Across
- 1. Application Layer / is the interface that the user sees and interacts with, allowing the user to “click send” to send an email, for example, or move a file from a local computer to a network drive.
- 3. responsible for determining the path that packets take as they are routed on networks.
- 4. / Interface Process Messenger
- 6. / ipconfig, ping, nslookup, tracert
- 9. / TCP—both organizes/managing the data in each packet of information sent and routs that information according to an IP (Internet Protocol) number…
- 11. / will provide the path taken between computers
- 12. control / control—message from receiving computer that packets have been received and the next one can be sent.
Down
- 1. Layer / When the data reaches the Transport Layer, it is segmented into data packets. This is where the first innovations in packet frame technology (TCP) come into play
- 2. Layer / This layer conveys the bit stream - electrical impulse, light or radio signal -- through the network at the electrical and mechanical level.
- 5. Layer / Translates or converts the data from the Application Layer so that it can be read by the Application layer of the receiving computer—it does this in standard ways, such as converting text to ASCII or HTML, graphics to jpg or gif, or video to QuickTime or AVI.
- 7. / = about 4.3 billion (2^32) We have run out! Hence…
- 8. Layer / Addresses the packets for delivery (IP number)—networks use TCP/IP
- 10. Layer / Controls the communication link or session between the sending and receiving computers (starts and stops communication)
