Network Basics
The rules that govern how computing devices connect and communicate on the internet.
Protocol
The number of bits we can send in a fixed amount of time (measured in mbps).
Bandwidth
Protocol that breaks data into packets and reassembles it.
TCP
A system of linked pages, programs, and files.
World Wide Web (WWW)
A network of interconnected and communicating objects we use every day.
Internet of Things (IoT)
Processing instructions one at a time.
Sequential Computing
A group of interconnected devices working together for a purpose.
Computer Network
How long it takes data to travel between its source and destination (measured in ms).
Latency
Protocol used to load web pages.
HTTP - HyperText Transfer Protocol
A piece of information placed on your computer from a website, letting you know you visited them.
Cookies
Machines that mimic human intelligence.
Artificial Intelligence (AI)
Splitting tasks across multiple machines.
Distributed Computing
A principle that anyone can connect to the internet and is capable of sending and receiving data.
End-to-End Connectivity
Pieces of binary information that have been formed from digital data.
Packets
The protocol for sending emails.
SMTP -Simple Mail Transfer Protocol
Trusted organization that verifies website identity.
Certificate Authority (CA)
A digital record-keeper for financial transactions of data transfers.
Blockchain
Devices sharing tasks directly with each other.
Peer-to-Peer Network
This architecture concentrates control of the network in one location.
Centralized Network
A type of computer that forwards data across a network path.
Router
The protocol for web addressing.
IP - Internet Protocol
A layer of security wrapped around your communications.
SSL/TLS — Secure Sockets Layer/Transport Layer Security
Data lost when power is off.
Volatile Storage
Processing data by having multiple processors working together on a task simultaneously.
Parallel Computing
This architecture distributes control of the network across multiple locations.
Distributed Network
This is implemented to ensure that if one connection fails, there is an alternative in place to maintain uninterrupted network services.
Redundancy
System that translates website names to IP addresses.
DNS
Language used to create web pages.
HTML - HyperText Markup Language
Data storage that is preserved when the computer is powered off.
Non-volatile Storage
Delivering computing services over the internet.
Cloud Computing
