Big Idea 6 Flashcards
What is the main role of the internet?
To connect devices and networks all over the world.
What does an end-to-end architecture facilitate?
It facilitates connecting new devices and networks on the internet.
Through what are devices and networks that make up the internet connected using?
Adresses and protocols.
What does the Internet protocol (IP) address connect?
Connecting new devices to the Internet is enabled by assignment of an internet protocol address.
What does the Domain Name System (DNS) do?
Translates domain names to IP addresses.
What is a new protocol that has been established to handle routing of more devices?
IPv6
What standards are overseen by the Internet Engineering Task Force (IETF)?
Standards such as hypertext transfer protocols (HTTP), IP, and simple mail protocol (SMTP)
The domain name system and IP addresses are hierarchal. True or false?
True.
Is routing on the internet fault tolerant?
Yes and it is also redundant.
Why the hierarchy and redundancy?
Hierarchy and redundancy help systems scale. The redundancy of routing (i.e., more than one way to route data) between two points on the Internet increases the reliability of the Internet and helps it scale to more devices and more people.
Why are interfaces and protocols efficient?
They enable widespread use of the internet.
Explain the packet-switching that undergoes within the internet.
The internets a packet-switched system through which digital data is sent by breaking the data into blocks of bits called packets, which contain both the data being transmitted and control information for routing the data.
What is the name for the standard for packets and routing?
TCP/IP
What are some standards for sharing information and communicating between browsers and servers on the web?
HTTP and secure sockets layer/transport layer security (SSL/TLS)
What is the measurement of bit rate?
The bandwidth system-the amount of data (measured in bits) that can be sent in a fixed amount of time
