What is an "IP address"?

An IP address, or Internet Protocol address, is a unique string of numbers assigned to each device connected to a network, such as the Internet. It allows devices to identify and communicate with each other by providing an address for sending and receiving data. There are two types of IP addresses: IPv4, which consists of four sets of numbers, and IPv6, a newer version with a longer address format to accommodate more devices. An IP address is essential for browsing the web, sending emails, and using online services.

HTTP

What is "HTTP"?

HTTP, or Hypertext Transfer Protocol, is a system used for transferring data over the Internet. It defines how messages are formatted and transmitted between web browsers and servers. When a user enters a website address, the browser sends an HTTP request to the server where the website is stored. The server then responds with the requested data, such as web pages, images, or other content. HTTP is the foundation of data communication on the World Wide Web, enabling users to access and interact with websites.

What is "bandwidth"?

Bandwidth refers to the amount of data that can be transmitted over a network or Internet connection in a given period, usually measured in bits per second (bps). It indicates the speed and capacity of a connection, with higher bandwidth allowing more data to be transferred at once. In simple terms, bandwidth is like the width of a pipe through which data flows—larger bandwidth means more data can pass through quickly. Bandwidth is important for activities like streaming videos, playing online games, or downloading files, as it affects how smoothly these tasks can be performed.

Domain Name System
phrase
uk flag
/dˌiːˌɛnˈɛs/

a decentralized naming system used on the Internet to translate human-readable domain names into numerical IP addresses that computers can understand, enabling the proper routing of data between devices and servers

What is "DNS"?

DNS, or Domain Name System, is a system that translates human-readable website names, like www.example.com, into numerical IP addresses that computers use to identify each other on the Internet. It acts as a phonebook for the internet, helping users access websites by typing in easy-to-remember names instead of complex numbers. When a user types a website address into their browser, DNS servers quickly find the corresponding IP address, allowing the user to connect to the correct website. Without DNS, people would need to remember long strings of numbers to visit websites.
