Explanation:
Copyright law protects the unauthorized access to, reproduction and distribution of copyrighted material. The permission of the copyright holders is needed if any of these are to be done.
If copyrighted material is used without permission such as using software without buying it, that is illegal. If that software is sold or given to someone else, that is also illegal because it can only be distributed or redistributed by the copyright owners or people they have given access to.
Answer:
170 Mbps
Explanation:
Time taken to put data on to the link T1 = 50kB / 1 Gbps = 0.0004096
Time taken for transmission T2 = 2 milliseconds = 2 * 10-3
--> throughput = ( 1 / (1+T2/T1) ) * bandwidth of link
= ( 1 / (1 + 4.8828125) ) * 1 Gbps
= 0.16998672 * 1 Gbps
= 169.98672 Mbps
= 170 Mbps.

Answer:
(b) 7 characters: 4 Numbers, 1 Lowercase Letter, 1 Uppercase letter, 1 Symbol
Explanation:
The best rule that makes a password great is that rule that increases the entropy of the password. The entropy of a password is the measure of how easy it is for the password to be cracked e.g by guessing, by brute force cracking, by dictionary attacks and other related cracking methods.
A rule that makes use of a logical combination of the four types of characters - digits, lowercase letters, uppercase letters and special symbols - gives a greater strength to the password than the rules that just make use of the some of the four types of characters.
Increasing the length of the password too is a great way of increasing the entropy of the password. But then, if there is a trade-off between length and combination, the latter is better.
