Bit means "binary digit". A bit is a single digit in a binary number. A bit can either be 0 or 1.
A byte is 8 bits.
Number system that has 2 digits, 0 and 1. This is how computers represent numbers at the base level.
A semiconductor device used to amplify or switch electronic signals and electrical power, functioning as an on/off switch in computing
The process of converting information or data into a specific format that can be understood or processed by a computer.
ASCII is the standard protocol for encoding text information as bits. The ASCII table assigns a unique binary number to every text character.
Unicode is a system that lets computers show and use all kinds of characters from different languages and writing systems around the world.
A kilobyte (kB) is 2^10 bytes (1024 bytes) of binary data.
A megabyte (MB) is 2^20 bytes (1024 kB) of binary data.
A gigabyte (GB) is 2^30 bytes (1024 MB) of binary data.
Images are made up of pixels, which are essentially a grid of values. Each value, or pixel, encodes the color at that position in the image.
The RGB encoding scheme allows us to encode colors as numeric data. It defines the amount of Red, Green, and Blue light in a pixel. Each color channel can have a value between 0 and 255.
A terabyte (TB) is 1024 GB of binary data.
A philosophy of making information and knowledge open and accessible to all people. A network of networks built on open, agreed upon protocols.
A network where devices are connected via physical cables.
A network where devices connect without physical cables, typically using radio waves.
The process of varying a signal to transmit data.
Undersea cables used for transmitting telecommunications signals across oceans.
A computer scientist known as one of the "fathers of the internet."
A new 128 bit version of the Internet Protocol.
The protocol that defines the payout of an an Internet address.
An agreed upon set of rules that outlines how to communicate or send information.
The original 32 bit IP protocol that was created in the 1980s.
The process of sending data between two computers on the internet. The data is sent through routers that determine the route.
Allows for sending MULTIPLE packets between two computers. TCP checks that all packets arrived and can be put back in the proper order. The metadata must include a destination IP address, a from IP address, the message size and the packet order number.
An access point that allows for network management and security configuration.
a system that will operate with no interruption when one or more of its components fail
When data is passed from one network segment to another.
The number of hops it takes for data to get to its final destination.
Advanced Research Projects Agency Network, precursor to the modern internet
UDP is often used in real-time applications where timely delivery of data is more important than the accuracy of delivery. UDP does not number the packets and it does not retransmit packets that are lost.
A float, or floating point value, is a numeric value that can have decimal level precision (ex: 3.14)
The way humans communicate with each other, like English, Spanish, or Mandarin.
A set of instructions (commands) and rules used to communicate with computers. Examples include Python, JavaScript, and HTML.
A way to classify the kind of information you can use in programming, like numbers, words, or true/false values.
