Web Weavers
This term describes the internet's structure, where no single entity has central control.
Double Jeopardy: Why is the internet designed this way?
Fully Distributed Network
This unique number identifies a device on a network, much like a mailing address
IP Address
Double Jeopardy: What does IP stand for?
This term refers to the volume of data that can be sent over a medium at a given time, measured in megabits per second (MB/s).
Bandwidth
This type of computer stores data that can be accessed by clients over the internet.
A Server
Secure websites use this encrypted protocol instead of HTTP.
HTTPS
This term refers to a set of rules that define how data is transmitted across networks.
Protocols
What is the current widely used version of IP addresses contains and how many bits long is it?
IPv4, 32 Bits
Double Jeopardy: This next-generation IP addressing system will replace IPv4 and features 128-bit addresses.
Triple Jeopardy: What is the largest possible IP address in decimal form?
This term describes the time it takes for a single bit of data to travel from one device to another and back.
Ping
These devices act as traffic managers, directing packets along the best route.
Routers
Cookies store information about your browsing habits. Where are cookies saved?
Locally, on your device
These physical cables, often made of glass or plastic, form the backbone of the internet for long-range data transmission.
Fiber Optic Cables
This system translates human-friendly website names into IP addresses.
DNS (Domain Name System)
Double Jeopardy: Explain the 4 steps of how DNS is used to connect to a website.
Triple Jeopardy: Explain why we use the DNS system instead of just IP addresses.
These three methods are used to transmit bits over a network: electricity, light, and which third method. Give an example.
Radio Waves - 4G/5G/WiFi
This protocol ensures reliable transmission of packets and resends missing ones.
Double Jeopardy: Explain how this protocol works.
TCP (Transmission Control Protocol)
This type of cookie tracks users across different websites and is often used for targeted advertising.
Third-Party Cookie
Data travels over the internet in small chunks, which are later reassembled at their destination. What are these chunks called?
Packets
Give an 3 examples of a Top-Level Domain (TLD).
Double Jeopardy: What is a sponsored TLD and give one example.
.org, .com, .edu, .net, etc
This term refers to the specific location of a file or directory on a web server, often appearing after a domain name in a URL.
Path
Double Jeopardy: Given the following information, describe where the file is located.
downloads/images/dog_photos/polly.jpg
This term describes the process of a client asking for data and server sending back the requested data over the internet.
Request-Response Cycle
Who are considered the "founders of the internet"?
Vint Cerf and Bob Khan
What are the benefits and downsides of using copper cables to connect a network?
Pro: Cheap
Cons: Signal loss over long distances
A DNS attack that tricks users into visiting fraudulent websites by altering DNS records is called this.
DNS Spoofing
How do internet routers determine where to send packets?
They use the IP address and calculate the "cheapest route possible".
Double Jeopardy: Describe the 3 factors discussed in class for determining the cheapest route possible.
Describe what packets are and how they are used to transmit data over the internet.
Small chunks of data that travel independently across networks and are reassembled at their destination to form complete files.
Different protocols were created for different purposes. Name a protocol for each of the following purposes:
Reliability: ______
Security: ______
Hardware: ______
Reliability: TCP, IP
Security: HTTPS, TLS, SSL
Hardware: USB, HDMI
