2. Networks are critical for the use of email, instant messaging, and fixing.
4. Layer 7, supplies network services to end-user applications
7. connects multiple devices devices within a network. Can be managed or unmanaged
9. Used to make routing decisions. Can be static or dynamic
11. Personal Area Network
15. protocol connection-oriented, secure reliable conection
16. stands for modulator and demodulator, used to convert analog to digital signals
18. translates digital info into signals used to transfer data (ethernet or WI-FI)

1. Networks centralize data and make it more accessible to users.
3. unique 48 bit hardware number that is embedded, consist of 6 octets
5. Layer 1, responsible for the actual transmission of digital data.
6. Network permits the sharing of files, database, and media
8. Layer 6, it handles the syntax processing of message data.
10. the maing goal is sending datagrams, as quickly as possible
12. ___is two or more devices connected to exchange information
13. 128 bits, consist of 8 octates
14. Layer 3, works for the transmission of data from a source device in one network to a destination in another network
17. layer 2, trnasmmit data to its destination device using the MAC address
