O a.
O b.
O c.
O d.
Select one:
O a. security algorithm for wireless networks
O b. security algorithm for ethernet
O c. none of the mentioned
O d. security algorithm for usb communication
What transport service does an application need? (best choice)
fast speed, synchronous transfer, excellent throughput
3 way handshake, errorless transfer, full CPU access
No.3
data integrity, timing, throughput, security
ability to correct errors, synchronous transfer, excellent throughput
No.6
The Medium Access Control (MAC) protocol is used to provide the data link
layer of the Ethernet LAN system. The entire frame (data and CRC) is
preceded by a small idle period (the minimum inter-frame gap, 9.6
microsecond (US)) and a
preamble (including the start of
frame delimiter).

O a. 4 Bytes
O b. 8 Bytes
O c. 16 Bytes
O d. 1 Bytes
