Answer:
All traffic that flows between the laptop and VPN server is encrypted.
Explanation:
A Virtual Private Network (VPN) is a "tunnel" connection between computers that performs just like a regular point-to-point network connection (that is, IP address to IP address). It has the added feature that encryption is enabled so that no intermediate server (or computer or line monitor, etc.) can decode the information that is in the data portion of the packets.
Answer:
The oldest malware vector was emails.
Explanation:
Websites were not widespread early on into the internet, however it was very easy to have a virus that uses an email contact list, where it can send itself to other email addresses and spread.
Answer:
A. 4 CPUs and 6 megabyte cache memory
B. 1.3157 x10^-9 nanoseconds
Explanation:
The Intel core i5 7500 is a seventh generation central processing unit with a 4 CPU core and a 6 megabyte cache memory. It executes task at a clock cycle of 5 clock cycle at a speed of 3.8 GHz.
The relationship between frequency and clock cycle is,
Clock cycle = 1 / ( frequent).
So, One clock cycle = 1 / 3.8 GHz
= 0.3 x10^-9
For five clock cycles = 5 x 0.3 x10^-9
= 1.3157 x10^-9 nanoseconds.
Answer:
C) Plants
Explanation:
"Ecosystem" is the topic. Then "Plants" is the sub topic. Next the "Number of trees" and "Number of shrubs" branch out from there (Pun intended (; ).
