I think that calculation tools would be the answer. <span>Excel contains calculation tools not available in access. Excel enables you to create formulas for ease in operation for future purposes. Almost all operations can be found in excel which cannot be found in Access.</span>
Answer:
a. Systems testing
Explanation:
According to my research on information technology, I can say that based on the information provided within the question the term being defined is called System Testing. Like mentioned in the question, this is a technique used in order to evaluate the complete system the system's compliance against specified requirements, which tests its functionalities from an end-to-end perspective in order to evaluates patches used to close software vulnerabilities and make sure it complies with all policies.
I hope this answered your question. If you have any more questions feel free to ask away at Brainly.
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.
Answer:
A. The comments are adequate to describe the function.
Explanation:
C++ programming language comments starts with two forward-slash ("//") and can be written above a code statement or at the right-hand side of the code statements
The comments of the area() function with three parameters width, height, and length are adequate to describe the function as it does not need to end with a semi-colon.
