate and use the web today. They ensure that data is transported reliably and consistently across the globe, making our interconnected world possible.
Key Takeaways
- Internet Standards are documented agreements developed by the Internet Engineering Task Force (IETF) to ensure the uniformity of internet communication.
- HTTP or Hypertext Transfer Protocol is the protocol used for transferring data over the web, thereby establishing the groundwork of any data exchange on the internet.
- IP or Internet Protocol assigns addresses to data packets and decides their routing across networks, technically acting as a postal service for the internet.
- FTP or File Transfer Protocol is a dependable method for transferring files from one host to another over a network. It’s widely utilized for server-to-server transfers.
- The advent and widespread use of these Internet Standards have revolutionized the way we navigate and utilize the internet today.
Related Questions
1. What are the differences between HTTP and HTTPS?
HTTP is the original protocol used for data transfer on the web while HTTPS, its sequel, adds a layer of encryption for increased security. This is especially important when sending sensitive data, like credit card information or login credentials.
2. What is the main goal of the Internet Protocol?
The primary purpose of the Internet Protocol (IP) is to deliver packets from the source host to the destination host solely based on the IP addresses in the packet headers.
3. Can I use the internet without these protocols?
No, these protocols are the foundation of internet communication. They ensure your data gets from its source to its destination correctly and efficiently.
4. Are FTP transfers secure?
FTP itself is not encrypted, meaning that the data being transferred can potentially be intercepted and read. For secure file transfers, alternatives like SFTP (SSH File Transfer Protocol) or FTPS (FTP Secure) are often used.
5. What happens when data is sent from one device to another on the internet?
When data is sent from one device to another on the internet, it is divided into packets, tagged with IP addresses by the IP protocol, transferred according to HTTP or another protocol, and then reassembled upon reaching the destination.
