Answer:

(d) 0.875 erlangs

Explanation:

In a digital network, the traffic intensity = \dfrac {aL}{R}

where

a = average arrival rate of packets = 35 objects downloaded per second

L is the average packet length = 50,000 bits (e.g. in bits), and

R is the transmission rate = 2 Mbps = 2,000,000 bits per second

Traffic Intensity = \dfrac {aL}{R}=\dfrac {50000 X 35}{2000000}=\dfrac {1700000}{2000000}=0.875

g How safe is to have a LinkedIn account where you have published all the important information about yourself
irina [24]

Answer:

LinkedIn is very safe

Explanation:

LinkedIn is very safe, that being said you should never post private information about yourself anywhere that you do not want others to see/know. LinkedIn is a job recruiting and networking site, meaning that all the information that you have or will be publishing there should be related to your career. There is no reason for you to publish private information such as document numbers, social security number, address, bank account info, etc.
