Most hard drives are divided into sectors of 512 bytes each. Our disk has a size of 16 GB. Fill in the blank to calculate how ma

ny sectors the disk has. Note: Your result should be in the format of just a number, not a sentence.
disk_size = 16*1024*1024*1024
sector_size = 512
sector_amount =
print(sector_amount)

The answer is pretty simple to achieve for this question. Multiply the disk size and then divide by the sector size - this will result in the total number of sectors. The reason the disk size shows “16*1024*1024*1024” is because there are 1024 bytes (B) in one kilobyte (1KB), and 1024KB in one megabyte (1MB), and 1024MB in one gigabyte (1GB). So, once you find out how many total bytes you have and then divide the total number of bytes by sector size (512), you will arrive at the answer.

n a​ poll, 6767​% of Internet users are more careful about personal information when using a public​ Wi-Fi hotspot. What is the
a_sh-v [17]

Answer:

The probability that among three randomly selected Internet​ users, at least one is more careful about personal information when using a public​ Wi-Fi hotspot is 0.964

If the survey subjects <em>volunteered</em> to​ respond , then those with the strongest opinions are most likely respond. The survey sample is then not randomly selected, the survey may have a <em>response bias.</em>

Explanation:

Let P(at least one is more careful about personal information when using a public​ Wi-Fi hotspot) denote the probability that among three randomly selected Internet​ users, at least one is more careful about personal information when using a public​ Wi-Fi hotspot, then we have the equation

P(at least one is more careful about personal information when using a public​ Wi-Fi hotspot) = 1 - P(none of the selected users is more careful about personal information when using a public​ Wi-Fi hotspot)

  • If 67​% of Internet users are more careful about personal information when using a public​ Wi-Fi, then 33% of them are not.

P(none of the selected users is more careful about personal information when using a public​ Wi-Fi hotspot) = 0.33^{3} ≈ 0.036

P(at least one is more careful about personal information when using a public​ Wi-Fi hotspot)  = 1 - 0.036 = 0.964

You're setting up some VMs to test an application you're considering making available to employees of the small company you work
IgorLugansk [536]

Answer:

Snapshots in VirtualBox, Hyper-V, and please check explanation.

Explanation:

You should never test the software on your PC as you never know what virus or threat they bring with them. Even when you are a software company and testing your own new software, you should use the VM, as it is safe. Any adverse effect can be tackled as the VM is made to be destroyed some day.

You can install numerous OS on your VM. The two best are certainly Virtual Box and the Hyper-V from VMWare. Remember, if you dont want to use the licensed version of certain OS, the trial versions are always available for free, and you can install them on the VMs.

There is a snapshot option on the VirtuabBOX. You are only required to create the snapshot after creating and configuring the VM. It supports Windows, Linux and Mac. So you can install almost any OS. However, VMWare Player does not support the Snapshot, but it provides s similar option known as Checkpoints. However, VMware Workstation supports Snapshots, though they might be costly.

If you are on OS X you can make use of Parallels.

However, never enable file sharing, and stay away from Bridge mode as well as never use your original accounts. File sharing will inject the malware if any to all places on network. The bridge mode connects the VM directly to the network, which otherwise remain hidden behind NAT. And use of personal accounts can cost you them, and this can be quite a big loss definitely.
