Answer:

The correct answer to the following question will be "Physical Layer".

  • The lowest layer of the OSI reference model is the physical layer. It's in charge of having to send bits from one desktop to the next.
  • This layer isn't acquainted with the interpretation of the parts and is concerned with setting up a physical wireless connection and sending and receiving signals.
  • This layer relies on aspects of the hardware, such as wires, transmitters, and network interface tokens.

iren2701 [21]

Answer:

A concern that might be expressed by the legal department after reviewing the SLAs and terms of service is:

c. Ensuring that there is a guarantee that the cloud service provider will provide notice in the event that they decide to discontinue operations.

Explanation:

The SLA that the legal department will review should include a description of the services to be provided, expected service levels, measurement metrics for each service, each party's duties and responsibilities, and the contract remedies or penalties for breach, among others.  But the legal department will be mostly concerned with legal remedies during breaches, liability limitation and warranties, and intellectual property protection issues than with more technical issues.  This is despite the fact that all the terms of the SLA will be diligently reviewed by the legal department.

You also learn in class that one kilobyte of computer memory will hold about 2/3 of a page of typical text (without formatting).
Travka [436]

Answer:

The flashdrive can hold 35389 400-pages-books

Explanation:

If \frac{2}{3} of a page occupies 1 kB of memory, we can calculate how much memory a book will take

2/3kB=1 page\\ x kB=400 pages\\266.67 kB=400 pages

Now that we know that a book average file size is about 266,67 kB, we calculate how many of them can a 9 GB flash drive hold.

To do the calculation, we have to know how many kilobytes are in 9 gigabytes.

There is 1024 kilobytes in a megabyte, and 1024 megabytes in a gigabyte, so:

Memory_{in _kilobytes}^{} =1024\frac{kilobytes}{megabytes} *1024\frac{megabytes}{gigabytes}*9=9437184 kilobytes

Finally, knowing the average file size of a book and how much memory in kilobytes the 9 GB flash drive holds, we calculate how many books can it hold.

Books=\frac{Flash drive memory}{Filesize of a book} =\frac{9437184kilobytes}{266.67\frac{kilobytes}{book} } =35389,4 books

The flashdrive can hold 35389 400-pages-books, or 14155776 pages of typical text.
