The answer is true.
Telepresence is essentially things like video-chat that allows people to participate in meetings even if they are not physically present.
I hope this helps! :)

Answer:
C. Under the condition that value != list[list.length − 1]
Explanation:
In the loop, the value of flag gets overwritten in each iteration, so only the last value of the list matters. Flag is true when value is not equal to the last list element, which is at position list.length-1.
Answer:
I am pretty sure its the Visual card
Answer: An example of such a scenario would be when the user name and password meant to allow access to a customers bank account statement is cracked by unauthorized people this causing alteration (in the form of data diddling attacks) in the data contained in the statement. This is a compromise in integrity.
Explanation:
Confidentiality entails securing things people want to remain secret. An account statement of a bank customer is a confidential document which is to be kept secret. A password allows access to it.
Integrity implies receiving a sent data/information as accurately as it came from a sender. A data diddling attack alter integrity because the original information is altered by an unauthorized person.
Answer:
A tape drive provides sequential access storage, unlike a hard disk drive, which provides direct access storage. A disk drive can move to any position on the disk in a few milliseconds, but a tape drive must physically wind tape between reels to read any one particular piece of data.
Explanation:
Architecturally tape drives are sequential storage, meaning that if you need to access some data at the end of the tape you needed to seek to the end and retrieve it. This can take seconds or minutes. Disks, OTOH are random access. Some hard drives use rotating media and movable heads , so the seek times are instantaneous , at least compared with tape drives. However, like tapes, there is a big advantage to using a rotating hard drive as sequential storage. It takes time, measured in milliseconds, for a head to move to another track. So traditionally, random access is much slower than sequential access.
SSDs have no internal moving parts so random access occurs in the same time frame as sequential access. Moreover, these drives usually have very high performance. For example, they can saturate a SATA data link, meaning that the SATA connection to the motherboard is now a bottleneck in disk access.
At one time tape drives were very popular. They were a low-cost alternative to using disks as backup. They were especially useful when IBM invented the Winchester “fixed” drive. This meant that the hard drive is fixed within its enclosure like they are today. Prior to this one could remove the drive pack and replace it. This was helpful when upgrading to a new version of the operating system as it was simple to replace the older drive pack should there be a problem.
Tape drives can be used in larger data centers, due to the fact that tape volumes can be removed and replaced so that the actual tape drive can backup many disk sets. Also the tape volumes can be stored off-site or in a fire-proof vault so this is valuable in a data recovery scenario.
