Across
- 5. stages in a network that can receive and transmit data packets; routers are nodes in communication networks
- 7. the time interval allowed to elapse before an acknowledgement is received(in the ARQ error detection method)
- 8. a method used to check if data has been transferred correctly; it makes use of even parity(an even number of 1-bits) and odd parity(an odd number of 1-bits)
- 10. a type of encryption key that is known to all users
Down
- 1. a horizontal and vertical parity check on a block of data being transmitted
- 2. the original text/message before it is put through an encryption algorithm
- 3. the actual data being carried in a data packet
- 4. encrypted data that is the result of putting a plaintext message through an encrytion algorithm
- 6. data that can be sent in one direction only
- 9. data that can be sent in both direction simultaneously
