OSI Model

3. a small computer network that connects electronic devices within a person's workspace
5. smallest unit of data transmitted over a network
7. created the WIFI standards for data transmission
9. a computer network that connects users and computer resources within a geographic area, typically a city or metropolitan area
12. First layer of OSI model and transmits data in the fomr of 0s and 1s
14. Contains information that allows a network to transmit a packet.
16. a conceptual framework that describes how networking systems communicate and send data:
17. a protocol that recalls the data in a computer system to prevent errors
18. a group of interconnected devices
20. also known as tailor, provides proof if data has been tampered over transmission
21. a universal language that uses only the numbers 0 and 1 to represent information in computers.

1. Contains the actual data being transmitted over the network
2. Second layer that handles transmission errors and transmission protocols
4. a computer network that connects multiple local area networks (LANs) within a limited geographical area
6. a high-speed networking standard that transmits data in fixed-size cells, typically 53 bytes.
8. Physical chord used in both the first layer and second layer of the OSI model
10. connects devices within a network (often a local area network, or LAN*) and forwards data packets to and from those devices.
11. Uses virtual circuits to enable a single router to link many faraway locations.
13. Transmits data packets over radio frequency
15. device that allows your computers, smartphones, tablets, and other devices to connect to the internet
19. device that connects two or more packet-switched networks or subnetworks
