RECAP TIME

4. Data represented by distinct 0s and 1s, used in computers and most modern networks.
7. Factors that weaken or disrupt wireless signals, such as obstacles, other radio signals, or environmental conditions, leading to reduced performance.
8. The process of changing a carrier wave to embed information for transmission.
10. The way radio waves or other electromagnetic signals travel through the air, including phenomena like reflection, diffraction, and absorption.
12. Communication allows for data to flow in both directions, either one way at a time (half) or simultaneously (full).
13. A dedicated communication link between two specific devices, ensuring private and direct data transfer.
14. Combining multiple data streams onto a single communication channel to increase efficiency.

1. A type of cable with a central conductor surrounded by insulation and a braided shield, offering good noise immunity but limited bandwidth compared to newer technologies.
2. A technology that uses thin strands of glass or plastic to transmit data as pulses of light, offering high bandwidth and immunity to electromagnetic interference.
3. Sending a single message to all devices on a network segment, allowing for efficient communication with multiple receivers.
5. Maximizing the use of available network resources by allowing more data to travel simultaneously.
6. The real-world measure of how much data successfully passes through a network connection in a given time, often lower than the theoretical maximum.
9. A smooth, flowing wave that can represent varying values like sound or temperature.
11. Data moves in only one direction, like a radio broadcast where the receiver cannot send back.
