Bit: The smallest representation of data that a computer can understand
Border Gateway Protocol (BGP): A protocol by which routers share data with each other
Broadcast: A type of Ethernet transmission, sent to every single device on a LAN
Broadcast address: A special destination used by an Ethernet broadcast composed by all Fs
Cable categories: Groups of cables that are made with the same material. ****Most network cables used today can be split into two categories, copper and fiber
Cables: Insulated wires that connect different devices to each other allowing data to be transmitted over them
Carrier-Sense Multiple Access with Collision Detection (CSMA/CD): CSMA/CD is used to determine when the communications channels are clear and when the device is free to transmit data
Client: A device that receives data from a server
Collision domain: A network segment where only one device can communicate at a time
Computer networking: The full scope of how computers communicate with each other
Copper cable categories : These categories have different physical characteristics like the number of twists in the pair of copper wires. These are defined as names like category (or cat) 5, 5e, or 6, and how quickly data can be sent across them and how resistant they are to outside interference are all related to the way the twisted pairs inside are arranged
Crosstalk: Crosstalk is when an electrical pulse on one wire is accidentally detected on another wire
Cyclical Redundancy Check (CRC): A mathematical transformation that uses polynomial division to create a number that represents a larger set of data. It is an important concept for data integrity and is used all over computing, not just network transmissions
Data packet: An all-encompassing term that represents any single set of binary data being sent across a network link
Datalink layer: The layer in which the first protocols are introduced. This layer is responsible for defining a common way of interpreting signals, so network devices can communicate
Destination MAC address: The hardware address of the intended recipient that immediately follows the start frame delimiter
Duplex communication: A form of communication where information can flow in both directions across a cable
Ethernet: The protocol most widely used to send data across individual links
Ethernet frame: A highly structured collection of information presented in a specific order
