Test: Internet and it's Services - 1 - SSC CGL MCQ

The term "Internet" represents a network of networks, encompassing both private and public networks that are interconnected globally. This structure allows for the exchange of information and communication between diverse computer systems. The Internet's origins trace back to the 1950s, evolving from projects like ARPANET and NSFnet. This interconnected nature highlights the Internet's essence as a vast network facilitating global communication and information exchange.

The connection between the University of California at Los Angeles and the University of Utah in 1969 marked the beginning of ARPANET, the world's first operational packet-switching network. This event laid the foundation for what would later evolve into the modern Internet, facilitating communication between different academic institutions and U.S. defense facilities. ARPANET was a crucial development in the history of networking technologies, paving the way for the interconnected digital landscape we experience today.

One of the key advantages of the Internet is its global reach, enabling seamless communication and connections with individuals worldwide. This vast network fosters easy and instant communication between people irrespective of geographic distances. The Internet's global connectivity facilitates information dissemination, collaboration, and interaction on a scale that was previously unimaginable, revolutionizing the way we communicate and share knowledge across borders.

A significant drawback of the Internet is the prevalence of unchecked, incorrect, or irrelevant information due to the lack of stringent regulation. This issue can lead to the spread of misinformation, making it challenging for users to discern accurate and reliable sources from misleading or false content. The open nature of the Internet allows for the unrestricted sharing of data, which can contribute to the dissemination of inaccurate information, emphasizing the critical importance of verifying sources and exercising caution when consuming online content.

In the mid-1980s, the National Science Foundation introduced NSFnet with the primary goal of establishing a high-capacity network that surpassed the capabilities of ARPANET. Unlike ARPANET, NSFnet was designed to support advanced research initiatives and academic pursuits, aiming to enhance networking capabilities for scientific and educational endeavors. By pioneering a more robust network infrastructure, NSFnet played a pivotal role in the expansion and evolution of the Internet, laying the groundwork for its widespread adoption and utilization in diverse fields.

Transmission Control Protocol (TCP) is responsible for routing messages from the sender to the receiver in a reliable manner. It breaks down data into packets at the source and reassembles them at the destination, ensuring the accurate delivery of information across networks.

Wireless broadband connections in challenging deployment areas rely on radio links for communication. This technology enables data transfer without the need for physical cables, making it feasible in regions where traditional wired connections are difficult to establish.

The Post Office Protocol version 3 (POP3) is a standard protocol used by local email clients to retrieve emails from a remote mail server over a TCP/IP connection. It enables users to access their emails securely and efficiently.

Broadband over Power Line (BPL) Internet connection delivers broadband access through existing electric power distribution networks, providing speeds up to 3 Mbps. This technology is particularly suitable for rural areas with power infrastructure but limited broadband options.

HyperText Transfer Protocol (HTTP) defines how messages are formatted and transmitted over the web. It specifies the actions that web servers and browsers should take in response to various commands, facilitating the exchange of information between clients and servers.

The term "WWW" stands for World Wide Web, which is a system of Internet servers that support hypertext and multimedia to access various Internet protocols on a single interface. This system facilitates information exchange between computers on the Internet.

A web browser is a software application used to locate, retrieve, and display content on the World Wide Web. It functions by delivering web pages to requesting computers, allowing users to access and interact with information on the Internet.

A graphical web browser supports both text and graphic information. It allows users to view and interact with web content that includes both textual and visual elements, enhancing the browsing experience.

A web server is a computer that runs websites, delivering web pages to requesting computers over the Internet. It plays a crucial role in hosting and serving web content to users who access websites through their web browsers.

The first Uniform Resource Locator (URL) was created by Tim Berners-Lee in 1991. URLs serve as web addresses that identify the location of specific web pages on the Internet, allowing users to access online content easily.
