Drag and drop the file from its current location on the computer. (If on Windows) there should be an icon on the top left corner of the CDs content window, click on Burn. It'll ask you what you want to name the CD and then choose "use the CD as a USB flash drive" or something similar after that the process will be done automatically

Given a typical magnetic hard drive with five platters, answer the following:

Nataly_w [17]

Answer:

Given the number of platters =5

A. Hence, the number of recording surface =10

B. number of read-write heads =10

C. Number of arms holding the read-write heads = 10

Explanation:

We know that number of recording surface = 2 *( number of platters)

= 2*5=10

And the number of read-write heads = number of recording surface= 10

Also, number of arms holding the read-write head = one for each read-write head= 10

And hence, the above answer.

A manufacturer of machine tools creates a spreadsheet of tools and the cost for those. The spreadsheet has four fields: name of

iragen [17]

The question above has multiple answers:

1. Sort the data in the field "name of the tool" in ascending order alphabetically.

2. Sort the data in the field “number of tools” in ascending order.

3. Sort the data in ascending order of cost per tool.

4. Sort the data in ascending order of total cost.

The answer is 3. Sort the data in ascending order of cost per tool

You can always make your spreadsheet work a bit more organized by sorting your data. In this case, what is required from the manufacturer of the tools is to sort the data so that someone else is able to find out which tool costs the most. Basically, the price of the tool which is the highest is required to be known. Therefore, the manufacturer of the tools should Sort the data in ascending order of cost per tool.

What was the first 1.0.1 version of openssl that was not vulnerable to heartbleed?

vovikov84 [41]

I suggest you to read OpenSSL changelogs to make it more clear. As there's not enough space to describe how it works. But heartbleed resistan version was 1.0.2, as I know.
