HTTP (Hypertext Transfer Protocol) is the set of rules for transferring files (text, graphic images, sound, video, and other multimedia files) on the World Wide Web.

The Hypertext Transfer Protocol is an application protocol for distributed, collaborative, and hypermedia information systems. HTTP is the foundation of data communication for the World Wide Web.

Default value is a predesigned value or setting that is used by a computer program when a value or setting is not specified by the program user.

Modem is abbreviation for Modulator – Demodulator. Modems are used for data transfer from one computer network to another computer network through telephone lines. The computer network works in digital mode, while analog technology is used for carrying massages across phone lines.

Modulator converts information from digital mode to analog mode at the transmitting end and demodulator converts the same from analog to digital at receiving end.

TCP/IP is a set of data communication protocols that allow computers to connect to the Internet and private networks. Each protocol performs a different task and facilitates data exchange between various applications.

Transmission Control Protocol/Internet Protocol, or TCP/IP for short, is divided into two protocols: the Transmission Control Protocol (TCP) suite and the Internet Protocol (IP) suite.

The TCP suite processes and handles data from applications, while the IP suite is designed to accommodate the transmission and receipt of application data across a network.

The TCP/IP is a combination of four different layers: the application, transport, Internet and network access layers. Without TCP/IP, devices would be unable to connect to the Internet or share data.

One of the main benefits of TCP/IP is that it accepts data of any size and chops it up into smaller, more manageable chunks called packets. A packet contains all the information a network needs to deliver it to its destination and then to acknowledge delivery.

A computer network is a set of computers connected together for the purpose of sharing resources. The most common resource shared today is connection to the Internet. Other shared resources can include a printer or a file server.

Web page is a document commonly written in Hyper Text Markup Language (HTML) that is accessible through the Internet or other network using an Internet browser. A web page is accessed by entering a URL address and may contain text, graphics, and hyperlinks to other web pages and files.

Internet access is ability of individuals and organizations to connect to the Internet using computer terminals, computers, and other devices, and to access services such as email and the World Wide Web.

A website is a collection of related web pages, including multimedia content, typically identified with a common domain name, and published on at least one web server. ‎

A site or website is a central location of various web pages that are all related and can be accessed by visiting the home page using a browser.
For example, the Computer Hope website address (URL) is https://www.computerhope.com.

The term gateway refers to a piece of networking hardware that has the following meaning: In a communications network, a network node equipped for interfacing with another network that uses different protocols.

‎ A gateway is a node (router) in a computer network, a key stopping point for data on its way to or from other networks.

A gateway is a data communication device that provides a remote network with connectivity to a host network. A gateway device provides communication to a remote network or an autonomous system that is out of bounds for the host network nodes. Gateways serve as the entry and exit point of a network, all data routed inward or outward must first pass through and communicate with the gateway in order to use routing paths. Generally, a router is configured to work as a gateway device in computer networks.

A router is a device that forwards data packets along networks. It is connected to at least two networks and are located at gateways.

A router is a networking device that forwards data packets between computer networks. Routers perform the traffic directing functions on the Internet. A data packet is typically forwarded from one router to another router through the networks that constitute an internetwork until it reaches its destination node.
