QuestionAnswer
Computing Device a machine that can run a program, including computers, tablets, servers, routers, and smart sensors
Computing System a group of computing devices and programs working together for a common purpose
Computing Network a group of interconnected computing devices capable of sending or receiving data.
Path the series of connections between computing devices on a network starting with a sender and ending with a receiver.
Bandwidth the maximum amount of data that can be sent in a fixed amount of time, usually measured in bits per second.
Protocol An agreed-upon set of rules that specify the behavior of some system
IP Address The unique number assigned to each device on the Internet.
Internet Protocol (IP) a protocol for sending data across the Internet that assigns unique numbers (IP addresses) to each connected device
Router A type of computer that forwards data across a network
Redundancy the inclusion of extra components so that a system can continue to work even if individual components fail, for example by having more than one path between any two connected devices in a network.
Fault Tolerant Can continue to function even in the event of individual component failures. This is important because elements of complex systems like a computer network fail at unexpected times, often in groups.
user data protocol UDP The goal is to send information quickly without worrying about accuray.
Transmission Control Protocol (TCP) It’s slower but more accurate.
net neutrality the idea that everything on the internet should be open to everyone
User Datagram Protocol (UDP) Send all the packets but don’t check if they all get through or arrive in the right order.
User Datagram Protocol (UDP) Useful when split seconds matter more than correcting errors, like video-conferencing, live streaming, online gaming
the digital divide the difference between people who have and don't have the internet and devices
Transmission Control Protocol (TCP) Number packets so they can be re-ordered, confirm all were received, resend any missing packets. Multiple back and forth confirmations between sender and receiver.
Transmission Control Protocol (TCP) Useful when accuracy matters more than saving a split second, like sending emails, photos, or just browsing websites
Datastream Information passed through the internet in packets.
Packet Metadata Data added to packets to help route them through the network and reassemble the original message.
Transmission Control Protocol (TCP) A protocol for sending packets that does error-checking to ensure all packets are received and properly ordered
Vint Cerf and Bob Kahn invented the internet
Packet A chunk of data sent over a network. Larger messages are divided into packets that may arrive at the destination in order, out-of-order, or not at all.
User Datagram Protocol (UDP) A protocol for sending packets quickly with minimal error-checking and no resending of dropped packets
Scalability the capacity for the system to change in size and scale to meet new demands
World Wide Web a system of linked pages, programs, and files
The Domain Name System (DNS) the system responsible for translating domain names like example.com into IP addresses
World Wide Web a system of linked pages, programs, and files
The Domain Name System (DNS) the system responsible for translating domain names like example.com into IP addresses
Hypertext Transfer Protocol (HTTP) a protocol for computers to request and share the pages that make up the world wide web on the Internet
The World Wide Web are files, web pages and media. The Internet is the network we use to access those files. How is the internet different from the world wide web?

What is a datastream quizlet?

Datastream. - The way in which information travels on the Internet, not as a single piece but in chunks. Packet. - Chunk of data and its metadata, used to route and reassemble information on the Internet.

Which of the following is the best description of how routing works on the Internet?

Which of the following is the best description of how routing works on the Internet? A computer stores the destination IP address in the IP packet header and sends the packet to the nearest router.

How does the Internet protocol allows devices to easily connect and communicate on the Internet?

Internet Protocol allows devices to easily connect and communicate on the Internet by having a shared protocol through which data can be sent across the Internet through unique numbers, or IP addresses, to each connected device.

What problem solves HTTP?

When you visit a website you're actually getting sent a file by a server. HTTP is solving the problem of how to ask for that file. Your computer and that server communicate using a protocol called HTTP. HTTP is plain-text, so it literally includes the ASCII word "GET ..." and the file name requested.
