Across
- 2. layer of TCP/IP that enables client application programs to access the other layers and defines the protocols that applications use to exchange data (1st word)
- 3. topology in which one station transmits signals which travel in both directions along a single transmition segment (most common topology)

- 31. distributive computing model in which some of the processing power is located within small inexpensive client computers, and resides literally on desktops/laptops/handhelds
- 34. topology in which all devices on the network connect to a single hub
- 35. international telephone standards for digital communication
- 36. specifies the physical medium to carry signals
- 38. logging on to one computer system and doing work on another
- 40. simple devices that connect network components, sending a packet of data to all other connected devices
- 42. more intelligence than a hub; can filter & forward data to a specified destination on the network
- 43. commercial organization with a permanent connection to the internet that sells temporary connection to retail subscribers
- 46. modulator-demodulator; connects your computer to the internet using a cable network
- 47. layer of TCP/IP that provides the application layer with communication and packet services (1st word)
Down
- 1. slicing digital messages into parcels called packet, sending the packets along different communication paths as they become available & then reassembling the packets once they arrive at their destination
- 5. two or more connected computers

- 16. treats all processors equally and is used primarily in small networks
- 18. address; domain name + directory + document name, etc
- 19. secure, encrypted, private networks that have been configured within a public network to take advantage of the economies of scale and managemnt facilities of large networks
- 20. networks of connected wireless devices that are embedded into the physical environment to measure many points over large spaces

- 32. layer of TCP/IP responsible for addressing, routing, and packaging data packets called IP datagrams
- 33. the way a LAN's components are connected
- 37. equal to one cycle of the medium
- 39. the movement of data between computers; establish a connection between computers, sequences the transfer of packets, and acknowledges the packets sent (acronym)
- 41. the range of frequencies that can be accomodated on a particular telecommunication chanel
- 44. topology which connects network components in a closed loop; messages pass in one direction
- 45. technology for tracking the movement of goods throughout the supply chain (acronym)
