HTTP stands for Hypertext Transfer Protocol.
Explanation:
- Hypertext Transfer Protocol (HTTP) is an application protocol for transmitting hypermedia documents, such as HTML files, over the internet.
- It is the foundation of data communication on the World Wide Web and is commonly used to retrieve resources, such as web pages, images, videos, etc.
- HTTP operates on a client-server model, where a client, typically a web browser, sends a request to the server, and the server responds with the requested resource.
- The protocol defines how the messages are formatted and transmitted, as well as the actions that the client and server should take in response to different requests and status codes.
- HTTP uses a stateless protocol, meaning that each request and response is independent of any previous request or response.
- It is an application layer protocol that relies on lower-level protocols, such as TCP/IP, for reliable transmission of data.
- HTTP is a text-based protocol, with requests and responses consisting of headers and optional message bodies.
- The protocol supports various methods, such as GET, POST, PUT, DELETE, etc., which define the actions to be performed on the requested resource.
- HTTP is widely used for accessing web pages, APIs, and other resources on the internet, making it a fundamental component of the modern web.

Internet Protocols
- The rule followed in the transmission of information on the Internet is known as Internet Protocols.
- Internet Protocols are a set of rules that govern the way data is transmitted and received over the Internet.
- These protocols define the format and structure of data packets, as well as the procedures for establishing and terminating connections.
- Internet Protocols ensure that data is properly routed and delivered to its intended destination.
- Some of the most commonly used Internet Protocols include TCP/IP (Transmission Control Protocol/Internet Protocol), HTTP (Hypertext Transfer Protocol), FTP (File Transfer Protocol), and SMTP (Simple Mail Transfer Protocol).
- TCP/IP is the foundational protocol suite used for communication on the Internet.
- HTTP is used for transmitting web pages and other resources over the Internet.
- FTP is used for transferring files between computers.
- SMTP is used for sending emails.
- Internet Protocols enable seamless and reliable communication between devices connected to the Internet.
- They play a crucial role in ensuring the interoperability and functionality of the Internet.

What all do you need to connect to the Internet?
To connect to the internet, you will need the following:
1. Internet Service Provider (ISP):
- An ISP is a company that provides internet access to individuals or organizations. It is essential to have an active internet service subscription from an ISP.
2. Modem:
- A modem is a device that allows you to connect your computer or other devices to the internet through your ISP. It converts the data signals from your ISP into a format that your devices can understand.

Answer:

Modem is a piece of hardware that serves in exchanging information between two computers through the cables.

Explanation:

• A modem is a device that modulates and demodulates signals to transmit digital information between computers over a communication network.


• It converts digital signals from a computer into analog signals that can be transmitted over telephone lines or cable lines.


• The modem at the receiving end then demodulates the analog signals back into digital signals for the receiving computer.


• Modems can be connected to computers via various types of cables, such as telephone lines, Ethernet cables, or coaxial cables.


• They are commonly used for connecting to the internet, as they allow computers to communicate with internet service providers (ISPs) over telephone or cable lines.


• Modems can also be used for connecting computers in a local area network (LAN) or for establishing point-to-point connections between two computers.


• Wire, scanner, and none of these are not correct answers as they do not serve the purpose of exchanging information between two computers through cables.
