In a 512 byte memory unit, in order to address each byte, there will be 512 locations (each one byte) ranging from 0 to 511.

Thus it will take 9 bits (2^9=512) to store the address within the unit.

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

A customer reports that recently several files cannot be accessed. The service technician decides to check the hard disk status
Lyrx [107]

Answer:

Back up the user data to removable disk

Explanation:

Before you work on a computer, especially anything that has to do with files not accessible, this might need to format the system because it might either be a virus or other forms of malware. Since backup was done to a different logical partition on the disk, the first thing to do before performing any diagnostic procedures on the disk is to back up the user data to a removable disk in order not to lose the information in the system.

you just bought a new hard drive for your computer you plan to use this as a secondary hard drive to store all um a files once i
mihalych1998 [28]
Well, you need to partition your hard drive. Partitioning your hard drive designates usable space on your hdd.

And you need to format your hard drive. Formatting installs a file system on to your hard drive, it allows the operating system to read, write and overall understand the data stored on the disk. Without it, an OS cannot keep track of file locations, nor can it typically identify already used sectors (space) on a hdd. 
However, neither of these two concepts are tests.
