Acknowledgments, sequencing, and flow control are characteristics of which OSI layer?
Question: Acknowledgments, sequencing, and flow control are characteristics of which OSI layer?
[A].Layer 2
Layer 3
Layer 4
Layer 7
[A].
[B].
[C].
[D].
Answer: Option C
Explanation:
A reliable Transport layer connection uses acknowledgments to make sure all data is transmitted and received reliably. A reliable connection is defined by a virtual circuit that uses acknowledgments, sequencing, and flow control, which are characteristics of the Transport layer (layer 4).

Determine the magnitude and direction of the resultant force FAB exerted along link AB by the tractive apparatus shown. The suspended mass is 10 kg. Neglect the size of the pulley at A.
Question: Determine the magnitude and direction of the resultant force FAB exerted along link AB by the tractive apparatus shown. The suspended mass is 10 kg. Neglect the size of the pulley at A.
[A].FAB = 170.0 N, = 75.0°
FAB = 170.0 N, = 15.0°
FAB = 98.1 N, = 75.0°
FAB = 98.1 N, = 15.0°
