The internet Flashcards
What is the Internet?
The Internet is a global Wide Area Network (WAN) connecting millions of Local Area Networks (LANs) across the world.
What is the major service provided by the Internet?
The major service provided by the Internet is the World Wide Web (WWW).
What are some topics covered in the lesson on the Internet?
Topics covered include IP Addresses, Domain Name Services, Internet Service Providers, Devices for Accessing the Internet, The World Wide Web, URLs, HTTP and HTTPS, and HTML.
What is an IP Address?
An IP Address is a unique address for connected networks on the Internet, using numeric structures to identify devices.
What is the limitation of IPv4?
The limitation of IPv4 is its capacity to allow only roughly four billion address combinations.
What does DNS stand for and what is its purpose?
DNS stands for Domain Name Service, which maps human-readable domain names to IP addresses, facilitating accessibility on the Internet.
What role do Internet Service Providers (ISPs) play?
ISPs connect LANs to the Internet using various technologies, providing Internet access and routing requests through their networks.
Name some devices used for accessing the Internet.
Devices include switches, wireless access points, routers, and modems, which enable network connectivity and Internet access.
What is the World Wide Web?
The World Wide Web is a service running on the Internet, providing web pages containing text, images, videos, etc., linked via a hypertext system.
What scripting language is used for generating web pages?
HyperText Markup Language (HTML) is used for generating web pages, containing text and formatting instructions.
What is the significance of IPv6 in addressing the limitations of IPv4?
IPv6 addresses the limitations of IPv4 by using a larger bit allocation (128 bits) per address, allowing for a significantly larger number of possible addresses to accommodate the growing number of devices connected to the Internet.
Explain the function of routers in Internet communication.
Routers transmit traffic between entire networks, such as between a LAN and the Internet, by receiving outbound and inbound traffic and smartly routing it to its intended destination, ensuring efficient data transmission.
What is the significance of the World Wide Web in Internet services?
The World Wide Web provides access to a vast array of resources, including web pages containing text, images, videos, and more, linked via a hypertext system, making information accessible and interconnected across the Internet.
How do domain names improve accessibility on the Internet?
Domain names provide human-readable addresses for resources on the Internet, making it easier for users to remember and access websites, services, and files without having to memorize IP addresses.
Why is understanding IP addressing important in Internet communication?
Understanding IP addressing is crucial in Internet communication as it allows devices to be uniquely identified on the network, facilitating data routing and ensuring that information is sent to the correct destination.
